Nested clade analysis of geographic structure in the morphologically variable Themeda triandra in South Africa
… H6 inferred to be the ancestral haplotype. A nested clade analysis was performed with the results used to infer the geographic structure of T. triandra within South Africa. Significant results showed that there was restricted gene flow with nested clades involving the three Free State …

Genetic Considerations for the Conservation and Management of Yellowstone Cutthroat Trout (Oncorhynchus clarkii bouvieri) in Yellowstone National Park
… assignment tests, coalescent theory, and nested clade analysis) analytical approaches to describe the population genetic subdivision of cutthroat trout spawning populations in Yellowstone Lake and to identify genetically distinct population segments throughout Yellowstone National Park. …

Biogeography of Montane Mammals on the Colorado Plateau and Adjacent Regions
… approaches (parsimony and likelihood) as well as nested clade analysis. Results support previous documentation of a major east-west phylogeographic break occurring between populations southeast of the Colorado River (eastern Arizona, Colorado, Wyoming and New Mexico) and all other western …

Gene Flow and Dispersal Among Populations of the Stonefly <i>Peltoperla tarteri</i> (Plecoptera: Peltoperlidae) in the Southern Appalachians
… was generally high within and among drainages. Nested clade analysis indicates that historical fragmentation and range expansion coupled with contemporary gene flow explain the present day pattern of genetic variation in <i>P. tarteri.</i> In order for these historical patterns to have such a …

Evolution of Endosperm Starch Synthesis Pathway genes in the Context of Rice: Oryza sativa) Domestication
… <italic>Wx</italic> in rice are included in the analysis as well. The difficulty of detecting selection is often caused by the complex demographic history of a species. Genome-wide sequence data in a species would mainly reflect its demographic history. I have compared the pattern of nucleotide …

Phylogenetic History, Morphological Parallelism, and Speciation in a Complex of Appalachian Salamanders (Genus: Desmognathus)
Understanding the mechanisms that generate shared morphologies across closely related taxa is important when identifying distinct evolutionary lineages using morphological characters. Desmognathus salamanders are an ideal group for testing hypotheses concerning the correlation between morphological …

Historical Responses Of Marine Turtles To Global Climate Change And Juvenile Loggerhead Recruitment In Florida
Marine turtle conservation is most successful when it is based on sound data incorporating life history, historical population stability, and gene flow among populations. This research attempts to provide that information through two studies. In chapter I, I identify historical patterns of gene …

Evolution in Neotropical Herpetofauna: Species Boundaries in High Andean Frogs and Evolutionary Genetics in the Lava Lizard Genus Microlophus (Squamata: tropiduridae): A History of Colonization and Dispersal
… within- and between-island biodiversity in this clade of lizards; confirmation of these explanations with independent data will have management implications for conserving the unique patterns observed in the Galapagos biota, but also the processes that generated these patterns.</p>
