René Clark (Ph.D. candidate) and co-authors from the Pinsky Lab, Montclair State University, Columbia University, UCLA, Shiga University (Japan), and Visayas State University (Philippines) published a paper in Proceedings of the Royal Society B investigating the relationship between selection, gene flow and genetic drift across the species range of Amphiprion clarkii (the yellowtail clownfish). Using RNAseq data from populations near the range center (Indonesia & the Philippines) and the northern range margin (Japan), they found signs of local adaptation to cold temperatures at the range edge, despite strong genetic drift and gene flow from lower latitudes. Many of the targets of selection were found in genes involved in acclimation to cold stress, including protein turnover, metabolism, cell structure, and cell death, and may point to an important link between plastic and evolutionary responses involved in thermal adaptation.
