2022 Reading List

 

•Top Fiction: The Periodic Table, Primo Levi; These are just such a lovely set of stories of life great (war) and small (little relations) mixed in with a very personal and practical view of chemistry.

•Top Non-Fiction: Science and Human Behavior, B.F. Skinner; Even though this is dated and abandoned by modern psychology I find myself referring to this book more than others as it is so relevant to modern issues of AI, A/B Testing, and social media.

•Top Business: Treasure Islands, Nicholas Shaxson; I find this book persuasive on how financial malfeasance really does effect the real world we all have to live in.

Full List

 

1.Being Ram Dass, Ram Dass; A history of the counterculture by one of its icons. The mix of psychology, Buhdism, and Hinduism is peculiar and western and deeply personal to Ram Dass. It gave me insights and context into many personalities that influenced my early life: Leary, Muktanada, Keasey, Sai Baba, and ZBS productions. I was disappointed in his reliance on miracles to explain is devotion to Mittenanda, but it did show what was best in the self actualization movement and how to end well.

2.How to Read a Book, Mortimer J Adler; This time I spent quite a bit of attention on the notion of meaning, truth, and tradition. I believe if you read for meaning then Truth must be important to you, otherwise it is just entertainment. “Terms” can only achieve meaning and work within a given tradition or literature. Not all traditions are equal, and believe that just as mathematics is an overly specific language, you can reason and find truth within a tradition, but you can assess the falsity of a tradition by comparing it to pragmatic concerns with the physical world. This brings up concerns with a post modernists view has real consequences for reasoning about the natural world.

3.Paradise Lost, John Milton; This is the story we all know of the Bible that isn’t in the Bible. The ultimate sin is “pride,” Satan is the serpent and the seducer, Eve is blonde, and Jesus is doubly a king (of heaven and earth). The book does show off its time, clearly responding to the Glorious Revolution and anti-Catholic in nature, not mention Satan’s use of canon.

4.Science and Human Behavior, B.F. Skinner; This book encourages a purely external black box view of human being with consciousness and cognition as unimportant characteristics. What is impressive is not the shortcoming of this technique found in the last 70 years (CBT, Neural Imaging, Deep-Learning) but the shear efficacy of the approach at predicting and controlling human behavior. His lessons on the failures of punishment, and the importance of distributed control structures have become increasingly important as behavior controlling power has become much more centralized through entertainment and advertising companies.

5.The Rise of Rome, Anthony Everett; I modern telling of Republican Rome, that always starts with the myth and then explains the confirmation and differences of modern scholarship, but keeps to the classical narrative of Rome as that is what drives its importance to us. The importance of civilian Militia to Rome and their obsession with order and ambivalence to Greece are well described, the section on Hannibal was very good to make some sense of Punic/Phonetian/Catheginian/Spanish all fit together as the semetic rival of Rome.

6.The Aeneid, Virgil, tr. Cecil Day-Lewis; A great epic poem that feels a bit like a Greek epic remix with so many of Ulysses and other Greek adventures revisited, but characters have so many more inner voices and are so much more psychologically modern.

7.Great Courses Aeneid, prof Elizabeth Vandiver; It was interesting the degree the book was meant to justify Augustus Caesar, from simple examples like the Trojan Games, to explain the war on Carthage, and to justify the importance of Piety/Duty. Also the idea that he mixes both the Odyssey and the Iliad in reverse order to bring those stories to a wider audience is fascinating, and how this is the only details extent of the Trojan Horse.

8.The Perfect Storm, Sebastian Junger; A surprisingly amusing journalistic book of how to write a story about a lost boat in which we don’t know what happened and the whole story is done by simile of the similar stories. The stories of modern fishing and how hard and brutal life can still be due to weather and the realities of the sea.

9.Children of Gebelawi, Naguib Mahfouz; A story that mostly uses ordinary people in a realistic violent patriarchy as metaphor for the Judo-Christian-Islamic tradition and by extension our modern world. The story creates an emotional understanding of the middle eastern cultures of what is both loved and hated within their own culture, but with a desire for freedom and fairness that externally we assume means independence.

10.A True History of the United States: Indigenous Genocide, Racialized Slavery, Hyper-Capitalism, Militarist Imperialism and Other Overlooked Aspects of American Exceptionalism, Daniel A. Sjursen; An attempt at a 21st century Progressive’s history of the United States. It feels a bit awkward as it tells the story of America through its military conflicts, which doesn’t always align well with the important events for its oppressed peoples, also the book does not define nore justify concern about equity or hyper-capitalism. More complete than Zinn’s book but still not a stand-alone history and starts to feel journalistic starting with George Bush Jr. The pre-Bill of rights section is by far the best covering the complexities of colonial times and an unusually in-depth analysis of the Spanish American war. FDR and Russian apologist tendencies are mediocre.

11.Economics Facts and Fallacies, Thomas Sowell; Fairly basic economic analysis of tradeoffs and incentives, from a very conservative African American Economist. Generally well argued and very clear, though not always covering all the data. Not very persuasive on executive pay, excellent examples of the problems with statistical comparisons for economic development for wages, women, and blacks around non-comparable demographics age, education, marriage status. I agree with his analysis that the real problem with gender pay inequality is a problem with marriage and motherhood, I disagree that this is not a problem.

12.Arabian Nights and Days, Mafouz Naguib; A selection of 1001 nights stories, converted to a slightly more modern and real world and given specific moral meanings. The themes of the corruption of power from position, wealth, or invisibility caps is very present. The Sultan is ultimately creating corruption through his abuse of power, the book leaves unanswered to what degree we can ever achieve forgiveness for our sins.

13.The Koran, Mohamed tr. N.J. Dawood; A much more clear and prescriptive religious text than the bible. The retold stories include Adam and Satan, where Satan denies man's dominion over the earth, Moses where even clear miracles are denied, Jesus has a virgin mother but got has no son nor wife. Alms/Charity are always repeated ass is the care of orphans.

14.Cleopatra: A Biography, Michael Grant; Tries to tell the story from Cleopatra’s point of view, relying heavily on an optimistic strategic view of what could have been to her interest. In this story Cleopatra is the Hellenic Queen and represents the traditions of Alexander. She becomes a competent extension of the Tolomeis traditions working hard with vision and ruthlessness to maintain the power of her family within its own traditions. Relied surprisingly heavily on coin evidence and it was fun though not inherently convincing to mix in poetry through the ages to describe the possible scenes.

15.The Canterbury Tales, Geofrey Chaucer; Modern spelling and pronunciation, but original words. Was excellent storytelling, a collection of short stories that speak to each other as a series. Curious mixture of baudy and pious that feels surprisingly like Shakespeare (also the overlap of historic and classical themes). Many if not most of the stories are taken from other sources and are reset to give them a specific impact, that still resonates until today with the humor~ and lessons even if we moderns miss the stereotypes of the time.

16.Cleopatra: A Life, Stacy Schiff; This was a specific attempt at a positive view of Cleopatra as a competent ruler. The author correctly interprets that the primary stories we have have all been tainted by a conqueror who needed to have a villain to justify his war. Her arguments are convincing that Cleopatra was an active and judicious ruler working for her own self interest, she expanded her empire substantially, she reduced her own infighting, increased wealth and power though she eventually lost the entire kindgdom.

17.Immune, Philipp Dettmer; This is narrative biology, really optimized for kids to learn their first cellular system. It is up to date and current on the science but eliminates the biochemistry on the immune system, I learned about feedback loop of Macrophages/Neutrophil, Dendritic messengers, Lymphocyte (T&B) activation with silly analogies that are memorable.

18.The Bhagavad Gita, Traditional tr. Swami Swarupananda; It is interesting to read the raw text with its curious mixtures of things. I was most surprised by the mixing of caste called out as one of the obvious and greatest sins. I also found the mixing of the ideas that I am more familiar with from Chinese traditions such as the importance of duty (confucianism) and unattachment (buddhism). The lesson I took the most was the focus on accomplishment of duty without the aim for attaining Glory of the universe even if evil actions are taken, they can be forgiven if they follow the glorification of god. This produces a strong social structure without revenge and incrimination. This is a very un-Christian solution to the problem of Evil, as it always exists with us, and it exists without intent, but we can only overcome it (not individually) by maintaining society/duty.

19.A Short History of Artificial Intelligence, Michael Wooldridge; This books feels weak when compared to Mitchel’s AI book as it fails to really explain how different techniques work and covers a bit of the same history. This book is more in the history and makes it much more clear how much AI has always been part of mainstream software history, as the “Intelligence” has never been precise, the best insight of this book was the importance of computation complexity theory on the limits of AI, and why a combination of deep neural nets and monte-carlo strategies have only superficially solved the problem for some very deterministic cases like games. The second big insight was how much Brook’s strategy of interactive “intelligence” (roomba like) produces powerful results, but has no theoretical structure for progression.

20.The Sandman (01-75) & Audio Book, Neil Gaiman; Literary Horror, but still a comic book. The audiobook felt so much darker than the comic. It is a writers book, it is about the power of stories, both to create the gods and let them live on, the stories we create to punish ourselves (hell, furies) and the nightmares to guide us, and how end of each story is a little death that doesn’t

21.The Peloponnesian War, Thucydides tr. Benjamin Jowett; this almost feels like a modern history other than the unquoted speeches that are one the best parts of the book, the various rhetorical devices are masterworks. For Thucydides the war is a conflict between the slow alliance building oligarchs of Sparta and the mercurial imperialists of Athens. One offering honor and stability and other wealth and democracy. Nicias is my favorite General who doesn’t want to go to war but tries and fails. It feels a bit like a modern history book, and it is a great adventure story in its own right with detailed local politics with twisting alliances.

22.Treasure Islands, Nicholas Shaxson; I do prefer the author's term secrecy jurisdiction s over Tax havens. It makes it clear it is a way to legally hide things from laws. Tax is lost which while that has negative consequences especially for the poor and weak it is side story from the evasion of legislation, and encouraging crime and corruption. The author's pro legislation, kaysien, labour movement opinions distract from how lack of rule of law hurt us all, even Delaware, Zürich, and the city of London.

23.Old Man's War Series (Old Man’s War, The Ghost Brigades, The Last Colony, Zoe’s Tale, The Human Division, The End of All Things), John Scalzi; The series has too much plot and not enough character or setting, it goes from super soldier, to frontier, to teenage team, to band of misfits save the world adventure stories. The world is a screed against sectionalism, and panegyric to individualism and the power of choice. The tension between these drives the relationships with the Aliens and development of human society.

24.Do Dice Play God, Ian Stewart; This is a book of practical mathematics, it focuses on statistics, unlike Taleb who really focuses on the meaning of uncertainty, this explains a difference between randomness (true incompressible information) and unpredictability (deterministic chaos). It goes well beyond the history of statistics and into dynamic equations and partial differential estimations and the how and why these techniques have been developed. Basically the practical side of the most advanced mathematics I studied. Stewart is determinist and makes an argument we should look for deterministic chaos in systems such as quantum.

25.Superior: the return of race science, Angela Saini; The book is a journalist look into biological racism's history, disproof, and revival. The author approaches the subject as a Briton of Indian decent, points out the two biggest proponents of eugenics we're the USA and Nazi Germany, how statistically there is more variation within any identified racial group than between any of them and how race consciousness especially in medicine combined with new national narratives is bringing back biological (scientific) racism.

26.Under the Volcano, Malcolm Lowery; This is a very lyrical novel, that has great depth of character stuffed into 1 day and 1 hour a year later. The story is set with the tension of 1938 as an implicit background, and individuals whose horrible fate seems avoidable if they could just for a moment be something other than their ordinary selves. The Consul can observe and analyze the world in detail, but cannot make even simple choices in his anxiety and alcoholism, Yvonne has independently struck upon the same idea as the Consul to escape but cannot articulate it to him in his malaise to force it to reality, Hugh wants desperately to make his mark on the world, but always chooses the hopeless irrelevant path of history, when opportunity is so close but he cannot know. It leaves me thinking of how many decisions in our life are close to something that could make us better, but the default is to remain stuck where we are.

27.American Cartel, Scott Higham, Sari Horwitz; It is a two part story, starts with a crime novel and switches to an unfinished courtroom drama. I can almost sympathize with the manufacturers and distributors' claim that they are not responsible for prescribing or handing out the drugs, but the ‘71 controlled substance act gave the distributors the impossible task of regulating the distribution of what made them money. The story doesn’t explain why those groups went to Trump, but the ineffectiveness of the law to curb the distribution and death (even when doctors and pharmacists could be jailed), the revolving door of regulators and advisors, the lobbying to make it impossible to enforce the laws left many communities with nothing but anger and woe.

28.Understanding Power, Noam Chomsky; A primer on American leftist ideology, and a guidebook for Q-Anon. I did not know Chomsky’s past in the peace movement, or the American Communist party. Fundamentally he is an Anrcho-Syndicalist who has extreme faith in the ability of planners. He is very good at guiding a reader through institutional analysis, but as the book progresses he takes to much of the aims and institutions as responsibility for the outcomes. “they” must of planned it and made it happen. He is well read in history but provides a sometimes bizarre but not unsupportable view of facts, like people forced off farms into industry. His anti-Expert views, then demanding that aims can easily become results creates a perfect motte-bailey argument pattern for conspiracy theories, now popularized by the far right.

29.The Hunchback of Notre Dame, Victor Hugo; An ode to Medieval Paris, with a believable world with ridiculously over the top operatic characters and plot. Esmerelda and Frolio are both entirely corrupted by lust, there is no real redemption for Quasimodo who overcomes his position in society that believes that the soul must follow the body, leaving everything in tragedy. Even while maudlin over the top the details and dialog are fantastic, the philosophizing on architecture and poets is hilarious and insightful, I am left of thinking how the times and place make the man.

30.How Numbers Work, New Scientist; Fun superficial survey of modern mathematics, some little history like base10 and decimals moving from China to India to Europe, a very consise explanation ofhow set theory can ground numbers, cute applications of stats to the real world, the big names like Hilbert and Weil get little vignettes, the phycs and philosophy was just weak, casual read I recommend it to my kids

31.Proof: The Science of Booze, Adam Rogers; This was a fun book, mycology and biochemistry. The importance of the yeast, how the enzymes of malt work, good fun casual science read with a little bit of politics and history thrown in.

32.Invisible Man, Ralph Ellison; re-read last time I read it I was in high school, and I barely remember it but it is fantastic, I would classify it more as a middle-age book than a coming of age book. It is deeply about the African American experience that still exists today, but that is used to show sharp relief of more general problems of how we find our place in society,. The anonymous author is invisible in many ways, the biggest is that he cannot be recognized for who he is, unlike the modern focus on identitarian politics. This focus is on how our history must effect us but we still desire freedom and recognition as individuals, not live other peoples dreams for them. I find the section on the inadequacy of the freedom of the duplicitous hipster Rinehart as inadequate, interesting and convincing.

33.Che Guevara: A Revolutionary Life, Jon Lee Anderson; This was an excellent biography that gives strong historical perspective and evaluates the existing controversies. Che comes out as an amazing leader through his passion for a fair society for socialist man Well done biography giving a sense of characters and balancing the historic controversies of the subject. I very much appreciated the level of context of the Americas in the ‘50s as a background setting. Che comes through as a quirky and unique individual, who provided leadership through strong conviction, and unflinching dedication to his ideals. The story is ultimately tragic, not due to the death and horror that he wrought, but how in life we can only learn one set of hard won lessons of loyalty and universally high standards for mankind that served Che so well in Cuba failed utterly in the Congo and Bolivia leading to his failure and death. His thesis of “Gorilla war as the crucible to forge the socialist man” is both true and inadequate. It was true as only extreme hardship could provide an environment to force people to work together wholeheartedly as one without conventions and institutions, but inadequate for creating a complete society.

34.The World According to Physics, Jim Al-Khalili; This a book about physics in 2020’s, it explains the 3 foundations of Relativity, Quantum, and Thermodynamics at their current state for the non-mathematical. I think the failure to address the dimensionality problems of Superstrings and the divide by 0 problems of merging Relativity and Quantum was sad even for a non-mathematical summary, but he does a great job of addressing the big problems of physics why unified theories are hard and desirable, why quantum is so important to the real world, the realists demands, why esoteric particles are so important to find, why holographic theory is important for cross-over from the large to the small.

35.The Periodic Table, Primo Levi; a beautiful collection of stories about life, work, the material world, growing up, and growing old. The background of his experience in concentration camp keeps the story somber, but his playful look at his youth and becoming a chemist, and making friends keeps the collection cheerful and insightful to human characters. Vanadium is such a short and concise look at many of the complexities of coming to terms with the ordinary horror of IG Farben employees and the inability to fully appreciate the enormity of the camps.

36.Talent is Overrated, Geoff Colvin; I was looking for ideas to improve underperforming teams, what I got was a refresher on the importance of deliberate practice: intentional, responsive, specific, and repeatable practice is what makes great performance. General skills/IQ allow people to get to a basic level fast, but does not speed up specific performance, also specific practice can even overcome much of the general failures of aging. The ability to apply this to teams was only through simile and didn‘t provide direct guidance. But is a good reminder of just how important intentionality is any result.

37.101 Wilderness Survival Skills, Kevin Estell; This was 80% covered in the old Boy Scout handbook, it reminded me of a set of skills that do make me feel more comfortable outside even if I rarely use them. I agree with the incredible nature of 550 paracord, but it is a bit more “survivalist” oriented than my relationship with the outside. It did make me think about emergency preparedness and the basic usefulness of knife, “cord”, and fire skills. I don’t really know how to teach fire skills to my kids in our modern low fire world.

38.Baltasar and Blimunda, José Saramago; The compelling plot is driven by the magical realism narrative and love of Baltasar and Blimunda, but the main thrust of the book is the condemnation of the church & monarchy failing to take care of the people and the great waste of wealth. The naive and omniscient across time narrator sets a sarcastic tone to the book to offset the saccharin love of the main characters, but their relationships with others are subtle and realistic: the monk, the music master, the sister, the father, and the workers are all beautiful vignettes.

39.The New Puritans: How the Religion of Social Justice Captured the Western World, Andrew Doyle; A very contemporary work with an obnoxious beginning. The worst parts of the book are the complaints and examples of Woke aggression, the best part is the intellectual history of related topics and terms. I am unpersuaded that calling people their preferred pronouns is anything other than polite, but I do agree it should not be legally enforced, which leads to my strong sympathies with defense of Liberal Enlightenment ideology and primacy of reasoned argument as a method of social and material progress that must be defended and encouraged.

40.What I Didn’t Learn in Business School, Jay B. Barney; A fictional novel of management consultants as a pedagogical tool for business. It works OK, to explain the importance of real world experience to utilize NPV, 5-Forces, etc…, the need for diverse experiences to get at data, and the unrelenting importance of relationships and teamwork.

41.The Golden Notebook, Doris Lessing; This is surprisingly readable, technically complicated book, the divisions into a writer’s versions of herself and multiple fictionalized versions of the characters lives, reactions and experience divided up by themes. The themes that left an impression on me were those of the communists and feminism. The focus on ideology that is supposed to be good but became corrupt echos of itself, self aware and embarrassed of its own failure. The relations between genders is deeply personal leaving open tradeoffs of independence and community, the social needs and expectations that come bundled in ways that even when the law allows cannot be taken apart leaving individuals unsatisfied. Watching the world the views of an empath who knows what everyone feels from the their body languages and is intellectual aware of how she is influenced by others but incapable of resisting was well portrayed.

Brief synthesis

 

The Ħal Saflieni Hypogeum (underground cemetery) was discovered in 1902 on a hill overlooking the innermost part of the Grand Harbour of Valletta, in the town of Paola. It is a unique prehistoric monument, which seems to have been conceived as an underground cemetery, originally containing the remains of about 7,000 individuals. The cemetery was in use throughout the Żebbuġ, Ġgantija and Tarxien Phases of Maltese Prehistory, spanning from around 4000 B.C. to 2500 B.C.

 

Originally, one entered the Ħal Saflieni Hypogeum through a structure at ground level. Only a few blocks of this entrance building have been discovered, and its form and dimensions remain uncertain. The plan of the Hypogeum itself is a series of three superimposed levels of chambers cut into soft globigerina limestone, using only chert, flint and obsidian tools and antlers. The earliest of the three levels is the uppermost, scooped out of the brow of a hill. A number of openings and chambers for the burial of the dead were then cut into the sides of the cavity.

 

The two lower levels were also hewn entirely out of the natural rock. Some natural daylight reached the middle level through a small opening from the upper level, but artificial lighting must have been used to navigate through some of the middle level chambers and the lowest level, which is 10.60 m below the present ground level.

 

One of the most striking characteristics of the Ħal Saflieni Hypogeum is that some of the chambers appear to have been cut in imitation of the architecture of the contemporary, above-ground megalithic temples. Features include false bays, inspired by trilithon doorways, and windows. Most importantly, some of the chambers have ceilings with one ring of carved stone overhanging the one below to imitate a roof of corbelled masonry. This form echoes the way in which some of the masonry walls of the contemporary above-ground temple chambers are corbelled inwards, suggesting that they too were originally roofed over.

 

Some of the walls and ceilings of the chambers were decorated with spiral and honey-comb designs in red ochre, a mineral pigment. These decorations are the only prehistoric wall paintings found on the Maltese Islands. In one of these decorated chambers, there is a small niche which echoes when someone speaks into it. While this effect may not have been created intentionally, it may well have been exploited as part of the rituals that took place within the chambers.

 

Excavation of the Ħal Saflieni Hypogeum produced a wealth of archaeological material, including numerous human bones, which suggests that the burial ritual had more than one stage. It appears that bodies were probably left exposed until the flesh had decomposed and fallen off. The remaining bones and what appear to be some of the personal belongings were then gathered and buried within the chambers together with copious amounts of red ochre. The use of ochre seems to have been a part of the ritual, perhaps to infuse the bones with the colour of blood and life. Individuals were not buried separately, but piled onto each other.

 

Artefacts recovered from the site include pottery vessels decorated in intricate designs, shell buttons, stone and clay beads and amulets, as well as little stone carved animals and birds that may have originally been worn as pendants. The most striking finds are stone and clay figurines depicting human figures. The most impressive of these figures is that showing a woman lying on a bed or ‘couch’, popularly known as the ‘Sleeping Lady’. This figure is a work of art in itself, demonstrating a keen eye for detail.

 

Criterion (iii): The Ħal Saflieni Hypogeum is a unique monument of exceptional value. It is the only known European example of a subterranean ‘labyrinth’ from about 4,000 B.C. to 2,500 B.C. The quality of its architecture and its remarkable state of preservation make it an essential prehistoric monument.

 

Integrity

 

The Ħal Saflieni Hypogeum is one of the best preserved and most extensive environments that have survived from the Neolithic. With the exception of the fragmentary remains of the above-ground entrance, all the key attributes of the property, including the architectural details and painted wall decorations, have remained intact within the boundaries.

 

The main threats to the preservation of the Ħal Saflieni Hypogeum are the fluctuating temperature and relative humidity levels within the site, as well as water infiltration and biological infestations.

 

Authenticity

 

The Ħal Saflieni Hypogeum is one of the two most important prehistoric burial sites in the Maltese islands and is very well preserved, unlike the fragmentary remains that usually survive from the above-ground structures of this period.

 

The unusual preservation of the rock-cut chambers allows the study of a system of interconnecting spaces very much as they were conceived and experienced by a Neolithic mind. The imitation of the interior of a megalithic temple built above ground not only provides evidence on the corbelling system that was used to roof the temples, but is also important in terms of the development of human processes of cognition and representation.

 

The Ħal Saflieni Hypogeum has also yielded several important artefacts of great artistic significance. Foremost amongst these is the so-called ‘Sleeping Lady’, a miniature ceramic figurine that is widely held to be one of the great masterpieces of prehistoric anthropomorphic representation.

 

Protection and management requirements

 

The principal legal instrument for the protection of cultural heritage resources in Malta is the Cultural Heritage Act (2002), which provides for and regulates national bodies for the protection and management of cultural heritage resources. Building development and land use is regulated by the Environment and Development Planning Act (2010 and subsequent amendments), which provides for and regulates the Malta Environment and Planning Authority. The Ħal Saflieni Hypogeum is protected by a buffer zone, and both the Ħal Saflieni Hypogeum and its buffer zone are formally designated by the Malta Environment and Planning Authority as a Grade A archaeological site, which means they are subject to wide-ranging restrictions of building development.

 

A programme of monitoring and research, launched in order to understand the microclimate of the Hypogeum, was followed by a project for the conservation of the property, designed and implemented in the 1990s. Houses directly above the site were acquired and dismantled; light levels within the property are strictly controlled; and visitor numbers limited. These measures have helped to maintain stable temperature and humidity levels, which continue to be monitored closely.

The ring-tailed lemur (Lemur catta) is a medium- to larger-sized strepsirrhine (wet-nosed) primate, and the most internationally-recognized lemur species, owing to its long, black-and-white, ringed tail. It belongs to Lemuridae, one of five lemur families, and is the only member of the Lemur genus. Like all lemurs, it is endemic to the island of Madagascar, where it is endangered. Known locally in Malagasy as maky ([makʲ] ⓘ, spelled maki in French) or hira, it ranges from gallery forests to spiny scrub in the southern regions of the island. It is omnivorous, as well as the most adapted to living terrestrially of the extant lemurs.

 

The ring-tailed lemur is highly social, living in groups of up to 30 individuals. It is also a female-dominant species, a commonality among lemurs. To keep warm and reaffirm social bonds, groups will huddle together. Mutual grooming is another vital aspect of lemur socialization (as with all primates), reaffirming social and familial connections, while also helping rid each other of any potential insects. Ring-tailed lemurs are strictly diurnal, being active exclusively during daylight hours. Due to this lifestyle, they also sunbathe; the lemurs can be observed sitting upright on their tails, exposing their soft, white belly fur towards the sun. They will often also have their palms open and eyes gently closed. Like other lemurs, this species relies strongly on their sense of smell, and territorial marking, with scent glands, provides communication signals throughout a group’s home range. The glands are located near the eyes, as well as near the anus. The males perform a unique scent-marking behavior called spur-marking, and will participate in stink fights by dousing their tails with their pheromones and “wafting” it at opponents. Additionally, lemurs of both sexes will scent-mark trees, logs, rocks or other objects by simply rubbing their faces and bodies onto it, not unlike a domestic cat.

 

As one of the most vocal primates, the ring-tailed lemur uses numerous vocalizations, including calling for group cohesion and predator alarm calls. Experiments have shown that the ring-tailed lemur, despite the lack of a large brain (relative to simiiform primates), can organize sequences, understand basic arithmetic operations, and preferentially select tools based on functional qualities.

 

Despite adapting to and breeding easily under captive care (and being the most popular species of lemur in zoos worldwide, with more than 2,000 captive-raised individuals), the wild population of ring-tailed lemur is listed as endangered by the IUCN Red List, due to habitat destruction, local hunting for bushmeat and the exotic pet trade. As of early 2017, the population in the wild is believed to have crashed to as low as 2,000 individuals due to these reasons, making them far more critically endangered. Local Malagasy farmers and logging industries frequently make use of slash and burn deforestation techniques, with smoke being visible on the horizon on most days in Madagascar, in an effort to accommodate livestock and to cultivate larger fields of crops.

 

Etymology

Although the term "lemur" was first intended for slender lorises, it was soon limited to the endemic Malagasy primates, which have been known as "lemurs" ever since. The name derives from the Latin term lemures, which refers to specters or ghosts that were exorcised during the Lemuria festival of ancient Rome. According to Carl Linnaeus's own explanation, the name was selected because of the nocturnal activity and slow movements of the slender loris. Being familiar with the works of Virgil and Ovid and seeing an analogy that fit with his naming scheme, Linnaeus adapted the term "lemur" for these nocturnal primates. However, it has been commonly and falsely assumed that Linnaeus was referring to the ghost-like appearance, reflective eyes, and ghostly cries of lemurs. It has also been speculated that Linnaeus may also have known that some Malagasy people have held legends that lemurs are the souls of their ancestors, but this is unlikely given that the name was selected for slender lorises from India. The species name, catta, refers to the ring-tailed lemur's cat-like appearance. Its purring vocalization is similar to that of the domestic cat.

 

Following Linnaeus's species description, the common name "ring-tailed maucauco" was first penned in 1771 by Welsh naturalist Thomas Pennant, who made note of its characteristic long, banded tail. (The term "maucauco" was a very common term for lemurs at this time.) The now universal English name "ring-tailed lemur" was first used by George Shaw in his illustrated scientific publication covering the Leverian collection, which was published between 1792 and 1796.

 

Evolutionary history

All mammalian fossils from Madagascar come from recent times.[11] Thus, little is known about the evolution of the ring-tailed lemur, let alone the rest of the lemur clade, which comprises the entire endemic primate population of the island. However, chromosomal and molecular evidence suggest that lemurs are more closely related to each other than to other strepsirrhine primates. For this to have happened, it is thought that a very small ancestral population came to Madagascar via a single rafting event between 50 and 80 million years ago. Subsequent evolutionary radiation and speciation has created the diversity of Malagasy lemurs seen today.

 

According to analysis of amino acid sequences, the branching of the family Lemuridae has been dated to 26.1 ±3.3 mya while rRNA sequences of mtDNA place the split at 24.9 ±3.6 mya. The ruffed lemurs are the first genus to split away (most basal) in the family, a view that is further supported by analysis of DNA sequences and karyotypes. Additionally, Molecular data suggests a deep genetic divergence and sister group relationship between the true lemurs (Eulemur) and the other two genera: Lemur and Hapalemur.

