Just got back from the Maasai Mara and the annual migration was in full force. With ample food available this Lion pair were busy mating on the open savannah plains of Mara.

Most lionesses reproduce by the time they are four years of age. Lions do not mate at a specific time of year and the females are polyestrous. Like those of other cats, the male lion's penis has spines that point backward. During withdrawal of the penis, the spines rake the walls of the female's vagina, which may cause ovulation.

During withdrawal of the penis, the spines rake the walls of the female's vagina, which may cause ovulation. A lioness may mate with more than one male when she is in heat. They normally mate after every 15-20 minutes for 2-3 days whilst on their honeymoon. The average gestation period is around 110 days; the female gives birth to a litter of between one and four cubs in a secluded den, which may be a thicket, a reed-bed, a cave, or some other sheltered area, usually away from the pride.

About one month ago I decided to do a home insemination...... anyone who know me knows How baby crazy I have been the past few months but little do they know I have been trying and trying to have a baby for months now omg it’s been rocky but I made a very big decision when I decided to do a home insemination and just to think the sperm of the man that I’m using I have never even laid eyes on I have no idea who he is like all I know is what in this piece of paper but anyways so awesome early last night I took a ovulating test to see if I was ovulating and I was so I decided to go ahead and proceed with the insemination but I’m sharing this with y’all because this morning I woke up sick as hell and it started around 4am home I’m so excited once I got myself together I went get to get some test still in my pjs and all (test results coming soon)

Female cheetah with her offspring out on the grasslands.

 

The cheetah /ˈtʃiːtə/ (Acinonyx jubatus) is a large cat of the subfamily Felinae that occurs in Southern, North and East Africa, and a few localities in Iran. The species is IUCN Red Listed as vulnerable, as it suffered a substantial decline in its historic range in the 20th century due to habitat loss, poaching, illegal pet trade, and conflict with humans. By 2016, the global cheetah population has been estimated at approximately 7,100 individuals in the wild. Several African countries have taken steps to improve cheetah conservation measures. It is the fastest land animal.

 

Cheetahs are active mainly during the day, with hunting their major activity. Adult males are sociable despite their territoriality, forming groups called coalitions. Females are not territorial; they may be solitary or live with their offspring in home ranges. Carnivores, cheetah mainly prey upon antelopes and gazelles. They will stalk their prey to within 100–300 m (330–980 ft), charge towards it and kill it by tripping it during the chase and biting its throat to suffocate it to death. Cheetahs can reach speeds of 112 km/h (70 mph) in short bursts, but this is disputed by more recent measurements. The average speed of cheetahs is about 64 km/h (40 mph). Cheetahs are induced ovulators, breeding throughout the year. Gestation is nearly three months long, resulting in a litter of typically three to five cubs (the number can vary from one to eight). Weaning occurs at six months; siblings tend to stay together for some time. Cheetah cubs face higher mortality than most other mammals, especially in the Serengeti region. Cheetahs inhabit a variety of habitats – dry forests, scrub forests and savannahs. -Wikipedia

Grazing alpacas is not what you expect to see in northern Germany...

 

Along with camels and llamas, alpacas are classified as camelids. Of the various camelid species, the alpaca and vicuña are the most valuable fiber-bearing animals: the alpaca because of the quality and quantity of its fiber, and the vicuña because of the softness, fineness and quality of its coat.

 

Alpacas are too small to be used as pack animals. Instead, they are bred exclusively for their fiber and meat. Alpaca meat was once considered a delicacy by Andean inhabitants.

(Wikipedia)

 

And a curious factoid from the same source: "Females are induced ovulators; the act of mating and the presence of semen causes them to ovulate." Wow.

Apparently it is a thing , you can buy double yoked eggs. Who knew?

 

"To understand the rich miracle of the double yolker, one must understand the biological process of egg-making. “It takes 25 hours to make one egg, When a hen is hatched, they come into the world with a certain number of ova—it’s like a bunch of grapes that hangs from the backbone.” There comes a time in every young hen’s life when she is mature enough to lay eggs, and when that time comes, the ova grow one at a time until it’s the size of a yolk. Then it breaks away from the ovary, traveling through the oviduct, leaving the ovaries to the outside world. As the yolk moves through the oviduct, glands secrete the albumen, a.k.a. the egg white, and the substance to form the shell, and then, lo and behold, an egg is laid.

 

...But the working theory is that they are forged when ovulation occurs too rapidly or when one yolk catches up with another slow-moving yolk in a hen’s oviduct.

 

In all likelihood, if you find yourself with a double yolker, it came from an egg-laying pullet, a young hen, specifically under a year old." - Gail Damerow

As I mentioned in the first photo I posted from our trip to Africa in June/July of this year, we only saw two leopards the entire trip. Disappointing and unusual...but we saw many more cheetahs than we normally see. This is a photo of one of the female cheetahs we saw with 3 juvenile offspring accompanying her. In this case, she's relaxed staring off into the distance...perhaps day dreaming of slow antelopes. We were staying at a tented camp in the Serengeti, Tanzania and were delighted to see so many of these beautiful, graceful animals.

By 2016, the global cheetah population has been estimated at approximately 7,100 individuals in the wild. Several African countries have taken steps to improve cheetah conservation measures.

 

It is the fastest land animal. The only extant member of the genus Acinonyx, the cheetah was formally described by Johann Christian Daniel von Schreber in 1775. The cheetah is characterised by a slender body, deep chest, spotted coat, small rounded head, black tear-like streaks on the face, long thin legs and long spotted tail. Its lightly built, slender form is in sharp contrast with the robust build of the big cats, making it more similar to the cougar. The cheetah reaches nearly 70 to 90 cm (28 to 35 in) at the shoulder, and weighs 21–72 kg (46–159 lb). Though taller than the leopard, it is notably smaller than the lion. Typically yellowish tan or rufous to greyish white, the coat is uniformly covered with nearly 2,000 solid black spots.

 

Cheetahs are active mainly during the day, with hunting their major activity. Adult males are sociable despite their territoriality, forming groups called coalitions. Females are not territorial; they may be solitary or live with their offspring in home ranges. Carnivores, cheetah mainly prey upon antelopes and gazelles.

Weaning occurs at six months; siblings tend to stay together for some time. Cheetah cubs face higher mortality than most other mammals, especially in the Serengeti region. Cheetahs inhabit a variety of habitats – dry forests, scrub forests and savannahs.

 

Because of its prowess at hunting, the cheetah was tamed and used to kill game at hunts in the past. The animal has been widely depicted in art, literature, advertising and animation.

 

The cheetah's closest relatives are the cougar (Puma concolor) and the jaguarundi (Herpailurus yagouaroundi).[These three species together form the Puma lineage, one of the eight lineages of Felidae. The sister group of the Puma lineage is a clade of smaller Old World cats that includes the genera Felis, Otocolobus and Prionailurus.

