Co-occurrence of fish and mussel species in rivers upstream from three eastern Kansas reservoirs Brian Theel North America has the greatest freshwater mussel diversity in the world . Mussels are a very endangered group. In this study, I compared the presence or absence of mussels to their known hosts. During the days of June 8 to July 22 of 2000 we sampled 36 sites on three eastern Kansas rivers upstream from there reservoirs. I surveyed literature to discuss known hosts for mussels present and now extirpated from the Marais des Cygnes River.
Future plans are to finish the data analysis for the rest of the sites on the three rivers.
