Grizzlies show remarkable gene control before and during hibernation

Researchers conduct a cardiac ultrasound on a groggy bear during hybernation.Being a human couch potato can greatly increase fat accumulation, hasten the onset of Type II diabetes symptoms, result in detrimental blood chemistry and cardiovascular changes, and eventually, bring about one’s death.

Large hibernators such as bears however have evolved to adapt to and reverse similar metabolic stressors they face each year before and during hibernation to essentially become immune to these » More …

Big data on big animals

Work at the WSU Bear Research, Education, and Conservation Center goes well beyond important things like enrichment programs and energy-monitoring collars. WSU scientists are looking at the genomic level to try and determine the myriad ways that bears adapt to their climate.

Joanna Kelley, an evolutionary geneticist and assistant professor in the School of Biological Sciences, said for the last two years, her lab has collected three different samples from six of the bears three times a year. Each sample has over 200 million pieces of data, giving them 10.8 billion pieces of data to wade through each » More …
