Institute of Arctic Biology Despite the size and severity of the massive 2007 Anaktuvuk River fire on Alaska’s North Slope, much of the arctic vegetation has recovered and the tundra is likely to return to its pre-fire condition according to University of Alaska Fairbanks scientist Syndonia “Donie” Bret-Harte and colleagues in a recent scientific paper. In April 2007, a wall of smoke was visible 23 miles south of the fire at the UAF Institute of Arctic Biology Toolik Field Station...

Black bears show surprisingly significant and previously unobserved slowing of their metabolism during and after hibernation, according to a new study by scientists at the Institute of Arctic Biology at the University of Alaska, Fairbanks. The amount of metabolic suppression surprised the researchers, since the bears exhibited only a moderate decrease in body temperature during hibernation. "In general, an animal's metabolism slows to about half for each 10 degree (Celsius) drop in body...

Much of circumpolar Arctic research focuses on the physical, direct changes resulting from climate warming such as sea ice retreat and temperature increases. "What's understudied is the living component of the Arctic and that includes humans," said Syndonia "Donie" Bret-Harte, associate professor of biology at the University of Alaska Fairbanks and co-author of a paper to be published September 11, 2009 in the journal Science. The paper reviews current knowledge on the ecological consequences...

Two University of the Alaska Fairbanks researchers are among key contributors to a new national report that details visible effects of climate change in the United States and how today's choices stand to affect the future.The report, "Global Climate Change Impacts in the United States," is the first to focus on observed and projected climate change and its effects specifically in the United States. UAF scientists A. David McGuire and John Walsh were part of a consortium of experts from 13...