 

The ring-tailed lemur is thought to share closer affinities to the bamboo lemurs of the genus Hapalemur than to the other two genera in its family. This has been supported by comparisons in communication, chromosomes, genetics, and several morphological traits, such as scent gland similarities. However, other data concerning immunology and other morphological traits fail to support this close relationship. For example, Hapalemur species have short snouts, while the ring-tailed lemur and the rest of Lemuridae have long snouts. However, differences in the relationship between the orbit (eye socket) and the muzzle suggest that the ring-tailed lemur and the true lemurs evolved their elongated faces independently.

 

The relationship between the ring-tailed lemur and bamboo lemurs is the least understood. Molecular analysis suggests that either the bamboo lemurs diverged from the ring-tailed lemur, making the group monophyletic and supporting the current two-genera taxonomy, or that the ring-tailed lemur is nested in with the bamboo lemurs, requiring Hapalemur simus to be split off into its own genus, Prolemur.

 

The karyotype of the ring-tailed lemur has 56 chromosomes, of which four are metacentric (arms of nearly equal length), four are submetacentric (arms of unequal length), and 46 are acrocentric (the short arm is hardly observable). The X chromosome is metacentric and the Y chromosome is acrocentric.

 

Taxonomic classification

Linnaeus first used the genus name Lemur to describe "Lemur tardigradus" (the red slender loris, now known as Loris tardigradus) in his 1754 catalog of the Museum of King Adolf Frederick. In 1758, his 10th edition of Systema Naturae listed the genus Lemur with three included species, only one of which is still considered to be a lemur while another is no longer considered to be a primate. These species include: Lemur tardigradus, Lemur catta (the ring-tailed lemur), and Lemur volans (the Philippine colugo, now known as Cynocephalus volans). In 1911, Oldfield Thomas made Lemur catta the type species for the genus, despite the term initially being used to describe lorises. On January 10, 1929, the International Commission on Zoological Nomenclature (ICZN) formalized this decision in its publication of Opinion 122.

 

The ring-tailed lemur shares many similarities with ruffed lemurs (genus Varecia) and true lemurs (genus Eulemur), and its skeleton is nearly indistinguishable from that of the true lemurs. Consequently, the three genera were once grouped together in the genus Lemur and more recently are sometimes referred to as subfamily Lemurinae (within family Lemuridae). However, ruffed lemurs were reassigned to the genus Varecia in 1962, and due to similarities between the ring-tailed lemur and the bamboo lemurs, particularly in regards to molecular evidence and scent glands similarities, the true lemurs were moved to the genus Eulemur by Yves Rumpler and Elwyn L. Simons (1988) as well as Colin Groves and Robert H. Eaglen (1988). In 1991, Ian Tattersall and Jeffrey H. Schwartz reviewed the evidence and came to a different conclusion, instead favoring to return the members of Eulemur and Varecia to the genus Lemur. However, this view was not widely accepted and the genus Lemur remained monotypic, containing only the ring-tailed lemur. Because the differences in molecular data are so minute between the ring-tailed lemur and both genera of bamboo lemurs, it has been suggested that all three genera be merged.

 

Because of the difficulty in discerning the relationships within family Lemuridae, not all authorities agree on the taxonomy, although the majority of the primatological community favors the current classification.

In 1996, researchers Steven Goodman and Olivier Langrand suggested that the ring-tailed lemur may demonstrate regional variations, particularly a high mountain population at Andringitra Massif that has a thicker coat, lighter coloration, and variations in its tail rings. In 2001, primatologist Colin Groves concluded that this does not represent a locally occurring subspecies. This decision was later supported by further fieldwork that showed that the differences fell within the normal range of variation for the species. The thicker coat was considered a local adaptation to extreme low temperatures in the region, and the fading of the fur was attributed to increased exposure to solar radiation. Additional genetic studies in 2000 further supported the conclusion that population did not vary significantly from the other ring-tailed lemur populations on the island.

 

Anatomy and physiology

The ring-tailed lemur is a strepsirrhine primate, with a protruding muzzle and a wet nose. Top is the skull.

The ring-tailed lemur is a relatively large lemur. Its average weight is 2.2 kilograms (4.9 lb). Its head–body length ranges between 39 and 46 cm (15 and 18 in), its tail length is 56 and 63 cm (22 and 25 in), and its total length is 95 and 110 cm (37 and 43 in). Other measurements include a hind foot length of 102 and 113 mm (4.0 and 4.4 in), ear length of 40 and 48 mm (1.6 and 1.9 in), and cranium length of 78 and 88 mm (3.1 and 3.5 in).

 

The species has a slender frame and narrow face, fox-like muzzle. The ring-tailed lemur's trademark—a long, bushy tail—is ringed in alternating black and white transverse bands, numbering 12 or 13 white rings and 13 or 14 black rings, and always ending in a black tip. The total number of rings nearly matches the approximate number of caudal vertebrae Its tail is longer than its body and is not prehensile. Instead, it is only used for balance, communication, and group cohesion.

 

The pelage (fur) is so dense that it can clog electric clippers. The ventral (chest) coat and throat are white or cream. The dorsal (back) coat varies from gray to rosy-brown, sometimes with a brown pygal patch around the tail region, where the fur grades to pale gray or grayish brown. The dorsal coloration is slightly darker around the neck and crown. The hair on the throat, cheeks, and ears is white or off-white and also less dense, allowing the dark skin underneath to show through. The muzzle is dark grayish and the nose is black, and the eyes are encompassed by black triangular patches. Facial vibrissae (whiskers) are developed and found above the lips (mystacal), on the cheeks (genal), and on the eyebrow (superciliary). Vibrissae are also found slightly above the wrist on the underside of the forearm. The ears are relatively large compared to other lemurs and are covered in hair, which has only small tufts if any. Although slight pattern variations in the facial region may be seen between individuals, there are no obvious differences between the sexes.

 

Unlike most diurnal primates, but like all strepsirrhine primates, the ring-tailed lemur has a tapetum lucidum, or reflective layer behind the retina of the eye, that enhances night vision. The tapetum is highly visible in this species because the pigmentation of the ocular fundus (back surface of the eye), which is present in—but varies between—all lemurs, is very spotty. The ring-tailed lemur also has a rudimentary foveal depression on the retina. Another shared characteristic with the other strepsirrhine primates is the rhinarium, a moist, naked, glandular nose supported by the upper jaw and protruding beyond the chin. The rhinarium continues down where it divides the upper lip. The upper lip is attached to the premaxilla, preventing the lip from protruding and thus requiring the lemur to lap water rather than using suction.

 

The skin of the ring-tailed lemur is dark gray or black in color, even in places where the fur is white. It is exposed on the nose, palms, soles, eyelids, lips, and genitalia. The skin is smooth, but the leathery texture of the hands and feet facilitate terrestrial movement. The anus, located at the joint of the tail, is covered when the tail is lowered. The area around the anus (circumanal area) and the perineum are covered in fur. In males, the scrotum lacks fur, is covered in small, horny spines, and the two sacs of the scrotum are divided. The penis is nearly cylindrical in shape and is covered in small spines, as well as having two pairs of larger spines on both sides. Males have a relatively small baculum (penis bone) compared to their size. The scrotum, penis, and prepuce are usually coated with a foul-smelling secretion. Females have a thick, elongated clitoris that protrudes from the labia of the vulva. The opening of the urethra is closer to the clitoris than the vagina, forming a "drip tip".

 

Females have two pairs of mammary glands (four nipples), but only one pair is functional. The anterior pair (closest to the head) are very close to the axillae (armpit). Furless scent glands are present on both males and females. Both sexes have small, dark antebrachial (forearm) glands measuring 1 cm long and located on the inner surface of the forearm nearly 25 cm (9.8 in) above the wrist joint. (This trait is shared between the Lemur and Hapalemur genera.) The gland is soft and compressible, bears fine dermal ridges (like fingerprints), and is connected to the palm by a fine, 2 mm–high, hairless strip. However, only the male has a horny spur that overlays this scent gland. The spur develops with age through the accumulation of secretions from an underlying gland that may connect through the skin through as many as a thousand minuscule ducts. The males also have brachial (arm) glands on the axillary surface of their shoulders (near the armpit). The brachial gland is larger than the antebrachial gland, covered in short hair around the periphery, and has a naked crescent-shaped orifice near the center. The gland secretes a foul-smelling, brown, sticky substance. The brachial gland is barely developed if present at all in females. Both sexes also have apocrine and sebaceous glands in their genital or perianal regions, which are covered in fur.

 

Its fingers are slender, padded, mostly lacking webbing, and semi-dexterous with flat, human-like nails. The thumb is both short and widely separated from the other fingers. Despite being set at a right angle to the palm, the thumb is not opposable since the ball of the joint is fixed in place. As with all strepsirrhines, the hand is ectaxonic (the axis passes through the fourth digit) rather than mesaxonic (the axis passing through the third digit) as seen in monkeys and apes. The fourth digit is the longest, and only slightly longer than the second digit. Likewise, the fifth digit is only slightly longer than the second. The palms are long and leathery, and like other primates, they have dermal ridges to improve grip. The feet are semi-digitigrade and more specialized than the hands. The big toe is opposable and is smaller than the big toe of other lemurs, which are more arboreal. The second toe is short, has a small terminal pad, and has a toilet-claw (sometimes referred to as a grooming claw) specialized for personal grooming, specifically to rake through fur that is unreachable by the mouth. The toilet-claw is a trait shared among nearly all living strepsirrhine primates. Unlike other lemurs, the ring-tailed lemur's heel is not covered by fur.

Like other lemurs, the ring-tailed lemur has a claw-like nail (toilet-claw) on its second toe (left) and dermal ridges on its hands to improve its grip (center). Unlike other lemurs, it lacks fur on its heel (right).

Dentition

The front, lower dentition includes a toothcomb (4 incisors and 2 canine teeth), while the first premolars resemble canines.

The ring-tailed lemur has a dentition of

2.1.3.3

2.1.3.3

 × 2 = 36, meaning that on each side of the jaw it has two incisors, one canine tooth, three premolars, and three molar teeth.[3] Its deciduous dentition is

2.1.3

2.1.3

 × 2 = 24. The permanent teeth erupt in the following order: m 1/1 (first molars), i 2/2 (first incisors), i 3/3 (second incisors), C1 (upper canines), m 2/2 (second molars), c1 (lower canines), m 3/3 (third molars), p 4/4 (third premolars), p 3/3 (second premolars), p 2/2 (first premolars).

 

Its lower incisors (i1 and i2) are long, narrow, and finely spaced while pointing almost straight forward in the mouth (procumbent). Together with the incisor-shaped (incisiform) lower canines (c1), which are slightly larger and also procumbent, form a structure called a toothcomb, a trait unique to nearly all strepsirrhine primates. The toothcomb is used during oral grooming, which involves licking and tooth-scraping. It may also be used for grasping small fruits, removing leaves from the stem when eating, and possibly scraping sap and gum from tree bark. The toothcomb is kept clean using a sublingual organ—a thin, flat, fibrous plate that covers a large part of the base of the tongue. The first lower premolar (p2) following the toothcomb is shaped like a canine (caniniform) and occludes the upper canine, essentially filling the role of the incisiform lower canine. There is also a diastema (gap) between the second and third premolars.

 

The upper incisors are small, with the first incisors space widely from each other, yet closely to the second incisors . Both are compressed buccolingually (between the cheek and the tongue). The upper canines (C1) are long, have a broad base, and curve down and back (recurved). The upper canines exhibit slight sexual dimorphism, with males exhibiting slightly larger canines than females. Both sexes use them in combat by slashing with them. There is a small diastema between the upper canine and the first premolar (P2), which is smaller and more caniniform than the other premolars. Unlike other lemurs, the first two upper molars (M1 and M2) have prominent lingual cingulae, yet do not have a protostyle.

 

Ecology

The ring-tailed lemur is diurnal and semi-terrestrial. It is the most terrestrial of lemur species, spending as much as 33% of its time on the ground. However it is still considerably arboreal, spending 23% of its time in the mid-level canopy, 25% in the upper-level canopy, 6% in the emergent layer and 13% in small bushes. Troop travel is 70% terrestrial.

 

Troop size, home range, and population density vary by region and food availability. Troops typically range in size from 6 to 25, although troops with over 30 individuals have been recorded. The average troop contains 13 to 15 individuals. Home range size varies between 6 and 35 hectares (15 and 86 acres). Troops of the ring-tailed lemur will maintain a territory, but overlap is often high. When encounters occur, they are agonistic, or hostile in nature. A troop will usually occupy the same part of its range for three or four days before moving. When it does move, the average traveling distance is 1 km (0.62 mi). Population density ranges from 100 individuals per 1 km2 (0.39 sq mi) in dry forests to 250–600 individuals per km2 in gallery and secondary forests.

 

The ring-tailed lemur has both native and introduced predators. Native predators include the fossa (Cryptoprocta ferox), the Madagascar harrier-hawk (Polyboroides radiatus), the Madagascar buzzard (Buteo brachypterus) and the Madagascar ground boa (Acrantophis madagascariensis). Introduced predators include the small Indian civet (Viverricula indica), the domestic cat and the domestic dog.

 

Geographic range and habitat

Endemic to southern and southwestern Madagascar, the ring-tailed lemur ranges further into highland areas than other lemurs. It inhabits deciduous forests, dry scrub, montane humid forests, and gallery forests (forests along riverbanks). It strongly favors gallery forests, but such forests have now been cleared from much of Madagascar in order to create pasture for livestock. Depending on location, temperatures within its geographic range can vary from −12 °C (10 °F) at Andringitra Massif to 48 °C (118 °F) in the spiny forests of Beza Mahafaly Special Reserve.

 

This species is found as far east as Tôlanaro, inland towards the mountains of Andringitra on the southeastern plateau, among the spiny forests of the southern part of the island, and north along the west coast to the town of Belo sur Mer. Historically, the northern limits of its range in the west extended to the Morondava River near Morondava. It can still be found in Kirindy Mitea National Park, just south of Morondava, though at very low densities. It does not occur in Kirindy Forest Reserve, north of Morondava. Its distribution throughout the rest of its range is very spotty, with population densities varying widely.

 

The ring-tailed lemur can be easily seen in five national parks in Madagascar: Andohahela National Park, Andringitra National Park, Isalo National Park, Tsimanampetsotse National Park, and Zombitse-Vohibasia National Park. It can also be found in Beza-Mahafaly Special Reserve, Kalambatritra Special Reserve, Pic d'Ivohibe Special Reserve, Amboasary Sud, Berenty Private Reserve, Anja Community Reserve, and marginally at Kirindy Mitea National Park. Unprotected forests that the species has been reported in include Ankoba, Ankodida, Anjatsikolo, Anbatotsilongolongo, Mahazoarivo, Masiabiby, and Mikea.

 

Within the protected regions it is known to inhabit, the ring-tailed lemur is sympatric (shares its range) with as many as 24 species of lemur, covering every living genus except Allocebus, Indri, and Varecia. Historically, the species used to be sympatric with the critically endangered southern black-and-white ruffed lemur (Varecia variegata editorum), which was once found at Andringitra National Park; however, no sightings of the ruffed lemur have been reported in recent years.

In western Madagascar, sympatric ring-tailed lemurs and red-fronted lemurs (Eulemur rufifrons) have been studied together. Little interaction takes place between the two species. While the diets of the two species overlap, they eat in different proportions since the ring-tailed lemur has a more varied diet and spends more time on the ground.

 

Diet

The ring-tailed lemur is an opportunistic omnivore primarily eating fruits and leaves, particularly those of the tamarind tree (Tamarindus indica), known natively as kily. When available, tamarind makes up as much as 50% of the diet, especially during the dry, winter season. The ring-tailed lemur eats from as many as three dozen different plant species, and its diet includes flowers, herbs, bark and sap. It has been observed eating decayed wood, earth, spider webs, insect cocoons, arthropods (spiders, caterpillars, cicadas and grasshoppers) and small vertebrates (birds and chameleons). During the dry season it becomes increasingly opportunistic.

 

Behavior

Social systems

Troops are classified as multi-male groups, with a matriline as the core group. As with most lemurs, females socially dominate males in all circumstances, including feeding priority. Dominance is enforced by lunging, chasing, cuffing, grabbing and biting. Young females do not always inherit their mother's rank and young males leave the troop between three and five years of age. Both sexes have separate dominance hierarchies; females have a distinct hierarchy while male rank is correlated with age. Each troop has one to three central, high-ranking adult males who interact with females more than other group males and lead the troop procession with high-ranking females. Recently transferred males, old males or young adult males that have not yet left their natal group are often lower ranking. Staying at the periphery of the group they tend to be marginalized from group activity.

 

A group of three ring-tailed lemurs rest in the sun, with two sitting upright, facing the sun, with their arms to their sides.

The ring-tailed lemur will sit facing the sun to warm itself in the mornings.

For males, social structure changes can be seasonal. During the six-month period between December and May a few males migrate between groups. Established males transfer on average every 3.5 years, although young males may transfer approximately every 1.4 years. Group fission occurs when groups get too large and resources become scarce.

 

In the mornings the ring-tailed lemur sunbathes to warm itself. It faces the sun sitting in what is frequently described as a "sun-worshipping" posture or lotus position. However, it sits with its legs extended outward, not cross-legged, and will often support itself on nearby branches. Sunning is often a group activity, particularly during the cold mornings. At night, troops will split into sleeping parties huddling closely together to keep warm.

 

Despite being quadrupedal the ring-tailed lemur can rear up and balance on its hind legs, usually for aggressive displays. When threatened the ring-tailed lemur may jump in the air and strike out with its short nails and sharp upper canine teeth in a behaviour termed jump fighting. This is extremely rare outside of the breeding season when tensions are high and competition for mates is intense. Other aggressive behaviours include a threat-stare, used to intimidate or start a fight, and a submissive gesture known as pulled-back lips.

 

Border disputes with rival troops occur occasionally and it is the dominant female's responsibility to defend the troop's home range. Agonistic encounters include staring, lunging approaches and occasional physical aggression, and conclude with troop members retreating toward the center of the home range.

 

Olfactory communication

Olfactory communication is critically important for strepsirrhines like the ring-tailed lemur. Males and females scent mark both vertical and horizontal surfaces at the overlaps in their home ranges using their anogenital scent glands. The ring-tailed lemur will perform a handstand to mark vertical surfaces, grasping the highest point with its feet while it applies its scent. Use of scent marking varies by age, sex and social status. Male lemurs use their antebrachial and brachial glands to demarcate territories and maintain intragroup dominance hierarchies. The thorny spur that overlays the antebrachial gland on each wrist is scraped against tree trunks to create grooves anointed with their scent. This is known as spur-marking.

 

In displays of aggression, males engage in a social display behaviour called stink fighting, which involves impregnating their tails with secretions from the antebrachial and brachial glands and waving the scented tail at male rivals.

 

Ring-tailed lemurs have also been shown to mark using urine. Behaviorally, there is a difference between regular urination, where the tail is slightly raised and a stream of urine is produced, and the urine marking behavior, where the tail is held up in display and only a few drops of urine are used. The urine-marking behavior is typically used by females to mark territory, and has been observed primarily at the edges of the troop's territory and in areas where other troops may frequent. The urine marking behavior also is most frequent during the mating season, and may play a role in reproductive communication between groups.

 

Breeding and reproduction

The ring-tailed lemur is polygynandrous, although the dominant male in the troop typically breeds with more females than other males. Fighting is most common during the breeding season. A receptive female may initiate mating by presenting her backside, lifting her tail and looking at the desired male over her shoulder. Males may inspect the female's genitals to determine receptiveness. Females typically mate within their troop, but may seek outside males.

 

The breeding season runs from mid-April to mid-May. Estrus lasts 4 to 6 hours, and females mate with multiple males during this period. Within a troop, females stagger their receptivity so that each female comes into season on a different day during the breeding season, reducing competition for male attention. Females lactate during the wet season, from December through April, when resources are readily available. Females gestate during the dry season, from May through September, when resources are low. Females give birth during seasons where resources, such as flowers, are in peak. Gestation lasts for about 135 days, and parturition occurs in September or occasionally October. In the wild, one offspring is the norm, although twins may occur. Ring-tailed lemur infants have a birth weight of 70 g (2.5 oz) and are carried ventrally (on the chest) for the first 1 to 2 weeks, then dorsally (on the back).

 

The young lemurs begin to eat solid food after two months and are fully weaned after five months. Sexual maturity is reached between 2.5 and 3 years. Male involvement in infant rearing is limited, although the entire troop, regardless of age or sex, can be seen caring for the young. Alloparenting between troop females has been reported. Kidnapping by females and infanticide by males also occur occasionally. Due to harsh environmental conditions, predation and accidents such as falls, infant mortality can be as high as 50% within the first year and as few as 30% may reach adulthood. The longest-lived ring-tailed lemur in the wild was a female at the Berenty Reserve who lived for 20 years. In the wild, females rarely live past the age of 16, whereas the life expectancy of males is not known due to their social structure. The longest-lived male was reported to be 15 years old. The maximum lifespan reported in captivity was 27 years.

 

Cognitive abilities and tool use

Historically, the studies of learning and cognition in non-human primates have focused on simians (monkeys and apes), while strepsirrhine primates, such as the ring-tailed lemur and its allies, have been overlooked and popularly dismissed as unintelligent. A couple of factors stemming from early experiments have played a role in the development of this assumption. First, the experimental design of older tests may have favored the natural behavior and ecology of simians over that of strepsirrhines, making the experimental tasks inappropriate for lemurs. For example, simians are known for their manipulative play with non-food objects, whereas lemurs are only known to manipulate non-food objects in captivity. This behaviour is usually connected with food association. Also, lemurs are known to displace objects with their nose or mouth more so than with their hands. Therefore, an experiment requiring a lemur to manipulate an object without prior training would favor simians over strepsirrhines. Second, individual ring-tailed lemurs accustomed to living in a troop may not respond well to isolation for laboratory testing. Past studies have reported hysterical behaviour in such scenarios.

 

The notion that lemurs are unintelligent has been perpetuated by the view that the neocortex ratio (as a measure of brain size) indicates intelligence. In fact, primatologist Alison Jolly noted early in her academic career that some lemur species, such as the ring-tailed lemur, have evolved a social complexity similar to that of cercopithecine monkeys, but not the corresponding intelligence. After years of observations of wild ring-tailed lemur populations at the Berenty Reserve in Madagascar and as well as baboons in Africa, she more recently concluded that this highly social lemur species does not demonstrate the equivalent social complexity of cercopithecine monkeys, despite general appearances.

 

Regardless, research has continued to illuminate the complexity of the lemur mind, with emphasis on the cognitive abilities of the ring-tailed lemur. As early as the mid-1970s, studies had demonstrated that they could be trained through operant conditioning using standard schedules of reinforcement. The species has been shown to be capable of learning pattern, brightness, and object discrimination, skills common among vertebrates. The ring-tailed lemur has also been shown to learn a variety of complex tasks often equaling, if not exceeding, the performance of simians.

 

More recently, research at the Duke Lemur Center has shown that the ring-tailed lemur can organize sequences in memory and retrieve ordered sequences without language. The experimental design demonstrated that the lemurs were using internal representation of the sequence to guide their responses and not simply following a trained sequence, where one item in the sequence cues the selection of the next. But this is not the limit of the ring-tailed lemur's reasoning skills. Another study, performed at the Myakka City Lemur Reserve, suggests that this species along with several other closely related lemur species understand simple arithmetic operations.

 

Since tool use is considered to be a key feature of primate intelligence, the apparent lack of this behavior in wild lemurs, as well as the lack of non-food object play, has helped reinforce the perception that lemurs are less intelligent than their simian cousins. However, another study at the Myakka City Lemur Reserve examined the representation of tool functionality in both the ring-tailed lemur and the common brown lemur and discovered that, like monkeys, they used tools with functional properties (e.g., tool orientation or ease of use) instead of tools with nonfunctional features (e.g., color or texture). Although the ring-tailed lemur may not use tools in the wild, it can not only be trained to use a tool, but will preferentially select tools based on their functional qualities. Therefore, the conceptual competence to use a tool may have been present in the common primate ancestor, even though the use of tools may not have appeared until much later.

 

Conservation status

In addition to being listed as endangered in 2014 by the IUCN, the ring-tailed lemur has been listed since 1977 by CITES under Appendix I, which makes trade of wild-caught specimens illegal. Although there are more endangered species of lemur, the ring-tailed lemur is considered a flagship species due to its recognizability. As of 2017, only about 2,000 ring-tailed lemurs are estimated to be left in the wild, making the threat of extinction far more serious for them than previously believed.

 

hree factors threaten ring-tailed lemurs. First and foremost is habitat destruction. Starting nearly 2,000 years ago with the introduction of humans to the island, forests have been cleared to produce pasture and agricultural land. Extraction of hardwoods for fuel and lumber, as well mining and overgrazing, have also taken their toll. Today, it is estimated that 90% of Madagascar's original forest cover has been lost.[61] Rising populations have created even greater demand in the southwest portion of the island for fuel wood, charcoal, and lumber. Fires from the clearing of grasslands, as well as slash-and-burn agriculture destroy forests. Another threat to the species is harvesting either for food (bushmeat), fur clothing or pets. Finally, periodic drought common to southern Madagascar can impact populations already in decline. In 1991 and 1992, for example, a severe drought caused an abnormally high mortality rate among infants and females at the Beza Mahafaly Special Reserve. Two years later, the population had declined by 31% and took nearly four years to start to recover.

 

The ring-tailed lemur resides in several protected areas within its range, each offering varying levels of protection. At the Beza Mahafaly Special Reserve, a holistic approach to in-situ conservation has been taken. Not only does field research and resource management involve international students and local people (including school children), livestock management is used at the peripheral zones of the reserve and ecotourism benefits the local people.

 

Outside of its diminishing habitat and other threats, the ring-tailed lemur reproduces readily and has fared well in captivity. For this reason, along with its popularity, it has become the most populous lemur in zoos worldwide, with more than 2500 in captivity as of 2009. It is also the most common of all captive primates. Ex situ facilities actively involved in the conservation of the ring-tailed lemur include the Duke Lemur Center in Durham, North Carolina, the Lemur Conservation Foundation in Myakka City, Florida, and the Madagascar Fauna Group headquartered at the Saint Louis Zoo. Due to the high success of captive breeding, reintroduction is a possibility if wild populations were to crash. Although experimental releases have met success on St. Catherines Island in Georgia, demonstrating that captive lemurs can readily adapt to their environment and exhibit a full range of natural behaviors, captive release is not currently being considered.

 

Ring-tailed lemur populations can also benefit from drought intervention, due to the availability of watering troughs and introduced fruit trees, as seen at the Berenty Private Reserve in southern Madagascar. However, these interventions are not always seen favorably, since natural population fluctuations are not permitted. The species is thought to have evolved its high fecundity due to its harsh environment.

 

Cultural references

The ring-tailed lemur is known locally in Malagasy as maky (pronounced [ˈmakʲi̥], and spelled maki in French) or hira (pronounced [ˈhirə] or colloquially [ˈir]). Being the most widely recognized endemic primate on the island, it has been selected as the symbol for Madagascar National Parks (formerly known as ANGAP). The Maki brand, which started by selling T-shirts in Madagascar and now sells clothing across the Indian Ocean islands, is named after this lemur due to its popularity, even though the company's logo portrays the face of a sifaka and its name uses the French spelling.

 

The first mention of the ring-tailed lemur in Western literature came in 1625 when English traveller and writer Samuel Purchas described them as being comparable in size to a monkey and having a fox-like long tail with black and white rings. Charles Catton included the species in his 1788 book Animals Drawn from Nature and Engraved in Aqua-tinta, calling it the "Maucauco" and regarding it as a type of monkey.

 

A Ring-tailed lemur named Dotty regularly appeared with Jonny Morris on the BBC television programme Animal Magic.

 

The species was further popularized by the Animal Planet television series Lemur Street, as well as by the character King Julien in the animated Madagascar film and TV franchise.[69] The ring-tailed lemur was also the focus of the 1996 Nature documentary A Lemur's Tale, which was filmed at the Berenty Reserve and followed a troop of lemurs. The troop included a special infant named Sapphire, who was nearly albino, with white fur, bright blue eyes, and the characteristic ringed tail.

 

A Ring-tailed lemur played a role in the 1997 comedy film Fierce Creatures, starring John Cleese, who has a passion for lemurs. Cleese later hosted the 1998 BBC documentary In the Wild: Operation Lemur with John Cleese, which tracked the progress of a reintroduction of black-and-white ruffed lemurs back into the Betampona Reserve in Madagascar. The project had been partly funded by Cleese's donation of the proceeds from the London premier of Fierce Creatures.

On Fear

Our positive capability.

by Mary Ruefle

 

I suppose, as a poet, among my fears can be counted the deep-seated uneasiness that one day it will be revealed that I consecrated my life to an imbecility. Part of what I mean—what I think I mean—by “imbecility” is something intrinsically unnecessary and superfluous and thereby unintentionally cruel. It was a Master who advised that we speak little, better still say nothing, unless we are quite sure that what we wish to say is true, kind, and helpful. But how can a poet, whose role is to speak, adhere to this advice? How can anyone whose role is to facilitate language speak little or say nothing?

