Historic mussel distribution for Cahaba, Coosa, and Duck River Basins 1800 - 1985

Metadata Updated: August 15, 2019

The University of Tennessee at Chattanooga (UTC), in partnership with the Tennessee Aquarium, Inc. (TNAQ) and the Tennessee Aquarium Research Institute (TNARI), has amassed a sizable amount of historical data on imperiled freshwater mussels from the region. Mussels are one of the building blocks of the food web because they serve as food for fish, turtles and aquatic mammals. In addition, mussels also benefit the environment by acting as filter feeders and in turn, they clean our drinking water by cleaning our rivers. Thus, they make excellent biological indicators and the loss of mussels from rivers and streams can be disastrous for aquatic ecosystems. Recently, mussels are receiving a great deal of attention from the scientific community primarily because of their niche and their sensitivity to anthropogenic effects. However, before land-managers and other natural resource professionals can successfully develop adaptive conservation and management strategies, scientists must first effectively study biological diversity in order to understand which species are present and how they are distributed. Hence, most natural resource professionals have difficulty in developing successful management plans because of the paucity of distribution data that are available to the public-at-large. Databases concerning freshwater mussels are few, and those that do exist are often overly complex and fail to convey the information in a timely and no nonsense manner.
