Behavioural flexibility in an Arctic seabird using two distinct marine habitats to survive the energetic constraints of winter

Allison Patterson, H. Grant Gilchrist, Gregory J. Robertson, April Hedd, David A. Fifield & Kyle H. Elliott
Abstract Background Homeothermic marine animals in Polar Regions face an energetic bottleneck in winter. The challenges of short days and cold temperatures are exacerbated for flying seabirds with small body size and limited fat stores. We use biologging approaches to examine how habitat, weather, and moon illumination influence behaviour and energetics of a marine bird species, thick-billed murres (Uria lomvia). Methods We used temperature-depth-light recorders to examine strategies murres use to survive winter in the...

Drivers of polar bear behavior and the possible effects of prey availability on foraging strategy

Ron R. Togunov, Andrew E. Derocher, Nicholas J. Lunn & Marie Auger-Méthé
Abstract Background Change in behavior is one of the earliest responses to variation in habitat suitability. It is therefore important to understand the conditions that promote different behaviors, particularly in areas undergoing environmental change. Animal movement is tightly linked to behavior and remote tracking can be used to study ethology when direct observation is not possible. Methods We used movement data from 14 polar bears (Ursus maritimus) in Hudson Bay, Canada, during the foraging season...
