A new invasive species in Lake Erie and other Great Lakes that is also making its way into the Finger Lakes region, H. anomala is the first Mysid to become established in Lake Erie. H. anomala’s feeding selectivity carries the potential for trophic cascade effects as their predation may limit the number of important grazer species. However, their adaptive omnivorous diet may allow them to shift their diet to include a larger portion of algae, occupying an intermediate feeding niche. We are examining diet selectivity of this species in laboratory and field experiments. (2009-2010)
