Shades of Bumpus: Polar Vortex-Induced Natural Selection on Cold Tolerance in the Green Anole

Shane Campbell-Staton had fortuitously measured the thermal physiology of a number of populations of the green anole, Anolis carolinensis, the summer before 2014’s Polar Vortex. So, he went back and examined the survivors. And sure enough, in the most southerly populations, those most strongly affected by the cold snap, natural selection had occurred. Shane tells Scientific American all about it in this podcast. The nifty figure above comes from the University of Illinois’ press release.

 

About Jonathan Losos

Professor and Curator of Herpetology at the Museum of Comparative Zoology at Harvard University. I've spent my entire professional career studying anoles and have discovered that the more I learn about anoles, the more I realize I don't know.
