Species are threatened daily by human activities, the most devastating of which are habitat destruction and fragmentation, which can drastically decrease population size. One of the most severe consequences of these decreases in population sizes is the decrease in genetic diversity, which may affect fitness and reduce the adaptive potential of natural populations. These consequences, however, may not affect all species equally due to their past evolutionary history, migratory habits, and current demographic factors. This study focuses on the potential role of migratory habit on the maintenance of genetic diversity of avian species that live in a fragmented habitat. The mitochondrial control region sequences of six Passerine species that breed within the Oak Openings area of Northwest Ohio were compared based upon the species' migratory habit while controlling for the effects of phylogenetic history. Consistent with results from previous studies, species that migrate long distances showed higher levels of genetic diversity (higher numbers of haplotypes and average p-distance) than species that do not migrate. An analysis of variance based on within-population estimates of DNA sequence variation revealed a significant contribution of both phylogenetic history and migratory habit to species' genetic diversity. Overall, 50.72% of the total variation observed across multiple species could be explained by differences in migratory habit. These results emphasize the important role of migratory habit in determining overall levels of genetic diversity, an important consideration for the management and conservation of species that breed within fragmented habitats.
