Few bats for Quebec’s belfries. White-nose syndrome killing North American bats.

Posted by Hannah

Photograph by: Nancy Heaslip, New York Department of Environmental Conservation MONTREAL – In March, Frédérick Lelièvre found himself crawling through a narrow passage into the final chamber of the Laflèche Cave in Val des Monts. Raising his eyes to the hibernating bats on the rock above him, his heart dropped. The tiny lime-size animals were dusted with a white powdery substance. Most of them had it on their muzzles, and it was on the wings and the feet of others. It wasn’t a good sign. Wildlife biologists in the United States have come across similar sights over the last four … Read more…

Green Living Polar bears and prophecies from the director of Earth. Earth, the hotly anticipated new film from Disneynature—in theatres on Earth Day (April 22)—follows three families of mammals. It captures the spectacle of the animal kingdom on the Arctic sea ice, in the tropics and Kalahari Desert, and at the Antarctic’s Southern Ocean. Green Living caught up with Emmy Award-winning wildlife filmmaker and Earth’s co-director Alastair Fothergill (best known for producing and directing the BBC series Planet Earth) for a chat about climate, camera angles and the thrill of the chase. Green Living: What do you hope people will … Read more…

Warmer caves may save bats from deadly fungus

Posted by admin

Shivering bats need help to fight off white-nose syndrome Researchers are hoping that heated bat boxes can curtail the number of bats dying from white-nose syndrome — a condition that has decimated hibernating bats across the northeastern United States. As many as half a million bats have died from the poorly understood ailment since it was discovered in New York state in 2006. Because the bodies of emaciated bats are often found strewn around the entrances of affected caves, scientists have hypothesized that the bats are starving to death during hibernation. Now, a pair of ecologists has created a mathematical … Read more…

Arctic Expedition: Life on the Amundsen

Posted by admin

When the CCGS Amundsen, a Canadian research ice breaker, left its home port of Quebec City in July 2007, it embarked upon a historic 15-month expedition that would have it travel across the Arctic and overwinter in the Beaufort Sea. The scientists on board the  Amundsen might spend their days hunting for ice algae, fishing for zooplankton, or surveying the contours of the nearby ice floes.   But it’s not all work and no play for the researchers and graduate students that call the Amundsen home. This slideshow was first published by The Gazette in December 2008. The World Federation of … Read more…

Permafrost that lives up to its name

Posted by admin

Ancient Canadian ice survived previous warm periods. A 740,000-year-old wedge of ice discovered in central Yukon Territory, Canada, is the oldest known ice in North America. It suggests that permafrost has survived climates warmer than today’s, according to a new study. “Previously, it was thought that the permafrost had completely disappeared from the interior about 120,000 years ago,” says Duane Froese, an earth scientist at the University of Alberta in Edmonton, Canada, who is the author of the study published today in Science. “This deep permafrost appears to have been stable for more than 700,000 years, including several periods that … Read more…
