Evaluating nutritional condition of grizzly bears via select blood parameters

Article Abstract:

Research undertaken within an area of tundra of around 40,000 sq km in the central Arctic of the North West Territories, Canada, into the use of bioelectrical impedance analysis to accurately assess the body composition of free-ranging grizzly bears indicates that blood parameters are unreliable indicators of nutritional condition in grizzly bears. It is important to be aware that albumin and hemoglobin, along with several blood parameters, vary considerably through a number of external factors. Albumin was the only blood parameter found to correlate with the overall body fat levels in both adult male and lone female grizzly bears.

Cumulative effects of human developments on Arctic wildlife

Article Abstract:

A study is conducted to demonstrate the cumulative effects of multiple sources of human disturbance for caribou, wolves, bears and wolverines found across the Canadian central Arctic. The results reveal that regional cumulative effects analyses serve as the coarsest framework for understanding the impacts of human developments on wide-ranging animals.

Displacement of mountain caribou from winter habitat by snowmobiles

Article Abstract:

The mountain caribou found in the forests of the U.S. and Canada is marked as endangered and threatened. They need a recovery plan in both countries and this is due to the disturbances by snowmobiles that displace mountain caribou from preferred habitat areas.
