It’s no secret that fish have an impressive ability to survive in extreme environments - from icy cold depths to scorching hot deserts. Now, a new study published in Nature Ecology and Evolution has shed light on the genomic mechanisms that allow fish to adapt to these extreme environments. Researchers from the University of Washington studied two species of fish, the Arctic charr and the desert pupfish, to identify the genes that allow them to survive in their respective habitats. The results of the study showed that both species had adapted to their environment in similar ways, with the Arctic charr showing more genetic adaptation to the cold and the desert pupfish to the heat. These findings provide an important insight into how fish can survive in extreme environments, and could potentially lead to advances in conservation efforts to help protect species in these habitats.