 

Although the cheetah is an African cat, molecular evidence indicates that the three species of the Puma lineage evolved in North America two to three million years ago, where they possibly had a common ancestor during the Miocene. They possibly diverged from this ancestor 8.25 million years ago. The cheetah diverged from the puma and the jaguarundi around 6.7 million years ago. A genome study suggests that cheetahs experienced two genetic bottlenecks in their history, the first about 100,000 years ago and the second about 12,000 years ago, greatly lowering their genetic variability. These bottlenecks may have been associated with migrations across Asia and into Africa (with the current African population founded about 12,000 years ago), and/or with a depletion of prey species at the end of the Pleistocene.

Pair of mating lions....Maasai Mara, Kenya

 

"In the wild, lions usually breed no more than once in two years. Females are receptive to mating for three or four days within a widely variable reproductive cycle. During this time a pair generally mates every 20–30 minutes, with up to 50 copulations per 24 hours. Such extended copulation not only stimulates ovulation in the female but also secures paternity for the male by excluding other males. The gestation period is about 108 days, and the litter size varies from one to six cubs, two to four being usual."

Taken the day we went to the Corn Maze. Sorry I haven't visited your guys' streams. I've been feeling so horrible these past 2 days. Last night was the worst. I could not sleep, I had the most horrible headache in my LIFE, my kidneys hurt, my liver ached a bit, my body ached, I felt weak to my knees... It was so weird. I actually went to bed at 7pm last night. But I woke up every hour thirsty for water. I think it's the new medication I was put on last week. I quit taking it today. NO MORE. I tried to hang in there but I just can't do it. I feel a bit like a failure since this medication was supposed to help me ovulate to try to get pregnant again but when it compromises my health, I don't think it's worth it. You know?

 

I feel blessed to have had a daughter. What more could God have blessed me with?

 

I have these little pumpkins/squash in the backyard. I'm thinking of carving them for her. But they're really little... I'm wondering how hard that's going to be? I'll have to go buy a knife specially for that. I love how they're so small and fit right into her hands. LOL So cute... Hope everyone has a wonderful Thursday. I sure hope I do. I do feel a bit better today though, thank GOD.

The European polecat (Mustela putorius), also known as the common polecat, black or forest polecat, European ferret, wild ferret, or simply polecat, is a species of mustelid native to western Eurasia and North Africa. It is of a generally dark brown color, with a pale underbelly and a dark mask across the face. Occasionally, color mutations including albinos, leucists, amelanists and erythrists occur. It has a shorter, more compact body than other Mustela species, a more powerfully built skull and dentition, is less agile, and is well known for having the characteristic ability to secrete a particularly foul-smelling liquid to mark its territory.

 

It is much less territorial than other mustelids, with animals of the same sex frequently sharing home ranges. Like other mustelids, the European polecat is polygamous, with pregnancy occurring after mating, with no induced ovulation. It usually gives birth in early summer to litters consisting of five to 10 kits, which become independent at the age of two to three months. The European polecat feeds on small rodents, birds, amphibians and reptiles. It occasionally cripples its prey by piercing its brain with its teeth and stores it, still living, in its burrow for future consumption.

 

The European polecat originated in Western Europe during the Middle Pleistocene, with its closest living relatives being the steppe polecat, the black-footed ferret and the European mink. With the two former species, it can produce fertile offspring, though hybrids between it and the latter species tend to be sterile, and are distinguished from their parent species by their larger size and more valuable pelts.

 

The European polecat is the sole ancestor of the ferret, which was domesticated more than 2,000 years ago for the purpose of hunting vermin. The species has otherwise been historically viewed negatively by humans. In Britain especially, the polecat was persecuted by gamekeepers, and became synonymous with promiscuity in early English literature. During modern times, the polecat is still scantly represented in popular culture when compared to other rare British mammals, and misunderstandings of its behavior still persist in some rural areas.

 

The dimensions of the European polecat vary greatly. The species does not conform to Bergmann's rule, with the pattern of size variation seeming to follow a trend of size increase along an east–west axis. Males measure 350–460 mm in body length and females are 290–394 mm. The tail measures 115–167 mm in males and 84–150 mm in females. Adult males in middle Europe weigh 1,000-1,500 grams and females 650-815 grams. Gigantism is known among polecats, but specimens exhibiting this are likely the products of polecat-mink hybridization.

 

The European polecat is present in all of France's territories, excepting Corsica, and has been in a state of decline for several decades. Nevertheless, it is listed as Least Concern on France's Red Data Book. The European polecat is rare in numerous regions or départements. In the Rhone-Alps region, its population has undergone a sizeable decline since the 1990s, largely as a consequence of poisoning campaigns against muskrats. A 1999 study on the decline of polecats in this region indicated the species has little chance of surviving there. Elsewhere, it is considered either rare or sporadic in 22 districts and absent or extirpated in 22 others. In Drôme, for example, polecat populations have been decreasing since 1975, and have disappeared in 27 communes in Isère. Its numbers are declining in Morvan and Ariège, and is thinly distributed in Brittany. Although present in Aquitaine, its numbers have been dropping since the 1950s, and is very rare in the mountain regions. In Normandy, the speed of the polecat's decline has somewhat decreased. In the alpine départements, its range is limited by altitude, as the species relies on more Mediterranean climates to thrive. It is, however, especially abundant in the irrigated Crau, but is absent on the eastern part of the area, apparently being restricted by the valleys of the Durance and Rhone Rivers. The largest populations occur in Northern France: Pas de Calais, Central France; Alsace, Lorraine and the areas of the Loire with the Vendée, which holds the largest record of polecat observations. It is common in all the départements of Champagne-Ardenne.

The male often bites the female’s neck to maintain control and possibly stimulate ovulation.

Wang's partner of 29 years, Geebee, died this year making him the last polar bear in Africa. Wang has been in mourning ever since.

 

Joburg Zoo said it will not be replace Geebee, a decision influenced by Johannesburg’s weather conditions.

 

“Despite polar bears being highly adaptive, Johannesburg’s climatic conditions are not ideal for breeding purposes. Polar bears adapt really well to different conditions, however, will not breed in warmer climates as they require low temperatures to ovulate, so from a conservation perspective, replacing Geebee with another polar bear does not make sense,” said the zoo.

Cheetahs are induced ovulators, breeding throughout the year. Gestation is nearly three months long, resulting in a litter of typically three to five cubs (the number can vary from one to eight). Weaning occurs at six months; siblings tend to stay together for some time. Cheetah cubs face higher mortality than most other mammals, especially in the Serengeti region. Cheetahs inhabit a variety of habitats – dry forests, scrub forests and savannahs.

 

Because of its prowess at hunting, the cheetah was tamed and used to kill game at hunts in the past. The animal has been widely depicted in art, literature, advertising and animation.

 

The cheetah's closest relatives are the cougar (Puma concolor) and the jaguarundi (Herpailurus yagouaroundi).[These three species together form the Puma lineage, one of the eight lineages of Felidae. The sister group of the Puma lineage is a clade of smaller Old World cats that includes the genera Felis, Otocolobus and Prionailurus.

