While walking in the Farnham Estate in Cavan I came across this ecosystem in a tree! It reminded me of the giant Kauri tree known as Tane Mahuta in the forest of Waipoua in New Zealand! This may not be quite as big but the range of plants living on it are almost as spectacular!

To consider termites plunderers is unfair. They are the most important animals in a forest ecosystem, single-handedly decomposing 40% to 100% of the decaying wood and thereby enriching the soil. Subterranean termites, which are among the ones that bothers us humans, serve us well too. As they tunnel through the soil, building swarming tubes to forage for food, they increase the soil’s porosity, facilitating greater percolation of water. Termites are known to dig as deep as over 100 feet in search of water to maintain the humidity of their mounds. As early as 500 CE, Indian astronomer Varahamihira wrote in the Brihat-Samhita that termite mounds were indicators of ground water and mineral deposits.
Un écosystème a été recréé dans la Serre afin de pouvoir permettre aux lépidoptères d’y vivre dans des conditions optimales :
Température moyenne de 28° C.
Hygrométrie de 80 % à 83 %, avec un maximum de 85 %
Utilisation de la lutte biologique intégrée (LBI) permettant la non-utilisation de pesticide ni d’aucun agent chimique :
des insectes pour la plupart invisibles à l’œil nu, ainsi que des cailles de Chine sont lâchés dans la serre afin qu’ils s’attaquent aux microbes et pucerons prédateurs des papillons
The Rock Islands of Palau are a collection of several hundred limestone and coral uprises in the Palauan archipelago. They are extremely important to Palau as they support biodiversity, fisheries, tourism, and cultural values. The islands are also famous for their beaches, blue/turquoise lagoons, and have made UNESCO heritage status. There are over 746 species of fish, over 385 corals, 13 species of shark and manta rays, 7 species of giant clams, and all the endemic birds and over half of the endemic plants of Palau.

A small nontoxic ecosystem in a bottle. Why should it be so hard to think of our planet just like this? I don't think anyone would think of putting poison in this for a optimum life.

Prides are family units that may comprise anywhere from two to 40 lions—including up to to three or four males, a dozen or so females, and their young. All of a pride's lionesses are related, and female cubs typically stay with the group as they age.
Happy Birthday Peggy! Dedicated to my beautiful, big sister, Peggy, who is celebrating her birthday today in Vancouver. I can hardly wait for her to join me in Toronto to go on photo walks together and to play endless games of Scrabble. Peggy you are wished love, health, happiness and abundance. I'm so proud to be your sister. flic.kr/ps/aTpZh
Panoramic view of the Mimico Waterfront Park, along which I took my grandson Quincy for a walk in his stroller this morning.
"This park lies on the Lake Ontario Waterfront between Humber Bay Park West and Norris Crescent Parkette. Its features include 1.1km of multi-use waterfront trail, headlands and cobble beaches, a small bay, boardwalks with small pockets of wetland habitat between the boardwalk and shoreline, and terrestrial and aquatic habitat enhancements to support healthy ecosystems."
It really feels likes Spring in Toronto and i couldn't be happier! Thanks for visiting, enjoy your week.
It has just come to my attention that today is National Bird Day. I didn't want to miss this occasion so I am honoring this day with a photo of my very favorite songbird, the American Dipper. While parked at a pullout in Lamar River Valley we heard birdsong coming from a nearby bridge. Following the song we wandered down to find this Dipper. Prior to this I had not even known of its existence but this bird quickly stole my heart. The Dipper is an aquatic songbird that can dive several feet below the water's surface in search of food. As soon as it resurfaces it continues singing its beautiful tune.
The purpose of National Bird Day is to raise awareness that nearly "12 percent of the world's 9,800 bird species may face extinction within the next century,...Birds are a sentinel species whose plight serves as a barometer of ecosystem health and alert system for detecting global environment ills."
Because of its need for clean water streams or rivers the Dipper is an indicator species of water quality. If you see a dipper in a stream or river, you know the water is free from pollutants. October 30, 2014

The San Pedro riparian area, containing about 40 miles of the upper San Pedro River, was designated by Congress as a National Conservation Area on November 18, 1988. The primary purpose for the designation is to protect and enhance the desert riparian ecosystem, a rare remnant of what was once an extensive network of similar riparian systems throughout the Southwest.
Many recreational opportunities are available within the NCA. Murray Springs Clovis Site, a significant archaeological site contains an undisturbed stratigraphic record of the past 40,000 years. Excavations were conducted by the University of Arizona from 1966 to 1971. People first arrived in this area 11,000 years ago. They belonged to what we now call the Clovis Culture and were the earliest known people to have inhabited North America. Named after the distinctive and beautifully crafted Clovis spear points they made, they were expert hunters of the large mammals of the last Ice Age. An interpretive trail leads visitors through the site. From Sierra Vista, take State Highway 90 east 6 miles to Monson Road. Turn left, and go about 1.2 miles to the signed turnoff to Murray Springs. The access road is located on the right.
The Spanish Presidio Santa Cruz de Terrenate is the most intact remaining example of a once-extensive network of similar presidios. These fortresses marked the northern extension of New Spain into the New World. Only a stone foundation and a few remaining adobe wall remnants mark the location of an isolated and dangerous military station. From Fairbank on Highway 82, drive approximately 2 miles west on Highway 82, turn right on the Kellar Ranch Road and travel approximately 3 miles to the trailhead. Hike about 2 miles to the ruins and interpretive displays.
The San Pedro House, located 9 miles east of Sierra Vista on State Highway 90, is a popular trailhead for birdwatchers, hikers, and mountain bikers. The Friends of San Pedro operate a bookstore and information center.

