Light and dark examples of Holbrookia maculata. Photo courtesy Simone Des Roches.So, remember my posts back in February about three lizards that evolved lighter coloration after colonizing the white gypsum sand of White Sands, New Mexico, and about Erica Bree Rosenblum, the University of Idaho biologist who has studied them for most of her career? Sure you do. Well, Rosenblum's grad student (and my former office-mate and continuing friend) Simone Des Roches has started a blog about her work at White Sands this spring and summer. Go check it out for the latest on Holbrookia maculata, and for Simone's fantastic photography of the beautiful desert landscape and its inhabitants.