 

Although the cheetah is an African cat, molecular evidence indicates that the three species of the Puma lineage evolved in North America two to three million years ago, where they possibly had a common ancestor during the Miocene. They possibly diverged from this ancestor 8.25 million years ago. The cheetah diverged from the puma and the jaguarundi around 6.7 million years ago. A genome study suggests that cheetahs experienced two genetic bottlenecks in their history, the first about 100,000 years ago and the second about 12,000 years ago, greatly lowering their genetic variability. These bottlenecks may have been associated with migrations across Asia and into Africa (with the current African population founded about 12,000 years ago), and/or with a depletion of prey species at the end of the Pleistocene.

As I mentioned in the first photo I posted from our trip to Africa in June/July of 2023, we only saw two leopards the entire trip...disappointing and unusual...but we saw *many* more cheetahs than we normally see. This is a photo of 3 juvenile offspring accompanying their mother in the Serengeti. Our safari vehicle moved to position itself in their anticipated path and it worked out well. In this case, the 3 siblings spent some time on a grassy mound gazing into the distance before the middle one decided to move forward. Please make sure to click twice to see the largest size so you can get a close look at the eyes of the two looking in the direction of the camera. Such beautiful animals!

From Wikipedia: The cheetah (Acinonyx jubatus) is a large cat of the subfamily Felinae that occurs in Southern, North and East Africa and and a few localities in Iran. The species is IUCN Red Listed as vulnerable, as it suffered a substantial decline in its historic range in the 20th century due to habitat loss, poaching, illegal pet trade, and conflict with humans. By 2016, the global cheetah population has been estimated at approximately 7,100 individuals in the wild. Several African countries have taken steps to improve cheetah conservation measures.

 

It is the fastest land animal. The only extant member of the genus Acinonyx, the cheetah was formally described by Johann Christian Daniel von Schreber in 1775. The cheetah is characterised by a slender body, deep chest, spotted coat, small rounded head, black tear-like streaks on the face, long thin legs and long spotted tail. Its lightly built, slender form is in sharp contrast with the robust build of the big cats, making it more similar to the cougar. The cheetah reaches nearly 70 to 90 cm (28 to 35 in) at the shoulder, and weighs 21–72 kg (46–159 lb). Though taller than the leopard, it is notably smaller than the lion. Typically yellowish tan or rufous to greyish white, the coat is uniformly covered with nearly 2,000 solid black spots.

 

Cheetahs are active mainly during the day, with hunting their major activity. Adult males are sociable despite their territoriality, forming groups called coalitions. Females are not territorial; they may be solitary or live with their offspring in home ranges. Carnivores, cheetah mainly prey upon antelopes and gazelles. They will stalk their prey to within 100–300 m (330–980 ft), charge towards it and kill it by tripping it during the chase and biting its throat to suffocate it to death. Cheetahs can reach speeds of 112 km/h (70 mph) in short bursts, but this is disputed by more recent measurements. The average speed of cheetahs is about 64 km/h (40 mph).

Victoria gave birth to Edward on July 28, 2019 at the Nikita Kahn Rhino Rescue Center, following hormone-induced ovulation and artificial insemination.

... further research could clarify whether women have evolved special adaptations to signal estrus through such cues—or whether the cues are “leaking” to sexually discriminating men as unselected side effects of cycle physiology. Distinguishing between estrous “signals” and “leaked cues” may be difficult in practice because estrous females (seeking extra-pair copulations with good-gene males) and extra-pair males (offering good genes) may have shared interests in female fertility signals being “conspiratorial whispers” that are accurate but inconspicuous (Pagel, 1994). In serially monogamous species such as ours, women's estrous signals may have evolved an extra degree of plausible deniability and tactical flexibility to maximize women's ability to attract high-quality extra-pair partners just before ovulation, while minimizing the primary partner's mate guarding and sexual jealousy. For these reasons, we suspect that human estrous cues are likely to be very flexible and stealthy—subtle behavioral signals that fly below the radar of conscious intention or perception, adaptively hugging the cost–benefit contours of opportunistic infidelity.

Playful Southern White Rhino Calf at the San Diego Zoo Safari Park Receives Name: Future

Name Celebrates the Hope She Brings to Future Rhino Conservation Worldwide

 

A 19-day-old southern white rhino calf at the San Diego Zoo Safari Park ventured into the sunshine this morning (Monday, Dec. 9), enjoying a reprieve from the recent rains and exploring the mud puddles the rains left behind. While mom Amani enjoyed her breakfast, the little calf explored the maternity yard, running, splashing and rolling in the mud. Wallowing in mud is a natural behavior for rhinos. They coat themselves with a thick layer of mud that helps act as a sunscreen and bug repellent, and helps to keep them cool.

The playful calf was recently given the name Future in honor of a strong female leader and past president of a privately held family foundation, which has generously supported reproductive research since 1979 and the Nikita Kahn Rhino Rescue Center, in recent years. Future is San Diego Zoo Global’s 100th southern white rhino born at the Safari Park, and she is only the second calf in North America to be born following hormone-induced ovulation and artificial insemination. Her name celebrates these monumental milestones—and the hope she brings to the future of rhino conservation worldwide.

The size (2cm in length) and anatomic features suggest development equivalent to a nine-week pregnancy (or seven weeks post ovulation). In obstetrics, pregnancy is dated from the first day of the last menstrual period, which is about two weeks prior to the ovulation that resulted in the pregnancy

Letter found buried near Passchendaele, dated August 20th, 1917.

 

"Dearest Clementine,

 

Guess who has returned?

I have created a monster, because nobody wants to see Marshall anymore.

They want Shady, I am chopped liver. Well, if you want Shady, then this is what I will give you:

a little bit of weed mixed with some hard liquor; some vodka that will jump start my heart quicker than a shot when I get shocked at the hospital by the doctor, when I am not cooperating... when I am rocking the table while he is operating.

 

Hark, you waited this long to stop debating, because I am back, I am on the rag and ovulating. I know have a job Ms. Cheney, but your husband's heart problem is complicating.

So the Federal Communications Commission will not let me be, or let me be me, so let me see.

They tried to shut me down on Music Television, but it feels so empty without me.

 

I fear we will not survive the night.

 

Real name, no gimmicks,

Obie Trice."

 

Immature Boa Constrictor (Boa constrictor) flourishes in a wide variety of environmental conditions, from tropical rainforests to arid semidesert country.[28] However, it prefers to live in rainforest due to the humidity and temperature, natural cover from predators, and vast amount of potential prey. It is commonly found in or along rivers and streams, as it is a very capable swimmer. Boa constrictors also occupy the burrows of medium-sized mammals, where they can hide from potential predators.

