Genetics and Genomics

USGS geneticists work to provide answers to questions of genetics for use in making sound management decisions on fish and wildlife, including their habitat and conservation. More about USGS Genetics and Genomics

Ecological stability in the Laurentian Great Lakes has been altered by nonindigenous species, such as the round goby Neogobius melanostomus and dreissenid mussels, and by declines in native amphipods Diporeia spp. We evaluated whether these changes could influence diet overlap between three benthivorous fishes (slimy sculpin Cottus cognatus, deepwater sculpin Myoxocephalus thompsonii, and round goby) and whether predation on eggs of native species was occurring.
