Colonization routes of the invasive aquatic snail Bithynia tentaculata L.
We are sampling from the three disjunct watersheds in the US with invasive populations and are currently seeking to widen our sampling of B. tentaculata from its native range in Europe.
To examine population genetic structure, seventeen microsatellite loci (tandem base repeats) from B. tentaculata were characterized through a collaboration with the Savannah River Ecology Laboratory. These loci are currently being genotyped on Bithynia from invasive populations. This poster summarizes the progress so far and our results by August 2010.
This project is a collaboration with other faculty in the Rivers Studies Center at UWL: Roger Haro and Greg Sandland as well as investigators at USGS: Rebecca Coles and Jenny Sauer.
