The amazing pronghorn (Antilocapra americana) is North America’s fastest land mammal.
The male pronghorn has unique prong-shaped horns as shown in the image below.
Approximately only 40% of female pronghorn have horns.
Pronghorn’s conservation status is “Threatened“.
This video presents Pronghorn Passage.
Pronghorn habitats ranged from the south-central prairies of Canada through the Plains and Great Basin’s grasslands and shrubsteppes of the United States, southwestward to the semidesert grasslands and deserts of northwestern Mexico.
Recently, biologists from the U.S., Mexico, and Canada have collaborated for the first time to produce recommendations to protect and manage the pronghorn populations.
“Pronghorn Management Guides”
Biological and management principles and practices designed to sustain pronghorn populations in the USA, Mexico, and Canada.
The “Pronghorn Management Guides” fifth edition provides an updated compendium of suggested practices and techniques for managing pronghorn and pronghorn habitat.
…between 1550 and 1920,… pronghorn numbers declined due to fencing, habitat loss, competition with livestock, and year-round hunting….
More favorable weather, regulated hunting, reversion of farmland to rangeland, and translocations resulted in a great increase in pronghorn numbers to > 1 million in 1983 (Yoakum 1986). By 2000, cumulative legal harvests of > 3.5 million pronghorn were being realized (O’Gara and Morrison 2004). Population expansions are currently limited by agricultural, urban, and mining expansions onto historic rangelands; restrictions of movement by fencing; the resistance of agricultural interests to population increases; the alteration of native vegetation by certain rangeland rehabilitation programs; and range overuse. In certain locales, these and other debilitating factors are such that managers are hard pressed to even maintain existing populations….
Those that have the greatest impact on pronghorn today include roads, railroads, fences, housing, and energy production. The primary factors associated with industrial and infrastructure development which change pronghorn demographics and behavior are habitat fragmentation and loss. These account for loss of summer and winter range, and a severing of connectivity for pronghorn migration in Canada, the U.S., and Mexico. The aim of these management recommendations is to reduce these impacts on pronghorn populations…
….it is clear from past history and recent research that populations will not be maintained without deliberate conservation measures. At the core of these measures is habitat. Pronghorn are a nomadic species with movement requirements as variable as the extreme winters and lengthy droughts that typify the landscapes they utilize…
From 1988 through 1994, Byers (1997) was able to identify 84 – 136 adult pronghorn, depending on the year, on the National Bison Range by using sketches and photographs to help memorize their physical characteristics and coat patterns….
…although the pronghorn on the National Bison Range are considered wild, all of the animals are fenced in, and essentially captives….

As photographers, we all know that “it’s all about light.” The quality of the light that strikes the scene, gets reflected back into the camera’s lens and carefully focused onto the image sensor.
Well, quantum physics researchers have now developed a fundamentally new quantum imaging technique that uses the property of “entangled” pairs of photons to take pictures. They essentially shine a laser through two non-linear crystals, producing a pair of twin (“entangled”) photons in either crystal: one infrared photon and a “sister” red photon.
If a photon pair is created in the first crystal, only the infrared photon are allowed to illuminate the object. Its sister red photon never encounters the object. And yet, a picture of the object is obtained using the red photons only!
In the experiment, the laser illuminates two separate crystals, creating one pair of twin photons (consisting of one infrared photon and a “sister” red photon) in either crystal. The object is placed in between the two crystals. The arrangement is such that if a photon pair is created in the first crystal, only the infrared photon passes through the imaged object. Its path then goes through the second crystal where it fully combines with any infrared photons that would be created there.
With this crucial step, there is now, in principle, no possibility to find out which crystal actually created the photon pair. Moreover, there is now no information in the infrared photon about the object. However, due to the quantum correlations of the entangled pairs the information about the object is now contained in the red photons – although they never touched the object. Bringing together both paths of the red photons (from the first and the second crystal) creates bright and dark patterns, which form the exact image of the object.
Stunningly, all of the infrared photons (the only light that illuminated the object) are discarded; the picture is obtained by only detecting the red photons that never interacted with the object.

Canadian artist/photographer Sarah Anne Johnson will be commissioned to create the City of Toronto’s first monumental photographic mural.
Sarah Anne Johnson works in various mediums, focusing on themes of nature and idealism…For her series “Artic Wonderland” (2010-11), Johnson took photos in the Arctic Circle and altered them using paint, Photoshop, and techniques of embossing and printmaking. “I do this to create a more honest image,” she says. “To show not just what I saw, but how I feel about what I saw.”
Winnipeg-based artist Sarah Anne Johnson won the inaugural Grange Prize for contemporary photography in 2008.
Tree-planting experience in British Columbia and travels to the Galapagos Islands have led Johnson to explore the link between labour and utopia, community and landscape. Johnson holds a BFA from the University of Manitoba and an MFA from Yale.
Construction of the mural is scheduled to be completed by May 1, 2015 — in time for the opening of the Contact Photography festival and the Pan Am and Parapan Am Games.
Beginning with Lake Ontario and Toronto Island as her subject, Johnson’s site-specific new work will transform this grey city block into a magical place.

The City of Toronto’s StreetARToronto (StART) program announced today that it has been selected by Partners In Art – the volunteer-based not-for-profit group of Toronto contemporary art supporters – to receive funding support to help create the city’s first monumental photographic mural. It will be located near Toronto’s waterfront.
Working with the Scotiabank CONTACT Photography Festival, this joint partnership will provide a rare opportunity to commission a site-specific photographic artwork for the enjoyment of Toronto residents and visitors.
Thanks to a $50,000 donation by Partners In Art (PIA), the StART program, in association with Contact, will commission Canadian artist Sarah Anne Johnson to create a large-scale, site-specific photographic image for the west-facing wall of the Westin Harbour Castle Convention Centre at 11 Bay St. This site was selected due to its busy location and unique characteristics. The block-long building at the foot of Bay Street offers a unique wall surface that is suitable for a massive mural.
Triton, Neptune’s largest moon, received a visit from Voyager 2 back on August 25, 1989. Voyager 2 passed within 40,000 kilometers of Triton and took lots of images. Now, for the first time, and to commemorate the 25th anniversary of this dramatic encounter, the images have been gathered into a movie. The resolution is 600 meters per pixel and is in orange, green and blue (showing Triton in approximately natural colors).
It’s a really fast flyby and the video starts with Voyager 2 about 3 days out from Triton, travelling at a speed of approx. 25 kilometers per second, passing over the unlit north pole, pivoting to see the departing moon (now visible as a diminishing crescent) and then ending about a week on the outbound trajectory. Triton is 2706 kilometers across.
The new Triton map has a resolution of 1,970 feet (600 meters) per pixel. The colors have been enhanced to bring out contrast but are a close approximation to Triton’s natural colors. Voyager’s “eyes” saw in colors slightly different from human eyes, and this map was produced using orange, green and blue filter images.
