We have been working with Michael Tobler‘s lab at Kansas State University to understand the molecular basis of adaptation to hydrogen sulfide springs. We sequenced and analyzed transcriptomes from multiple populations of sulfide spring fishes. We sampled fish in the genus Poecilia from mulitple, replicated clear and sulfidic springs. The results of the study have recently been published in Molecular Biology and Evolution! A variety of news sources have covered our findings, including Scientific American Español.
