North American freshwater crayfish are known to exhibit great biodiversity; however, the interrelationships between populations are still being examined. This project investigated three populations of O. virilis from Massachusetts using four microsatellite markers. I hypothesized that there would genetic differentiation among the populations due to the high amount of isolation among crayfish populations and its low dispersal rates. Based on Fst and Rst, the results from this study supported the hypothesis; however several factors should be considered including the small sample size and high failure rate for amplification. Further investigation to analyze the population structure of crayfish is recommended, particularly using microsatellite loci.
