Polar bears threatened: Experience limited energy savings in summer

16 julio 2015

Some earlier research suggested that polar bears could, at least partially, compensate for longer summer food deprivation by entering a state of lowered activity and reduced metabolic rate similar to winter hibernation — a so-called ‘walking hibernation.’ But new research shows that the summer activity and body temperature of bears on shore and on ice were typical of fasting, non-hibernating mammals, with little indication of ‘walking hibernation.’img src=»http://feeds.feedburner.com/~r/sciencedaily/~4/zA1s3JEQJI8″ height=»1″ width=»1″ alt=»»/
