University of Illinois animal biology professor Julian Catchen, left, postdoctoral researcher Shane Campbell-Staton and their colleagues found genetic, regulatory and physiological signatures of natural selection in green anole lizards that survived a bout of extremely cold weather in South Texas. This material relates to a paper that appeared in the Aug. 4, 2017, issue of Science, published by AAAS. The paper, by S.C. Campbell-Staton at University of Illinois in Champaign, Ill., and colleagues was titled, "Winter storms drive rapid phenotypic, regulatory, and genomic shifts in the green anole lizard."
