Seminar: Thermal acclimation and adaptation in fish
Individual fish can respond to warming through acclimation of their biochemistry and physiology to be better suited to the new temperature. Populations of fish may additionally evolve across generations. We study these processes in zebrafish and examine how acclimation capacity can differ between populations living in different thermal environments. To quantify the rate and scope of adaptation to warming, we conducted a large artificial selection experiment spanning six generations. We show that thermal tolerance can evolve over relatively few generations, but the magnitude of the increase is small and unlikely to keep up with the current rate of climate change.
Dr. Fredrik Jutfelt, Associate Professor in Biology at the Norwegian University of Science and Technology, will be presenting this seminar. Hosted by Mike Nishizaki.
