Phylogeography Of Two Closely Related Anurans, The Relict Leopard Frog (Rana Onca) And Lowland Leopard Frog (Rana Yavapaiensis), Viktoria Hemmings
UNLV Theses, Dissertations, Professional Papers, and Capstones
I investigate the phylogeography of the relict and lowland leopard frogs (Rana onca; R. yavapaiensis) inhabiting the Mojave and Sonoran deserts. In Chapter 1, I summarize literature describing taxonomy, phylogenetics, and the possible effects of Quaternary climate change on distribution. Examples of phylogeographic patterns from generally co-distributed organisms are provided to develop background for interpreting the structure. In Chapter 2, I investigate the phylogeography of these frogs using mitochondrial DNA data. The analysis supports a previously determined phylogenetic break between taxa however further dividing R. yavapaiensis into two lineages. I estimate a possible Early Pleistocene divergence of R. onca and …
Phylogeography And Landscape Genetics Of The Flammulated Owl: Evolutionary History Reconstruction And Metapopulation Dynamics, Markus Mika
UNLV Theses, Dissertations, Professional Papers, and Capstones
Taxa occur across ever changing landscapes on different spatial and temporal scales. Choosing the appropriate scale for collecting data and drawing inferences is critical for understanding the history of a species and its populations. Here, I describe research in which I investigated phylogenetic patterns and population genetics for Flammulated Owls (Otus flammeolus) representing 14 localities from throughout the species' distribution, and compared regional landscape features with the distribution of genetic diversity. This small, insectivorous owl migratory (Family Strigidae) breeds in western conifer and deciduous dry forests of the mountains from southern Mexico to British Columbia. Sedentary populations are found in …
