Phylogeography and DNA barcoding Gammarus species

Phylogeography and DNA barcoding Gammarus species

With Jenny Rock, Nia Whitely, and collaborators I have investigated the phylogeography and ecological adaptation to different water temperature environments in Gammarus duebeni . This species shows divergence between freshwater and marine forms (subspecies) and its enormous lattitudinal range has interesting applications from the perspecitive of muscle protein adaptation to different temperature regimes. DNA barcodes are a powerful tool for investigating Gammarid diversity. The images are our cover of Systematics and Biodiversity, and a beautiful G. roeselii photo (which was one of our study species). See Gammarus papers.