 

Boa constrictors generally live on their own and do not interact with any other snakes unless they want to mate. They are nocturnal, but they may bask during the day when night-time temperatures are too low. As semi-arboreal snakes, young boa constrictors may climb into trees and shrubs to forage; however, they become mostly terrestrial as they become older and heavier. Boa constrictors strike when they perceive a threat. Their bite can be painful, especially from large snakes, but is rarely dangerous to humans. Specimens from Central America are more irascible, hissing loudly and striking repeatedly when disturbed, while those from South America tame down more readily. Like all snakes, boa constrictors in a shed cycle are more unpredictable, because the substance that lubricates between the old skin and the new makes their eyes appear milky, blue, or opaque so that the snake cannot see very well, causing it to be more defensive than it might otherwise be.

 

Their prey includes a wide variety of small to medium-sized mammals and birds. The bulk of their diet consists of rodents (such as squirrels, mice, rats and agoutis), but frogs, larger lizards (such as ameivas, iguanas and tegus) and mammals as big as monkeys, marsupials (opossums), armadillos, wild pigs, young brocket deer and ocelots are also reported to have been consumed. Domestic animals such as dogs, cats, rabbits, ducks and chickens are frequently consumed. Young boa constrictors eat small mice, birds, bats, lizards, and amphibians. The size of the prey item increases as they get older and larger. Once a boa constrictor has caught its prey, it will wrap its coils around the animal and constrict it until it dies by asphyxiation. The boa's powerful muscles allow it to exert a great deal of pressure, and the prey is typically killed within a few minutes.

 

Boa constrictors are ambush predators, so they often lie in wait for an appropriate prey to come along, then they attack a moment before the prey can escape. However, they have also been known to actively hunt, particularly in regions with a low concentration of suitable prey, and this behaviour generally occurs at night. The boa first strikes at the prey, grabbing it with its teeth; it then proceeds to constrict the prey until death before consuming it whole. Unconsciousness and death likely result from shutting off vital blood flow to the heart and brain, causing asphyxiation, rather than suffocation as was previously believed; constriction can interfere with blood flow and overwhelm the prey's usual blood pressure and circulation. This would lead to unconsciousness and death very quickly. Their teeth also help force the animal down the throat while muscles then move it toward the stomach. It takes the snake about 4–6 days to fully digest the food, depending on the size of the prey and the local temperature. After this, the snake may not eat for a week to several months, due to its slow metabolism.

 

Boa constrictors are viviparous, giving birth to live young. They generally breed in the dry season—between April and August—and are polygynous; thus, males may mate with multiple females. Half of all females breed in a given year, and a larger percentage of males actively attempt to locate a mate. Due to their polygynous nature, many of these males will be unsuccessful. As such, female boas in inadequate physical condition are unlikely to attempt to mate, or to produce viable young if they do mate. Reproduction in boas is almost exclusively sexual. In 2010, a boa constrictor was shown to have reproduced asexually via parthenogenesis.

 

During the breeding season, the female boa constrictor emits pheromones from her cloaca to attract males, which may then wrestle to select one to breed with her. During breeding, the male curls his tail around the female's and the hemipenes (or male reproductive organs) are inserted. Copulation can last from a few minutes to several hours and may occur several times over a period of a few weeks. After this period, ovulation may not occur immediately, but the female can hold the sperm inside her for up to one year. When the female ovulates, a midbody swell can be noticed that appears similar to the snake having eaten a large meal. The female then sheds two to three weeks after ovulation, in what is known as a post-ovulation shed which lasts another 2–3 weeks, which is longer than a normal shed. The gestation period, which is counted from the post ovulation shed, is around 100–120 days. The female then gives birth to young that average 15–20 in (38–51 cm) in length. The litter size varies between females but can be between 10 and 65 young, with an average of 25, although some of the young may be stillborn or unfertilized eggs known as "slugs". The young are independent at birth and grow rapidly for the first few years, shedding regularly (once every one to two months). At 3–4 years, boa constrictors become sexually mature and reach the adult size of 6–10 feet (1.8–3.0 m), although they continue to grow at a slow rate for the rest of their lives. At this point, they shed less frequently, about every 2–4 months.

This was one of three jackrabbits nibbling on the grasses, late in the afternoon

 

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

From Wikipedia: The black-tailed jackrabbit (Lepus californicus), also known as the American desert hare, is a common hare of the western United States and Mexico, where it is found at elevations from sea level up to 10,000 ft (3,000 m). Reaching a length around 2 ft (61 cm), and a weight from 3 to 6 lb (1.4 to 2.7 kg), the black-tailed jackrabbit is the one of the largest North American hares. Black-tailed jackrabbits occupy mixed shrub-grassland terrains. Their breeding depends on the location; it typically peaks in spring, but may continue all year round in warm climates. Young are born fully furred with eyes open; they are well camouflaged and are mobile within minutes of birth, thus females do not protect or even stay with the young except during nursing. The average litter size is around four, but may be as low as two and as high as seven in warm regions.

 

The black-tailed jackrabbit does not migrate or hibernate during winter and uses the same habitat of 0.4 to 1.2 mi2 (1–3 km2) year-round. Its diet is composed of various shrubs, small trees, grasses, and forbs. Shrubs generally comprise the bulk of fall and winter diets, while grasses and forbs are used in spring and early summer, but the pattern and plant species vary with climate. The black-tailed jackrabbit is an important prey species for raptors and carnivorous mammals, such as eagles, hawks, owls, coyotes, foxes, and wild cats. The hares host many ectoparasites including fleas, ticks, lice, and mites; for this reason, hunters often avoid collecting them.

 

Description:

Like other jackrabbits, the black-tailed jackrabbit has distinctive long ears, and the long powerful rear legs characteristic of hares. Reaching a length about 2 ft (61 cm), and a weight from 3 to 6 lb (1.4 to 2.7 kg), the black-tailed jackrabbit is the third-largest North American jackrabbit, after the antelope jackrabbit and the white-tailed jackrabbit. Additionally, the much more northerly Arctic hare and Alaskan hare are somewhat larger than the jackrabbit members of the hare genus. The black-tailed jackrabbit's dorsal fur is agouti (dark buff peppered with black), and its undersides and the insides of its legs are creamy white. The ears are black-tipped on the outer surfaces, and unpigmented inside. The ventral surface of the tail is grey to white, and the black dorsal surface of the tail continues up the spine for a few inches to form a short, black stripe. The females are larger than males, with no other significant differences.

 

Lifestyle:

Male black-tailed jackrabbits reach sexual maturity around 7 months of age. Females usually breed in the spring of their second year, although females born in spring or early summer may breed in their first year. Ovulation is induced by copulation. The breeding season is variable depending upon latitude and environmental factors. In the northern part of their range in Idaho, black-tailed jackrabbits breed from February through May. In Utah, they breed from January through July, with over 75% of females pregnant by April. The Kansas breeding season extends from January to August. Breeding in warm climates continues nearly year-round. Two peak breeding seasons corresponding to rainfall patterns and growth of young vegetation occur in California, Arizona, and New Mexico. In Arizona, for example, breeding peaks during winter (January–March) rains and again during June monsoons.