 

I don’t know if other poets have this fear, but if they do not, I reason it will only increase the anguish of the outcome if it one day passes into being. To pass into being—now there’s a fear no one ever had. No one ever feared being born, even when all those responsible for the event were fraught with fear for the unborn. And if I may segue to a child at the age of four, I recall watching her beingapproached by a dog that was, well, much larger than the girl herself. The girl’s face was astonishing to watch. It was completely elastic and changed from an expression of wonder and glee: Please come to me doggie and we shall play oh what happiness to be approached by you—to—in less than ten seconds—an expression of sheer terror: Fear! fear! doggie will eat me up and mommie is far away. As the dog slowly crossed the room, in what could not have been more than two minutes, the girl’s face changed expressions so many times I gave up counting. As she oscillated between feeling secure and insecure, it struck me that her face would probably continue to change, albeit at a slower rate, every time she was approached by a dog for the next couple of years, one day coming to rest on that expression that was likely to signify forever after how this human being felt about dogs.

 

But something seemed to be missing from my neat little formula; surely the dog’s face was important, too? This dog was eager and friendly, if a bit clumsy, but what if the next dog took a good-sized chunk out of the child’s face? I asked the poet Tony Hoagland what he thought about fear. He said fear was the ghost of an experience: we fear the recurrence of a pain we once felt, and in this way fear is like a hangover. The memory of our pain is a pain unto itself, and thus feeds our fear like a foyer with mirrors on both sides. And then he quoted Auden: “And ghosts must do again/What gives them pain.” It is interesting to note that this idea—fear’s being the ghost of pain, or imaginary pain—figures in psychological torture by the cia; in fact, their experiments with pain found that imaginary pain was more effective than physical pain—poets, take note—and thus psychological torture more effective than physical torture. Here is an excerpt from their Exploitation Training Manual, written in 1983:

 

The threat of coercion usually weakens or destroys resistance more effectively than coercion itself. The threat to inflict pain, for example, can trigger fears more damaging than the immediate sensation of pain.

 

Although I have never been bitten by a dog, I am scared to death of them, as I am of all living creatures, including myself and my own fragmentation in the long hall of mirrors. James Ward, a British psychologist, broke with religion as a young man in 1872 but found himself a bundle of reflexes over which he had no choice and no control. He said: “I have no dread of God, no fear of the Devil, no fear of man, but my head swims as I write it—I fear myself.” What do I mean by fear? Why I mean that thing that drives you to write—but let us step out of the foyer, and back onto the street, back down the road, and make our approach somewhat more slowly.

 

Sometime after I had already written the pages you are about to sit through, I realized I had been using the wrong word throughout. Dread is a more accurate version of what I am thinking about, and I have Julian of Norwich, a fifteenth-century anchorite, to thank for pointing this out. In her Revelations of Divine Love, the account of a vision she had during an illness in her thirty-first year, she says, “I believe dread can take four forms.” In a nutshell, the first of these forms is what I will describe as the unconscious emotion fear—your very first response to the smell of smoke, the sound of thunder, the sight of flames, the slap. The second form of dread is the anticipatory dread of pain, either physical, emotional, spiritual, or psychological, and that, folks, covers nine-tenths of the world’s surface. The third form of dread is doubt, or despair. And the fourth form of dread is “born of reverence,” the holy dread with which we face that which we love most, or that which loves us the most.

 

Dread. I like it better than the word fear because fear, like the unconscious emotion which is one of its forms, has only the word ear inside of it, telling an animal to listen, while dread has the word read inside of it, telling us to read carefully and find the dead, who are also there. But I have not used the word dread in what follows. I have used the word fear. And fear is an older word—it can be found in Old English, while dread enters the language in Middle English.

 

Neurobiologists have distinguished emotions from feelings, though I am afraid our language has for so long used the two terms as equivalent currency that it is a hopeless task to expect any listener to hear one word and not think of the other. Emotions are hardwired, biological functions of the nervous system such as fear, terror, sexual attraction, and hunger-impelled action (also called “feeding behaviors”). They are each purely physical reactions over which one has no control, and they are common to all animals with a central nervous system. The emotion of fear is what drives all animals away from life-threatening situations, and that is not the kind of fear I have in mind. Feelings, on the other hand, are more complicated and involve cognitive reactions that combine, or can be combined, with emotions, memories, experience, and intelligence. That is the kind of fear I have in mind—the feeling of fear that involves an intelligent, cognitive reaction. Fear that requires self-consciousness.

 

(Don’t be alarmed, scientists are not studying feelings, they are only studying emotions, divorced from cognition, as they travel in recognizable systems throughout the brain and the body.)

 

At this juncture it might be instructive of me to look up at you and say, “Try putting less emotion, and more feeling, into your poems.” The fact that neurobiologists have publicly announced the separation of emotion from feeling should be heartening news to poets everywhere, for it implies that to have feelings is on par with highly sophisticated cognitive systems. Feelings are not subpar. On the other hand, lest we forget, let me repeat: to be more emotional and less cognitive is to be less evolved than the species is able to be. It is to be like a four-year-old child. Feelings seem to represent a place where emotions combine with intelligence and experience to create a highly personal thought process that results in an individual’s worldview.

 

And that is where I want to take up our fear again. I asked a doctor about fear. The doctor said, “The only way to overcome fear is to do what you are trained to do. Fear is overcome by procedure. For example, if I don’t successfully insert an emergency trach—a hole in the throat—someone will die from lack of oxygen. So I mechanically do what I have been trained to do. Someone is there, periodically calling out the oxygen saturation—95, 90, 88, 83, 79—and the lower it gets the more of an emergency it becomes. And the funny thing is, I ask for the count. It is part of the procedure, but I work as if I am not listening—procedural concentration is all.”

 

I asked a pilot about fear. The pilot said, “The only way to overcome fear is to do what you are trained to do. Fear is overcome by procedure. For example, I was flying a test jet alone at thirty thousand feet and there was a leak in my oxygen mask I didn’t know about. I temporarily lost consciousness, and when I came to I was at fifteen thousand feet heading straight for the ground, nose down, completely out of control—and I was still groggy, still fighting for consciousness. Cut the throttle and punch the dive brakes. Cut the throttle and punch the dive brakes. Cut the throttle and punch the dive brakes. Those were the only thoughts I had, and I continued to have them until I leveled out at five thousand feet.” Then the doctor and the pilot, who were in the same room with me, looked at me and said, “So, have you ever had any poetry emergencies?”

 

I was a fool on a fool’s errand. Out of the fear of being a fool, I wanted to tell them that the fear they were trained to overcome was an emotion and not a feeling; after all, these were both life-threatening situations and their reactions were pure instinct, albeit professional ones. But I have professional instincts as well, professional instincts I employ while writing a poem. I was hopelessly confused and felt my sense of self-worth losing altitude; in situations like this I pick up the phone and call my friend, the German philosopher. “Reinhard,” I shouted into the phone, “What do you think about fear?” “Yikes!” he shouted back, “I am afraid of dogs.” At last, a friend. And then he quoted Nietzsche: “The degree of fearfulness is one measure of intelligence.” It was better than I had hoped. Cut the throttle and punch the dive brakes. “Fear is to recognize ourselves.” As far back as I could remember, every minute of my life had been an emergency in which I was paralyzed with fear. Feelings of fear, being at least in part cognitive, and therefore thoughts, often constitute knowledge. For instance, the knowledge that one is going to die. This is a fear one can have while lying in a hammock on a beautiful day. And it can lead to an emergency of feeling that often results in a poem. “Thank you,” I said, before hanging up, and then I heard my friend Reinhard say, “Faulkner, however, said that for a writer, the basest of all things is to be afraid.” My mind quickly came to the conclusion Faulkner was drunk at the time. But perhaps he was thinking about writer’s block, the inability of a writer to do that which is most natural to him: to encounter fear, to face fear; a fear of being alone with fear...

 

Roethke: “Fear was my father, Father Fear./His look drained the stones.”

 

Auden: “Fear gave his watch no look.”

 

Neruda: “When I was a young poet I was full of fear like a real rat in a corner.”

 

And what are we to make of Wordsworth, “Fostered alike by beauty and by fear”?

 

Or Milton’s “equal poise of hope and fear”? Or Blake’s “fearful symmetry”?

 

Which is more inexpressible, the beautiful or the terrifying? Gerard Manley Hopkins, in his last, troubled sonnets, cries out, “O which one? is it each one?” Lorca says,

 

The poet who embarks on the creation of the poem (as I know by experience), begins with the aimless sensation of a hunter about to embark on a night hunt through the remotest of forests. Unaccountable dread stirs in his heart.

 

And Edmond Jabès, in The Book of Questions: “If you bend over your page...and do not suddenly tremble with fear, throw away your pen. Your writing would have little value.”

 

And George Oppen, who said, “Great artists are those, in the end, who do not have a failure of nerve.” Afraid, yes, but there they are, having locked themselves alone in a room with fear. Or as someone else might put it: “Blank pages—shoot-out at the O.K. Corral.”

 

I think it is time to list some concrete fears:

 

fear of death

of illness

of pain

of suffering

of despair

of not understanding

of disturbance or reversal of powers

of being unloved

of the unknown or strange

of destruction

of humiliation

of degradation

of poverty

of hunger

of aging

of unworthiness

of transgression

of punishment

of making a mistake

of loss of dignity

of failure

of oblivion

of outliving the mind

of eating an anchovy

 

These are not simian fears. These are human fears.

 

Barry Lopez, in his study of the Arctic called Arctic Dreams, makes this interesting observation:

 

Eskimos do not maintain this intimacy with nature without paying a certain price. When I have thought about the ways in which they differ from people in my own culture, I have realized that they are more afraid than we are. On a day-to-day basis, they have more fear. Not of being dumped into cold water from an umiak, not a debilitating fear. They are afraid because they accept fully what is violent and tragic in nature. It is a fear tied to their knowledge that sudden, cataclysmic events are as much a part of life, of really living, as are the moments when one pauses to look at something beautiful. A Central Eskimo shaman named Aua, queried by Knud Rasmussen about Eskimo beliefs, answered, “We do not believe. We fear.”

 

Lopez goes on to chastise those who think hunting peoples such as the Eskimos are living in perfect harmony with nature. Nervous awe and apprehension are born out of proximity and attention. The greater the intimacy between these cultures and nature, the greater the tension. The industrial world destroys nature not because it doesn’t love it but because it is not afraid of it. You can in your own minds recall the long Judeo-Christian tradition of fearing God. Or you can perhaps remember having read The Wind in the Willows as a child, or to a child, and encountering that magnificent, odd, and out-of-place chapter entitled “The Piper at the Gates of Dawn” where Mole and Rat go in search of Otter’s lost son and find, on the very edge of dawn, Nature personified in the august presence of a terrifying and benevolent satyr, half man, half animal:

 

“Rat!” he found breath to whisper, shaking. “Are you afraid?”

“Afraid?” murmured the Rat, his eyes shining with unutterable love. “Afraid! Of Him? O, never, never! And yet—and yet—O, Mole, I am afraid!”

Then the two animals, crouching to the earth, bowed their heads and did worship.

 

Fear is the greatest motivator of all time. Conflict born of fear is behind our every action, driving us forward like the cogs of a clock. Fear is desire’s dark dress, its doppelgänger. “Love and dread are brothers,” says Julian of Norwich. As desire is wanting and fear is not-wanting, they become inexorably linked; just as desire can be destructive (the desire for power), fear can be constructive (fear of hurting another); fear of poverty becomes desire for wealth. Collective actions are not exempt from these double powers; consider this succinct and frightening sentence written by John Berger:

 

Everywhere these days more and more people knock their heads against the fact that the future of our planet and what it will offer or deny to its inhabitants, is being decided by boards of men who control more money than all the governments in the world, who never stand for election, and whose sole criterion for every decision they take is whether or not it increases or is prone to increase Profit.

 

But has it ever been any different? Races everywhere have always been at the mercy of collective desire and collective fear, sometimes their own, sometimes others’.

The impulse toward order is born of fear and desire, and the impulse toward chaos is born of the same. The British psychoanalyst D.W. Winnicott believed artists were people driven by the tension between the desire to communicate and the desire to hide.

 

Think of the simplest caricature of a poet, the kind that might be used as a generic figure in a cartoon. Which comes to mind, the forlorn, melancholy, sadly loitering one, suicidal in blue breeches, or the happy eater and drinker, the smeller of roses, the carouser, the gusto-bearing, sun-loving one? In Epicurean atomic theory, “the world functions because from the outset there is a lack of balance.” The French novelist Georges Perec, devoted to mathematical literary forms—he wrote a novel without the letter e in it—speaks of anti-constraints within a system of restraints. He quotes the painter Paul Klee: “Genius is ‘an error in the system.’” (Those of you who have heard lectures on the sonnet may recall that this is often, precisely, the point.) The world functions because of fear, because of the error, the anti-constraint, the anti-perfect, the anti-balance. We stumble. We fall.

 

We fail. And so desire to progress, to become better poets, to eradicate a disease, to become better people, to perfect that which is perpetually imperfect. The biblical “fall” is just such an anti-constraint. The apple was fear. (And remember, fear is knowledge, according to Nietzsche.) The apple set the world in motion by forcing Adam and Eve to migrate out of the Perfect. “Fear is to recognize ourselves,” said the philosopher. One of the fears a young writer has is not being able to write as well as he or she wants to, the fear of not being able to sound like X or Y, a favorite author. But out of fear, hopefully, is born a young writer’s voice: “But now,” says Kierkegaard,

 

to strive to become what one already is: who would take the pains to waste his time on such a task, involving the greatest imaginable degree of resignation?...But for this very reason alone it is a very difficult task...precisely because every human being has a strong natural bent and passion to become something more and different.

 

It is very easy to read those words, and very hard to enact them. Elsewhere Kierkegaard says, “What is education? I should suppose that education was the curriculum one had to run through in order to catch up with oneself.”

There are poets who are resigned to not being able to save the world, who barely have enough time to catch up with themselves and the attendant mystery of their fear and being. I suppose Szymborska was one of them. Here is her compatriot Miłosz describing her:

 

In Szymborska we are divided not into the flesh and a surviving oeuvre...but into “the flesh and a broken whisper”; poetry is no more than a broken whisper, quickly dying laughter.... When it is not the perfection of a work that is important but expression itself, “a broken whisper,” everything becomes, as it has been called, écriture.... To talk about anything, just to talk, becomes an operation in itself, a means of assuaging fear.

 

Much as I am sympathetic to the theory of écriture, I find it—confusing. For why is it meaningless to write with no other function than to assuage fear? Doesn’t that function in itself have a meaning? And why fear the dismantling of language’s semantic function, its being representational of meaning, when that is but one more fear that will drive those in opposition to écriture to write? And certainly this “theory” is no theory at all but a centuries-old practice: “He seemed to be depressed, for he went on writing” reads a twelfth-century Japanese text. Or take Rilke: “I have taken action against fear. I sat up the whole night and wrote; and now I am as thoroughly tired as after a long walk in the fields at Ulsgaard.” Even a bitter poem is a small act of affirmation, and I wonder if we can’t say the same thing about a meaningless poem (if such a thing exists). But Miłosz, who would most certainly disagree, is, to his immortal credit, a knight of faith, and I am but a knight of resignation. Like Kierkegaard: “As far as I am concerned, I am able to describe most excellently the movements of faith; but I cannot make them myself.” The Danish philosopher’s famous essay Fear and Trembling is a rumination on the biblical story of Abraham and Isaac. God asked Abraham to kill Isaac, Abraham’s long-awaited and cherished son, and in the essay Kierkegaard grapples with how an act of murder can become a pleasing, good, and holy act in the eyes of God. It takes faith, a faith Kierkegaard minutely examines and describes, but one that he cannot in the end claim for himself, as devout as he is. He remains what he dubs a knight of resignation, a state that, for all it is worth, is still a state of sin. To be sure, I am “using” Miłosz here for my own purposes. He knows perfectly well he is not a saint. In an interview he has stated—and proved—that he is a man of contradiction. In other words, an ordinary man. But I admire his insistence on an objective reality, his faith in a world and an order that does not exist exclusively in the mind. And he is quite provocative at the end of his essay “The Sand in the Hourglass”:

 

If in our moments of happiness, mastery, ecstasy, we say Yes to heaven and to earth, and all we need is misfortune, sickness, the decline of physical powers to start screaming No, this means that all our judgments can be refuted tomorrow and that it is easy to mistake our life for the world. It is not obvious, however, why weakness—whether of a particular person or of an entire historical era—should be privileged and why the old nihilist from Beckett’s Krapp’s Last Tape should be closer to the truth than he himself was when he was twenty years old.

 

Miłosz closes his essay with an astonishing and succinct remark of Simone Weil’s: “‘I am suffering.’ It is better to say this than to say, ‘This landscape is ugly.’”

 

Fear belongs to man, not to the world. The world feels no fear, at any time, in any place. We are “an unhappy people in a happy world”—Wallace Stevens’s last stance. Feelings of fear—personal, cognitive fear—allow us to feel anguish while lying in a hammock on a beautiful day, allow us to feel as if our life were threatened when the sky is blue and the meadow at peace. Raymond Queneau:

 

The poet is never “inspired, if by inspiration we mean...a function of the poet’s mood, the temperature, the political situation, subjective accidents, or the subconscious.

The poet is never inspired because he is the master of what others assume to be inspiration.... He’s never inspired because he’s always inspired, because the powers of poetry are always at his disposal, obedient to his will, receptive to his guidance.

 

And I want to say the poet is never afraid because he is unceasingly afraid, and therefore cannot become that which he already is, though of course, Mr. Kierkegaard reminds us, he must; you might say fear is the poet’s procedure, that which he has been trained to concentrate on.

 

What an odd thing to say; what a terrible thing to say. Surely someone is saying to himself, “Gee whiz, hasn’t she ever heard of negative capability?” As a matter of fact, I have; those words have become like a sickness unto death for me. As often as I have used them myself, I wish there were a moratorium on them for a decade, so overused are they, so bandied about that they have come to mean just about anything one wants them to, especially a bebop version of Be Here Now, or a diffusive religious awe in which the poet wanders, forever in a stupor. As with most famous sayings, we are given only a fragment of the paragraph from which it comes. “Negative Capability, that is when man is capable of being in uncertainties, Mysteries, doubts, without any irritable reaching after fact reason”: the letter was written by John Keats on a Sunday, late in December of 1817, from Hampstead, and addressed to his brothers George and Tom. The year 1817 is, relatively speaking, quite early in Keats’s career, though only four years before his death; the letter was written before George left for America, before Tom died, before John met Fanny Brawne, before he was sick, and before he had written what are considered his finest poems. One of the things you have to remember about Keats is that his development as a poet was telescoped into an intensely short period of time in which he passed through as many stages as another poet may experience in a life three times as long. Although the letter in its entirety is too long to quote here, you’ll have to trust me when I say that only the last quarter of it puts his definition of negative capability into context. Here is that context:

 

Several things dovetailed in my mind, at once it struck me, what quality went to form a Man of Achievement especially in Literature which Shakespeare possessed so enormously—I mean Negative Capability, that is when man is capable of being in uncertainties, Mysteries, doubts, without any irritable reaching after fact reason—Coleridge, for instance, would let go by a fine isolated verisimilitude caught from the Penetralium of mystery, from being incapable of remaining content with half-knowledge. This pursued through Volumes would perhaps take us no further than this, that with a great poet the sense of Beauty overcomes every other consideration, or rather obliterates all consideration.

 

The passage is a bit like the us Constitution. By that I mean that it may be interpreted to suit the purposes of a great many people who are at odds with one another. For instance, nothing prevents someone from saying that the essential definition means: once depressed, stay depressed. Of the passage relating to Coleridge there is no doubt: all you have to know is that Coleridge was the great intellectual among the Romantics, the great thinker. But an interesting and further complicating key is provided by the phrase “isolated verisimilitude.” Verisimilitude means “having the appearance of a truth; probable,” so that Keats is saying something like this: “Coleridge would pass over a probability that someone else would accept as the truth because Coleridge is not content with appearance or probability.” If we add to this the idea of isolating, which implies distinction or differentiation, we can’t help but think that Keats has searched the penetralium of mystery at least long enough to isolate a probable truth that is, unto him, sufficient. And this is a far cry from the non-isolating attitude that most of us associate with negative capability. Following this, Keats does a remarkable thing—he sums up something he has not even elaborated on. He says, “This pursued through Volumes would perhaps take us no further than this, that with a great poet the sense of Beauty overcomes every other consideration, or rather obliterates all consideration.” What does this mean? For where was there ever any mention of Beauty in the original definition? And do you see how this last bit could be used as a defense by the most archly formal poet or by his worst nemesis? And if I presume to understand negative capability, am I then incapable of it, since it is the capability of being in the presence of an uncertainty without reaching to understand it? And finally, we always intimately connect John Keats with negative capability as if he possessed it himself, as if he were speaking of himself, when he was not thinking or speaking of himself at all but of Shakespeare—and who among us amounts to squat compared to Him—of whom we can be as uncertain as we like without reaching after facts, because there are none? Shakespeare’s reputation as a god is enhanced tenfold by the mysterious circumstances of his being. As is always the case, the unknown raises the stakes and the stature and the flag of the formidable before which we bow and do worship in unaccountable dread. Keats sought to understand much in his life; his poems and letters are full of urgent searching, of the kinds of questions that arise in the minds of passionate youth. He says in another letter:

 

You tell me never to despair—I wish it was as easy for me to observe the saying—truth is I have a horrid Morbidity of Temperament which has shown itself at intervals—it is I have no doubt the greatest Enemy and stumbling block I have to fear—I may even say that it is likely to be the cause of my disappointment.

 

One has only to look at the opening lines of a majority of his poems to see him in a state of uncertainty, mystery, doubt—that is, fear:

 

“When I have fears that I may cease to be”

“Glory and loveliness have Pass’d away”

“My spirit is too weak—mortality”

“O thou whose face hath felt the Winter’s wind”

“In a drear-nighted December”

“Deep in the shady sadness of a vale”

“If by dull rhymes our English must be chain’d”

“O what can ail thee, knight at arms”

“Why did I laugh tonight?”

“My heart aches, and a drowsy numbness pains”

 

The suffering in these poems remains intact; it is neither resolved nor negated. What happens for the most part is, the poems dissolve, finally, into the cream of the physical world. If negative capability works at all, it works in reverse, a kind of negative negative capability—which would make it positive—where very real anxiety and irritability over mystery and doubt enable the poet—no, propel him—into the world of the eye, the pure perceptual habit that checks all cognitive drives, not before they’ve begun but after they’ve begun, and done their damage. In the words of a painter, the abstract expressionist Pat Adams—

 

That marveling rush of wonder at sheer multiplicity and differentiation of stuff when surfaces of heightened materiality, of encrusted and layered imprinting are generated to entangle our attention and delay cognition

 

—until it seems that perpetual fear is a propellant into the innocent, fearless, and vulnerable world of the senses. So that the poet paralyzed with fear lying in a hammock on a beautiful day—unhappy man in a happy world—does not suffer any less when he looks around him; he does not cease to suffer, he only ceases to try to understand.

 

It was the last nostalgia: that he

Should understand. That he might suffer or that

He might die was the innocence of living, if life

Itself was innocent.

 

—From Esthétique du Mal, by Wallace Stevens

 

We do not know the etymology of the word fear. That is, the makers of dictionaries are unsure of it. But there is a good chance that it is related to the word fare in its oldest sense, which is to pass through, to go through, as in, How did you fare at the dentist’s? or Fare-thee-well or, He fared in this life like one whose name was writ in water.

 

Keats died at an age when no one should have to die. I wonder if the young are less afraid of dying, or more afraid of dying, than the old. I am no longer young. I am old enough to understand and know that it is not death I am afraid of, it’s dying. Dying is the act, most often painful, that leads to death, while death itself is as painless as the feeling you had before you were born—no feeling at all, you didn’t care one way or another (feeling is caring one way or another). But what do I know? Blessed Brother André, currently under investigation for sainthood, said, “If we knew the value of suffering, we would ask for it.” Though others can, I cannot fathom that remark, let alone embrace it. Nor am I a Buddhist, one who believes suffering is based on ignorance, and that ignorance can be eradicated; actually, I do believe that suffering is based on ignorance (if the Third Reich had not been ignorant, millions would not have had to perish), but I don’t believe ignorance can be eradicated. Actually, I do believe ignorance can be eradicated, but in the way of a weed—it will only pop up again someplace else. When Brother André asks us to embrace suffering, is he saying, “If we knew the value of ignorance, we would ask for it?” Should we finally and willingly cease to understand? I have often said I would rather wonder than know. Is that a youthful stance, a Keatsian stance? Is that—could it be—negative capability? Should one mature beyond it? I don’t know. Rilke advises the young to “live the questions now,” because the answers can only be revealed in time, the extension of which they do not possess. Much like Keats himself says, in a letter, that certain lessons can only be learned on the touchstone of the heart, that is, through direct experience.

 

What has life taught me? I am much less afraid than I ever was in my youth—of everything. That is a fact. At the same time, I feel more afraid than ever. And the two, I can assure you, are not opposed but inextricably linked. I am more or less the same age Emily Dickinson was when she died. Here is what she thought: “Had we the first intimation of the Definition of Life, the calmest of us would be Lunatics!” The calm lunatic—now that is something to aspire to.

 

The ring-tailed lemur (Lemur catta) is a medium- to larger-sized strepsirrhine (wet-nosed) primate, and the most internationally-recognized lemur species, owing to its long, black-and-white, ringed tail. It belongs to Lemuridae, one of five lemur families, and is the only member of the Lemur genus. Like all lemurs, it is endemic to the island of Madagascar, where it is endangered. Known locally in Malagasy as maky ([makʲ] ⓘ, spelled maki in French) or hira, it ranges from gallery forests to spiny scrub in the southern regions of the island. It is omnivorous, as well as the most adapted to living terrestrially of the extant lemurs.

 

The ring-tailed lemur is highly social, living in groups of up to 30 individuals. It is also a female-dominant species, a commonality among lemurs. To keep warm and reaffirm social bonds, groups will huddle together. Mutual grooming is another vital aspect of lemur socialization (as with all primates), reaffirming social and familial connections, while also helping rid each other of any potential insects. Ring-tailed lemurs are strictly diurnal, being active exclusively during daylight hours. Due to this lifestyle, they also sunbathe; the lemurs can be observed sitting upright on their tails, exposing their soft, white belly fur towards the sun. They will often also have their palms open and eyes gently closed. Like other lemurs, this species relies strongly on their sense of smell, and territorial marking, with scent glands, provides communication signals throughout a group’s home range. The glands are located near the eyes, as well as near the anus. The males perform a unique scent-marking behavior called spur-marking, and will participate in stink fights by dousing their tails with their pheromones and “wafting” it at opponents. Additionally, lemurs of both sexes will scent-mark trees, logs, rocks or other objects by simply rubbing their faces and bodies onto it, not unlike a domestic cat.

 

As one of the most vocal primates, the ring-tailed lemur uses numerous vocalizations, including calling for group cohesion and predator alarm calls. Experiments have shown that the ring-tailed lemur, despite the lack of a large brain (relative to simiiform primates), can organize sequences, understand basic arithmetic operations, and preferentially select tools based on functional qualities.

 

Despite adapting to and breeding easily under captive care (and being the most popular species of lemur in zoos worldwide, with more than 2,000 captive-raised individuals), the wild population of ring-tailed lemur is listed as endangered by the IUCN Red List, due to habitat destruction, local hunting for bushmeat and the exotic pet trade. As of early 2017, the population in the wild is believed to have crashed to as low as 2,000 individuals due to these reasons, making them far more critically endangered. Local Malagasy farmers and logging industries frequently make use of slash and burn deforestation techniques, with smoke being visible on the horizon on most days in Madagascar, in an effort to accommodate livestock and to cultivate larger fields of crops.

 

Etymology

Although the term "lemur" was first intended for slender lorises, it was soon limited to the endemic Malagasy primates, which have been known as "lemurs" ever since. The name derives from the Latin term lemures, which refers to specters or ghosts that were exorcised during the Lemuria festival of ancient Rome. According to Carl Linnaeus's own explanation, the name was selected because of the nocturnal activity and slow movements of the slender loris. Being familiar with the works of Virgil and Ovid and seeing an analogy that fit with his naming scheme, Linnaeus adapted the term "lemur" for these nocturnal primates. However, it has been commonly and falsely assumed that Linnaeus was referring to the ghost-like appearance, reflective eyes, and ghostly cries of lemurs. It has also been speculated that Linnaeus may also have known that some Malagasy people have held legends that lemurs are the souls of their ancestors, but this is unlikely given that the name was selected for slender lorises from India. The species name, catta, refers to the ring-tailed lemur's cat-like appearance. Its purring vocalization is similar to that of the domestic cat.

 

Following Linnaeus's species description, the common name "ring-tailed maucauco" was first penned in 1771 by Welsh naturalist Thomas Pennant, who made note of its characteristic long, banded tail. (The term "maucauco" was a very common term for lemurs at this time.) The now universal English name "ring-tailed lemur" was first used by George Shaw in his illustrated scientific publication covering the Leverian collection, which was published between 1792 and 1796.

 

Evolutionary history

All mammalian fossils from Madagascar come from recent times.[11] Thus, little is known about the evolution of the ring-tailed lemur, let alone the rest of the lemur clade, which comprises the entire endemic primate population of the island. However, chromosomal and molecular evidence suggest that lemurs are more closely related to each other than to other strepsirrhine primates. For this to have happened, it is thought that a very small ancestral population came to Madagascar via a single rafting event between 50 and 80 million years ago. Subsequent evolutionary radiation and speciation has created the diversity of Malagasy lemurs seen today.

 

According to analysis of amino acid sequences, the branching of the family Lemuridae has been dated to 26.1 ±3.3 mya while rRNA sequences of mtDNA place the split at 24.9 ±3.6 mya. The ruffed lemurs are the first genus to split away (most basal) in the family, a view that is further supported by analysis of DNA sequences and karyotypes. Additionally, Molecular data suggests a deep genetic divergence and sister group relationship between the true lemurs (Eulemur) and the other two genera: Lemur and Hapalemur.

