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 ti
Declining Arctic sea ice is increasing polar bear land use. Polar bears on land are thought to minimize activity to conserve energy. Here, we measure the daily energy expenditure (DEE), diet, behavior, movement, and body composition changes of 20 differe
Experienced bear hunters say that on a warm day a man can run down a polar bear even on rough-surfaced ice. With their excellent cooling ability by panting, dogs can overtake a bear on ice. These examples illustrate diversity and limitations in thermal regulatory devices and behavior. View ...
we were generally able to track down the bear’s identity by linking the record to previous or subsequent observations of the same individual (supplementary Data Records). Alternatively, circumstantial evidence was used to ascertain whether the presence of a bear was unique in a particular year, ...
1980s. Their most recent population estimate indicates thepolar bearpopulation has declined by about 40 percent over the past decade. It has been difficult, however, for researchers to study the fundamental biology and behavior of polar bears in this very remote and harsh environment, Pagano said...
Tundra vehicle approaches were manipulated to determine effects on polar bear behavior, and to investigate any variables that significantly affected response, including habituation. A response was defined as any sudden whole body movement or change in position or behavior at the time of approach. A ...
