Abstract

North America’s freshwater mussels are widely regarded as one of the most diverse and imperiled groups on earth, and many of the continent’s ~ 300 Unionidae and Margaratiferidae are drainage or regional endemics. Although Ligumia recta is currently widespread and stable in the Mississippi Basin, recent surveys suggest it is extirpated from the Pearl River drainage and only small populations persist in isolated Mobile River Basin tributaries. We compared 504 base pairs of the cytochrome c oxidase 1 mitochondrial gene from two Mobile Basin L. recta specimens and found that the Mobile Basin appears to support an evolutionarily significant genotype that could warrant recognition as a cryptic and highly imperiled taxon. Genetic data are beginning to reveal the extent and magnitude of recent biodiversity losses in the southeastern US, and moreover, these data will be critical to tailoring conservation and management strategies.