 

The ring-tailed lemur is thought to share closer affinities to the bamboo lemurs of the genus Hapalemur than to the other two genera in its family. This has been supported by comparisons in communication, chromosomes, genetics, and several morphological traits, such as scent gland similarities. However, other data concerning immunology and other morphological traits fail to support this close relationship. For example, Hapalemur species have short snouts, while the ring-tailed lemur and the rest of Lemuridae have long snouts. However, differences in the relationship between the orbit (eye socket) and the muzzle suggest that the ring-tailed lemur and the true lemurs evolved their elongated faces independently.

 

The relationship between the ring-tailed lemur and bamboo lemurs is the least understood. Molecular analysis suggests that either the bamboo lemurs diverged from the ring-tailed lemur, making the group monophyletic and supporting the current two-genera taxonomy, or that the ring-tailed lemur is nested in with the bamboo lemurs, requiring Hapalemur simus to be split off into its own genus, Prolemur.

 

The karyotype of the ring-tailed lemur has 56 chromosomes, of which four are metacentric (arms of nearly equal length), four are submetacentric (arms of unequal length), and 46 are acrocentric (the short arm is hardly observable). The X chromosome is metacentric and the Y chromosome is acrocentric.

 

Taxonomic classification

Linnaeus first used the genus name Lemur to describe "Lemur tardigradus" (the red slender loris, now known as Loris tardigradus) in his 1754 catalog of the Museum of King Adolf Frederick. In 1758, his 10th edition of Systema Naturae listed the genus Lemur with three included species, only one of which is still considered to be a lemur while another is no longer considered to be a primate. These species include: Lemur tardigradus, Lemur catta (the ring-tailed lemur), and Lemur volans (the Philippine colugo, now known as Cynocephalus volans). In 1911, Oldfield Thomas made Lemur catta the type species for the genus, despite the term initially being used to describe lorises. On January 10, 1929, the International Commission on Zoological Nomenclature (ICZN) formalized this decision in its publication of Opinion 122.

 

The ring-tailed lemur shares many similarities with ruffed lemurs (genus Varecia) and true lemurs (genus Eulemur), and its skeleton is nearly indistinguishable from that of the true lemurs. Consequently, the three genera were once grouped together in the genus Lemur and more recently are sometimes referred to as subfamily Lemurinae (within family Lemuridae). However, ruffed lemurs were reassigned to the genus Varecia in 1962, and due to similarities between the ring-tailed lemur and the bamboo lemurs, particularly in regards to molecular evidence and scent glands similarities, the true lemurs were moved to the genus Eulemur by Yves Rumpler and Elwyn L. Simons (1988) as well as Colin Groves and Robert H. Eaglen (1988). In 1991, Ian Tattersall and Jeffrey H. Schwartz reviewed the evidence and came to a different conclusion, instead favoring to return the members of Eulemur and Varecia to the genus Lemur. However, this view was not widely accepted and the genus Lemur remained monotypic, containing only the ring-tailed lemur. Because the differences in molecular data are so minute between the ring-tailed lemur and both genera of bamboo lemurs, it has been suggested that all three genera be merged.

 

Because of the difficulty in discerning the relationships within family Lemuridae, not all authorities agree on the taxonomy, although the majority of the primatological community favors the current classification.

In 1996, researchers Steven Goodman and Olivier Langrand suggested that the ring-tailed lemur may demonstrate regional variations, particularly a high mountain population at Andringitra Massif that has a thicker coat, lighter coloration, and variations in its tail rings. In 2001, primatologist Colin Groves concluded that this does not represent a locally occurring subspecies. This decision was later supported by further fieldwork that showed that the differences fell within the normal range of variation for the species. The thicker coat was considered a local adaptation to extreme low temperatures in the region, and the fading of the fur was attributed to increased exposure to solar radiation. Additional genetic studies in 2000 further supported the conclusion that population did not vary significantly from the other ring-tailed lemur populations on the island.

 

Anatomy and physiology

The ring-tailed lemur is a strepsirrhine primate, with a protruding muzzle and a wet nose. Top is the skull.

The ring-tailed lemur is a relatively large lemur. Its average weight is 2.2 kilograms (4.9 lb). Its head–body length ranges between 39 and 46 cm (15 and 18 in), its tail length is 56 and 63 cm (22 and 25 in), and its total length is 95 and 110 cm (37 and 43 in). Other measurements include a hind foot length of 102 and 113 mm (4.0 and 4.4 in), ear length of 40 and 48 mm (1.6 and 1.9 in), and cranium length of 78 and 88 mm (3.1 and 3.5 in).

 

The species has a slender frame and narrow face, fox-like muzzle. The ring-tailed lemur's trademark—a long, bushy tail—is ringed in alternating black and white transverse bands, numbering 12 or 13 white rings and 13 or 14 black rings, and always ending in a black tip. The total number of rings nearly matches the approximate number of caudal vertebrae Its tail is longer than its body and is not prehensile. Instead, it is only used for balance, communication, and group cohesion.

 

The pelage (fur) is so dense that it can clog electric clippers. The ventral (chest) coat and throat are white or cream. The dorsal (back) coat varies from gray to rosy-brown, sometimes with a brown pygal patch around the tail region, where the fur grades to pale gray or grayish brown. The dorsal coloration is slightly darker around the neck and crown. The hair on the throat, cheeks, and ears is white or off-white and also less dense, allowing the dark skin underneath to show through. The muzzle is dark grayish and the nose is black, and the eyes are encompassed by black triangular patches. Facial vibrissae (whiskers) are developed and found above the lips (mystacal), on the cheeks (genal), and on the eyebrow (superciliary). Vibrissae are also found slightly above the wrist on the underside of the forearm. The ears are relatively large compared to other lemurs and are covered in hair, which has only small tufts if any. Although slight pattern variations in the facial region may be seen between individuals, there are no obvious differences between the sexes.

 

Unlike most diurnal primates, but like all strepsirrhine primates, the ring-tailed lemur has a tapetum lucidum, or reflective layer behind the retina of the eye, that enhances night vision. The tapetum is highly visible in this species because the pigmentation of the ocular fundus (back surface of the eye), which is present in—but varies between—all lemurs, is very spotty. The ring-tailed lemur also has a rudimentary foveal depression on the retina. Another shared characteristic with the other strepsirrhine primates is the rhinarium, a moist, naked, glandular nose supported by the upper jaw and protruding beyond the chin. The rhinarium continues down where it divides the upper lip. The upper lip is attached to the premaxilla, preventing the lip from protruding and thus requiring the lemur to lap water rather than using suction.

 

The skin of the ring-tailed lemur is dark gray or black in color, even in places where the fur is white. It is exposed on the nose, palms, soles, eyelids, lips, and genitalia. The skin is smooth, but the leathery texture of the hands and feet facilitate terrestrial movement. The anus, located at the joint of the tail, is covered when the tail is lowered. The area around the anus (circumanal area) and the perineum are covered in fur. In males, the scrotum lacks fur, is covered in small, horny spines, and the two sacs of the scrotum are divided. The penis is nearly cylindrical in shape and is covered in small spines, as well as having two pairs of larger spines on both sides. Males have a relatively small baculum (penis bone) compared to their size. The scrotum, penis, and prepuce are usually coated with a foul-smelling secretion. Females have a thick, elongated clitoris that protrudes from the labia of the vulva. The opening of the urethra is closer to the clitoris than the vagina, forming a "drip tip".

 

Females have two pairs of mammary glands (four nipples), but only one pair is functional. The anterior pair (closest to the head) are very close to the axillae (armpit). Furless scent glands are present on both males and females. Both sexes have small, dark antebrachial (forearm) glands measuring 1 cm long and located on the inner surface of the forearm nearly 25 cm (9.8 in) above the wrist joint. (This trait is shared between the Lemur and Hapalemur genera.) The gland is soft and compressible, bears fine dermal ridges (like fingerprints), and is connected to the palm by a fine, 2 mm–high, hairless strip. However, only the male has a horny spur that overlays this scent gland. The spur develops with age through the accumulation of secretions from an underlying gland that may connect through the skin through as many as a thousand minuscule ducts. The males also have brachial (arm) glands on the axillary surface of their shoulders (near the armpit). The brachial gland is larger than the antebrachial gland, covered in short hair around the periphery, and has a naked crescent-shaped orifice near the center. The gland secretes a foul-smelling, brown, sticky substance. The brachial gland is barely developed if present at all in females. Both sexes also have apocrine and sebaceous glands in their genital or perianal regions, which are covered in fur.

 

Its fingers are slender, padded, mostly lacking webbing, and semi-dexterous with flat, human-like nails. The thumb is both short and widely separated from the other fingers. Despite being set at a right angle to the palm, the thumb is not opposable since the ball of the joint is fixed in place. As with all strepsirrhines, the hand is ectaxonic (the axis passes through the fourth digit) rather than mesaxonic (the axis passing through the third digit) as seen in monkeys and apes. The fourth digit is the longest, and only slightly longer than the second digit. Likewise, the fifth digit is only slightly longer than the second. The palms are long and leathery, and like other primates, they have dermal ridges to improve grip. The feet are semi-digitigrade and more specialized than the hands. The big toe is opposable and is smaller than the big toe of other lemurs, which are more arboreal. The second toe is short, has a small terminal pad, and has a toilet-claw (sometimes referred to as a grooming claw) specialized for personal grooming, specifically to rake through fur that is unreachable by the mouth. The toilet-claw is a trait shared among nearly all living strepsirrhine primates. Unlike other lemurs, the ring-tailed lemur's heel is not covered by fur.

Like other lemurs, the ring-tailed lemur has a claw-like nail (toilet-claw) on its second toe (left) and dermal ridges on its hands to improve its grip (center). Unlike other lemurs, it lacks fur on its heel (right).

Dentition

The front, lower dentition includes a toothcomb (4 incisors and 2 canine teeth), while the first premolars resemble canines.

The ring-tailed lemur has a dentition of

2.1.3.3

2.1.3.3

 × 2 = 36, meaning that on each side of the jaw it has two incisors, one canine tooth, three premolars, and three molar teeth.[3] Its deciduous dentition is

2.1.3

2.1.3

 × 2 = 24. The permanent teeth erupt in the following order: m 1/1 (first molars), i 2/2 (first incisors), i 3/3 (second incisors), C1 (upper canines), m 2/2 (second molars), c1 (lower canines), m 3/3 (third molars), p 4/4 (third premolars), p 3/3 (second premolars), p 2/2 (first premolars).

 

Its lower incisors (i1 and i2) are long, narrow, and finely spaced while pointing almost straight forward in the mouth (procumbent). Together with the incisor-shaped (incisiform) lower canines (c1), which are slightly larger and also procumbent, form a structure called a toothcomb, a trait unique to nearly all strepsirrhine primates. The toothcomb is used during oral grooming, which involves licking and tooth-scraping. It may also be used for grasping small fruits, removing leaves from the stem when eating, and possibly scraping sap and gum from tree bark. The toothcomb is kept clean using a sublingual organ—a thin, flat, fibrous plate that covers a large part of the base of the tongue. The first lower premolar (p2) following the toothcomb is shaped like a canine (caniniform) and occludes the upper canine, essentially filling the role of the incisiform lower canine. There is also a diastema (gap) between the second and third premolars.

 

The upper incisors are small, with the first incisors space widely from each other, yet closely to the second incisors . Both are compressed buccolingually (between the cheek and the tongue). The upper canines (C1) are long, have a broad base, and curve down and back (recurved). The upper canines exhibit slight sexual dimorphism, with males exhibiting slightly larger canines than females. Both sexes use them in combat by slashing with them. There is a small diastema between the upper canine and the first premolar (P2), which is smaller and more caniniform than the other premolars. Unlike other lemurs, the first two upper molars (M1 and M2) have prominent lingual cingulae, yet do not have a protostyle.

 

Ecology

The ring-tailed lemur is diurnal and semi-terrestrial. It is the most terrestrial of lemur species, spending as much as 33% of its time on the ground. However it is still considerably arboreal, spending 23% of its time in the mid-level canopy, 25% in the upper-level canopy, 6% in the emergent layer and 13% in small bushes. Troop travel is 70% terrestrial.

 

Troop size, home range, and population density vary by region and food availability. Troops typically range in size from 6 to 25, although troops with over 30 individuals have been recorded. The average troop contains 13 to 15 individuals. Home range size varies between 6 and 35 hectares (15 and 86 acres). Troops of the ring-tailed lemur will maintain a territory, but overlap is often high. When encounters occur, they are agonistic, or hostile in nature. A troop will usually occupy the same part of its range for three or four days before moving. When it does move, the average traveling distance is 1 km (0.62 mi). Population density ranges from 100 individuals per 1 km2 (0.39 sq mi) in dry forests to 250–600 individuals per km2 in gallery and secondary forests.

 

The ring-tailed lemur has both native and introduced predators. Native predators include the fossa (Cryptoprocta ferox), the Madagascar harrier-hawk (Polyboroides radiatus), the Madagascar buzzard (Buteo brachypterus) and the Madagascar ground boa (Acrantophis madagascariensis). Introduced predators include the small Indian civet (Viverricula indica), the domestic cat and the domestic dog.

 

Geographic range and habitat

Endemic to southern and southwestern Madagascar, the ring-tailed lemur ranges further into highland areas than other lemurs. It inhabits deciduous forests, dry scrub, montane humid forests, and gallery forests (forests along riverbanks). It strongly favors gallery forests, but such forests have now been cleared from much of Madagascar in order to create pasture for livestock. Depending on location, temperatures within its geographic range can vary from −12 °C (10 °F) at Andringitra Massif to 48 °C (118 °F) in the spiny forests of Beza Mahafaly Special Reserve.

 

This species is found as far east as Tôlanaro, inland towards the mountains of Andringitra on the southeastern plateau, among the spiny forests of the southern part of the island, and north along the west coast to the town of Belo sur Mer. Historically, the northern limits of its range in the west extended to the Morondava River near Morondava. It can still be found in Kirindy Mitea National Park, just south of Morondava, though at very low densities. It does not occur in Kirindy Forest Reserve, north of Morondava. Its distribution throughout the rest of its range is very spotty, with population densities varying widely.

 

The ring-tailed lemur can be easily seen in five national parks in Madagascar: Andohahela National Park, Andringitra National Park, Isalo National Park, Tsimanampetsotse National Park, and Zombitse-Vohibasia National Park. It can also be found in Beza-Mahafaly Special Reserve, Kalambatritra Special Reserve, Pic d'Ivohibe Special Reserve, Amboasary Sud, Berenty Private Reserve, Anja Community Reserve, and marginally at Kirindy Mitea National Park. Unprotected forests that the species has been reported in include Ankoba, Ankodida, Anjatsikolo, Anbatotsilongolongo, Mahazoarivo, Masiabiby, and Mikea.

 

Within the protected regions it is known to inhabit, the ring-tailed lemur is sympatric (shares its range) with as many as 24 species of lemur, covering every living genus except Allocebus, Indri, and Varecia. Historically, the species used to be sympatric with the critically endangered southern black-and-white ruffed lemur (Varecia variegata editorum), which was once found at Andringitra National Park; however, no sightings of the ruffed lemur have been reported in recent years.

In western Madagascar, sympatric ring-tailed lemurs and red-fronted lemurs (Eulemur rufifrons) have been studied together. Little interaction takes place between the two species. While the diets of the two species overlap, they eat in different proportions since the ring-tailed lemur has a more varied diet and spends more time on the ground.

 

Diet

The ring-tailed lemur is an opportunistic omnivore primarily eating fruits and leaves, particularly those of the tamarind tree (Tamarindus indica), known natively as kily. When available, tamarind makes up as much as 50% of the diet, especially during the dry, winter season. The ring-tailed lemur eats from as many as three dozen different plant species, and its diet includes flowers, herbs, bark and sap. It has been observed eating decayed wood, earth, spider webs, insect cocoons, arthropods (spiders, caterpillars, cicadas and grasshoppers) and small vertebrates (birds and chameleons). During the dry season it becomes increasingly opportunistic.

 

Behavior

Social systems

Troops are classified as multi-male groups, with a matriline as the core group. As with most lemurs, females socially dominate males in all circumstances, including feeding priority. Dominance is enforced by lunging, chasing, cuffing, grabbing and biting. Young females do not always inherit their mother's rank and young males leave the troop between three and five years of age. Both sexes have separate dominance hierarchies; females have a distinct hierarchy while male rank is correlated with age. Each troop has one to three central, high-ranking adult males who interact with females more than other group males and lead the troop procession with high-ranking females. Recently transferred males, old males or young adult males that have not yet left their natal group are often lower ranking. Staying at the periphery of the group they tend to be marginalized from group activity.

 

A group of three ring-tailed lemurs rest in the sun, with two sitting upright, facing the sun, with their arms to their sides.

The ring-tailed lemur will sit facing the sun to warm itself in the mornings.

For males, social structure changes can be seasonal. During the six-month period between December and May a few males migrate between groups. Established males transfer on average every 3.5 years, although young males may transfer approximately every 1.4 years. Group fission occurs when groups get too large and resources become scarce.

 

In the mornings the ring-tailed lemur sunbathes to warm itself. It faces the sun sitting in what is frequently described as a "sun-worshipping" posture or lotus position. However, it sits with its legs extended outward, not cross-legged, and will often support itself on nearby branches. Sunning is often a group activity, particularly during the cold mornings. At night, troops will split into sleeping parties huddling closely together to keep warm.

 

Despite being quadrupedal the ring-tailed lemur can rear up and balance on its hind legs, usually for aggressive displays. When threatened the ring-tailed lemur may jump in the air and strike out with its short nails and sharp upper canine teeth in a behaviour termed jump fighting. This is extremely rare outside of the breeding season when tensions are high and competition for mates is intense. Other aggressive behaviours include a threat-stare, used to intimidate or start a fight, and a submissive gesture known as pulled-back lips.

 

Border disputes with rival troops occur occasionally and it is the dominant female's responsibility to defend the troop's home range. Agonistic encounters include staring, lunging approaches and occasional physical aggression, and conclude with troop members retreating toward the center of the home range.

 

Olfactory communication

Olfactory communication is critically important for strepsirrhines like the ring-tailed lemur. Males and females scent mark both vertical and horizontal surfaces at the overlaps in their home ranges using their anogenital scent glands. The ring-tailed lemur will perform a handstand to mark vertical surfaces, grasping the highest point with its feet while it applies its scent. Use of scent marking varies by age, sex and social status. Male lemurs use their antebrachial and brachial glands to demarcate territories and maintain intragroup dominance hierarchies. The thorny spur that overlays the antebrachial gland on each wrist is scraped against tree trunks to create grooves anointed with their scent. This is known as spur-marking.

 

In displays of aggression, males engage in a social display behaviour called stink fighting, which involves impregnating their tails with secretions from the antebrachial and brachial glands and waving the scented tail at male rivals.

 

Ring-tailed lemurs have also been shown to mark using urine. Behaviorally, there is a difference between regular urination, where the tail is slightly raised and a stream of urine is produced, and the urine marking behavior, where the tail is held up in display and only a few drops of urine are used. The urine-marking behavior is typically used by females to mark territory, and has been observed primarily at the edges of the troop's territory and in areas where other troops may frequent. The urine marking behavior also is most frequent during the mating season, and may play a role in reproductive communication between groups.

 

Breeding and reproduction

The ring-tailed lemur is polygynandrous, although the dominant male in the troop typically breeds with more females than other males. Fighting is most common during the breeding season. A receptive female may initiate mating by presenting her backside, lifting her tail and looking at the desired male over her shoulder. Males may inspect the female's genitals to determine receptiveness. Females typically mate within their troop, but may seek outside males.

 

The breeding season runs from mid-April to mid-May. Estrus lasts 4 to 6 hours, and females mate with multiple males during this period. Within a troop, females stagger their receptivity so that each female comes into season on a different day during the breeding season, reducing competition for male attention. Females lactate during the wet season, from December through April, when resources are readily available. Females gestate during the dry season, from May through September, when resources are low. Females give birth during seasons where resources, such as flowers, are in peak. Gestation lasts for about 135 days, and parturition occurs in September or occasionally October. In the wild, one offspring is the norm, although twins may occur. Ring-tailed lemur infants have a birth weight of 70 g (2.5 oz) and are carried ventrally (on the chest) for the first 1 to 2 weeks, then dorsally (on the back).

 

The young lemurs begin to eat solid food after two months and are fully weaned after five months. Sexual maturity is reached between 2.5 and 3 years. Male involvement in infant rearing is limited, although the entire troop, regardless of age or sex, can be seen caring for the young. Alloparenting between troop females has been reported. Kidnapping by females and infanticide by males also occur occasionally. Due to harsh environmental conditions, predation and accidents such as falls, infant mortality can be as high as 50% within the first year and as few as 30% may reach adulthood. The longest-lived ring-tailed lemur in the wild was a female at the Berenty Reserve who lived for 20 years. In the wild, females rarely live past the age of 16, whereas the life expectancy of males is not known due to their social structure. The longest-lived male was reported to be 15 years old. The maximum lifespan reported in captivity was 27 years.

 

Cognitive abilities and tool use

Historically, the studies of learning and cognition in non-human primates have focused on simians (monkeys and apes), while strepsirrhine primates, such as the ring-tailed lemur and its allies, have been overlooked and popularly dismissed as unintelligent. A couple of factors stemming from early experiments have played a role in the development of this assumption. First, the experimental design of older tests may have favored the natural behavior and ecology of simians over that of strepsirrhines, making the experimental tasks inappropriate for lemurs. For example, simians are known for their manipulative play with non-food objects, whereas lemurs are only known to manipulate non-food objects in captivity. This behaviour is usually connected with food association. Also, lemurs are known to displace objects with their nose or mouth more so than with their hands. Therefore, an experiment requiring a lemur to manipulate an object without prior training would favor simians over strepsirrhines. Second, individual ring-tailed lemurs accustomed to living in a troop may not respond well to isolation for laboratory testing. Past studies have reported hysterical behaviour in such scenarios.

 

The notion that lemurs are unintelligent has been perpetuated by the view that the neocortex ratio (as a measure of brain size) indicates intelligence. In fact, primatologist Alison Jolly noted early in her academic career that some lemur species, such as the ring-tailed lemur, have evolved a social complexity similar to that of cercopithecine monkeys, but not the corresponding intelligence. After years of observations of wild ring-tailed lemur populations at the Berenty Reserve in Madagascar and as well as baboons in Africa, she more recently concluded that this highly social lemur species does not demonstrate the equivalent social complexity of cercopithecine monkeys, despite general appearances.

 

Regardless, research has continued to illuminate the complexity of the lemur mind, with emphasis on the cognitive abilities of the ring-tailed lemur. As early as the mid-1970s, studies had demonstrated that they could be trained through operant conditioning using standard schedules of reinforcement. The species has been shown to be capable of learning pattern, brightness, and object discrimination, skills common among vertebrates. The ring-tailed lemur has also been shown to learn a variety of complex tasks often equaling, if not exceeding, the performance of simians.

 

More recently, research at the Duke Lemur Center has shown that the ring-tailed lemur can organize sequences in memory and retrieve ordered sequences without language. The experimental design demonstrated that the lemurs were using internal representation of the sequence to guide their responses and not simply following a trained sequence, where one item in the sequence cues the selection of the next. But this is not the limit of the ring-tailed lemur's reasoning skills. Another study, performed at the Myakka City Lemur Reserve, suggests that this species along with several other closely related lemur species understand simple arithmetic operations.

 

Since tool use is considered to be a key feature of primate intelligence, the apparent lack of this behavior in wild lemurs, as well as the lack of non-food object play, has helped reinforce the perception that lemurs are less intelligent than their simian cousins. However, another study at the Myakka City Lemur Reserve examined the representation of tool functionality in both the ring-tailed lemur and the common brown lemur and discovered that, like monkeys, they used tools with functional properties (e.g., tool orientation or ease of use) instead of tools with nonfunctional features (e.g., color or texture). Although the ring-tailed lemur may not use tools in the wild, it can not only be trained to use a tool, but will preferentially select tools based on their functional qualities. Therefore, the conceptual competence to use a tool may have been present in the common primate ancestor, even though the use of tools may not have appeared until much later.

 

Conservation status

In addition to being listed as endangered in 2014 by the IUCN, the ring-tailed lemur has been listed since 1977 by CITES under Appendix I, which makes trade of wild-caught specimens illegal. Although there are more endangered species of lemur, the ring-tailed lemur is considered a flagship species due to its recognizability. As of 2017, only about 2,000 ring-tailed lemurs are estimated to be left in the wild, making the threat of extinction far more serious for them than previously believed.

 

hree factors threaten ring-tailed lemurs. First and foremost is habitat destruction. Starting nearly 2,000 years ago with the introduction of humans to the island, forests have been cleared to produce pasture and agricultural land. Extraction of hardwoods for fuel and lumber, as well mining and overgrazing, have also taken their toll. Today, it is estimated that 90% of Madagascar's original forest cover has been lost.[61] Rising populations have created even greater demand in the southwest portion of the island for fuel wood, charcoal, and lumber. Fires from the clearing of grasslands, as well as slash-and-burn agriculture destroy forests. Another threat to the species is harvesting either for food (bushmeat), fur clothing or pets. Finally, periodic drought common to southern Madagascar can impact populations already in decline. In 1991 and 1992, for example, a severe drought caused an abnormally high mortality rate among infants and females at the Beza Mahafaly Special Reserve. Two years later, the population had declined by 31% and took nearly four years to start to recover.

 

The ring-tailed lemur resides in several protected areas within its range, each offering varying levels of protection. At the Beza Mahafaly Special Reserve, a holistic approach to in-situ conservation has been taken. Not only does field research and resource management involve international students and local people (including school children), livestock management is used at the peripheral zones of the reserve and ecotourism benefits the local people.

 

Outside of its diminishing habitat and other threats, the ring-tailed lemur reproduces readily and has fared well in captivity. For this reason, along with its popularity, it has become the most populous lemur in zoos worldwide, with more than 2500 in captivity as of 2009. It is also the most common of all captive primates. Ex situ facilities actively involved in the conservation of the ring-tailed lemur include the Duke Lemur Center in Durham, North Carolina, the Lemur Conservation Foundation in Myakka City, Florida, and the Madagascar Fauna Group headquartered at the Saint Louis Zoo. Due to the high success of captive breeding, reintroduction is a possibility if wild populations were to crash. Although experimental releases have met success on St. Catherines Island in Georgia, demonstrating that captive lemurs can readily adapt to their environment and exhibit a full range of natural behaviors, captive release is not currently being considered.

 

Ring-tailed lemur populations can also benefit from drought intervention, due to the availability of watering troughs and introduced fruit trees, as seen at the Berenty Private Reserve in southern Madagascar. However, these interventions are not always seen favorably, since natural population fluctuations are not permitted. The species is thought to have evolved its high fecundity due to its harsh environment.

 

Cultural references

The ring-tailed lemur is known locally in Malagasy as maky (pronounced [ˈmakʲi̥], and spelled maki in French) or hira (pronounced [ˈhirə] or colloquially [ˈir]). Being the most widely recognized endemic primate on the island, it has been selected as the symbol for Madagascar National Parks (formerly known as ANGAP). The Maki brand, which started by selling T-shirts in Madagascar and now sells clothing across the Indian Ocean islands, is named after this lemur due to its popularity, even though the company's logo portrays the face of a sifaka and its name uses the French spelling.

 

The first mention of the ring-tailed lemur in Western literature came in 1625 when English traveller and writer Samuel Purchas described them as being comparable in size to a monkey and having a fox-like long tail with black and white rings. Charles Catton included the species in his 1788 book Animals Drawn from Nature and Engraved in Aqua-tinta, calling it the "Maucauco" and regarding it as a type of monkey.

 

A Ring-tailed lemur named Dotty regularly appeared with Jonny Morris on the BBC television programme Animal Magic.

 

The species was further popularized by the Animal Planet television series Lemur Street, as well as by the character King Julien in the animated Madagascar film and TV franchise.[69] The ring-tailed lemur was also the focus of the 1996 Nature documentary A Lemur's Tale, which was filmed at the Berenty Reserve and followed a troop of lemurs. The troop included a special infant named Sapphire, who was nearly albino, with white fur, bright blue eyes, and the characteristic ringed tail.

 

A Ring-tailed lemur played a role in the 1997 comedy film Fierce Creatures, starring John Cleese, who has a passion for lemurs. Cleese later hosted the 1998 BBC documentary In the Wild: Operation Lemur with John Cleese, which tracked the progress of a reintroduction of black-and-white ruffed lemurs back into the Betampona Reserve in Madagascar. The project had been partly funded by Cleese's donation of the proceeds from the London premier of Fierce Creatures.

The majority of research on the effect of mirrors find that looking in a mirror is NOT the same as being looked at by others, or being aware of the gaze of others at all. (Brockner, Hjelle, & Plant, 1985; C. S. Carver, 1975; Charles S. Carver, 1977; Charles S. Carver & Scheier, 1981, 2001; Davies, 1982; Dijksterhuis & Knippenberg, 2000; W. J. Froming, Walker, & Lopyan, 1982; William J. Froming & Carver, 1981; F. X. Gibbons, 1978; Frederick X. Gibbons, Carver, Scheier, & Hormuth, 1979; Frederick X. Gibbons & Gaeddert, 1984; Goukens, Dewitte, & Warlop, 2007; Hormuth, 1982; Macrae, Bodenhausen, & Milne, 1998; Porterfield et al., 1988; M. F. Scheier & Carver, 1980; M. F. Scheier, Carver, & Gibbons, 1979; Michael F. Scheier, 1976; Michael F. Scheier, Carver, & Gibbons, 1981; Spengler, Brass, Kühn, & Schutz-Bosbach, 2010)

 

Indeed some research shows that looking at oneself in a mirror produces exactly the opposite effect as being looked at by others. Being looked at by others encourages people to conform to other's expectations. Looking at a mirror generally encourages people to conform to their own internal standards.

