1 Stream size and surface geology are the two major environmental features thai control the distributions of the thirty‐four species of unionid mussels living in the streams of southeastern Michigan. 2 Surface geology, a previously unrecognized factor in the ecology of freshwater mussels, acts lo regulate the hydrology, slope and turbidity of streams in the study area. 3 Reciprocal averaging ordinations are used to aid the description of the habitats occupied by each mussel species.
