Map from the U.S. Geological Survey shows projected changes in polar bear habitat from 2001 to 2010 and 2041 to 2050. Red areas indicate loss of optimal polar bear habitat; blue areas indicate gain. Polar bear population sizes and trends are difficult to estimate accurately because they occupy remote home ranges and exist at low population ...

Michigan officials hope new hunting rules — and possibly new "wildlife-only crossing" around roads — help curb the state's large deer population.
Taylor has published over 5150 scientific papers on polar-bear-related topics, and he has worked in the field on most of the world's polar bear populations. He was a coauthor of the 2008 Committee on the Status of Endangered Wildlife in Canada (COSEWIC) Assessment and Update Status Report for polar bears. From 2004 to 2008, he was also manager ...
There is also a population of Arctic fox, which typically have their territories near seabird habitats. [86] There are no caribou living on Franz Josef Land today. However, radiocarbon dating of shed antlers found on Alexandra Land in 1990 has shown that there was a population of caribou living on the island around 4000 to 2000 years ago. [44]