 

There is some research however, that has shown mirrors to increase private self awareness, and at least one paper that has argued that mirrors increase conformance.

 

So bearing in mind that Japanese are largely unaffected by mirrors (Heine et al, 2008), what does this suggest?

 

1) That as in the minority of experiments that show mirror's increase public self awareness, and increasing conformance (Diener & Srull, 1979; Govern & Marsch, 1997; Plant & Ryan, 2006; Wheeler, Morrison, DeMarree, & Petty, 2008; Wiekens & Stapel, 2008; Zanna, 1990) the mirror that they are mentally simulating is "the eyes of the world" (seken no me 世間の目). This is quite likely, and I predict in part true. Mirrors are found to increase both public AND private self awareness, so it seems likely that the mental mirror of the Japanese has both of these effects. The "Interdependent self" (Markus and Kitayama, 1991) of the Japanese is not an absense of self but a self that is both aware of itself, and aware of the impact of others upon itself. The dual influence of the Japanese mental mirror would explain the two aspects of the Japanese self.

 

2) Even if it were the case that the mental mirror of the Japanese is increase private self awareness there is research to suggest that Private self awareness is not a unitary phenomenon (Grant, Franklin, & Langford, 2002; Mittal & Balasubramanian, 1987; Trapnell & Campbell, 1999) but instead

2.1) motivated in different ways by curiosity (leading to self reflection) and a automatic, morbid desire to see the self (rumination)(Trapnell & Campbell, 1999).

2.2) It is also argued that Private self awareness has a motivational and cognitive aspect: on the one hand is an awareness of internal self states and attitudes, and on the other it is the desire to reflect upon the self(Grant, Franklin, & Langford, 2002).

 

It may be that the Japanese are high in the second ruminatory, motivational element of private self-awareness which is not coupled by an increase in self-cognition, as Ma-Kellams recent research tends to suggest.

 

3) The Japanese have a different type of independent self, that sees itself from the positition of a super-addressee, Other or God (known in Japan as Amaterasu the sungoddess) visually, with an aesthetic rather than logical impartiality.

 

Whatever way you cut it however, seeing oneself in a mirror is different from being seen by an audience. In order to unpack this distinction, I claim it will be necessary to reject the argument that the Japanese are "collectivists" in the sense of being socially dependent, since the mirror that the Japanese carry with them also provides a impartial, objective, viewpoint because it is a "riken no ken," a view of self not from that of others, but from a self away from self.

The donkey is a domesticated equine. It derives from the African wild ass, Equus africanus, and may be classified either as a subspecies thereof, Equus africanus asinus, or as a separate species, Equus asinus.  It was domesticated in Africa some 5000–7000 years ago, and has been used mainly as a working animal since that time.

 

There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. While working donkeys are often associated with those living at or below subsistence, small numbers of donkeys or asses are kept for breeding or as pets in developed countries.

 

An adult male donkey is a jack or jackass, an adult female is a jenny or jennet, and an immature donkey of either sex is a foal. Jacks are often mated with female horses (mares) to produce mules; the less common hybrid of a male horse (stallion) and jenny is a hinny.

 

Nomenclature

Traditionally, the scientific name for the donkey is Equus asinus asinus, on the basis of the principle of priority used for scientific names of animals. However, the International Commission on Zoological Nomenclature ruled in 2003 that if the domestic and the wild species are considered subspecies of a common species, the scientific name of the wild species has priority, even when that subspecies was described after the domestic subspecies. This means that the proper scientific name for the donkey is Equus africanus asinus when it is considered a subspecies and Equus asinus when it is considered a species.

 

At one time, the synonym ass was the more common term for the donkey. The first recorded use of donkey was in either 1784 or 1785.  While the word ass has cognates in most other Indo-European languages, donkey is an etymologically obscure word for which no credible cognate has been identified. Hypotheses on its derivation include the following:

 

perhaps from Spanish for its don-like gravity; the donkey was also known as "the King of Spain's trumpeter".

perhaps a diminutive of dun (dull grayish-brown), a typical donkey colour.

perhaps from the name Duncan.

perhaps of imitative origin.

From the 18th century, donkey gradually replaced ass and jenny replaced she-ass, which is now considered archaic. The change may have come about through a tendency to avoid pejorative terms in speech and may be comparable to the substitution in North American English of rooster for cock, or that of rabbit for coney, which was formerly homophonic with cunny (a variation of the word cunt). By the end of the 17th century, changes in pronunciation of both ass and arse had caused them to become homophones in some varieties of English.  Other words used for the ass in English from this time include cuddy in Scotland, neddy in southwestern England and dicky in southeastern England;  moke is documented in the 19th century and may be of Welsh or Romani origin.

 

Burro is a word for donkey in both Spanish and Portuguese. In the United States, it is commonly applied to the feral donkeys that live west of the Rocky Mountains; it may also refer to any small donkey.

 

History

The genus Equus, which includes all extant equines, is believed to have evolved from Dinohippus, via the intermediate form Plesippus. One of the oldest species is Equus simplicidens, described as zebra-like with a donkey-shaped head. The oldest fossil to date is ~3.5 million years old from Idaho, USA. The genus appears to have spread quickly into the Old World, with the similarly aged Equus livenzovensis documented from western Europe and Russia.

 

Molecular phylogenies indicate the most recent common ancestor of all modern equids (members of the genus Equus) lived ~5.6 (3.9–7.8) mya. Direct paleogenomic sequencing of a 700,000-year-old middle Pleistocene horse metapodial bone from Canada implies a more recent 4.07 Myr before present date for the most recent common ancestor (MRCA) within the range of 4.0 to 4.5 Myr BP. The oldest divergencies are the Asian hemiones (subgenus E. (Asinus), including the kulan, onager, and kiang), followed by the African zebras (subgenera E. (Dolichohippus), and E. (Hippotigris)). All other modern forms including the domesticated horse (and many fossil Pliocene and Pleistocene forms) belong to the subgenus E. (Equus) which diverged ~4.8 (3.2–6.5) million years ago.

 

The ancestors of the modern donkey are the Nubian and Somalian subspecies of African wild ass. Remains of domestic donkeys dating to the fourth millennium BC have been found in Ma'adi in Lower Egypt, and it is believed that the domestication of the donkey was accomplished long after the domestication of cattle, sheep and goats in the seventh and eighth millennia BC. Donkeys were probably first domesticated by pastoral people in Nubia, and they supplanted the ox as the chief pack animal of that culture. The domestication of donkeys served to increase the mobility of pastoral cultures, having the advantage over ruminants of not needing time to chew their cud, and were vital in the development of long-distance trade across Egypt. In the Dynasty IV era of Egypt, between 2675 and 2565 BC, wealthy members of society were known to own over 1,000 donkeys, employed in agriculture, as dairy and meat animals and as pack animals. In 2003, the tomb of either King Narmer or King Hor-Aha (two of the first Egyptian pharaohs) was excavated and the skeletons of ten donkeys were found buried in a manner usually used with high ranking humans. These burials show the importance of donkeys to the early Egyptian state and its ruler.

 

By the end of the fourth millennium BC, the donkey had spread to Southwest Asia, and the main breeding centre had shifted to Mesopotamia by 1800 BC. The breeding of large, white riding asses made Damascus famous[citation needed], while Syrian breeders developed at least three other breeds, including one preferred by women for its easy gait. The Muscat or Yemen ass was developed in Arabia. By the second millennium BC, the donkey was brought to Europe, possibly at the same time as viticulture was introduced, as the donkey is associated with the Syrian god of wine, Dionysus. Greeks spread both of these to many of their colonies, including those in what are now Italy, France and Spain; Romans dispersed them throughout their empire.

 

The first donkeys came to the Americas on ships of the Second Voyage of Christopher Columbus, and were landed at Hispaniola in 1495. The first to reach North America may have been two animals taken to Mexico by Juan de Zumárraga, the first bishop of Mexico, who arrived there on 6 December 1528, while the first donkeys to reach what is now the United States may have crossed the Rio Grande with Juan de Oñate in April 1598. From that time on they spread northward, finding use in missions and mines. Donkeys were documented as present in what today is Arizona in 1679. By the Gold Rush years of the 19th century, the burro was the beast of burden of choice of early prospectors in the western United States. With the end of the placer mining boom, many of them escaped or were abandoned, and a feral population established itself.

 

Conservation status

About 41 million donkeys were reported worldwide in 2006. China had the most with 11 million, followed by Pakistan, Ethiopia and Mexico. As of 2017, however, the Chinese population was reported to have dropped to 3 million, with African populations under pressure as well, due to increasing trade and demand for donkey products in China. Some researchers believe the actual number may be somewhat higher since many donkeys go uncounted. The number of breeds and percentage of world population for each of the FAO's world regions was in 2006:

 

In 1997 the number of donkeys in the world was reported to be continuing to grow, as it had steadily done throughout most of history; factors cited as contributing to this were increasing human population, progress in economic development and social stability in some poorer nations, conversion of forests to farm and range land, rising prices of motor vehicles and fuel, and the popularity of donkeys as pets. Since then, the world population of donkeys is reported to be rapidly shrinking, falling from 43.7 million to 43.5 million between 1995 and 2000, and to only 41 million in 2006. The fall in population is pronounced in developed countries; in Europe, the total number of donkeys fell from 3 million in 1944 to just over 1 million in 1994.

 

The Domestic Animal Diversity Information System (DAD-IS) of the FAO listed 189 breeds of ass in June 2011. In 2000 the number of breeds of donkey recorded worldwide was 97, and in 1995 it was 77. The rapid increase is attributed to attention paid to identification and recognition of donkey breeds by the FAO's Animal Genetic Resources project. The rate of recognition of new breeds has been particularly high in some developed countries. In France only one breed, the Baudet du Poitou, was recognised until the early 1990s; by 2005, a further six donkey breeds had official recognition.

 

In developed countries, the welfare of donkeys both at home and abroad has become a concern, and a number of sanctuaries for retired and rescued donkeys have been set up. The largest is The Donkey Sanctuary near Sidmouth, England, which also supports donkey welfare projects in Egypt, Ethiopia, India, Kenya, and Mexico.

 

In 2017, a drop in the number of Chinese donkeys, combined with the fact that they are slow to reproduce, meant that Chinese suppliers began to look to Africa. As a result of the increase in demand, and the price that could be charged, Kenya opened three donkey abattoirs. Concerns for donkeys' well-being, however, have resulted in a number of African countries (including Uganda, Tanzania, Botswana, Niger, Burkina Faso, Mali, and Senegal) banning China from buying their donkey products.

 

In 2019, The Donkey Sanctuary warned that the global donkey population could be reduced by half over the next half decade as the demand for ejiao increases in China.

 

Characteristics

Donkeys vary considerably in size, depending on both breed and environmental conditions, and heights at the withers range from less than 90 centimetres (35 in) to approximately 150 cm (59 in).  Working donkeys in the poorest countries have a life expectancy of 12 to 15 years; in more prosperous countries, they may have a lifespan of 30 to 50 years.

 

Donkeys are adapted to marginal desert lands. Unlike wild and feral horses, wild donkeys in dry areas are solitary and do not form harems. Each adult donkey establishes a home range; breeding over a large area may be dominated by one jack. The loud call or bray of the donkey, which typically lasts for twenty seconds and can be heard for over three kilometres, may help keep in contact with other donkeys over the wide spaces of the desert. Donkeys have large ears, which may pick up more distant sounds, and may help cool the donkey's blood. Donkeys can defend themselves by biting, striking with the front hooves or kicking with the hind legs. Their vocalization, called a bray, is often represented in English as "hee haw".

 

Cross on back

Most donkeys have dorsal and shoulder stripes, primitive markings which form a distinctive cross pattern on their backs.

 

Breeding

A jenny is normally pregnant for about 12 months, though the gestation period varies from 11 to 14 months, and usually gives birth to a single foal. Births of twins are rare, though less so than in horses. About 1.7 percent of donkey pregnancies result in twins; both foals survive in about 14 percent of those. In general jennies have a conception rate that is lower than that of horses (i.e., less than the 60–65% rate for mares).

 

Although jennies come into heat within 9 or 10 days of giving birth, their fertility remains low, and it is likely the reproductive tract has not returned to normal. Thus it is usual to wait one or two further oestrous cycles before rebreeding, unlike the practice with mares. Jennies are usually very protective of their foals, and some will not come into estrus while they have a foal at side. The time lapse involved in rebreeding, and the length of a jenny's gestation, means that a jenny will have fewer than one foal per year. Because of this and the longer gestation period, donkey breeders do not expect to obtain a foal every year, as horse breeders often do, but may plan for three foals in four years.

 

Donkeys can interbreed with other members of the family Equidae, and are commonly interbred with horses. The hybrid between a jack and a mare is a mule, valued as a working and riding animal in many countries. Some large donkey breeds such as the Asino di Martina Franca, the Baudet du Poitou and the Mammoth Jack are raised only for mule production. The hybrid between a stallion and a jenny is a hinny, and is less common. Like other inter-species hybrids, mules and hinnies are usually sterile. Donkeys can also breed with zebras, in which case the offspring is called a zonkey (among other names).

 

Behaviour

Donkeys have a notorious reputation for stubbornness, but this has been attributed to a much stronger sense of self-preservation than exhibited by horses. Likely based on a stronger prey instinct and a weaker connection with humans, it is considerably more difficult to force or frighten a donkey into doing something it perceives to be dangerous for whatever reason. Once a person has earned their confidence they can be willing and companionable partners and very dependable in work.

 

Although formal studies of their behaviour and cognition are rather limited, donkeys appear to be quite intelligent, cautious, friendly, playful, and eager to learn.

 

The donkey has been used as a working animal for at least 5000 years. Of the more than 40 million donkeys in the world, about 96% are in underdeveloped countries, where they are used principally as pack animals or for draught work in transport or agriculture. After human labour, the donkey is the cheapest form of agricultural power. They may also be ridden, or used for threshing, raising water, milling and other work. Some cultures that prohibit women from working with oxen in agriculture do not extend this taboo to donkeys.

 

In developed countries where their use as beasts of burden has disappeared, donkeys are used to sire mules, to guard sheep, for donkey rides for children or tourists, and as pets. Donkeys may be pastured or stabled with horses and ponies, and are thought to have a calming effect on nervous horses. If a donkey is introduced to a mare and foal, the foal may turn to the donkey for support after it has been weaned from its mother.

 

A few donkeys are milked or raised for meat. Approximately 3.5 million donkeys and mules are slaughtered each year for meat worldwide. In Italy, which has the highest consumption of equine meat in Europe and where donkey meat is the main ingredient of several regional dishes, about 1,000 donkeys were slaughtered in 2010, yielding approximately 100 tonnes (98 long tons; 110 short tons) of meat. Asses' milk may command good prices: the average price in Italy in 2009 was €15 per litre, and a price of €6 per 100 ml was reported from Croatia in 2008; it is used for soaps and cosmetics as well as dietary purposes. The niche markets for both milk and meat are expanding. In the past, donkey skin was used in the production of parchment. In 2017, the UK based charity The Donkey Sanctuary estimated that 1.8 million skins were traded every year, but the demand could be as high as 10 million.

 

In China, donkey meat is considered a delicacy with some restaurants specializing in such dishes, and Guo Li Zhuang restaurants offer the genitals of donkeys in dishes. Donkey-hide gelatin is produced by soaking and stewing the hide to make a traditional Chinese medicine product. Ejiao, the gelatine produced by boiling donkey skins, can sell for up to $388 per kilogram, at October 2017 prices.

 

In warfare

During World War I John Simpson Kirkpatrick, a British stretcher bearer serving with the Australian and New Zealand Army Corps, and Richard Alexander "Dick" Henderson of the New Zealand Medical Corps used donkeys to rescue wounded soldiers from the battlefield at Gallipoli.

 

According to British food writer Matthew Fort, donkeys were used in the Italian Army. The Mountain Fusiliers each had a donkey to carry their gear, and in extreme circumstances the animal could be eaten.

 

Donkeys have also been used to carry explosives in conflicts that include the war in Afghanistan and others.

 

Care

Donkey hooves are more elastic than those of horses, and do not naturally wear down as fast. Regular clipping may be required; neglect can lead to permanent damage. Working donkeys may need to be shod. Donkey shoes are similar to horseshoes, but usually smaller and without toe-clips.

 

Nutrition

In their native arid and semi-arid climates, donkeys spend more than half of each day foraging and feeding, often on poor quality scrub. The donkey has a tough digestive system in which roughage is efficiently broken down by hind gut fermentation, microbial action in the caecum and large intestine. While there is no marked structural difference between the gastro-intestinal tract of a donkey and that of a horse, the digestion of the donkey is more efficient. It needs less food than a horse or pony of comparable height and weight, approximately 1.5 percent of body weight per day in dry matter, compared to the 2–2.5 percent consumption rate possible for a horse. Donkeys are also less prone to colic. The reasons for this difference are not fully understood; the donkey may have different intestinal flora to the horse, or a longer gut retention time.

 

Donkeys obtain most of their energy from structural carbohydrates. Some suggest that a donkey needs to be fed only straw (preferably barley straw), supplemented with controlled grazing in the summer or hay in the winter, to get all the energy, protein, fat and vitamins it requires; others recommend some grain to be fed, particularly to working animals, and others advise against feeding straw. They do best when allowed to consume small amounts of food over long periods. They can meet their nutritional needs on 6 to 7 hours of grazing per day on average dryland pasture that is not stressed by drought. If they are worked long hours or do not have access to pasture, they require hay or a similar dried forage, with no more than a 1:4 ratio of legumes to grass. They also require salt and mineral supplements, and access to clean, fresh water. In temperate climates the forage available is often too abundant and too rich; over-feeding may cause weight gain and obesity, and lead to metabolic disorders such as founder (laminitis) and hyperlipaemia, or to gastric ulcers.

 

Throughout the world, working donkeys are associated with the very poor, with those living at or below subsistence level. Few receive adequate food, and in general donkeys throughout the Third World are under-nourished and over-worked.

 

Feral populations

In some areas domestic donkeys have returned to the wild and established feral populations such as those of the burro of North America and the Asinara donkey of Sardinia, Italy, both of which have protected status. Feral donkeys can also cause problems, notably in environments that have evolved free of any form of equid, such as Hawaii. In Australia, where there may be 5 million feral donkeys, they are regarded as an invasive pest and have a serious impact on the environment. They may compete with livestock and native animals for resources, spread weeds and diseases, foul or damage watering holes and cause erosion.

 

Donkey hybrids

The earliest documented donkey hybrid was the kunga, which was used as a draft animal in the Syrian and Mesopotamian kingdoms of the second half of the 3rd millennium BCE. A cross between a captive male Syrian wild ass and a female domesticated donkey (jenny), they represent the earliest known example of human-directed animal hybridization. They were produced at a breeding center at Nagar (modern Tell Brak) and were sold or given as gifts throughout the region, where they became significant status symbols, pulling battle wagons and the chariots of kings, and also being sacrificed to bury with high-status people. They fell out of favor following the introduction of the domestic horse and its donkey hybrid, the mule, into the region at the end of the 3rd millennium BCE.

 

A male donkey (jack) crossed with a female horse produces a mule, while a male horse crossed with a jenny produces a hinny. Horse-donkey hybrids are almost always sterile because of a failure of their developing gametes to complete meiosis. The lower progesterone production of the jenny may also lead to early embryonic loss. In addition, there are reasons not directly related to reproductive biology. Due to different mating behavior, jacks are often more willing to cover mares than stallions are to breed jennies. Further, mares are usually larger than jennies and thus have more room for the ensuing foal to grow in the womb, resulting in a larger animal at birth. It is commonly believed that mules are more easily handled and also physically stronger than hinnies, making them more desirable for breeders to produce.

 

The offspring of a zebra-donkey cross is called a zonkey, zebroid, zebrass, or zedonk; zebra mule is an older term, but still used in some regions today. The foregoing terms generally refer to hybrids produced by breeding a male zebra to a female donkey. Zebra hinny, zebret and zebrinny all refer to the cross of a female zebra with a male donkey. Zebrinnies are rarer than zedonkies because female zebras in captivity are most valuable when used to produce full-blooded zebras. There are not enough female zebras breeding in captivity to spare them for hybridizing; there is no such limitation on the number of female donkeys breeding.

Artist Statement: 'Do What Thou Wilt' is the title of this show because that's what we Humans do: whatever we will. Humanity evolved its cognition, self-awareness, language, innovation, etc. because it allowed us to survive the harshness of the relentless onslaught of nature and the universe. It allowed us to have a minute amount of control of our surroundings so we could exist for yet another generation. After awhile, after our basic needs were met, our will carried us in many different, more contemplative directions. Yet the more we learned and thought we achieved, the more we realized the full breadth of nature, the sheer precipitous sovereignty of the universe, and the infinitesimal part we play in it. Like ants trying to hold up their hill colony in the inescapable and seemingly obstinate wind and rain. In the end, everything washes into the sea; no matter if that sea is the deep blue waters of the ocean or the dust floating in blackness of interstellar space. Although during that flow, we swim in that river of time, doing what we will. As a consequence, at times we think that we are odds with nature and the universe, that we must rampage against it, control it and tame it, or be another victim of its ceaseless entropy. Of course, and quite paradoxically, nature and the universe is doing the same thing we are: bestowing its will. Nevertheless, the fundamental difference is that we are aware of our will, we have volition.

This is the self-fulfilling fulfilling prophecy.

Many assumptions about the nature of birds and their behaviour are completely wrong when applied to Australian birds.

Gisela Kaplan was a professor of sociology when a magpie nestling she was hand-raising bonded closely with her, followed her about and learned to speak.

Her curiosity about birds became so strong she switched careers to become a field biologist and animal behaviourist.

Based in Armidale NSW, Gisela has conducted extensive research into avian behaviour. Her second PhD was a study of the songs of Australian magpies.

 

Gisela's many books on Australian native birds have changed the way these creatures are understood.

 

Along with her teaching, writing and research in ornithology, Gisela has been a wildlife carer for 25 years, raising countless birds of all ages.\

JURY DISTINCTION FOR CATEGORY 3. LOCATIONS AND INSTRUMENTS

Copyright CC-BY-NC-ND: Francesca Angiolani-Larrea

 

Lizards can prove very useful in helping us better understand which factors influence learning, an adaptive ability ubiquitous across the animal kingdom. Our team at the Division of Behavioural Ecology at the University of Bern is studying how sociality and ecology influence different cognitive abilities. This includes the role of gravity in the spatial learning of Tokay geckos, an arboreal and nocturnal lizard native to Asia with excellent night vision, colour vision similar to humans and the ability to perceive UV.

In our experiment, a gecko has to learn the location of food in a maze placed either vertically or horizontally. We are also studying whether females, males and juveniles learn differently under these conditions. This image shows a lizard in a single open maze positioned vertically.

 

Comment of the jury │ The very effective symmetric framing reveals at once what is going on while adeptly leading our gaze onto the main subject of the experiment and the story about to unfold. One cannot but wonder which decision the animal is about to take – and with what consequence.

Les lézards sont très utiles pour nous aider à mieux comprendre les facteurs qui influencent l’apprentissage, une capacité d’adaptation omniprésente dans le règne animal. Notre groupe de la Division d’écologie comportementale de l’Université de Berne étudie comment la socialité et l’écologie influencent différentes capacités cognitives. Nous analysons notamment comment la gravité intervient dans l’apprentissage spatial des geckos Tokay, un lézard arboricole et nocturne originaire d’Asie.

Dans notre expérience, un gecko doit apprendre l’emplacement de la nourriture dans un labyrinthe placé verticalement ou horizontalement. Nous étudions également si les femelles, les mâles et les juvéniles apprennent différemment dans ces conditions. Dans cette image, un lézard se trouve dans un labyrinthe ouvert placé verticalement.

 

Commentaire du jury │ Le cadrage symétrique est efficace pour expliciter la situation tout en conduisant habilement notre regard sur le sujet principal de l’expérience. L’image nous plonge instantanément au cœur de l’histoire sur le point de se dérouler: quelle décision l’animal va-t-il prendre, et avec quelle conséquence?

Eidechsen sind sehr nützlich, wenn wir verstehen wollen, welche Faktoren das Lernen beeinflussen – eine im Tierreich allgegenwärtige Anpassungsfähigkeit. Unsere Gruppe an der Abteilung für Verhaltensökologie der Universität Bern untersucht, wie Sozialität und Ökologie verschiedene kognitive Fähigkeiten beeinflussen. Wir analysieren unter anderem, welche Rolle die Schwerkraft beim räumlichen Lernen eines Tokeh-Geckos spielt, einer in Asien beheimateten baumbewohnenden Echse.

In unserem Experiment muss ein Gecko in einem vertikal oder horizontal platzierten Labyrinth lernen, wo sich das Futter befindet. Wir untersuchen auch, ob Weibchen, Männchen und Jungtiere unter diesen Bedingungen unterschiedlich lernen. In diesem Bild befindet sich eine Eidechse in einem vertikal angelegten offenen Labyrinth.

   

Kommentar der Jury │ Mit dem symmetrischen Bildausschnitt gelingt es effektiv, die Situation zu erklären und gleichzeitig den Blick geschickt auf das Hauptobjekt des Experiments zu lenken. Wir stehen sofort mitten im Geschehen: Welche Entscheidung wird das Tier treffen und mit welchen Folgen?

