This dissertation focused on the insect order Plecoptera, and hypothesized that Allocapnia recta populations would have lower genetic diversity than Leuctra tenuis between adjacent Chagrin and Grand Rivers due to wing structure and season of terrestrial adult emergence. Genetic variations within the 16s rRNA region of mtDNA in A. recta, a winter emerging adult with rudimentary wing structure, and L. tenuis, a summer emerging adult with fully developed wings, were compared and revealed significant genetic variability between A. recta samples from the two rivers (FST = 0.20) but not between L. tenuis samples (FST = 0.07). Further genetic variation investigation …
