AB: Appreciation of genetic diversity in unionids is essential to their preservation. Understanding how habitat perturbations, particularly those that fragment populations, affect this genetic diversity will provide information for better management of their natural habitats. We will examine genetic diversity and relatedness within a common mussel species, Amblema plicata, from three rivers in the Ouachita Highlands of southeastern Oklahoma that are fragmented to varying degrees. We sampled A. plicata tissue from ten sites each in the Little, Glover and MT. Fork Rivers. At each of ten sites per river, mussels were sampled from 15, randomly placed, 0.25m2 quadrats. Tissue samples consisting of 20-40 micrograms of mantle tissue were clipped from a minimum of 30 individuals per site. A subsample of mussel individuals was taken from each site for shell thin-sectioning to determine age. Microsatellite markers will be used to examine both genetic diversity and relatedness of A. plicata within and between sites. This will enable us to determine the impacts of impoundments on gene flow.