PROCRUSTES IN SITU

 

PROCRUSTES

A full view both of PROCRUSTES and of the four panels behind. Below is a transcription of the full text of the Blue Triangle"

 

"We live in an age of miracles...August 6th, 1945. Born in a searing flash of light, god himself signed his magnificent demise with the most enormous phallic plume the world had ever seen. Terminus.... Fifty years have passed since the death of god...fifty years of the most miraculous discoveries, inventions and accomplishments—and fifty years of denial and deceit. We live in an age of miracles and refuse to accept the authorship of, hence responsibility for, the miracles themselves. We persist in denying our resplendency and responsibilities within the concept of a new age—a new age with a new concept of time, finite and creative. An Age of Miracles. Thousands upon thousands of men, women and children were consumed in this cataclysmic change of metaphors. God, like an ancient ruler incarnate, adorned his death with innocents, and their blood colors this new age. How old he was! As old as human fear. And though fear still holds us enthralled, we are no longer free to worship it. God is dead and, with him, men in His image. Patriarchy's grave lies in the blood and rubble of Hiroshima, beneath a poisoned cock of smoke. Is it possible that human evolution is gender actuated? Though all genders participate in linear development, environmental and in-species conditions select one gender innately qualified to compete successfully for survival. Meaning that the circumstances of exterior actuality create the internal reality for human evolution and communication—. (It is interesting that the word "gender" refers mainly to language and its syntactic relationships: masculine, feminine, neuter.) One gender has always dominated and, for reasons of mutual survival, the correlative genders, in symbiotic relationship, have supported and reflected the sense of reality, sustaining its primacy. Reality is that state which functions best and if actual conditions alter so, too, must comprehensive reality. Until August 6th, 1945, the actual conditions of environment demanded a masculine gendered reality. This is no longer so.... In a searing flash of light with its accompanying phallic signature, the cognitional symbiosis was altered completely: In a split-second shattering of the Actual, gendered reality shifted the masculine Alpha to Omega. "Mankind" became the human experiment's first gendered epoch. Delivered and signed, He presented the human corporation His final solution—total annihilation...magnificent simplicity. Humanity has been in a crisis of reality for fifty years—and a gendered struggle for dominance. Our cognizance has been presented two alternatives: the inevitable conclusion of masculine dominance within the concept of infinite time or the deposition of masculine reality and the acceptance of Time Finite within the reality construct of an alternate gender. Meaning...if humankind does not shift its metaphorical identity from masculine entelechy it will destroy itself. By his apotheosis will His prophecies be fulfilled. Armageddon. Life-everlasting—with no one to prove Him wrong. There is no real purpose in deconstruction. Mankind's epoch ended on the 6th of August 1945. We are engaged in defining a new age, an age free of the metaphors of dominance and fear—killing and hate. An age without god no matter what guise his bearded face. There is no need to correct the dead. All genders participated in symbiotic relationship. It is over. The hierarchy must change.... A new symbiosis must prevail. The gendered tribal role of provider and protector is without grace. It can no longer provoke obeisance and obsecration by virtue of birthright. We live in a new epoch of ungendered creativity—an Age of Miracles from which will be engendered a new entelechy. From time immemorial, reality has evolved in a constantly threatening environment relying totally on the masculine's ability to compete and provide within the actualities for survival: Man against elements, man against animal and man against man. From one against one to group against group to nation against nation and finally, on 8/6/45, man against life itself. Within the geometric inevitability of his evolving entelechy, mankind will conclude itself. Generation upon generation, century upon century, millennium upon millennium, this gendered primacy for survival has established a density of reality nearly impenetrable in its compaction of metaphor and myth. In a flash of light, humanity was plunged into a hiatus of astonishment, depression and exhilaration. In the face of universal suicide through the symbiotic reality of masculine entelechy, humanity has been forced to question the continuation of gendered supremacy. This fifty-year hiatus has been defined by a choice between revolutionary chaos or an ordered planetary annihilation through gendered apotheosis. Survival has stimulated cognition and revolution: that which would destroy us must be deposed—. The revolution is gendered, the outcome unknown. The symbiotic relationship between masculine, neuter and feminine genders has undergone a violent wrenching of cognitional reality. The past is undergoing a process of deconstruction with history rewritten to include rather than suppress feminine accomplishments and contributions. The neuter genders have positioned themselves viably within the hierarchy of revolutionary change. Under attack, the masculine has become schizophrenic and paranoiac in the realization that the only way to regain control is to subvert the appearance of evolutionary reality. We live in a time of chaos with the masculine and feminine obsessed with re-creating and reprising the past and the gendered neuter demanding viability within the symbiotic Now. We are at war with the god of our fathers. If the human experiment is to continue, He must be eliminated from the symbiotic equation, the past defined and this new epoch created in gender parity. Let the masculine have the past with its gods and redundant birthrights—. For this he must forsake intellectual apotheosis and enter into cognizant reality in full and equal partnership within the gendered Whole. The triarchy of masculine gendered reality continues to dominate this fifty year hiatus. Though humanity knows there has occurred vital and essential change at the very core of cognizance, war, religion and commerce continue patriarchal control of cognitional entelechy. This triarchy, with its fabric of mores and metaphors, has maintained symbiotic absolutism throughout epochal time with entrenchment so profound as to seem insuperable. Radical feminism, however, has made deep fissures and the traditional symbiosis has begun to break down. An inversion has also begun to alter the triumvirate itself. An epochal change has occurred. A new reality is being born. Since 8/6/45, humanity has existed within the solipsistic freedom of the suicide's choice to live or die. In Time-Finite, a new symbiosis is being formed, man-kind displaced, the death of gods. Humanity is on the edge. Either a new entelechy will be provoked or the Experiment will end. As we struggle to shed our epochal skin, split the protective and procrustean chrysalis, jettison the propulsive force whose prolonged embrace would destroy us, it is incumbent to look out over the broad landscape of masculine gendered reality. Feminine infusion within these past fifty years gives some perspective to those areas within masculine orientation willing to adjust to symbiotic evolution—and—those areas which have hardened and opacified their omnific control. Religion is, of course, the most obdurate and lies at the core of masculine entelechy. When man created God in order to reify himself in His image, he perverted the natural evolution of his gendered potential. By establishing this symbiotic inversion between himself and his idea of himself, a schism occurred within gendered masculine entelechy...a stunting and stultification. Of the three genders, the masculine seems pre-fixed and immutable—redundant and preponderant.... A blind actor on an unlighted stage. Isolated and solipsistic. Age-old deceits and perversions are increasingly apparent within the triarchy: war and commerce prosper without benignancy in mechanical expectation while religion utilizes both in its increasingly malignant hypocrisy of divisiveness and hate. This triarchy, once the viable center of gendered symbiosis, has become the Procrustes of myth foretold. Art and science, once engaged in symbiotic union within masculine entelechy, now exist as separate identities outside the masculine sphere of domination—and, because they lie outside, are suspect and threatening: Art no longer serves as meretricious pimp of patriarchal supremacy, nor science directed toward apotheosis. August 6th, 1945, shattered the ancient symbiosis finally and forever by actualizing choice: life or death—nascency or apotheosis. Masculine entelechy, as manifest reality, is disintegrating leaving only its hardcore triarchy to command obeisance: religious, military and commercial fundamentalism. Dominance is sustained by fear, threat and purchase. This final procrustean embrace must be broken. By universal recognition of 8/6/45 as the Omega and Alpha in symbiotic gendered evolution, how magnificent would be our release from redundancy. The actual truths of science and the real truths of art would once again be engaged in symbiotic viability rather than as threats and chattels of a dying entelechy. Science and art—neuters in gendered cognition—are its linchpins. Neither masculine nor feminine, they are the purveyors of truth. Throughout the epoch of Masculine entelechy, the triarchy achieved magnificence during its peaks of symbiotic benignancy: masculine, feminine and neuter in functioning cognitional harmony. Under masculine solipsistic dominance these high points have been minimal, fragile and transcendent. Procrustes slumbered. Like a railroad track, Art and Science in binary relativity have given testimony to gendered evolution; by their evidence do we see the successes and failures of the human experiment. Humanity at its most syntonic evolves in gendered parallelism without distortion or hegemony. As masculine entelechy is personified by the triarchy of Religion, War and Commerce, the feminine, through symbiotic allegiance, has been identified as distaff, mother and chattel. Species survival has, until 8/6/45, flourished within this symbiosis and, through the birth and death, birth and death patterned repeat of masculine gendered entelechy, Time seemed infinite. As long as the binary parallelism existing between masculine and feminine continued in solipsistic linearity, masculine dominance would prevail. This blind assumption did not reckon with neuter volatility within the symbiotic mix. As male and female neutrality lies between male and female sexuality so, too, does the neutrality of Science and Art lie between masculine and feminine genders. As Art and Science reflect and mimic each other's achievements with prophetic results, so, too, do the gendered entelechies of masculine and feminine reflect and mimic each other within a meliorating evolution through linear time. As Art foretold the eventuation of Science, so has the feminine reflected and defined the masculine. His death was in his birth. By actualizing feminine entelechy, the masculine evolved a solipsistic syntax for control within the gendered symbiosis while developing the mechanics and methods for survival in a hostile environment. By force and mimicry, the masculine established dominance: Feminine Spirit was actualized into dogmatic religion which has served to constrain feminine power and establish a perverted masculine surrogacy over birth and creation. Since 8/6/45 there has been a struggle to re-create and reconstitute human entelechy in an environment no longer threatening from without but rather from within. In an aversion to masculine apotheosis, the feminine is asserting itself to continue species evolution through finite time. Born in fear and controlled by fear, the landscape of human consciousness continues to be constricted by masculine solipsistry: chronic religious wars and conflicts, territorial greed, pretentious contact sports, incessant and unremitting advertising...the triarchy persists in postured exaggeration. As the struggle evolves and a new epoch is born, the neuter has attained unaccustomed freedom. Employed by the masculine for his evolving entelechy, the aborted apotheosis and abrupt shift in concepts of time from infinite to finite has unleashed a force no longer indentured. Art, being by nature prophetic, has existed within a kind of free-floating state for twice the time of Science. (It is interesting, however, that since 8/6/45 the triarchal head of Commerce has, with some success, managed to retain its servitude.) It is the Science of technology that has created this Age of Miracles. It is as though by denying (or postponing) Science its role as executioner of apotheosis it has, through technological apology, created an explosion of dazzling brilliance. Unacknowledged by a dead religion still searching for Lazarus and chronically threatened by neutered truth, the miracles of technology also challenge War's egocentricity and gender aggrandizement. War has increasingly become neuter-oriented much in the same vein as commerce—through feminine transfusion. From the Korean War, which occurred at the beginning of finite time, to the Persian Gulf War, which took place forty years later, War was transformed from a reaffirmation of masculine values and authenticity to an exposition of technological astonishments: neutered and ascendant. Denied apotheosis, Masculine entelechy is being absorbed into a neutered symbiosis of parellelism. The end of history? The question smacks of masculine solipsistry. We are within the nascency of a new age, a new concept of time, a new symbiotic entelechy. We must ask new questions—. A meliorating evolution is in process and humanity is in hiatal crisis between life and death and life. Masculine egocentrism has prescripted an afterlife; Symbiotic Parallelism envisions a life after mankind. The first requires the death of Life; the second the death of Procrustes. Two alternatives: the first very actual and the second very real. As long as the means for universal Suicide exists, Life evolves in hiatus through finite time. Humanity has become totally responsible for the miracle of Life in its continuance. In the face of this, god withers...and in a very real sense apotheosis has occurred. Mankind is free to enjoin itself in a new symbiotic entelechy—parallel and syntonic. The date 8/6/45 should be enshrined in human cognizance as the death of Mankind and the beginning of Humanity...a new epoch. It is 1995. Five years until the Christian millennium and fifty years since the annihilation of Hiroshima. The condition of humanity is toxic, poisoned by an entelechy redundant and untransmuted...corrupting and corrupt. Mankind, unremitting and unregenerate, has become an inversion of procrustean intent: the triarchy is destroying itself. In a protracted hiatus of apotheosis postponed, commerce is consuming the pretensions and personae of religion and war leaving a Janus of hypocrisy, Procrustean trafficker in fear and greed. As this perception becomes ever more cognitional, its actuality manifest, masculine solipsistry denied, its prophetic eventuation becomes ever more caricatured—morbific and mordant, aberrant and anachronistic, invasive and pervasive. Pre-millennialism is rampant, still promising rapture and damnation. The politics of reversal and denial are in ascendancy.... Blinded by fear and suffocating in angst, we refuse to establish the one signpost which could save us all: Hiroshima 8/6/45. Dies Irae and Deus ex machina. The triarchy must be forced to confess its suicide. A new epoch has begun. And what of Art? Over-shadowed by technology and constrained by commerce, it seems vestigial and mimetic in this age of miracles, serving as distaff to science in gendered neutrality. And what of Feminine gendered entelechy? What then of Humanity's evolving Spirit? What then of Art? As Science expands actual truth through the means and miracles of technology, Art seems unable to command its true equivalency. As Hubble looks out toward the very beginnings of the universe, Art must look deep into Feminine entelechy for its own essentiality within the concepts of finite time. If, as it seems, a meliorating evolution is progressing, then a feminine primus interpares is nascent; and with the death of procrustean religionism, Feminine Spirituality is released. Is it, perhaps, Art's purpose to define and configure the mysteries of this repressed and muted essence, to give persona and presence to this buried truth? Heretofore this essence, this spirit, this truth has been revealed in moments of ecstasy—profound religious or aesthetic experiences wherein an opacity suddenly becomes transparent and revelation occurs: a cosmic orgasm...a miracle. Art, from its earliest manifestations through its most opaque servitude in masculine entelechy to contemporary autotelism can be judged authentic only in terms of its capacity for transparency. Historicity means nothing. Originality means nothing. Authorship or ownership mean nothing—only its capacity for transparency. Throughout the ages and isms of linear time, Art's personae have reflected the shifting tastes and tableaux of their coeval existence. These surface perceptions often have great historical and anthropological information; however, the denser the first plane of perception, the more opaque and difficult the transmutation from object to experience. Even the most, supposedly, autotelic works are burdened by the opacities of technique and culture hype, procrustean in motive and intent. And most works are only surface manifestations with little or no capacity for transparency and transcendence. These works simply are until they aren't, leaving a few, oh so few, windows to Feminine ethos: to reality and truth. Suppressed, patronized and feared, this ethos—this ethic—this sublime clarity has been carried, protected and hidden within works of Art. Undiluted and volatile, it is Creation itself, exhilarating and liberating and awesome in its revelation. The more authentic the work of art, the more imbued with Feminine entelechy...the more astute and articulate the artist, the more transparent the access and profound the experience. The Feminine, whether actualized as Female or realized transcendentally, has been protected and exploited throughout evolutionary time, treated primarily as vassal and vessel within masculine solipsism; the miracle of birth, subservient to the sacredness of sperm...the subjective experience subverted by objective worth. This relationship between masculine and Feminine evolved virtually intact until this century and then shifted drastically on 8/6/45. Though parity has not been achieved, self-recognition is progressing at an astonishing pace (this is also true of the gendered neuter) and the diagonal hegemony of masculine control is moving toward symbiotic parallelism. This creates a climate both curious and problematic: As Feminine entelechy actualizes, what then of Art? Will it devolve into a kind of usage—propaganda for an increasingly fragmented and divergent society? A merging with technology into a single-gendered neutrality functioning with pragmatic opacity in the satisfying of evolving sensuous need? As this fifty year hiatus progresses through finite time, there is increasing evidence that as masculine superiority is challenged and feminization occurs, Science (technology) becomes ever more miraculous and neutralizing: Feminine entelechy will soon share the once unique power of reproduction with the entelechy of Science. Gender identities are in flux—no longer absolute within the human equation. As the Feminine neutralizes Masculine hegemony, Science is neutralizing the Feminine. What then of Art? If the miracle of Creation is being regendered and actualized into the miracles of Science, what becomes of the liberating ecstasies of Art? What of transparencies and transcendence? What of the Spirit? Has precognitional apotheosis precluded Art's purpose—its raison d'être? As Symbiotic parallelism evolves, will Art become merely the vehicle for an opaque communication? If the epicenter of Feminine entelechy can be produced in a test-tube, does this serve to destroy the entire entelechy or, as the death of Masculine procrustean triarchy has served, to integrate Masculine entelechy into Symbiotic Parallelism? I believe that Art, authentic in its entelechy of transparency and transcendence, will flourish throughout Time Finite as it has flourished throughout infinite time. And that as Hubble seeks out the beginnings of Time, the artist—if he indeed be an artist—will continue to probe cognizance for the miracle of Creation. We are an evolving mystery—a braided circlet of parallel threads twisted and tied into a Gordian knot of perplexing simplicity. On the Sixth of August Nineteen Hundred and Forty-Five in a Japanese city named Hiroshima, the solution of Alexander was proffered in penultimate predation. Thus far humankind has rejected this solution and for the past fifty years has involved itself in an intensified struggle to untie or at least record the knotted threads. Even the most orthodox and fundamental of religionists seem not quite ready for Rapture and apotheosis. We live in hiatus knowing that everything has changed, but not knowing what. It is a time of exaggeration. The Christian millennium fervor verges on hysteria with fundamentalists trying to revert, convert and invert with procrustean zest. Science, not employed as the sword for the ultimate severing solution, has become the wellspring for an astonishing shower of technological miracles, obliterating all but the most fundamental differences between the sexes allowing for a new and liberating parallelism devoid of hegemonic masculine supremacy. Art, struggling to retain viability in a hyper-actualized climate, has hardened its fundamental identities of precious chattel and valued propagandist. Both poses are redundant and hypocritical. On the verge of a new century, a new millennium, a new epoch, I cannot imagine a more thrilling and challenging time to be an artist. The entire human experiment is in flux. As the Holocene epoch ends, humankind has conquered its planet and is now in absolute control of its destiny. It can exist or not exist. No more "God's Will"—no more excuses. No more dogma or "God's word." The prophecies have been fulfilled. Mankind has delivered the future to parallelism. Art entelechies must be equal, including the entelechy of the planet itself. By its own law of survival, Darwinism is being replaced by a new Law of Connectedness, and professions that promote and advance masculine hegemony recissioned: War surrogate Sports, militant religionism...all manifestations of Procrustes, recissioned. As parallelism evolves, so, too, will new myths and metaphors evolve within a new construct of essentiality. We mourn the loss of war because we mourn the loss of patriarchy because we mourn the loss of god, the death of god and all his metaphors. We live in an age of miracles; a renaissance of human entelechy wherein courage wears a different face. Our new heroes will not be killing each other in the names of god and country, building an ever-increasing density of separation and hate. Rather, they will be destroying the masks and songs of Procrustes: Nasrin, Faulkner, Meinhold, Dunning, Hill—New heroes for a new age...a new epoch of syntonic evolution. As the heroes and martyrs of hiatal time gradually shift cognizance from the masculine actual to the Feminine real, the evolving persona of art seems unfocused: its gendering unclear.... Feminine entelechy, liberated by the Masculine apotheosis of 8/6/45, must now define self as an entity within an evolving symbiotic Parallelism. As Feminine entelechy resolves into definition, so, too, will the Face of Art."

  

PROCRUSTES IN SITU is the first part of THE PROCRUSTES TRILOGY and consists of the elements in the above photograph as well as a large Study with its Predella.

 

As Robert Cremean wrote:

 

PROCRUSTES IN SITU attempts to illustrate the obvious and redundant visages of Procrustes. He is omnipresent within the human condition: cutting, trimming and stretching each individual to fit the beds of conformity. During this phase of the Trilogy, I came to see how essential he is to everything that we are. Without Procrustes, there is no coherence. Procrustes is the antithesis of chaos. He is also the enemy of Art.

 

Procrustes thrives on repeat, stasis, and order. His sole purpose is to determine and control. Anything that threatens his authority and the dimensions of his beds is trimmed away or stretched beyond its viable scope of importance. The enforced illusions of Procrustes are in constant conflict with the Artist’s desire for truth, no matter what the cost.

 

In PROCRUSTES IN SITU, the connection between Procrustes and nature, sexuality and reproduction is considered. The linear extension of the species gives Procrustes great authority within the strictures of society. This is acknowledged in the beds of the mother, the father, the young woman, the young man, the child, and fear. Procrustes controls these beds through instinct. We are born into them. By these he controls us all. Chaos is not a threat to Procrustes in his natural form but rather to the illusions that that form has itself constructed. It is this illusion of identity that centers the drama of Procrustes: Theseus versus Procrustes, Art versus culture, chaos versus illusion.

"The entheogen-inspired visionary art of certain indigenous peoples, such as the Huichol yarn paintings and the ayahuasca-inspired art of Pablo Amaringo, often exhibits this style, as does the psychedelic art movement of the 1960s counterculture. Sometimes the patterned art in clothing of indigenous peoples of Middle and South America exhibits horror vacui. For example the geometric molas of Kuna people and the traditional clothing on Shipibo-Conibo people."

A Haiku Note:

========================

Some Buddhism books

========================

Buddhism has no creator god and gives a central role to the doctrine of karma. The ‘four noble truths’ of Buddhism state that all existence is suffering, that the cause of suffering is desire, that freedom from suffering is nirvana, and that this is attained through the ‘eightfold’ path of ethical conduct, wisdom, and mental discipline (including meditation). There are two major traditions, Theravada and Mahayana.

(Apple Dictionary App)

===================================================

The Noble Eightfold Path describes the way to the end of suffering, as it was laid out by Siddhartha Gautama. It is a practical guideline to ethical and mental development with the goal of freeing the individual from attachments and delusions; and it finally leads to understanding the truth about all things. Together with the Four Noble Truths it constitutes the gist of Buddhism. Great emphasis is put on the practical aspect, because it is only through practice that one can attain a higher level of existence and finally reach Nirvana. The eight aspects of the path are not to be understood as a sequence of single steps, instead they are highly interdependent principles that have to be seen in relationship with each other.

 

1. Right View

 

Right view is the beginning and the end of the path, it simply means to see and to understand things as they really are and to realise the Four Noble Truths. As such, right view is the cognitive aspect of wisdom. It means to see things through, to grasp the impermanent and imperfect nature of worldly objects and ideas, and to understand the law of karma and karmic conditioning. Right view is not necessarily an intellectual capacity, just as wisdom is not just a matter of intelligence. Instead, right view is attained, sustained, and enhanced through all capacities of mind. It begins with the intuitive insight that all beings are subject to suffering and it ends with complete understanding of the true nature of all things. Since our view of the world forms our thoughts and our actions, right view yields right thoughts and right actions.

 

2. Right Intention

 

While right view refers to the cognitive aspect of wisdom, right intention refers to the volitional aspect, i.e. the kind of mental energy that controls our actions. Right intention can be described best as commitment to ethical and mental self-improvement. Buddha distinguishes three types of right intentions: 1. the intention of renunciation, which means resistance to the pull of desire, 2. the intention of good will, meaning resistance to feelings of anger and aversion, and 3. the intention of harmlessness, meaning not to think or act cruelly, violently, or aggressively, and to develop compassion.

 

3. Right Speech

 

Right speech is the first principle of ethical conduct in the eightfold path. Ethical conduct is viewed as a guideline to moral discipline, which supports the other principles of the path. This aspect is not self-sufficient, however, essential, because mental purification can only be achieved through the cultivation of ethical conduct. The importance of speech in the context of Buddhist ethics is obvious: words can break or save lives, make enemies or friends, start war or create peace. Buddha explained right speech as follows: 1. to abstain from false speech, especially not to tell deliberate lies and not to speak deceitfully, 2. to abstain from slanderous speech and not to use words maliciously against others, 3. to abstain from harsh words that offend or hurt others, and 4. to abstain from idle chatter that lacks purpose or depth. Positively phrased, this means to tell the truth, to speak friendly, warm, and gently and to talk only when necessary.

 

4. Right Action

 

The second ethical principle, right action, involves the body as natural means of expression, as it refers to deeds that involve bodily actions. Unwholesome actions lead to unsound states of mind, while wholesome actions lead to sound states of mind. Again, the principle is explained in terms of abstinence: right action means 1. to abstain from harming sentient beings, especially to abstain from taking life (including suicide) and doing harm intentionally or delinquently, 2. to abstain from taking what is not given, which includes stealing, robbery, fraud, deceitfulness, and dishonesty, and 3. to abstain from sexual misconduct. Positively formulated, right action means to act kindly and compassionately, to be honest, to respect the belongings of others, and to keep sexual relationships harmless to others. Further details regarding the concrete meaning of right action can be found in the Precepts.

 

5. Right Livelihood

 

Right livelihood means that one should earn one's living in a righteous way and that wealth should be gained legally and peacefully. The Buddha mentions four specific activities that harm other beings and that one should avoid for this reason: 1. dealing in weapons, 2. dealing in living beings (including raising animals for slaughter as well as slave trade and prostitution), 3. working in meat production and butchery, and 4. selling intoxicants and poisons, such as alcohol and drugs. Furthermore any other occupation that would violate the principles of right speech and right action should be avoided.

 

6. Right Effort

 

Right effort can be seen as a prerequisite for the other principles of the path. Without effort, which is in itself an act of will, nothing can be achieved, whereas misguided effort distracts the mind from its task, and confusion will be the consequence. Mental energy is the force behind right effort; it can occur in either wholesome or unwholesome states. The same type of energy that fuels desire, envy, aggression, and violence can on the other side fuel self-discipline, honesty, benevolence, and kindness. Right effort is detailed in four types of endeavours that rank in ascending order of perfection: 1. to prevent the arising of unarisen unwholesome states, 2. to abandon unwholesome states that have already arisen, 3. to arouse wholesome states that have not yet arisen, and 4. to maintain and perfect wholesome states already arisen.

 

7. Right Mindfulness

 

Right mindfulness is the controlled and perfected faculty of cognition. It is the mental ability to see things as they are, with clear consciousness. Usually, the cognitive process begins with an impression induced by perception, or by a thought, but then it does not stay with the mere impression. Instead, we almost always conceptualise sense impressions and thoughts immediately. We interpret them and set them in relation to other thoughts and experiences, which naturally go beyond the facticity of the original impression. The mind then posits concepts, joins concepts into constructs, and weaves those constructs into complex interpretative schemes. All this happens only half consciously, and as a result we often see things obscured. Right mindfulness is anchored in clear perception and it penetrates impressions without getting carried away. Right mindfulness enables us to be aware of the process of conceptualisation in a way that we actively observe and control the way our thoughts go. Buddha accounted for this as the four foundations of mindfulness: 1. contemplation of the body, 2. contemplation of feeling (repulsive, attractive, or neutral), 3. contemplation of the state of mind, and 4. contemplation of the phenomena.

 

8. Right Concentration

 

The eighth principle of the path, right concentration, refers to the development of a mental force that occurs in natural consciousness, although at a relatively low level of intensity, namely concentration. Concentration in this context is described as one-pointedness of mind, meaning a state where all mental faculties are unified and directed onto one particular object. Right concentration for the purpose of the eightfold path means wholesome concentration, i.e. concentration on wholesome thoughts and actions. The Buddhist method of choice to develop right concentration is through the practice of meditation. The meditating mind focuses on a selected object. It first directs itself onto it, then sustains concentration, and finally intensifies concentration step by step. Through this practice it becomes natural to apply elevated levels of concentration also in everyday situations.

We have always had a complex relationship with technology. There are perennial claims that it may come to dominate us, or in some way undermine human values. In the 5th century BC, Plato’s dialogue the Phaedrus contained an early critique of the technology of writing at the time of its widespread adoption: Socrates voices concerns that writing will undermine human knowledge and authority and will ultimately be destructive to the Athenian polis. We find echoes of this in some of the responses to contemporary media technologies from Wikipedia to Google to Facebook. Some suggest our dependence on a range of digital ‘cognitive extension technologies’, are dumbing down culture, or even changing the nature of human consciousness.

 

Neuroscientist Susan Greenfield has argued Facebook and related technologies are in danger of undermining children´s abilities to relate to each in a basic face-to-face manner, though these claims have been fiercely contested. Professor Sherry Turkle, author of the influential book Alone Together has suggested our ‘pathological’ addiction to social media is making us ‘less human’. Others, such as Nicholas Carr, author of The Shallows and novelist Zadie Smith argue it’s ‘flattening us out’, turning us into two-dimensional, dumbed-down, emotionally illiterate consumers.

 

Yet others believe human intelligence - rather being the simple outcome of evolution on a Pleistocene savannah - is always wrapped up with our use of technology. Our minds are not in the normal sense natural, or fixed. We may indeed think differently from our ancestors before telephones, aeroplanes, pharmacology; everything from the wheel to the locomotive has undoubtedly influenced our social relations and indeed our idea of ourselves as humans. So if human intelligence has always been forged in a relation to technology, is there really anything so special about the new technologies from a cognitive standpoint? Or, do our fears about the cognitive implications of the Web 2.0 say more about today’s cultural climate of determinism and pessimism about the future and a loss of faith in humanity? What has caused so many to view the internet and mobile technology so pessimistically?

Breathing requires coordinated movements of the diaphragm and intercostal muscles. When these muscles contract, air is drawn into the lungs, where hundreds of millions of tiny alveoli provide a surface where oxygen can diffuse into the blood and carbon dioxide can diffuse out. With each exhalation, these muscles relax, and air is forced back out.

Ten Lessons the Arts Teach

By Elliot Eisner

  

The arts teach children to make good judgments about qualitative relationships.

Unlike much of the curriculum in which correct answers and rules prevail, in the arts, it

is judgment rather than rules that prevail.

 

The arts teach children that problems can have more than one solution

and that questions can have more than one answer.

 

The arts celebrate multiple perspectives.

One of their large lessons is that there are many ways to see and interpret the world.

 

The arts teach children that in complex forms of problem solving

purposes are seldom fixed, but change with circumstance and opportunity. Learning in the arts requires the ability and a willingness to surrender to the unanticipated possibilities of the work as it unfolds.

 

The arts make vivid the fact that neither words in their literal form nor number exhaust what we can know. The limits of our language do not define the limits of our cognition.

 

The arts teach students that small differences can have large effects.

The arts traffic in subtleties.

 

The arts teach students to think through and within a material.

All art forms employ some means through which images become real.

 

The arts help children learn to say what cannot be said.

When children are invited to disclose what a work of art helps them feel, they must reach into their poetic capacities to find the words that will do the job.

 

The arts enable us to have experience we can have from no other source

and through such experience to discover the range and variety of what we are capable of feeling.

 

The arts’ position in the school curriculum symbolizes to the young

what adults believe is important.

    

This was probably our favorite store in the town!

Here I could find many answers to my insatiable curiosity . . .

but still, NO books on Brattleboro! So I'm in the process of creating one!

And behind/within these windows lie a bit of the oxymoronic feelings I was inhaling the entire weekend . . . a "peaceful, idyllic" scene of a cow grazing in a green pasture in rural Vermont, with a contrasting poster on controversial issues . . . (see bumper stickers below for more protests) . . . hmmmmm . . . a great dichotomy, don't you think? maybe that's what I was sensing? Time will tell . . . just first impressions . . . .

 

“We really need to change that historic dichotomy of cognition on the one hand, emotions on the other hand, and realize that our emotions are the fuel that gives rise to social behavior but also to different levels of intelligence.” ~ Stanley Greenspan ~

And what of the Eightfold Path?

======================================================

The Noble Eightfold Path describes the way to the end of suffering, as it was laid out by Siddhartha Gautama. It is a practical guideline to ethical and mental development with the goal of freeing the individual from attachments and delusions; and it finally leads to understanding the truth about all things. Together with the Four Noble Truths it constitutes the gist of Buddhism. Great emphasis is put on the practical aspect, because it is only through practice that one can attain a higher level of existence and finally reach Nirvana. The eight aspects of the path are not to be understood as a sequence of single steps, instead they are highly interdependent principles that have to be seen in relationship with each other.

 

1. Right View

 

Right view is the beginning and the end of the path, it simply means to see and to understand things as they really are and to realise the Four Noble Truths. As such, right view is the cognitive aspect of wisdom. It means to see things through, to grasp the impermanent and imperfect nature of worldly objects and ideas, and to understand the law of karma and karmic conditioning. Right view is not necessarily an intellectual capacity, just as wisdom is not just a matter of intelligence. Instead, right view is attained, sustained, and enhanced through all capacities of mind. It begins with the intuitive insight that all beings are subject to suffering and it ends with complete understanding of the true nature of all things. Since our view of the world forms our thoughts and our actions, right view yields right thoughts and right actions.

 

2. Right Intention

 

While right view refers to the cognitive aspect of wisdom, right intention refers to the volitional aspect, i.e. the kind of mental energy that controls our actions. Right intention can be described best as commitment to ethical and mental self-improvement. Buddha distinguishes three types of right intentions: 1. the intention of renunciation, which means resistance to the pull of desire, 2. the intention of good will, meaning resistance to feelings of anger and aversion, and 3. the intention of harmlessness, meaning not to think or act cruelly, violently, or aggressively, and to develop compassion.