 

The gestation period ranges from 41 to 47 days. More litters are born in warm climates: the number of litters born each year ranges from two per year in Idaho to seven in Arizona. Litter sizes are largest in the northern portions of black-tailed jackrabbit's range and decrease toward the south. Average litter size has been reported at 4.9 in Idaho, 3.8 in Utah, and 2.2 in Arizona.

 

Female black-tailed jackrabbits do not prepare an elaborate nest. They give birth in shallow excavations called forms that are no more than a few centimeters deep. Females may line forms with hair prior to giving birth, but some drop litters in existing depressions on the ground with no further preparation. Young are born fully furred with eyes open, and are mobile within minutes of birth. Females do not protect or even stay with the young except during nursing. Ages of weaning and dispersal are unclear since the young are well camouflaged and rarely observed in the field. Captive black-tailed jackrabbits are fully weaned by 8 weeks. The young stay together for at least a week after leaving the form.

Most lionesses reproduce by the time they are four years of age. Lions do not mate at a specific time of year and the females are polyestrous. Like those of other cats, the male lion's penis has spines that point backward. During withdrawal of the penis, the spines rake the walls of the female's vagina, which may cause ovulation. A lioness may mate with more than one male when she is in heat. Generation length of the lion is about seven years. The average gestation period is around 110 days; the female gives birth to a litter of between one and four cubs in a secluded den, which may be a thicket, a reed-bed, a cave, or some other sheltered area, usually away from the pride. She will often hunt alone while the cubs are still helpless, staying relatively close to the den. Lion cubs are born blind; their eyes open around seven days after birth. They weigh 1.2–2.1 kg (2.6–4.6 lb) at birth and are almost helpless, beginning to crawl a day or two after birth and walking around three weeks of age. To avoid a buildup of scent attracting the attention of predators, the lioness moves her cubs to a new den site several times a month, carrying them one-by-one by the nape of the neck.

 

Usually, the mother does not integrate herself and her cubs back into the pride until the cubs are six to eight weeks old. Sometimes the introduction to pride life occurs earlier, particularly if other lionesses have given birth at about the same time. When first introduced to the rest of the pride, lion cubs lack confidence when confronted with adults other than their mother. They soon begin to immerse themselves in the pride life, however, playing among themselves or attempting to initiate play with the adults. Lionesses with cubs of their own are more likely to be tolerant of another lioness's cubs than lionesses without cubs. Male tolerance of the cubs varies—one male could patiently let the cubs play with his tail or his mane, while another may snarl and bat the cubs away.

Pride lionesses often synchronise their reproductive cycles and communal rearing and suckling of the young, which suckle indiscriminately from any or all of the nursing females in the pride. The synchronisation of births is advantageous because the cubs grow to being roughly the same size and have an equal chance of survival, and sucklings are not dominated by older cubs.Weaning occurs after six or seven months. Male lions reach maturity at about three years of age and at four to five years are capable of challenging and displacing adult males associated with another pride. They begin to age and weaken at between 10 and 15 years of age at the latest.

 

When one or more new males oust the previous males associated with a pride, the victors often kill any existing young cubs, perhaps because females do not become fertile and receptive until their cubs mature or die. Females often fiercely defend their cubs from a usurping male but are rarely successful unless a group of three or four mothers within a pride join forces against the male. Cubs also die from starvation and abandonment, and predation by leopards, hyenas and wild dogs.Up to 80% of lion cubs will die before the age of two. Both male and female lions may be ousted from prides to become nomads, although most females usually remain with their birth pride. When a pride becomes too large, however, the youngest generation of female cubs may be forced to leave to find their own territory. When a new male lion takes over a pride, adolescents both male and female may be evicted. Lions of both sexes may be involved in group homosexual and courtship activities; males will also head-rub and roll around with each other before simulating sex together.

As I mentioned in the first photo I posted from our trip to Africa in June/July of this year, we only saw two leopards the entire trip. Disappointing and unusual...but we saw many more cheetahs than we normally see. I have to say I love that even though it would have been nice to have my son and his family see more leopards, cheetahs are probably what I consider the most attractive predators in Africa. Beautifully marked, slender, powerful...and very calm predators.

From Wikipedia: The cheetah (Acinonyx jubatus) is a large cat of the subfamily Felinae that occurs in Southern, North and East Africa and and a few localities in Iran. The species is IUCN Red Listed as vulnerable, as it suffered a substantial decline in its historic range in the 20th century due to habitat loss, poaching, illegal pet trade, and conflict with humans. By 2016, the global cheetah population has been estimated at approximately 7,100 individuals in the wild. Several African countries have taken steps to improve cheetah conservation measures.

 

It is the fastest land animal. The only extant member of the genus Acinonyx, the cheetah was formally described by Johann Christian Daniel von Schreber in 1775. The cheetah is characterised by a slender body, deep chest, spotted coat, small rounded head, black tear-like streaks on the face, long thin legs and long spotted tail. Its lightly built, slender form is in sharp contrast with the robust build of the big cats, making it more similar to the cougar. The cheetah reaches nearly 70 to 90 cm (28 to 35 in) at the shoulder, and weighs 21–72 kg (46–159 lb). Though taller than the leopard, it is notably smaller than the lion. Typically yellowish tan or rufous to greyish white, the coat is uniformly covered with nearly 2,000 solid black spots.

 

Cheetahs are active mainly during the day, with hunting their major activity. Adult males are sociable despite their territoriality, forming groups called coalitions. Females are not territorial; they may be solitary or live with their offspring in home ranges. Carnivores, cheetah mainly prey upon antelopes and gazelles. They will stalk their prey to within 100–300 m (330–980 ft), charge towards it and kill it by tripping it during the chase and biting its throat to suffocate it to death. Cheetahs can reach speeds of 112 km/h (70 mph) in short bursts, but this is disputed by more recent measurements. The average speed of cheetahs is about 64 km/h (40 mph). Cheetahs are induced ovulators, breeding throughout the year. Gestation is nearly three months long, resulting in a litter of typically three to five cubs (the number can vary from one to eight). Weaning occurs at six months; siblings tend to stay together for some time. Cheetah cubs face higher mortality than most other mammals, especially in the Serengeti region. Cheetahs inhabit a variety of habitats – dry forests, scrub forests and savannahs.

 

Because of its prowess at hunting, the cheetah was tamed and used to kill game at hunts in the past. The animal has been widely depicted in art, literature, advertising and animation.

 

The cheetah's closest relatives are the cougar (Puma concolor) and the jaguarundi (Herpailurus yagouaroundi).[These three species together form the Puma lineage, one of the eight lineages of Felidae. The sister group of the Puma lineage is a clade of smaller Old World cats that includes the genera Felis, Otocolobus and Prionailurus.

