ON THE PROVENANCE OF AN ORCONECTES POPULATION IN THE JAMES RIVER BASIN, VIRGINIA

We investigated the origin of a Virginia population of Orconectes crayfish population found in the upper James River and a small portion of the upper Roanoke River basins in western Virginia. This population was first noticed by several researchers, and although the precise identity and provenance of the population was unclear, genetic evidence suggested links to Orconectes populations in the Ozark region of Missouri and Arkansas. We tested the hypothesis that it was native to both regions or native to one region and introduced to the other using genetic data. We sequenced a portion of the mitochondrial cytochrome oxidase I gene and NADH dehydrogenase 2 gene from individuals across the known range in Virginia, and compared them to sequences from several Orconectes species from Arkansas and Missouri. For both genes, the Virginia populations were completely devoid of sequence variation, strongly suggesting an introduced population of recent origin. These sequences were closest to samples of Orconectes ozarkae from south-central and southwestern Missouri.