 

3. Right Speech

 

Right speech is the first principle of ethical conduct in the eightfold path. Ethical conduct is viewed as a guideline to moral discipline, which supports the other principles of the path. This aspect is not self-sufficient, however, essential, because mental purification can only be achieved through the cultivation of ethical conduct. The importance of speech in the context of Buddhist ethics is obvious: words can break or save lives, make enemies or friends, start war or create peace. Buddha explained right speech as follows: 1. to abstain from false speech, especially not to tell deliberate lies and not to speak deceitfully, 2. to abstain from slanderous speech and not to use words maliciously against others, 3. to abstain from harsh words that offend or hurt others, and 4. to abstain from idle chatter that lacks purpose or depth. Positively phrased, this means to tell the truth, to speak friendly, warm, and gently and to talk only when necessary.

 

4. Right Action

 

The second ethical principle, right action, involves the body as natural means of expression, as it refers to deeds that involve bodily actions. Unwholesome actions lead to unsound states of mind, while wholesome actions lead to sound states of mind. Again, the principle is explained in terms of abstinence: right action means 1. to abstain from harming sentient beings, especially to abstain from taking life (including suicide) and doing harm intentionally or delinquently, 2. to abstain from taking what is not given, which includes stealing, robbery, fraud, deceitfulness, and dishonesty, and 3. to abstain from sexual misconduct. Positively formulated, right action means to act kindly and compassionately, to be honest, to respect the belongings of others, and to keep sexual relationships harmless to others. Further details regarding the concrete meaning of right action can be found in the Precepts.

 

5. Right Livelihood

 

Right livelihood means that one should earn one's living in a righteous way and that wealth should be gained legally and peacefully. The Buddha mentions four specific activities that harm other beings and that one should avoid for this reason: 1. dealing in weapons, 2. dealing in living beings (including raising animals for slaughter as well as slave trade and prostitution), 3. working in meat production and butchery, and 4. selling intoxicants and poisons, such as alcohol and drugs. Furthermore any other occupation that would violate the principles of right speech and right action should be avoided.

 

6. Right Effort

 

Right effort can be seen as a prerequisite for the other principles of the path. Without effort, which is in itself an act of will, nothing can be achieved, whereas misguided effort distracts the mind from its task, and confusion will be the consequence. Mental energy is the force behind right effort; it can occur in either wholesome or unwholesome states. The same type of energy that fuels desire, envy, aggression, and violence can on the other side fuel self-discipline, honesty, benevolence, and kindness. Right effort is detailed in four types of endeavours that rank in ascending order of perfection: 1. to prevent the arising of unarisen unwholesome states, 2. to abandon unwholesome states that have already arisen, 3. to arouse wholesome states that have not yet arisen, and 4. to maintain and perfect wholesome states already arisen.

 

7. Right Mindfulness

 

Right mindfulness is the controlled and perfected faculty of cognition. It is the mental ability to see things as they are, with clear consciousness. Usually, the cognitive process begins with an impression induced by perception, or by a thought, but then it does not stay with the mere impression. Instead, we almost always conceptualise sense impressions and thoughts immediately. We interpret them and set them in relation to other thoughts and experiences, which naturally go beyond the facticity of the original impression. The mind then posits concepts, joins concepts into constructs, and weaves those constructs into complex interpretative schemes. All this happens only half consciously, and as a result we often see things obscured. Right mindfulness is anchored in clear perception and it penetrates impressions without getting carried away. Right mindfulness enables us to be aware of the process of conceptualisation in a way that we actively observe and control the way our thoughts go. Buddha accounted for this as the four foundations of mindfulness: 1. contemplation of the body, 2. contemplation of feeling (repulsive, attractive, or neutral), 3. contemplation of the state of mind, and 4. contemplation of the phenomena.

 

8. Right Concentration

 

The eighth principle of the path, right concentration, refers to the development of a mental force that occurs in natural consciousness, although at a relatively low level of intensity, namely concentration. Concentration in this context is described as one-pointedness of mind, meaning a state where all mental faculties are unified and directed onto one particular object. Right concentration for the purpose of the eightfold path means wholesome concentration, i.e. concentration on wholesome thoughts and actions. The Buddhist method of choice to develop right concentration is through the practice of meditation. The meditating mind focuses on a selected object. It first directs itself onto it, then sustains concentration, and finally intensifies concentration step by step. Through this practice it becomes natural to apply elevated levels of concentration also in everyday situations.

Guanyin is an East Asian spiritual figure of mercy, and a bodhisattva associated with compassion as venerated by Mahayana Buddhists. The name Guanyin is short for Guanshiyin, which means "Perceiving the Sounds (or Cries) of the World". She is also sometimes referred to as Guanyin Bodhisattva (Chinese: 觀音菩薩). (Wikipedia)

Brief synthesis

 

The Ħal Saflieni Hypogeum (underground cemetery) was discovered in 1902 on a hill overlooking the innermost part of the Grand Harbour of Valletta, in the town of Paola. It is a unique prehistoric monument, which seems to have been conceived as an underground cemetery, originally containing the remains of about 7,000 individuals. The cemetery was in use throughout the Żebbuġ, Ġgantija and Tarxien Phases of Maltese Prehistory, spanning from around 4000 B.C. to 2500 B.C.

 

Originally, one entered the Ħal Saflieni Hypogeum through a structure at ground level. Only a few blocks of this entrance building have been discovered, and its form and dimensions remain uncertain. The plan of the Hypogeum itself is a series of three superimposed levels of chambers cut into soft globigerina limestone, using only chert, flint and obsidian tools and antlers. The earliest of the three levels is the uppermost, scooped out of the brow of a hill. A number of openings and chambers for the burial of the dead were then cut into the sides of the cavity.

 

The two lower levels were also hewn entirely out of the natural rock. Some natural daylight reached the middle level through a small opening from the upper level, but artificial lighting must have been used to navigate through some of the middle level chambers and the lowest level, which is 10.60 m below the present ground level.

 

One of the most striking characteristics of the Ħal Saflieni Hypogeum is that some of the chambers appear to have been cut in imitation of the architecture of the contemporary, above-ground megalithic temples. Features include false bays, inspired by trilithon doorways, and windows. Most importantly, some of the chambers have ceilings with one ring of carved stone overhanging the one below to imitate a roof of corbelled masonry. This form echoes the way in which some of the masonry walls of the contemporary above-ground temple chambers are corbelled inwards, suggesting that they too were originally roofed over.

 

Some of the walls and ceilings of the chambers were decorated with spiral and honey-comb designs in red ochre, a mineral pigment. These decorations are the only prehistoric wall paintings found on the Maltese Islands. In one of these decorated chambers, there is a small niche which echoes when someone speaks into it. While this effect may not have been created intentionally, it may well have been exploited as part of the rituals that took place within the chambers.

 

Excavation of the Ħal Saflieni Hypogeum produced a wealth of archaeological material, including numerous human bones, which suggests that the burial ritual had more than one stage. It appears that bodies were probably left exposed until the flesh had decomposed and fallen off. The remaining bones and what appear to be some of the personal belongings were then gathered and buried within the chambers together with copious amounts of red ochre. The use of ochre seems to have been a part of the ritual, perhaps to infuse the bones with the colour of blood and life. Individuals were not buried separately, but piled onto each other.

 

Artefacts recovered from the site include pottery vessels decorated in intricate designs, shell buttons, stone and clay beads and amulets, as well as little stone carved animals and birds that may have originally been worn as pendants. The most striking finds are stone and clay figurines depicting human figures. The most impressive of these figures is that showing a woman lying on a bed or ‘couch’, popularly known as the ‘Sleeping Lady’. This figure is a work of art in itself, demonstrating a keen eye for detail.

 

Criterion (iii): The Ħal Saflieni Hypogeum is a unique monument of exceptional value. It is the only known European example of a subterranean ‘labyrinth’ from about 4,000 B.C. to 2,500 B.C. The quality of its architecture and its remarkable state of preservation make it an essential prehistoric monument.

 

Integrity

 

The Ħal Saflieni Hypogeum is one of the best preserved and most extensive environments that have survived from the Neolithic. With the exception of the fragmentary remains of the above-ground entrance, all the key attributes of the property, including the architectural details and painted wall decorations, have remained intact within the boundaries.

 

The main threats to the preservation of the Ħal Saflieni Hypogeum are the fluctuating temperature and relative humidity levels within the site, as well as water infiltration and biological infestations.

 

Authenticity

 

The Ħal Saflieni Hypogeum is one of the two most important prehistoric burial sites in the Maltese islands and is very well preserved, unlike the fragmentary remains that usually survive from the above-ground structures of this period.

 

The unusual preservation of the rock-cut chambers allows the study of a system of interconnecting spaces very much as they were conceived and experienced by a Neolithic mind. The imitation of the interior of a megalithic temple built above ground not only provides evidence on the corbelling system that was used to roof the temples, but is also important in terms of the development of human processes of cognition and representation.

 

The Ħal Saflieni Hypogeum has also yielded several important artefacts of great artistic significance. Foremost amongst these is the so-called ‘Sleeping Lady’, a miniature ceramic figurine that is widely held to be one of the great masterpieces of prehistoric anthropomorphic representation.

 

Protection and management requirements

 

The principal legal instrument for the protection of cultural heritage resources in Malta is the Cultural Heritage Act (2002), which provides for and regulates national bodies for the protection and management of cultural heritage resources. Building development and land use is regulated by the Environment and Development Planning Act (2010 and subsequent amendments), which provides for and regulates the Malta Environment and Planning Authority. The Ħal Saflieni Hypogeum is protected by a buffer zone, and both the Ħal Saflieni Hypogeum and its buffer zone are formally designated by the Malta Environment and Planning Authority as a Grade A archaeological site, which means they are subject to wide-ranging restrictions of building development.

 

A programme of monitoring and research, launched in order to understand the microclimate of the Hypogeum, was followed by a project for the conservation of the property, designed and implemented in the 1990s. Houses directly above the site were acquired and dismantled; light levels within the property are strictly controlled; and visitor numbers limited. These measures have helped to maintain stable temperature and humidity levels, which continue to be monitored closely.

========================================================

The Noble Eightfold Path describes the way to the end of suffering, as it was laid out by Siddhartha Gautama. It is a practical guideline to ethical and mental development with the goal of freeing the individual from attachments and delusions; and it finally leads to understanding the truth about all things. Together with the Four Noble Truths it constitutes the gist of Buddhism. Great emphasis is put on the practical aspect, because it is only through practice that one can attain a higher level of existence and finally reach Nirvana. The eight aspects of the path are not to be understood as a sequence of single steps, instead they are highly interdependent principles that have to be seen in relationship with each other.

 

1. Right View

 

Right view is the beginning and the end of the path, it simply means to see and to understand things as they really are and to realise the Four Noble Truths. As such, right view is the cognitive aspect of wisdom. It means to see things through, to grasp the impermanent and imperfect nature of worldly objects and ideas, and to understand the law of karma and karmic conditioning. Right view is not necessarily an intellectual capacity, just as wisdom is not just a matter of intelligence. Instead, right view is attained, sustained, and enhanced through all capacities of mind. It begins with the intuitive insight that all beings are subject to suffering and it ends with complete understanding of the true nature of all things. Since our view of the world forms our thoughts and our actions, right view yields right thoughts and right actions.

 

2. Right Intention

 

While right view refers to the cognitive aspect of wisdom, right intention refers to the volitional aspect, i.e. the kind of mental energy that controls our actions. Right intention can be described best as commitment to ethical and mental self-improvement. Buddha distinguishes three types of right intentions: 1. the intention of renunciation, which means resistance to the pull of desire, 2. the intention of good will, meaning resistance to feelings of anger and aversion, and 3. the intention of harmlessness, meaning not to think or act cruelly, violently, or aggressively, and to develop compassion.

 

3. Right Speech

 

Right speech is the first principle of ethical conduct in the eightfold path. Ethical conduct is viewed as a guideline to moral discipline, which supports the other principles of the path. This aspect is not self-sufficient, however, essential, because mental purification can only be achieved through the cultivation of ethical conduct. The importance of speech in the context of Buddhist ethics is obvious: words can break or save lives, make enemies or friends, start war or create peace. Buddha explained right speech as follows: 1. to abstain from false speech, especially not to tell deliberate lies and not to speak deceitfully, 2. to abstain from slanderous speech and not to use words maliciously against others, 3. to abstain from harsh words that offend or hurt others, and 4. to abstain from idle chatter that lacks purpose or depth. Positively phrased, this means to tell the truth, to speak friendly, warm, and gently and to talk only when necessary.

 

4. Right Action

 

The second ethical principle, right action, involves the body as natural means of expression, as it refers to deeds that involve bodily actions. Unwholesome actions lead to unsound states of mind, while wholesome actions lead to sound states of mind. Again, the principle is explained in terms of abstinence: right action means 1. to abstain from harming sentient beings, especially to abstain from taking life (including suicide) and doing harm intentionally or delinquently, 2. to abstain from taking what is not given, which includes stealing, robbery, fraud, deceitfulness, and dishonesty, and 3. to abstain from sexual misconduct. Positively formulated, right action means to act kindly and compassionately, to be honest, to respect the belongings of others, and to keep sexual relationships harmless to others. Further details regarding the concrete meaning of right action can be found in the Precepts.

 

5. Right Livelihood

 

Right livelihood means that one should earn one's living in a righteous way and that wealth should be gained legally and peacefully. The Buddha mentions four specific activities that harm other beings and that one should avoid for this reason: 1. dealing in weapons, 2. dealing in living beings (including raising animals for slaughter as well as slave trade and prostitution), 3. working in meat production and butchery, and 4. selling intoxicants and poisons, such as alcohol and drugs. Furthermore any other occupation that would violate the principles of right speech and right action should be avoided.

 

6. Right Effort

 

Right effort can be seen as a prerequisite for the other principles of the path. Without effort, which is in itself an act of will, nothing can be achieved, whereas misguided effort distracts the mind from its task, and confusion will be the consequence. Mental energy is the force behind right effort; it can occur in either wholesome or unwholesome states. The same type of energy that fuels desire, envy, aggression, and violence can on the other side fuel self-discipline, honesty, benevolence, and kindness. Right effort is detailed in four types of endeavours that rank in ascending order of perfection: 1. to prevent the arising of unarisen unwholesome states, 2. to abandon unwholesome states that have already arisen, 3. to arouse wholesome states that have not yet arisen, and 4. to maintain and perfect wholesome states already arisen.

 

7. Right Mindfulness

 

Right mindfulness is the controlled and perfected faculty of cognition. It is the mental ability to see things as they are, with clear consciousness. Usually, the cognitive process begins with an impression induced by perception, or by a thought, but then it does not stay with the mere impression. Instead, we almost always conceptualise sense impressions and thoughts immediately. We interpret them and set them in relation to other thoughts and experiences, which naturally go beyond the facticity of the original impression. The mind then posits concepts, joins concepts into constructs, and weaves those constructs into complex interpretative schemes. All this happens only half consciously, and as a result we often see things obscured. Right mindfulness is anchored in clear perception and it penetrates impressions without getting carried away. Right mindfulness enables us to be aware of the process of conceptualisation in a way that we actively observe and control the way our thoughts go. Buddha accounted for this as the four foundations of mindfulness: 1. contemplation of the body, 2. contemplation of feeling (repulsive, attractive, or neutral), 3. contemplation of the state of mind, and 4. contemplation of the phenomena.

 

8. Right Concentration

 

The eighth principle of the path, right concentration, refers to the development of a mental force that occurs in natural consciousness, although at a relatively low level of intensity, namely concentration. Concentration in this context is described as one-pointedness of mind, meaning a state where all mental faculties are unified and directed onto one particular object. Right concentration for the purpose of the eightfold path means wholesome concentration, i.e. concentration on wholesome thoughts and actions. The Buddhist method of choice to develop right concentration is through the practice of meditation. The meditating mind focuses on a selected object. It first directs itself onto it, then sustains concentration, and finally intensifies concentration step by step. Through this practice it becomes natural to apply elevated levels of concentration also in everyday situations.

 

The first fascinating speaker in the bowels of the Bio-X building (at the Imitating Life Symposium this morning) was John Donoghue, Professor of Neuroscience at Brown University on the topic of "Turning Thoughts into Action: Neural Interfaces to Restore Movement in Humans with Paralysis"

 

Here is opens with an interesting image in the bottom left corner – the first cardiac pacemaker (a full push cart of equipment). Neurotech is in an early phase of development, although he notes that 50K people already have deep drain stimulation implants.

 

“Many diseases impair sensory input but leave cognition intact (spinal cord injury, ALS, stroke, limb loss…)”

 

He inserts a 4 sq. mm array of 100 neural probes into the M1 arm knob of the cortex. With a random sample of neural signaling from that region of the brain, and some Kalman filtering, patients can instantly control the cursor on screen (unlike biofeedback or sensory remapping which require training). They can deduce motor intent from a sample of an average of 24 neurons.

 

When connected to a robot hand for the first time, and asked to “make a fist” the patient exclaimed “holy sh*t” as it worked the first time.

 

Prior to the experiments, open questions included: Do the neurons stay active (other work indicates that the motor cortex reorganizes within minutes of decoupled sensory input)? Can thinking still activate the motor neurons? The test patients had been in sensory deprivation for 2-9 years prior. Will there be scarring and degradation over time? One patient is three years in. What are the neural plasticity effects?

A collaborative workshop interfacing movement art practices, digital creativity, portable computation and networked systems.

 

This workshop is a collaborative lab to creatively explore the contemporary approaches, practices and aesthetics of self organization and of complex systems within the dynamic couplings of mind, body and information/data flows.

This workshop is an open space for experimentation and inquiry within a well defined theoretical/aesthetic frame and open space format: the participants self-organize in different node projects (collaborative and flexible groups) in order to investigate and deploy bottom-up architectures as compositional prototyping strategies and processes. It explores interactivity plus generativity.

An embodied/distributed cognition approach is used to generate physical activities and games, guided discussions/conversations about relevant artists works and concepts exploring the aesthetic of complex systems and emergence.

Open source technologies and methodologies will be explored in combination with composition in real-time.

Inter and trans-disciplinary explorations are encouraged and diversity is the main asset.

Several nodes of research projects are suggested:

Sampling, recombinations and mashups

New Internet technologies (web 2.0) and collaborative creation

Post-pc technologies apps, tablets and mobile technologies

Life logging and creative process

Media Capturing and Real time processing

Bottom-up architectures of generative systems

Hybrid realities and alternative sites

Portable cameras and video production

Online video and video straming

Cloud/social computing

Locative media/Mobile

Performance, rule systems and algorithms.

Computer aided choreography

Portable hardware as interfaces/interactive media control

Social media for distributed creativity and knowledge production

Networked documentaries/storytelling.

October 2011

I was just reading the latest New Scientist on Neanderthal thinking, and was reminded of the latest revelation from my family’s genotyping. My Mom looks to be quite the beast. =)

 

You probably saw the news last year that “Any human whose ancestral group developed outside Africa has a little Neanderthal in them – between 1 and 4 per cent of their genome. In other words, humans and Neanderthals had sex and had hybrid offspring. A small amount of that genetic mingling survives in "non-Africans" today: Neanderthals didn't live in Africa, which is why sub-Saharan African populations have no trace of Neanderthal DNA. It's impossible to know how often humans invited Neanderthals back to their cave (and vice versa), but the genome data offers some intriguing details. It must have been at least 45,000 years ago… suggesting that interbreeding occurred before those populations split. The timing makes the Middle East the likeliest place where humans leaving Africa and resident Neanderthals did the deed.” (New Scientist)

 

And a different IBM analysis of my paternal line shows my ancestors were in the second major wave out of Africa, settling in the Middle East at that very time. And presumably getting friendly with the locals.

 

More recently, palaeoanthropologists have learned a great deal about how Neanderthals think, and that was tonight’s reading:

 

“We know Neanderthal brains were a bit larger than ours and were shaped a bit differently. And we know where they lived, what they ate and how they got it.

 

Looking closely at the choices Neanderthals made when they manufactured and used tools shows that they organised their technical activities much as artisans... Like blacksmiths, they relied on "expert" cognition, a form of observational learning and practice acquired through apprenticeship that relies heavily on long-term procedural memory.

 

The only obvious difference between Neanderthal technical thinking and ours lay in innovation. Although Neanderthals invented the practice of hafting stone points onto spears, this was one of very few innovations over several hundred thousand years. Active invention relies on thinking by analogy and a good amount of working memory, implying they may have had a reduced capacity in these respects.

 

But while Neanderthals would have had a variety of personality types, just as we do, their way of life would have selected for an average profile quite different from ours. Jo or Joe Neanderthal were neophobic, dogmatic and xenophobic.

 

So we could have recognised and interacted with Neanderthals, but we would have noticed these significant cognitive differences. They would have been better at well-learned, expert cognition than modern humans, but not as good at the development of novel solutions. They were adept at intimate, small-scale social cognition, but lacked the cognitive tools to interact with acquaintances and strangers, including the extensive use of symbols.

 

In the final count, when Neanderthals and modern humans found themselves competing across the European landscape 30,000 years ago, those cognitive differences may well have been decisive in seeing off the Neanderthals.” (New Scientist, Jan 14, 2012)

Crocodiles (family Crocodylidae) or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. The term crocodile is sometimes used even more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (family Alligatoridae), the gharial and false gharial (family Gavialidae) among other extinct taxa.

 

Although they appear similar, crocodiles, alligators and the gharial belong to separate biological families. The gharial, with its narrow snout, is easier to distinguish, while morphological differences are more difficult to spot in crocodiles and alligators. The most obvious external differences are visible in the head, with crocodiles having narrower and longer heads, with a more V-shaped than a U-shaped snout compared to alligators and caimans. Another obvious trait is that the upper and lower jaws of the crocodiles are the same width, and the teeth in the lower jaw fall along the edge or outside the upper jaw when the mouth is closed; therefore, all teeth are visible, unlike an alligator, which possesses in the upper jaw small depressions into which the lower teeth fit. Also, when the crocodile's mouth is closed, the large fourth tooth in the lower jaw fits into a constriction in the upper jaw. For hard-to-distinguish specimens, the protruding tooth is the most reliable feature to define the species' family. Crocodiles have more webbing on the toes of the hind feet and can better tolerate saltwater due to specialized salt glands for filtering out salt, which are present, but non-functioning, in alligators. Another trait that separates crocodiles from other crocodilians is their much higher levels of aggression.

 

Crocodile size, morphology, behaviour and ecology differ somewhat among species. However, they have many similarities in these areas as well. All crocodiles are semiaquatic and tend to congregate in freshwater habitats such as rivers, lakes, wetlands and sometimes in brackish water and saltwater. They are carnivorous animals, feeding mostly on vertebrates such as fish, reptiles, birds and mammals, and sometimes on invertebrates such as molluscs and crustaceans, depending on species and age. All crocodiles are tropical species that, unlike alligators, are very sensitive to cold. They separated from other crocodilians during the Eocene epoch, about 55 million years ago. Many species are at the risk of extinction, some being classified as critically endangered.

 

Etymology

The word crocodile comes from the Ancient Greek krokódilos (κροκόδιλος) meaning 'lizard', used in the phrase ho krokódilos tou potamoú, "the lizard of the (Nile) river". There are several variant Greek forms of the word attested, including the later form krokódeilos (κροκόδειλος) found cited in many English reference works. In the Koine Greek of Roman times, krokodilos and krokodeilos would have been pronounced identically, and either or both may be the source of the Latinized form crocodīlus used by the ancient Romans. It has been suggested, but it is not certain that the word crocodilos or crocodeilos is a compound of krokè ('pebbles'), and drilos/dreilos ('worm'), although drilos is only attested as a colloquial term for 'penis'. It is ascribed to Herodotus, and supposedly describes the basking habits of the Egyptian crocodile.

 

The form crocodrillus is attested in Medieval Latin. It is not clear whether this is a medieval corruption or derives from alternative Greco-Latin forms (late Greek corcodrillos and corcodrillion are attested). A (further) corrupted form cocodrille is found in Old French and was borrowed into Middle English as cocodril(le). The Modern English form crocodile was adapted directly from the Classical Latin crocodīlus in the 16th century, replacing the earlier form. The use of -y- in the scientific name Crocodylus (and forms derived from it) is a corruption introduced by Laurenti (1768).

 

Species

Species nameImageDistributionDescription/Comments

American crocodile (Crocodylus acutus)Throughout the Caribbean Basin, including many of the Caribbean islands and South Florida.A larger sized species, with a greyish colour and a prominent V-shaped snout. Prefers brackish water, but also inhabits lower stretches of rivers and true marine environments. This is one of the rare species that exhibits regular sea-going behaviour, which explains the great distribution throughout the Caribbean. It is also found in hypersaline lakes such as Lago Enriquillo, in the Dominican Republic, which has one of the largest populations of this species. Diet consists mostly of aquatic and terrestrial vertebrates. Classified as Vulnerable, but certain local populations under greater threat.

Hall's New Guinea crocodile (Crocodylus halli)The island of New Guinea, south of the New Guinea HighlandsA smaller species that closely resembles and was long classified under the New Guinea crocodile, which it is now considered to be genetically distinct from. It lives south of the mountain barrier that divides the two species' ranges. It can be physically distinguished from the New Guinea crocodile by its shorter maxilla and enlarged postcranial elements. Cranial elements can still widely vary within the species, with populations from Lake Murray having much wider heads than those from the Aramia River.

Orinoco crocodile (Crocodylus intermedius)Colombia and VenezuelaThis is a large species with a relatively elongated snout and a pale tan coloration with scattered dark brown markings. Lives primarily in the Orinoco Basin. Despite having a rather narrow snout, preys on a wide variety of vertebrates, including large mammals. It is a Critically Endangered species.

Freshwater crocodile (Crocodylus johnstoni)Northern AustraliaA smaller species with a narrow and elongated snout. It has light brown coloration with darker bands on body and tail. Lives in rivers with considerable distance from the sea, to avoid confrontations with saltwater crocodiles. Feeds mostly on fish and other small vertebrates.

Philippine crocodile (Crocodylus mindorensis)Endemic to the PhilippinesThis is a relatively small species with a rather broader snout. It has heavy dorsal armour and a golden-brown colour that darkens as the animal matures. Prefers freshwater habitats and feeds on a variety of small to medium sized vertebrates. This species is Critically Endangered and the most severely threatened species of crocodile.

Morelet's crocodile (Crocodylus moreletii)Atlantic regions of Mexico, Belize and GuatemalaA small to medium sized crocodile with a rather broad snout. It has a dark greyish-brown colour and is found in mostly various freshwater habitats. Feeds on mammals, birds and reptiles. It is listed as Least Concern.

Nile crocodile (Crocodylus niloticus)Sub-saharan AfricaA large and aggressive species with a broad snout, especially in older animals. It has a dark bronze coloration and darkens as the animal matures. Lives in a variety of freshwater habitats but is also found in brackish water. It is an apex predator that is capable of taking a wide array of African vertebrates, including large ungulates and other predators. This species is listed as Least Concern.

New Guinea crocodile (Crocodylus novaeguineae)The island of New Guinea, north of the New Guinea HighlandsA smaller species of crocodile with a grey-brown colour and dark brown to black markings on the tail. The young have a narrower V-shaped snout that becomes wider as the animal matures. Prefers freshwater habitats, even though is tolerant to salt water, in order to avoid competition and predation by the saltwater crocodile. This species feeds on small to mid-sized vertebrates.

Mugger crocodile (Crocodylus palustris)The Indian subcontinent and surrounding countriesThis is a modest sized crocodile with a very broad snout and an alligator-like appearance. It has dark-grey to brown coloration. Enlarged scutes around the neck make it a heavily armoured species. Prefers slow moving rivers, swamps and lakes. It can also be found in coastal swamps but avoids areas populated by saltwater crocodiles. Feeds on a wide array of vertebrates.

Saltwater crocodile (Crocodylus porosus)Throughout Southeast Asia, Northern Australia and surrounding watersThe largest living reptile and most aggressive of all crocodiles. It is a big-headed species and has a relatively broad snout, especially when older. The coloration is pale yellow with black stripes when young but dark greenish-drab coloured as adults. Lives in brackish and marine environments as well as lower stretches of rivers. This species has the greatest distribution of all crocodiles. Tagged specimens showed long-distance marine travelling behaviour. It is the apex predator throughout its range and preys on virtually any animal within its reach. It is classified as Least Concern with several populations under greater risk.

Borneo crocodile (Crocodylus raninus)Island of Borneo in Southeast AsiaA freshwater species of crocodile that has been considered a synonym of the saltwater crocodile.

Cuban crocodile (Crocodylus rhombifer)Found only in the Zapata Swamp and Isle of Youth of CubaIt is a small but extremely aggressive species of crocodile that prefers freshwater swamps. The coloration is vibrant even as adults and the scales have a "pebbled" appearance. It is a relatively terrestrial species with agile locomotion on land, and sometimes displays terrestrial hunting. The snout is broad with a thick upper-jaw and large teeth. The unique characteristics and fossil record indicates a rather specialized diet in the past, preying on megafauna such as the giant sloth. This species sometimes displays pack-hunting behaviour, which might have been the key to hunting large species in the past, despite its small size.[ Today most prey are small to medium sized vertebrates. It is Critically Endangered, and the remaining wild population is under threat of hybridization.

Siamese crocodile (Crocodylus siamensis)Indonesia, Brunei, East Malaysia and southern IndochinaA fairly small crocodile that prefers freshwater habitats. It has a relatively broad snout and olive-green to dark green coloration. It feeds on a variety of small to mid-sized vertebrates. Listed as Critically Endangered, but might be already extinct in the wild; status is unknown.

West African crocodile (Crocodylus suchus)Western and Central AfricaRecent studies revealed that this is distinct species from the larger Nile crocodile. It has a slightly narrower snout and is much smaller compared to its larger cousin.