 

Although the cheetah is an African cat, molecular evidence indicates that the three species of the Puma lineage evolved in North America two to three million years ago, where they possibly had a common ancestor during the Miocene. They possibly diverged from this ancestor 8.25 million years ago. The cheetah diverged from the puma and the jaguarundi around 6.7 million years ago. A genome study suggests that cheetahs experienced two genetic bottlenecks in their history, the first about 100,000 years ago and the second about 12,000 years ago, greatly lowering their genetic variability. These bottlenecks may have been associated with migrations across Asia and into Africa (with the current African population founded about 12,000 years ago), and/or with a depletion of prey species at the end of the Pleistocene.

Today is Monday. It's a day when I begin one of my programs at work by displaying one of my Flickr photos on a large screen, in order to talk to residents in a retirement community about a zoo animal.

 

I'm thinking about how animals use scent. Should I talk about estrous, the time just before ovulation, in which some mammals are more receptive to mating? Or, should I show photos I posted a few days ago, of mustelids (a mink and an otter) marking objects to communicate with scent?

 

I'll decide when I get there. Here is Code, the common eland, checking the scent offered by the mother of his children.

Nyala

 

Kruger National Park is one of the largest game reserves in Africa. It covers an area of 19,485 km2 (7,523 sq mi) in the provinces of Limpopo and Mpumalanga in northeastern South Africa, and extends 360 km (220 mi) from north to south and 65 km (40 mi) from east to west. The administrative headquarters are in Skukuza. Areas of the park were first protected by the government of the South African Republic in 1898, and it became South Africa's first national park in 1926.

 

To the west and south of the Kruger National Park are the two South African provinces of Limpopo and Mpumalanga. In the north is Zimbabwe, and to the east is Mozambique. It is now part of the Great Limpopo Transfrontier Park, a peace park that links Kruger National Park with the Gonarezhou National Park in Zimbabwe, and with the Limpopo National Park in Mozambique.

 

The park is part of the Kruger to Canyons Biosphere an area designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) as an International Man and Biosphere Reserve (the "Biosphere").

 

The park has nine main gates allowing entrance to the different camps.

The lowland nyala or simply nyala (Tragelaphus angasii), is a spiral-horned antelope native to southern Africa. It is a species of the family Bovidae and genus Tragelaphus, previously placed in genus Nyala. It was first described in 1849 by George French Angas. The body length is 135–195 cm (53–77 in), and it weighs 55–140 kg (121–309 lb). The coat is maroon or rufous brown in females and juveniles, but grows a dark brown or slate grey, often tinged with blue, in adult males. Females and young males have ten or more white stripes on their sides. Only males have horns, 60–83 cm (24–33 in) long and yellow-tipped. It exhibits the highest sexual dimorphism among the spiral-horned antelopes. It is not to be confused with the endangered mountain nyala living in the Bale region of Ethiopia).

 

The nyala is mainly active in the early morning and the late afternoon. It generally browses during the day if temperatures are 20–30 °C (68–86 °F) and during the night in the rainy season. As a herbivore, the nyala feeds upon foliage, fruits and grasses, and requires sufficient fresh water. A shy animal, it prefers water holes rather than open spaces. The nyala does not show signs of territoriality, and individuals' areas can overlap. They are very cautious creatures. They live in single-sex or mixed family groups of up to 10 individuals, but old males live alone. They inhabit thickets within dense and dry savanna woodlands. The main predators of the nyala are lion, leopard and African wild dog, while baboons and raptorial birds prey on juveniles. Mating peaks during spring and autumn. Males and females are sexually mature at 18 and 11–12 months of age respectively, though they are socially immature until five years old. After a gestational period of seven months, a single calf is born.

 

The nyala's range includes Malawi, Mozambique, South Africa, Eswatini, Zambia, and Zimbabwe. It has been introduced to Botswana and Namibia, and reintroduced to Eswatini, where it had been extinct since the 1950s. Its population is stable, and it has been listed as of least concern by the International Union for Conservation of Nature. The principal threats to the species are poaching and habitat loss resulting from human settlement. The males are highly prized as game animals in Africa.

 

Taxonomy and naming

 

The nyala was first described by George French Angas, an English naturalist, in 1849. The scientific name of nyala is Tragelaphus angasii. The name angasii is attributed to Angas, who said that John Edward Gray had named this species after Angas' father, George Fife Angas of South Australia. According to Article 50.1.1 of the International Code of Zoological Nomenclature and International Commission on Zoological Nomenclature, though, this is insufficient to state Gray as the author. The name "nyala" is the Tsonga name for this antelope, which is likely the source of the English, along with Zulu inyala. Its first known use was in 1899. The word has a Bantu origin, similar to the Venda word dzì-nyálà (nyala buck).

 

The nyala is the second taxon to branch off from the tragelaphine family tree just after the lesser kudu. As the nyala line has remained separate for a considerable time (over 5 million years), some authorities have placed it in its own monotypic genus Nyala. Nyala was proposed in 1912 by American zoologist Edmund Heller, who also proposed Ammelaphus for the lesser kudu, but it was not widely recognized. It was re-erected as a valid genus in 2011 under the classification of Peter Grubb and Colin Groves, but has not been embraced by taxonomic authorities such as the Mammal Diversity Database.

  

In 2005, Sandi Willows-Munro (of the University of KwaZulu-Natal) and colleagues carried out a mitochondrial DNA analysis of the nine Tragelaphus species. Mitochondrial DNA and nuclear DNA data were compared. The results showed the tribe Tragelaphini to be monophyletic, with the lesser kudu (T. imberbis) basal in the phylogeny, followed by the nyala. On the basis of mitochondrial data, studies have estimated that the lesser kudu separated from its sister clade around 13.7 million years ago. However, nuclear DNA data shows lesser kudu and nyala forming a clade, which collectively separated from the sister clade 13.8 million years ago.

 

Genetics and evolution

 

The nyala has 55 male chromosomes and 56 female chromosomes. The Y chromosome has been translocated onto the 14th chromosome, as in other tragelaphids, but no inversion of the Y chromosome occurs. Cranial studies have shown that the mountain nyala and nyala, though sharing a common name, are actually distant relatives.

 

Fossil evidence suggests that the nyala has been a separate species since the end of the Miocene (5.8 million years ago). Genetic evidence suggests that the proto-nyala had some early hybridization with the proto-lesser kudu, but the two have remained separate long after this crossing.

 

Physical description

 

The nyala is a spiral-horned and middle-sized antelope, between a bushbuck and a kudu. It is considered the most sexually dimorphic antelope.[The nyala is typically between 135–195 cm (53–77 in) in head-and-body length. The male stands up to 110 cm (43 in), the female is up to 90 cm (3.0 ft) tall. Males weigh 98–125 kg (216–276 lb), while females weigh 55–68 kg (121–150 lb). Life expectancy of the nyala is about 19 years.

 

The coat is rusty or rufous brown in females and juveniles. It grows a dark brown or slate grey in adult males, often with a bluish tinge. Females and young males have ten or more white vertical stripes on their sides. Other markings are visible on the face, throat, flanks and thighs. Stripes are very reduced or absent in older males. Both males and females have a white chevron between their eyes, and a 40–55 cm (16–22 in) long bushy tail white underside. Both sexes have a dorsal crest of hair running right from the back of the head to the end of the tail. Males have another line of hair along the midline of their chest and belly.

