Project description:We sampled lake-type and riverine sockeye in the pristine natural habitats of Aniakchak National Monument and Preserve, Alaska USA.

Project description:We sampled lake-type and riverine sockeye in the pristine natural habitats of Aniakchak National Monument and Preserve, Alaska USA. Samples were taken on the same day and close proximite in time. We sampled 17 riverine individuals from Albert Johnson Creek and 13 individuals from Surprise Lake. cDNA from a single individual on the Cy5 was compared with a reference of aRNA on the Cy3.
Project description:Transcripts of the gill epithelium from three different stocks of Atlantic salmon (Salmo salar) migrating from freshwater river to lake (Saimaa stock, SS), brackish water (Neva stock, NS) or seawater (Teno stock, TS) were compared at three successive developmental stages (parr, smolt and postsmolt) using the 16K GRASP cDNA microarray platform.
Project description:We examined adaptive morphological divergence and epigenetic variation in genetically impoverished asexual populations of a freshwater snail, Potamopyrgus antipodarum from distinct environments. These populations exhibit environment-specific adaptive divergence in shell shape and significant genome wide DNA methylation differences among differentially adapted lake and fast water flow river populations. The epigenetic variation correlated with adaptive phenotypic variation in rapidly adapting asexual animal populations. This provides one of the first examples of environmentally-driven differences in epigenetics that associates with adaptive phenotypic divergence.
