I sampled Long Point Bay (LPB), Lake Erie, in 2009 to quantify changes in SAV communities and densities of zebra mussels since the peak of the latter in the early 1990s, and modeled influences of year, water depth, and substrate type on the probability of SAV detection. Robin detected that carrying capacity of LPB for waterfowl and other fish and wildlife that use and eat SAV and mussels increased during the mid-1990s, but has since decreased. Robin is employed as a Biologist at Predator Bird Services where he clears wildlife dangers at airports and landfills using trained birds of prey.