 

Only the males have horns. Horns are 60–83 cm (24–33 in) long and yellow-tipped. There are one or two twists.The spoor is similar to that of the bushbuck, but larger. It is 5–6 cm (2.0–2.4 in) long. The feces resemble round to spherical pellets. The nyala has hairy glands on its feet, which leave their scent wherever it walks.

 

The condition of the nyala often varies between the sexes. According to a study, this can be attributed to the differences in their body sizes. It was noted that during nutritional stress, old adults died in more numbers, of which most were males. During an attempt of blood sampling in the nyala, it was found that Vitamin E levels varied during stress.

 

Parasites

 

A study of the helminths from 77 nyalas from four game reserves in Natal revealed the presence of ten nematode species and four nematode genera, a trematode species and paramphistomes (members of superfamily Paramphistomoidea), and two cestode genera. The research discovered new parasites that the nyala was host of - namely a Cooperia rotundispiculum race, Gaigeria pachyscelis, a Gongylonema species, Haemonchus vegliai, Impalaia tuberculata, an Oesophagostomum species, a Setaria species, Trichostrongylus deflexus, Trichostrongylus falculatus, the larval stage of a Taenia species, a Thysaniezia species and Schistosoma mattheei. Ostertagia harrisi and C. rotundispiculum were the most dominant nematodes in the antelope.

 

Another study of 97 blood samples of South African nyalas revealed the presence of tick-borne hemoparasites (blood parasites). The methods used were polymerase chain reaction (PCR) and reverse line blot (RLB) hybridization. The dominant parasites were Theileria species, T. buffeli, T. bicornis, Ehrlichia species, Anaplasma marginale and A. bovis. Ten tick species, two louse species and a louse fly species were recovered in a study of 73 nyalas at Umfolozi, Mkuzi and Ndumu Game Reserves in northeastern KwaZulu-Natal in 1983 and 1984 and an additional six individuals in 1994. It was found that nyalas were hosts to all stages of development in Boophilus decoloratus, Rhipicephalus appendiculatus and R. muehlensi and the immature stages of Amblyomma hebraeum and Rhipicephalus maculatus. Adult males served hosts to more number of ticks and lice than adult females did. Also, a trypanosome was isolated from a nyala, wild-caught in Mozambique, which was diagnosed and found as akin to Trypanosoma vivax, based on biological, morphological and molecular data.

 

Diseases

 

The nyala can also suffer from myopathy. In between January 1973 and June 1981, 21 nyalas succumbed to the disease. The main symptoms were stiffness, inability to rise, and failure to suckle in newborns. Necrosis (that is, the premature death of cells in a living tissue) and mineralization were found in the skeletal muscle after a histological analysis. In the juveniles there was acute necrosis of the cardiac muscle. In adults, there was interstitial fibrosis of the cardiac muscle, along with arteriosclerosis.

 

In a report published in 1994 entitled "Epidemiological observations on spongiform encephalopathies in captive wild animals in the British Isles", it was noted that spongiform encephalopathy had been diagnosed in one nyala captive in a zoo. The nyala was formerly affected by the disease rinderpest, although the viral disease is considered eradicated now.

 

Ecology and behavior

 

he nyala is active mainly in the early morning and late afternoon. It browses during the day if temperatures are 20–30 °C (68–86 °F) and during the night in rainy season. These antelopes rest in thick bushes during the hot hours of the day. The nyala is very shy and cautious in nature, and often remains hidden rather than coming out in the open. Most sightings of the nyala in the wild are at water holes. But in protected areas they become less shy and often come out in view of tourists.

 

Nyala groups are according to sex or mixed. Herds usually browse and drink water together. Each group consists of two to ten individuals. A study in Zinave National Park at Mozambique showed that 67% of the observations were of groups of one to three nyalas, and the rest of the herds consisted of up to 30 nyalas. Herds often broke up and re-formed. Generally adult males remain alone. Females often remain near their mothers when they have their offspring, so the relationships in female herds may be closer than those of males.

 

Alert and wary in nature, the nyala use a sharp, high, dog-like bark to warn others in a group of danger. This feature is mainly used by females. They also react to the alarm calls of impala, baboon and kudu. The impala has been found to react to the calls of the nyala as well. The main predators of nyala are lion, leopard, cheetah, spotted hyena, African wild dog and nile crocodile while baboons and raptorial birds are predators of juveniles.

 

Diet

 

As a herbivore, the nyala's diet consists of foliage, fruits, flowers and twigs. During the rainy season they feed upon the fresh grass. They need a regular intake of water, and thus choose places with a water source nearby. However, they are adapted to live in areas with only a seasonal availability of water. A study in Zululand showed that the nyala fed mainly in the early morning and the late afternoon. They feed at night during the rainy season.

 

A study in Mkhuze Game Reserve and Ndumu Game Reserve in Natal focused on the dietary habits of the impala and the nyala showed that the amount of dicotyledons in their diets varied seasonally. In the dry season, the nyala's dicotyledon diet content was 83.2% and the impala's 52%. In this season, the diet grew richer in fiber and dietary proteins were less. The reverse occurred in the rainy season. As the rainy season arrived, both species took to a diet of mainly monocotyledons, and the impala consumed more of them. The diet contained more proteins than fiber.

 

Another study was done to find whether the sexual dimorphism in the nyala influenced its foraging habits. Vegetation surveys were conducted with the end of each feeding bout. It was found that females spent equal periods of time foraging in all the three habitats, but males preferred sand forest more. More differences were noted, as males ate woody species at a greater average height whereas females fed from the low herbaceous layer. It was concluded that the differences resulted from varying nutritional and energetic demands according to their diverse body sizes and differing reproductive strategies.

 

Reproduction

 

The nyala breeds throughout the year, but mating peaks in spring and autumn. The reason for this is still unknown, but attributed to the photoperiod and the feeding habits of the animal. Females reach sexual maturity at 11 to 12 months of age and males at 18 months (though they are socially immature until five years old), though they begin to show active spermatogenesis at 14 months.

 

Before ovulation, the Graafian follicles reach a length of at least 6.7 cm (2.6 in). A female's estrous cycle is about 19 days long. Males will attempt to mate with the female for two days of the cycle, but she allows it for only six hours per cycle. When the male enters a females' herd during mating, he makes a display by raising his white dorsal crest, lowering his horns and moving stiffly. As in many other animals, the males fight over dominance during mating.

 

The kidney fat indices (KFIs) of impalas and nyalas have been studied to understand the influence of social class and reproduction on them. To determine the KFI, the kidney is removed and weighed with the fat and once again excluding the fat. The resultant difference is the amount of fat on the kidney. The more the fat, the healthier the animal. In rut, male nyalas had lower KFIs, which did not vary much with the season. Pregnant females of both nyala and impala had higher KFIs than non-pregnant ones.

