POPULATION GENETIC STRUCTURE AND PATERNITY OF THE THREERIDGE MUSSEL (AMBLEMA PLICATA) IN SOUTHEAST OKLAHOMA ASSESSED USING MICROSATELLITES.
Several anthropogenic factors have led to substantial declines in North America’s freshwater mussel populations over the last century. A greater understanding of mussel dispersal abilities and population structure is imperative to improve conservation strategies. Since impoundments restrict fish movement and reduce gene flow in mussels, we predicted that genetic structuring may exist between populations upstream and downstream of impoundments. We evaluated genetic structure and paternity of a common, host-generalist mussel species (Amblema plicata) in the Little River in southeast Oklahoma using nine polymorphic microsatellite loci. We genotyped a total of 270 individuals from nine mussel beds distributed throughout the Little River. The programs STRUCTURE and ML-Relate were used to examine genetic structure and relatedness (i.e. paternity), respectively. Results from this study will have important conservation implications by providing a better understanding of the dispersal capabilities of host-generalist mussel species and the number of males contributing to broods. Understanding mussel population structuring can improve mussel conservation strategies by informing management where mussels should be reintroduced and which mussel beds are the most genetically diverse, and therefore of potential priority for protection.
