Theses and Dissertations
Fragmentation of natural habitats is related to population decline in many species. The resulting small and isolated populations are expected to lose genetic variation at a rapid rate, which reduces the ability to adapt to environmental change. One concern is that small populations are more susceptible to emerging pathogens due to the loss of variation at immune genes. My dissertation examined the relative effects of gene flow, genetic drift and selection on immune genes in prairie-chickens (Tympanuchus cupido), a species that has undergone drastic population declines across their range. In the first chapter, I examined how artificial gene flow through …