Osborn’s dwarf crocodile (Osteolaemus osborni)Western AfricaIt is the smallest of all living crocodiles. It is a heavily armoured species with uniform black coloration in adults, while juveniles have a lighter brown banding. Lives in the tropical forests of Western Africa. Feeds on small vertebrates and large aquatic invertebrates. It is a fairly terrestrial species and exhibits terrestrial hunting, especially at night.

Dwarf crocodile (Osteolaemus tetraspis)Western AfricaIt is the smallest of all living crocodiles. It belongs to its own monotypic genus; however, new studies indicate there might be two or even three distinct species. It is a heavily armoured species with uniform black coloration in adults, while juveniles have a lighter brown banding. Lives in the tropical forests of Western Africa. Feeds on small vertebrates and large aquatic invertebrates. It is a fairly terrestrial species and exhibits terrestrial hunting, especially at night. This species is classified as Vulnerable.

West African slender-snouted crocodile (Mecistops cataphractus)Western AfricaA medium sized species with a narrow and elongated snout. Lives in freshwater habitats within tropical forests of the continent. Feeds mostly on fish but also other small to medium sized vertebrates. It is a Critically Endangered species.

Central African slender-snouted crocodile (Mecistops leptorhynchus)Central AfricaA medium sized species found in watery areas in dense rainforest. Feeds largely on fish. Insufficient conservation data, but was classified as Critically Endangered when lumped with M. cataphractus, although M. leptorhynchus is doing better in its home range.

For information on Tomistoma or false gharial, that is recently not considered as a true crocodile, see False gharial.

 

Characteristics

A crocodile's physical traits allow it to be a successful predator. Its external morphology is a sign of its aquatic and predatory lifestyle. Its streamlined body enables it to swim swiftly; it also tucks its feet to the side while swimming, making it faster by decreasing water resistance. Crocodiles have webbed feet which, though not used to propel them through the water, allow them to make fast turns and sudden moves in the water or initiate swimming. Webbed feet are an advantage in shallow water, where the animals sometimes move around by walking. Crocodiles have a palatal flap, a rigid tissue at the back of the mouth that blocks the entry of water. The palate has a special path from the nostril to the glottis that bypasses the mouth. The nostrils are closed during submergence.

 

Like other archosaurs, crocodilians are diapsid, although their post-temporal fenestrae are reduced. The walls of the braincase are bony but lack supratemporal and postfrontal bones. Their tongues are not free, but held in place by a membrane that limits movement; as a result, crocodiles are unable to stick out their tongues. Crocodiles have smooth skin on their bellies and sides, while their dorsal surfaces are armoured with large osteoderms. The armoured skin has scales and is thick and rugged, providing some protection. They are still able to absorb heat through this armour, as a network of small capillaries allows blood through the scales to absorb heat. The osteoderms are highly vascularised and aid in calcium balance, both to neutralize acids while the animal cannot breathe underwater and to provide calcium for eggshell formation. Crocodilian tegument have pores believed to be sensory in function, analogous to the lateral line in fishes. They are particularly seen on their upper and lower jaws. Another possibility is that they are secretory, as they produce an oily substance which appears to flush mud off.

 

Size

Size greatly varies among species, from the dwarf crocodile to the saltwater crocodile. Species of the dwarf crocodile Osteolaemus grow to an adult size of just 1.5 to 1.9 m (4.9 to 6.2 ft), whereas the saltwater crocodile can grow to sizes over 6 m (20 ft) and weigh over 1,000 kg (2,200 lb). Several other large species can reach over 5.2 m (17 ft) long and weigh over 900 kg (2,000 lb). Crocodilians show pronounced sexual dimorphism, with males growing much larger and more rapidly than females. Despite their large adult sizes, crocodiles start their lives at around 20 cm (7.9 in) long. The largest species of crocodile is the saltwater crocodile, found in eastern India, northern Australia, throughout South-east Asia, and in the surrounding waters.

 

The brain volume of two adult crocodiles was 5.6 cm3 for a spectacled caiman and 8.5 cm3 for a larger Nile crocodile.

 

The largest crocodile ever held in captivity is a saltwater–Siamese hybrid named Yai (Thai: ใหญ่, meaning big; born 10 June 1972) at the Samutprakarn Crocodile Farm and Zoo, Thailand. This animal measures 6 m (20 ft) in length and weighs 1,200 kg (2,600 lb).

 

The longest crocodile captured alive was Lolong, a saltwater crocodile which was measured at 6.17 m (20.2 ft) and weighed at 1,075 kg (2,370 lb) by a National Geographic team in Agusan del Sur Province, Philippines.

 

Teeth

Crocodiles are polyphyodonts; they are able to replace each of their 80 teeth up to 50 times in their 35- to 75-year lifespan. Next to each full-grown tooth, there is a small replacement tooth and an odontogenic stem cell in the dental lamina in standby that can be activated if required.

 

Biology and behaviour

Crocodilians are more closely related to birds and dinosaurs than to most animals classified as reptiles, the three families being included in the group Archosauria ('ruling reptiles'). Despite their prehistoric look, crocodiles are among the more biologically complex reptiles. Unlike other reptiles, a crocodile has a cerebral cortex and a four-chambered heart. Crocodilians also have the functional equivalent of a diaphragm by incorporating muscles used for aquatic locomotion into respiration. Salt glands are present in the tongues of crocodiles and they have a pore opening on the surface of the tongue, a trait that separates them from alligators. Salt glands are dysfunctional in Alligatoridae. Their function appears to be similar to that of salt glands in marine turtles. Crocodiles do not have sweat glands and release heat through their mouths. They often sleep with their mouths open and may pant like a dog. Four species of freshwater crocodile climb trees to bask in areas lacking a shoreline.

 

Senses

Crocodiles have acute senses, an evolutionary advantage that makes them successful predators. The eyes, ears and nostrils are located on top of the head, allowing the crocodile to lie low in the water, almost totally submerged and hidden from prey.

 

Vision

Crocodiles have very good night vision, and are mostly nocturnal hunters. They use the disadvantage of most prey animals' poor nocturnal vision to their advantage. The light receptors in crocodilians' eyes include cones and numerous rods, so it is assumed all crocodilians can see colours. Crocodiles have vertical-slit shaped pupils, similar to those of domestic cats. One explanation for the evolution of slit pupils is that they exclude light more effectively than a circular pupil, helping to protect the eyes during daylight. On the rear wall of the eye is a tapetum lucidum, which reflects incoming light back onto the retina, thus utilizing the small amount of light available at night to best advantage. In addition to the protection of the upper and lower eyelids, crocodiles have a nictitating membrane (sometimes called a "third eye-lid") that can be drawn over the eye from the inner corner while the lids are open. The eyeball surface is thus protected under the water while a certain degree of vision is still possible.

 

Olfaction

Crocodilian sense of smell is also very well developed, aiding them to detect prey or animal carcasses that are either on land or in water, from far away. It is possible that crocodiles use olfaction in the egg prior to hatching.

 

Chemoreception in crocodiles is especially interesting because they hunt in both terrestrial and aquatic surroundings. Crocodiles have only one olfactory chamber and the vomeronasal organ is absent in the adults indicating all olfactory perception is limited to the olfactory system. Behavioural and olfactometer experiments indicate that crocodiles detect both air-borne and water-soluble chemicals and use their olfactory system for hunting. When above water, crocodiles enhance their ability to detect volatile odorants by gular pumping, a rhythmic movement of the floor of the pharynx. Crocodiles close their nostrils when submerged, so olfaction underwater is unlikely. Underwater food detection is presumably gustatory and tactile.

 

Hearing

Crocodiles can hear well; their tympanic membranes are concealed by flat flaps that may be raised or lowered by muscles.

 

Touch

The touch sensors, concentrated in crocodile skin, can be thicker than those in human fingerprints. Crocodiles can feel the touch on their skin.

 

Cranial: The upper and lower jaws are covered with sensory pits, visible as small, black speckles on the skin, the crocodilian version of the lateral line organs seen in fish and many amphibians, though arising from a completely different origin. These pigmented nodules encase bundles of nerve fibers innervated beneath by branches of the trigeminal nerve. They respond to the slightest disturbance in surface water, detecting vibrations and small pressure changes as small as a single drop. This makes it possible for crocodiles to detect prey, danger and intruders, even in total darkness. These sense organs are known as domed pressure receptors (DPRs).

 

Post-Cranial: While alligators and caimans have DPRs only on their jaws, crocodiles have similar organs on almost every scale on their bodies. The function of the DPRs on the jaws is clear; to catch prey, but it is still not clear what the function is of the organs on the rest of the body. The receptors flatten when exposed to increased osmotic pressure, such as that experienced when swimming in sea water hyperosmotic to the body fluids. When contact between the integument and the surrounding sea water solution is blocked, crocodiles are found to lose their ability to discriminate salinities. It has been proposed that the flattening of the sensory organ in hyperosmotic sea water is sensed by the animal as "touch", but interpreted as chemical information about its surroundings. This might be why in alligators they are absent on the rest of the body.

 

Hunting and diet

Crocodiles are ambush predators, waiting for fish or land animals to come close, then rushing out to attack. Crocodiles mostly eat fish, amphibians, crustaceans, molluscs, birds, reptiles, and mammals, and they occasionally cannibalize smaller crocodiles. What a crocodile eats varies greatly with species, size and age. From the mostly fish-eating species, like the slender-snouted and freshwater crocodiles, to the larger species like the Nile crocodile and the saltwater crocodile that prey on large mammals, such as buffalo, deer and wild boar, diet shows great diversity. Diet is also greatly affected by the size and age of the individual within the same species. All young crocodiles hunt mostly invertebrates and small fish, gradually moving on to larger prey. Being ectothermic (cold-blooded) predators, they have a very slow metabolism, so they can survive long periods without food. Despite their appearance of being slow, crocodiles have a very fast strike and are top predators in their environment, and various species have been observed attacking and killing other predators such as sharks and big cats. Crocodiles are also known to be aggressive scavengers who feed upon carrion and steal from other predators. Evidence suggests that crocodiles also feed upon fruits, based on the discovery of seeds in stools and stomachs from many subjects as well as accounts of them feeding.

 

Crocodiles have the most acidic stomach of any vertebrate. They can easily digest bones, hooves and horns. The BBC TV reported that a Nile crocodile that has lurked a long time underwater to catch prey builds up a large oxygen debt. When it has caught and eaten that prey, it closes its right aortic arch and uses its left aortic arch to flush blood loaded with carbon dioxide from its muscles directly to its stomach; the resulting excess acidity in its blood supply makes it much easier for the stomach lining to secrete more stomach acid to quickly dissolve bulks of swallowed prey flesh and bone. Many large crocodilians swallow stones (called gastroliths or stomach stones), which may act as ballast to balance their bodies or assist in crushing food, similar to grit ingested by birds. Herodotus claimed that Nile crocodiles had a symbiotic relationship with certain birds, such as the Egyptian plover, which enter the crocodile's mouth and pick leeches feeding on the crocodile's blood; with no evidence of this interaction actually occurring in any crocodile species, it is most likely mythical or allegorical fiction.

 

Bite

Since they feed by grabbing and holding onto their prey, they have evolved sharp teeth for piercing and holding onto flesh, and powerful muscles to close the jaws and hold them shut. The teeth are not well-suited to tearing flesh off of large prey items as are the dentition and claws of many mammalian carnivores, the hooked bills and talons of raptorial birds, or the serrated teeth of sharks. However, this is an advantage rather than a disadvantage to the crocodile since the properties of the teeth allow it to hold onto prey with the least possibility of the prey animal escaping. Cutting teeth, combined with the exceptionally high bite force, would pass through flesh easily enough to leave an escape opportunity for prey. The jaws can bite down with immense force, by far the strongest bite of any animal. The force of a large crocodile's bite is more than 5,000 lbf (22,000 N), which was measured in a 5.5 m (18 ft) Nile crocodile, in the field; comparing to 335 lbf (1,490 N) for a Rottweiler, 800 lbf (3,600 N) for a hyena, 2,200 lbf (9,800 N) for an American alligator, and 4,095 lbf (18,220 N) for the largest confirmed great white shark.

 

A 5.2 m (17 ft) long saltwater crocodile has been confirmed as having the strongest bite force ever recorded for an animal in a laboratory setting. It was able to apply a bite force value of 3,700 lbf (16,000 N), and thus surpassed the previous record of 2,125 lbf (9,450 N) made by a 3.9 m (13 ft) long American alligator. Taking the measurements of several 5.2 m (17 ft) crocodiles as reference, the bite forces of 6-m individuals were estimated at 7,700 lbf (34,000 N). The study, led by Dr. Gregory M. Erickson, also shed light on the larger, extinct species of crocodilians. Since crocodile anatomy has changed only slightly over the last 80 million years, current data on modern crocodilians can be used to estimate the bite force of extinct species. An 11-to-12-metre (36–39 ft) Deinosuchus would apply a force of 23,100 lbf (103,000 N), nearly twice that of the latest, higher bite force estimations of Tyrannosaurus (12,814 lbf (57,000 N)). The extraordinary bite of crocodilians is a result of their anatomy. The space for the jaw muscle in the skull is very large, which is easily visible from the outside as a bulge at each side. The muscle is so stiff, it is almost as hard as bone to touch, as if it were the continuum of the skull. Another trait is that most of the muscle in a crocodile's jaw is arranged for clamping down. Despite the strong muscles to close the jaw, crocodiles have extremely small and weak muscles to open the jaw. Crocodiles can thus be subdued for study or transport by taping their jaws or holding their jaws shut with large rubber bands cut from automobile inner tubes.

 

Locomotion

Crocodiles can move quickly over short distances, even out of water. The land speed record for a crocodile is 17 km/h (11 mph) measured in a galloping Australian freshwater crocodile. Maximum speed varies between species. Some species can gallop, including Cuban crocodiles, Johnston's crocodiles, New Guinea crocodiles, African dwarf crocodiles, and even small Nile crocodiles. The fastest means by which most species can move is a "belly run", in which the body moves in a snake-like (sinusoidal) fashion, limbs splayed out to either side paddling away frantically while the tail whips to and fro. Crocodiles can reach speeds of 10–11 km/h (6–7 mph) when they "belly run", and often faster if slipping down muddy riverbanks. When a crocodile walks quickly, it holds its legs in a straighter and more upright position under its body, which is called the "high walk". This walk allows a speed of up to 5 km/h.

 

Crocodiles may possess a homing instinct. In northern Australia, three rogue saltwater crocodiles were relocated 400 km (249 mi) by helicopter, but returned to their original locations within three weeks, based on data obtained from tracking devices attached to them.

 

Longevity

Measuring crocodile age is unreliable, although several techniques are used to derive a reasonable guess. The most common method is to measure lamellar growth rings in bones and teeth—each ring corresponds to a change in growth rate which typically occurs once a year between dry and wet seasons. Bearing these inaccuracies in mind, it can be safely said that all crocodile species have an average lifespan of at least 30–40 years, and in the case of larger species an average of 60–70 years. The oldest crocodiles appear to be the largest species. C. porosus is estimated to live around 70 years on average, with limited evidence of some individuals exceeding 100 years.

 

In captivity, some individuals are claimed to have lived for over a century. A male crocodile lived to an estimated age of 110–115 years in a Russian zoo in Yekaterinburg. Named Kolya, he joined the zoo around 1913 to 1915, fully grown, after touring in an animal show, and lived until 1995.[70] A male freshwater crocodile lived to an estimated age of 120–140 years at the Australia Zoo. Known affectionately as "Mr. Freshie", he was rescued around 1970 by Bob Irwin and Steve Irwin, after being shot twice by hunters and losing an eye as a result, and lived until 2010. Crocworld Conservation Centre, in Scottburgh, South Africa, claims to have a male Nile crocodile that was born in 1900. Named Henry, the crocodile is said to have lived in Botswana along the Okavango River, according to centre director Martin Rodrigues.

 

Social behaviour and vocalization

Crocodiles are the most social of reptiles. Even though they do not form social groups, many species congregate in certain sections of rivers, tolerating each other at times of feeding and basking. Most species are not highly territorial, with the exception of the saltwater crocodile, which is a highly territorial and aggressive species: a mature, male saltwater crocodile will not tolerate any other males at any time of the year, but most other species are more flexible. There is a certain form of hierarchy in crocodiles: the largest and heaviest males are at the top, having access to the best basking site, while females are priority during a group feeding of a big kill or carcass. A good example of the hierarchy in crocodiles would be the case of the Nile crocodile. This species clearly displays all of these behaviours. Studies in this area are not thorough, however, and many species are yet to be studied in greater detail. Mugger crocodiles are also known to show toleration in group feedings and tend to congregate in certain areas. However, males of all species are aggressive towards each other during mating season, to gain access to females.

 

Crocodiles are also the most vocal of all reptiles, producing a wide variety of sounds during various situations and conditions, depending on species, age, size and sex. Depending on the context, some species can communicate over 20 different messages through vocalizations alone. Some of these vocalizations are made during social communication, especially during territorial displays towards the same sex and courtship with the opposite sex; the common concern being reproduction. Therefore most conspecific vocalization is made during the breeding season, with the exception being year-round territorial behaviour in some species and quarrels during feeding. Crocodiles also produce different distress calls and in aggressive displays to their own kind and other animals; notably other predators during interspecific predatory confrontations over carcasses and terrestrial kills.

 

Specific vocalisations include —

Chirp: When about to hatch, the young make a "peeping" noise, which encourages the female to excavate the nest. The female then gathers the hatchlings in her mouth and transports them to the water, where they remain in a group for several months, protected by the female[76]

Distress call: A high-pitched call used mostly by younger animals to alert other crocodiles to imminent danger or an animal being attacked.

Threat call: A hissing sound that has also been described as a coughing noise.

Hatching call: Emitted by a female when breeding to alert other crocodiles that she has laid eggs in her nest.

Bellowing: Male crocodiles are especially vociferous. Bellowing choruses occur most often in the spring when breeding groups congregate, but can occur at any time of year. To bellow, males noticeably inflate as they raise the tail and head out of water, slowly waving the tail back and forth. They then puff out the throat and with a closed mouth, begin to vibrate air. Just before bellowing, males project an infrasonic signal at about 10 Hz through the water, which vibrates the ground and nearby objects. These low-frequency vibrations travel great distances through both air and water to advertise the male's presence and are so powerful they result in the water's appearing to "dance".

 

Reproduction

Crocodiles lay eggs, which are laid in either holes or mound nests, depending on species. A hole nest is usually excavated in sand and a mound nest is usually constructed out of vegetation. Nesting periods range from a few weeks up to six months. Courtship takes place in a series of behavioural interactions that include a variety of snout rubbing and submissive display that can take a long time. Mating always takes place in water, where the pair can be observed mating several times. Females can build or dig several trial nests which appear incomplete and abandoned later. Egg-laying usually takes place at night and about 30–40 minutes. Females are highly protective of their nests and young. The eggs are hard shelled, but translucent at the time of egg-laying. Depending on the species of crocodile, 7 to 95 eggs are laid. Crocodile embryos do not have sex chromosomes, and unlike humans, sex is not determined genetically. Sex is determined by temperature, where at 30 °C (86 °F) or less most hatchlings are females and at 31 °C (88 °F), offspring are of both sexes. A temperature of 32 to 33 °C (90 to 91 °F) gives mostly males whereas above 33 °C (91 °F) in some species continues to give males, but in other species resulting in females, which are sometimes called high-temperature females. Temperature also affects growth and survival rate of the young, which may explain the sexual dimorphism in crocodiles. The average incubation period is around 80 days, and also is dependent on temperature and species that usually ranges from 65 to 95 days. The eggshell structure is very conservative through evolution but there are enough changes to tell different species apart by their eggshell microstructure. Scutes may play a role in calcium storage for eggshell formation.

 

At the time of hatching, the young start calling within the eggs. They have an egg-tooth at the tip of their snouts, which is developed from the skin, and that helps them pierce out of the shell. Hearing the calls, the female usually excavates the nest and sometimes takes the unhatched eggs in her mouth, slowly rolling the eggs to help the process. The young is usually carried to the water in the mouth. She would then introduce her hatchlings to the water and even feed them. The mother would then take care of her young for over a year before the next mating season. In the absence of the mother crocodile, the father would act in her place to take care of the young. However, even with a sophisticated parental nurturing, young crocodiles have a very high mortality rate due to their vulnerability to predation. A group of hatchlings is called a pod or crèche and may be protected for months.

 

Cognition

Crocodiles possess some advanced cognitive abilities. They can observe and use patterns of prey behaviour, such as when prey come to the river to drink at the same time each day. Vladimir Dinets of the University of Tennessee, observed that crocodiles use twigs as bait for birds looking for nesting material. They place sticks on their snouts and partly submerge themselves. When the birds swooped in to get the sticks, the crocodiles then catch the birds. Crocodiles only do this in spring nesting seasons of the birds, when there is high demand for sticks to be used for building nests. Vladimir also discovered other similar observations from various scientists, some dating back to the 19th century. Aside from using sticks, crocodiles are also capable of cooperative hunting. Large numbers of crocodiles swim in circles to trap fish and take turns snatching them. In hunting larger prey, crocodiles swarm in, with one holding the prey down as the others rip it apart.

 

According to a 2015 study, crocodiles engage in all three main types of play behaviour recorded in animals: locomotor play, play with objects and social play. Play with objects is reported most often, but locomotor play such as repeatedly sliding down slopes, and social play such as riding on the backs of other crocodiles is also reported. This behaviour was exhibited with conspecifics and mammals and is apparently not uncommon, though has been difficult to observe and interpret in the past due to obvious dangers of interacting with large carnivores.

 

Taxonomy and phylogeny

See also: List of crocodilians

Crocodylidae is cladistically defined as a crown group composed of the last common ancestor of the Nile crocodile (Crocodylus niloticus), the Dwarf crocodile (Osteolaemus tetraspis), and all of its descendants. It contains two subfamilies: Crocodylinae and Osteolaeminae. Crocodylinae contains 13-14 living species, as well as 6 extinct species. Osteolaeminae was named by Christopher Brochu in 2003 as a subfamily of Crocodylidae separate from Crocodylinae and contains the two extant genera Osteolaemus and Mecistops, along with several extinct genera. The number of extant species within Osteolaeminae is currently in question.

Relationship with humans

Danger to humans

Main article: Crocodile attacks

The larger species of crocodiles are very dangerous to humans, mainly because of their ability to strike before the person can react. The saltwater crocodile and Nile crocodile are the most dangerous, killing hundreds of people each year in parts of Southeast Asia and Africa. The mugger crocodile and American crocodile are also dangerous to humans.

 

Crocodile products

Further information: Crocodile farm and Crocodile skin

Crocodiles are protected in many parts of the world, but are also farmed commercially. Their hides are tanned and used to make leather goods such as shoes and handbags; crocodile meat is also considered a delicacy. The most commonly farmed species are the saltwater and Nile crocodiles, while a hybrid of the saltwater and the rare Siamese crocodile is also bred in Asian farms. Farming has resulted in an increase in the saltwater crocodile population in Australia, as eggs are usually harvested from the wild, so landowners have an incentive to conserve their habitat. Crocodile leather can be made into goods such as wallets, briefcases, purses, handbags, belts, hats, and shoes. Crocodile oil has been used for various purposes. Crocodiles were eaten by Vietnamese while they were taboo and off limits for Chinese. Vietnamese women who married Chinese men adopted the Chinese taboo.

 

Crocodile meat is consumed in some countries, such as Australia, Ethiopia, Thailand, South Africa, China, and Cuba (in pickled form). It is also occasionally eaten as an "exotic" delicacy in the western world. Cuts of meat include backstrap and tail fillet.

 

Due to high demand for crocodile products, TRAFFIC states that 1,418,487 Nile Crocodile skins were exported from Africa between 2006 and 2015.

 

Crocodile hunting and conservation

Aboriginal Australians harvested eggs and hunted crocodiles in a sustainable way for many thousands of years. The Brinkin people (aka Marrithiyal) of the Daly River in the Northern Territory (NT) used harpoons and bamboo, and even their own hands to capture crocodiles for food. After settlement of northern Australia, in the late-19th and early 20th centuries, non-Indigenous people killed individual crocodiles, mostly by locals to protect the population, or novelty-seeking visitors, or just opportunistically, so numbers were not noticeably reduced. From the 1930s, commercial hunting began, with Aboriginal people often employed to kill the crocodiles using traditional methods. From the 1940s to the 1960s, hunting began on a larger scale using .303 rifles. They were hunted for leather, with the skins shipped to plants in capital cities. Western Australia banned hunting freshwater crocodiles in 1962 and saltwater crocodiles in 1970, while NT bans were brought in 1964 and 1971; Queensland did not pass such legislation. The federal government later banned the export of crocodile skins, which brought commercial hunting to an end in Queensland. They have been a protected species since the 1970s, when numbers were down to approximately 3,000 in the NT at the lowest estimate. In 2021, after several attacks on humans by the "salties" and an estimated population of around 200,000 had been reached, Queensland politician Bob Katter called for the reintroduction of hunting.

 

In religion and mythology

Further information: Crocodilia § Cultural_depictions

Crocodiles have appeared in various forms in religions across the world. Ancient Egypt had Sobek, the crocodile-headed god, with his cult-city Crocodilopolis, as well as Taweret, the goddess of childbirth and fertility, with the back and tail of a crocodile. The Jukun shrine in the Wukari Federation, Nigeria is dedicated to crocodiles in thanks for their aid during migration. In Madagascar various peoples such as the Sakalava and Antandroy see crocodiles as ancestor spirits and under local fady often offer them food; in the case of the latter at least a crocodile features prominently as an ancestor deity.

 

Crocodiles appear in different forms in Hinduism. Varuna, a Vedic and Hindu god, rides a part-crocodile makara; his consort Varuni rides a crocodile.[88] Similarly the goddess personifications of the Ganga and Yamuna rivers are often depicted as riding crocodiles. Also in India, in Goa, crocodile worship is practised, including the annual Mannge Thapnee ceremony.

 

Sikh warriors known as nihang also have connections with crocodiles. Nihang may come from the Persian word for a mythical sea creature (Persian: نهنگ). The term owes its origin to Mughal historians, who compared the ferocity of the Akali with that of crocodiles. The meaning of Akali in Sikhism however, is the immortal army of Akal (god).

 

In Latin America, Cipactli was the giant earth crocodile of the Aztec and other Nahua peoples.

  

Fighting shark and crocodile, the emblem of Surabaya

The name of Surabaya,Indonesia, is locally believed to be derived from the words "suro" (shark) and "boyo" (crocodile), two creatures which, in a local myth, fought each other in order to gain the title of "the strongest and most powerful animal" in the area. It was said that the two powerful animals agreed for a truce and set boundaries; that the shark's domain would be in the sea while the crocodile's domain would be on the land. However one day the shark swam into the river estuary to hunt, this angered the crocodile, who declared it his territory. The Shark argued that the river was a water-realm which meant that it was shark territory, while the crocodile argued that the river flowed deep inland, so it was therefore crocodile territory. A ferocious fight resumed as the two animals bit each other. Finally the shark was badly bitten and fled to the open sea, and the crocodile finally ruled the estuarine area that today is the city. Another source alludes to a Jayabaya prophecy—a 12th-century psychic king of Kediri Kingdom—as he foresaw a fight between a giant white shark and a giant white crocodile taking place in the area, which is sometimes interpreted as a foretelling of the Mongol invasion of Java, a major conflict between the forces of the Kublai Khan, Mongol ruler of China, and those of Raden Wijaya's Majapahit in 1293. The two animals are now used as the city's symbol, with the two facing and circling each other, as depicted in a statue appropriately located near the entrance to the city zoo (see photo on the Surabaya page).[citation needed]

 

In language and as symbols

Main article: Crocodile tears

The term "crocodile tears" (and equivalents in other languages) refers to a false, insincere display of emotion, such as a hypocrite crying fake tears of grief. It is derived from an ancient anecdote that crocodiles weep in order to lure their prey, or that they cry for the victims they are eating, first told in the Bibliotheca by Photios I of Constantinople. The story is repeated in bestiaries such as De bestiis et aliis rebus. This tale was first spread widely in English in the stories of the Travels of Sir John Mandeville in the 14th century, and appears in several of Shakespeare's plays. In fact, crocodiles can and do generate tears, but they do not actually cry.

 

In the UK, a row of schoolchildren walking in pairs, or two by two is known as "crocodile".

 

Fashion logos

The French clothing company Lacoste features a crocodile in its logo. The American shoe company Crocs also uses this imagery in its logo.

Jahangirnagar University, Savar

Socratic man believes that all virtue is cognition, and that all that is needed to do what is right is to know what is right. This does not hold for Mosaic man who is informed with the profound experience that cognition is never enough, that the deepest part of him must be seized by the teachings, that for realization to take place his elemental totality must submit to the spirit as clay to the potter.

Often used as a representation of the mind or soul, Psyche has been adopted as a symbol of the field of psychology - see the figure in the top left of the British Psychological Society's website at www.bps.org.uk/ for example. So this fabulous statue means more to me as a psychologist than simply a Greek myth, rich though that story may be.

 

At various times in its relatively brief history psychology has been in danger of becoming irrelevant through its attachment to a dull orthodoxy that had little to do with the greater issues of human life. This happened during the 1940s and 50s when behaviourism and psychoanalysis were the dominant influences, during the 1970s and 80s with cognitive science, and potentially today with the rapidly increasing influence of neuropsychology.

 

During the 1950s psychology was revived through the influence of humanistic psychology, which brought the whole person back into consideration. More recently, positive psychology animated a field in danger of being stifled through an excess of cognition. Will the recent and rapid rise of interest in mindfulness breathe life into a psychology which seems overly impressed by the reductionism of neuroscience?
