Lucania goodei, Lucania parva
The goals of these studies are to explore the mechanisms that may account for evolutionary divergence of adaptive osmotic physiologies among taxa that occupy different osmotic niches. In a common-garden environment, we track genome expression responses to hyper-osmotic (brackish water) challenge during a time-course of acclimation, and contrast these responses between species. We seek to identify mechanisms that facilitate osmotic acclimation that are evolutionarily conserved between basal and derived physiologies, and also to identify mechanisms that are uniquely derived in alternate osmotic environments.
