Abstract : Literature and field data were synthesized to prepare a community model for thick-shelled unionid mussels (Quadrula, Amblema, Plectomerus, Megalonaias, Obovaria, and Obliquaria, etc.) that are found in gravel substrate in medium- to large-sized rivers. This model, developed for use with the Habitat Evaluation Procedures of the US Fish and Wildlife Service, can be used for general planning purposes, and to gain a a more complete understanding of the biology and ecology to thick-shelled freshwater mussels. The distribution of these species, with respect to the following physical and chemical variables, is reviewed: water velocity, particle type, sediment stability, deposited sediment retained annually, minimum depth, maximum sustained water temperature, minimum sustained dissolved oxygen, and calcium hardness. Physical, chemical, and biological characteristics of large river systems where these organisms are found are reviewed. The biology and ecology of freshwater mussels, including feeding, locomotion, behavior, reproduction, and early development, are discussed. Keywords: Habitat; Marine biology; Ecology; Environmental impact.