This fern was growing in the moss on the giant beech I posted last week. It's amazing how these big trees can be a harbour for so many plants, animals and insects!

The Red Sea is a rich and diverse ecosystem. More than 1200 species of fish have been recorded in the Red Sea, and around 10% of these are found nowhere else. This also includes 42 species of deepwater fish.The rich diversity is in part due to the 2,000 km (1,240 mi) of coral reef extending along its coastline; these fringing reefs are 5000–7000 years old and are largely formed of stony acropora and porites corals. The reefs form platforms and sometimes lagoons along the coast and occasional other features such as cylinders (such as the Blue Hole (Red Sea) at Dahab). These coastal reefs are also visited by pelagic species of red sea fish, including some of the 44 species of shark.
The Red Sea also contains many offshore reefs including several true atolls. Many of the unusual offshore reef formations defy classic (i.e., Darwinian) coral reef classification schemes, and are generally attributed to the high levels of tectonic activity that characterize the area.The special biodiversity of the area is recognized by the Egyptian government, who set up the Ras Mohammed National Park in 1983. The rules and regulations governing this area protect local marine life, which has become a major draw for diving enthusiasts.
Al-Qusair (Arabic, القصير, sometimes romanized as Al Qusayr, El Quseir, Quseir, Quesir, Qusseir, Qosseir, or Kosseir), is an approximately 5000 year old Egyptian city lying along the Red Sea. Its ancient name was Leucus Limen.
Al-Qusair is located 205 kilometers south of Hurghada, 103km north of Marsa Alam and 73km north of the Marsa Alam International Airport. Its population was approximately 20,000 as of 1986. Today, its population is around 50,000.
Il Mar Rosso offre una spettacolare barriera corallina, con una biodiversità eccezionale,ha una superficie di 43.000 km2 e prende il nome da un tipo di alga colore rosso che raramente appare in larga quantità sulla superficie delle sue acque. Da un punto di vista fisico viene considerato un golfo dell'Oceano Indiano.Il Mar Rosso è situato tra l'Africa e il Medio Oriente e presenta un'alta concentrazione di sale, pari a circa il 42%. La fauna che popola i fondali marini è straordinariamente diversificata. C'è addirittura chi sostiene che, per quanto riguarda i coralli, i pesci e altri organismi marini, il Mar Rosso sia il più ricco di tutto l'Oceano Indiano. Il suo isolamento geografico ha dato vita nei secoli a delle specie marine uniche, che è possibile osservare solo lungo la sua barriera corallina.
Le sue acque sono di un colore azzurro chiaro e cristallino, che permettono di osservare determinate specie di pesce anche a occhio nudo.
El Quseir da qualche anno è diventata una nuova meta turistica per gli appassionati di barriera corallina. Si trova nel Mar Rosso lungo la costa meridionale dell’Egitto, verso il confine con il Sudan, a metà strada tra Hurghada e Marsa Alam.
La zona non è ancora stata presa d’assalto dal turismo di massa e quindi riserva a sub e appassionati di snorkeling panorami subacquei entusiasmanti. Davanti a centinaia di chilometri di costa disabitata e senza traccia di inquinamento, si apre una barriera immersa in acque calde e trasparenti nella quale prosperano “lussuosi” giardini di coralli popolati da migliaia di specie di pesci e invertebrati. La visibilità è molto buona con medie che superano i 20 metri. L’acqua è molto calda ed anche d’inverno non scende sotto i 20°. A parte i mesi estivi centrali, il vento persistente rende il mare sempre un po’ mosso. Superata una laguna corallina dove l’acqua è calma e bassa poche decine di centimetri, si incontra la sommità della barriera dove i coralli quasi affiorano. Oltre c’è una parete a strapiombo che con un “salto” nel blu, profondo tra i 30 e i 40 metri, conduce in mare aperto.

Another digital preview from Monday's shoot with Lieke. (Flickr really did an oversharpening number on this one. Gah.)
Am trying to slowly get out of my comfort zone. Different editing, different compositions, direct sunlight, etc. I love this photo, but it also makes me uncomfortable in ways, haha. Because it's not my usual thing. But it could be a new thing ;) Who says I need only one style!
Getting my film developed today..
& a new computer is coming my way this week, I have had issues with my current computer for about a month now, so I haven't been working much on selfportraits and other projects.. Can finally get back to doing more.

I appreciate your comments and faves, so much, but please DON'T POST GROUP INVITES WITH OR WITHOUT IMAGES in my comments, I will delete them. No flickriver streams, either. #notyourstream
Thank you!
You can find links to my sites, FB pages, Twitter etc on my flickr profile - please check it out! :)
What Drew me to this shot was how such a small body of water existed so close and yet so far from the endless ocean. Reminds me of evolution, where the few life forms in the pond eventually become a different species than those in the ocean. Maybe some little fish will grow legs and upload their own pictures in Flickr some day.

In 2008 the United Nations Environment Program expressed extreme concern for the implications of climate change on the Arctic regions. A warming Arctic climate is projected to change sea temperature and melt ice sheets, destroying vital ecosystems which operate in these Arctic areas. According to NASA, even small changes in ice could mean drastic changes to our water cycle and global climate.
