Abstract Details

2017, Doctor of Philosophy, Miami University, Ecology, Evolution and Environmental Biology.
Populations can respond to changes in their environment through plastic development, dispersal, and/or adaptation. Each of these processes can interact and influence the genetic biodiversity and whether it can persist under selection pressures. However, the nature of these interactions is not well understood, and there is a lack of understanding of the complex responses populations have to a changing environment. In central and northern Michigan two distinct mitochondrial lineages of the white-footed mouse, Peromyscus leucopus (Upper Peninsula; UP and Lower Peninsula; LP), appear to have responded to climate change differently. As the climate of the Great Lakes region warmed, one lineage (UP) dispersed into new territory over the past 30 years while the other (LP) did not. These two lineages provide an opportunity to investigate the complex responses a population can have with the surrounding environment. To understand how these different responses influence the genetic and phenotypic diversity of the current distribution of P. leucopus, I sampled 11 populations across both lineages and collected genetic and geometric morphometric data. In the following chapters these data are examined under different contexts to create a comprehensive picture of Great Lakes P. leucopus populations. In summary, the population network of the white-footed mouse has responded to environmental change over the past thirty years by maintaining genetic connectivity facilitated by human transport and potential phenotypic plasticity.