 

There is a significant increase in corpus luteum in the last third of gestation. Gestation is of seven months. A single calf is born, weighing 5 kg (11 lb). Birth takes place generally away from the sight of predators, in places such as a thicket. The calf remains hidden for up to 18 days, and the mother nurses it at regular intervals. The calf remains with its mother until the birth of the next calf, during which males in rut drive it away from the mother.

 

Habitat and distribution

 

The nyala inhabits dense lowland woodlands and thickets, mainly in southern Malawi, Mozambique, Zimbabwe, and eastern South Africa. It chooses places with good quality grasslands as well as provision of fresh water. It also inhabits lush green river country. The nyala's natural range stretches across southeast Africa from the Lower Shire Valley in Malawi through Mozambique and Zimbabwe to eastern South Africa and Eswatini.

 

The geographic distribution of the nyala may be based on the genetic variation. According to a study of nyala in South Africa, Mozambique, Malawi and Zimbabwe, there was a marked difference in the gene frequencies at three microsatellite loci. Mitochondrial DNA analysis revealed the presence of a unique haplotype in individuals from each location. Thus, the geographic variation in the nyala may be due to a distribution pattern based on habitat specificity.

 

Today nyala are found in South African protected areas in the Ndumo Game Reserve, uMkuze Game Reserve and Hluhluwe-Umfolozi Game Reserve, all in KwaZulu-Natal, as well as in Kruger National Park. As of 1999, 10–15% of nyala occurred on private land. Efforts are being made to retain the populations of nyala in Gorongosa National Park and Banhine National Park in Mozambique. Nyala also thrive in Lengwe National Park in Malawi.

 

Nyala have never been observed showing territoriality. Territories of either sex overlap extensively. The home ranges of males are approximately equal to that of females, about 10 square kilometres (3.9 sq mi) in area.

 

Threats and conservation

 

The major threats to the population of the nyala are poaching, habitat loss, agriculture and cattle grazing. Rinderpest outbreaks have also contributed in population loss. This species is currently of Least Concern, and the population is considered stable by both the IUCN and CITES. As of 1999, the total population of the nyala was around 32,000 individuals. More recent estimates show that South Africa has at least 30,000 nyalas, with 25,000 in KwaZulu-Natal. There are now more than 1,000 on protected areas and ranches in Eswatini. In Mozambique there are not more than 3,000, in Zimbabwe over 1,000, and numbers in Malawi have fallen from 3,000 to about 1,500. Namibia has the smallest population, at about 250.

 

Today over 80% of the total population is protected in national parks and sanctuaries, mostly in South African protected areas. In South Africa there is a high demand for adult males as game trophies.

Der Kruger-Nationalpark (deutsch häufig falsch Krüger-Nationalpark) ist das größte Wildschutzgebiet Südafrikas. Er liegt im Nordosten des Landes in der Landschaft des Lowveld auf dem Gebiet der Provinz Limpopo sowie des östlichen Abschnitts von Mpumalanga. Seine Fläche erstreckt sich vom Crocodile-River im Süden bis zum Limpopo, dem Grenzfluss zu Simbabwe, im Norden. Die Nord-Süd-Ausdehnung beträgt etwa 350 km, in Ost-West-Richtung ist der Park durchschnittlich 54 km breit und umfasst eine Fläche von rund 20.000 Quadratkilometern. Damit gehört er zu den größten Nationalparks in Afrika.

 

Das Schutzgebiet wurde am 26. März 1898 unter dem Präsidenten Paul Kruger als Sabie Game Reserve zum Schutz der Wildnis gegründet. 1926 erhielt das Gebiet den Status Nationalpark und wurde in seinen heutigen Namen umbenannt. Im Park leben 147 Säugetierarten inklusive der „Big Five“, außerdem etwa 507 Vogelarten und 114 Reptilienarten, 49 Fischarten und 34 Amphibienarten.

Der Nyala (Nyala angasii, Syn.: Tragelaphus angasii) ist eine südostafrikanische Antilope aus der Gruppe der Waldböcke. Zur Unterscheidung vom Bergnyala wird er manchmal auch als Flachland-Nyala oder Tiefland-Nyala bezeichnet. Die Bezeichnung Nyala stammt aus dem Swahili.

 

Der Nyala galt lange als eine der seltensten Antilopenarten. Strenge Schutzmaßnahmen haben dazu beigetragen, dass sich die Bestände wieder erholt haben. Trotzdem zählt der Nyala zu den immer noch sehr wenig erforschten Hornträgern.

 

Aussehen

 

Diese Antilopenart erreicht eine Kopfrumpflänge von 140 cm und eine Schulterhöhe von 110 cm. Das Gewicht beträgt 55 bis 125 kg, wobei Männchen deutlich größer und schwerer als Weibchen sind.

 

Weibchen und Männchen lassen sich vor allem anhand ihrer Körperfärbung unterscheiden: Während die viel größeren männlichen Tiere schiefergrau gefärbt sind und schraubenartig gedrehte Hörner tragen, die mit einer weißen Spitze versehen sind, sind die weiblichen Tiere ebenso wie Jungtiere hornlos und überwiegend rötlichbraun gefärbt. Alle Tiere haben bis zu 18 schmale, weiße Querstreifen. Die Männchen tragen sowohl eine lange, erektile Mähne, die das Rückgrat bedeckt, als auch von der Kehle bis zu den Hinterläufen hängende Bauchmähne. Dieses Merkmal unterscheidet sie von den meisten anderen Antilopenarten. Der buschige Schwanz ist bei beiden Geschlechtern an der Unterseite weiß.

 

Verbreitung

 

Nyalas sind in Mosambik, Simbabwe und im äußersten Nordosten Südafrikas verbreitet. Eingeführt wurden sie außerdem in Nationalparks Botswanas und Südafrikas, in denen sie ursprünglich nicht heimisch gewesen waren. Sie leben bevorzugt in dichtem Buschwerk in der Nähe von Wasser. Das Vorkommen ist in den Naturschutzgebieten Hluhluwe/Umfolozi, Mkuzi, Ndumo und Krügerpark bekannt. In den letzten Jahren wurde ebenfalls eine Population im Isimangaliso Park wieder angesiedelt.

 

Lebensweise

 

Während Weibchen und Jungtiere kleine Herden bilden, sind die männlichen Tiere Einzelgänger. Die Nyalas ernähren sich vorwiegend von Laub, doch werden gelegentlich auch Gräser gefressen. Zu den Fressfeinden des Nyalas zählt unter anderem der Leopard, dieser hat jedoch keine signifikante Auswirkung auf den Bestand dieser Art.

 

Fortpflanzung

 

Nach einer Tragzeit von gut sieben Monaten bringt das Weibchen ein Junges zur Welt. Das Höchstalter der Tiefland-Nyalas liegt bei etwa 16 Jahren.
