There is a growing consensus that humans are the primary transporters of spiny water flea, and it is important to understand its role and effects on the aquatic ecosystem (Weisz & Yan, 2010). Evolution of Bythotrephes traits, however, depends on the presence and magnitude of quantitative genetic variation, which could change within or across years. Great Lakes Distribution: The spiny water flea is found in all of the Great Lakes and a number of inland waters. There is a growing consensus that humans are the primary transporters of spiny water flea, … Oct 08, 2012 — Discovery of the spiny water flea in Lake George has heightened worries that the invasive species will eventually move into Lake Champlain. We do so by presenting the results of the work conducted by researchers in the Canadian Aquatic Invasive Species Network (CAISN), and several of their American and European collaborators over the past half decade.
