Squirrels squeezed by climate change
Edmonton, AB — Rocky Mountain ground squirrels are hibernate longer due to climate change and this is affecting their survival rates according to a recent study completed at the University of Alberta.
An international research team examined data on a population of ground squirrels living in the foothills of Alberta and found that a trend of late-spring snowfalls has delayed the animals’ emergence from hibernation by 10 days over the last 20 years.
...Research shows the food supply is only three to four months long and they have a hibernation period of eight to nine months...“Our data show that over the life of the study, the survival rate of adult females has fallen by 20 per cent, and much of this could be due to late emergence from their burrows brought on by late-spring snowfalls,” said Lane.
