Status of Freshwater Mussels (Unionidae) in the French Creek Watershed, USA at the Onset of Invasion by Round Goby, <i>Neogobius melanostomus</i>

Freshwater mussels are an imperiled group of organisms that are vital to aquatic ecosystems. Services performed by freshwater mussels, coupled with their use for biomonitoring, make them an invaluable asset. <i>Neogobius melanostomus</i> (Round Goby), a recently introduced invasive speci...
