When It Comes To Survival Of The Fittest, Stress Is A Good Thing

In a study led by Michigan State University (MSU) and the University of Guelph (Canada), researchers showed for the first time how females use social cues to correctly prepare their offspring for life outside the nest. The results, published in the current issue of Science, confirm that red squirrel mothers boosted stress hormone production during pregnancy, which increased the size and the chances of survival of their pups.

"Natural selection favors faster-growing offspring, and female red squirrels react accordingly to increase their pups’ chances of survival," said Ben Dantzer, formerly with MSU’s zoology department and now a postdoctoral researcher at the University of Cambridge (United Kingdom). "Surprisingly, squirrels could produce these faster growing offspring even though they didn’t have access to additional food resources."
