Individuality in Rodents: Research in the News

Being part of the crowd is what makes you unique. Say what?...

That’s the bottom line of a multi-year study I did with Dan as part of my dissertation research. We looked at eight different species of social ground-dwelling rodents, including marmots and their close cousins prairie dogs and ground squirrels. We found that as social group size increases over evolutionary time, so does the degree of individuality in the animals’ voices. Our study is the cover feature of the latest issue of Current Biology.

Our study has been covered in popular press outlets, including:
