The Ecology, Evolution, and Conservation of Stone Oaks (Lithocarpus)
This thesis investigates how plant traits, evolutionary history, and environmental conditions shape the ecology of Stone Oaks (Lithocarpus), a diverse but geographically restricted tropical clade. Chapter 1 introduces Lithocarpus as a model clade for investigating diverse ecological and …

Stochastic many-body problems in ecology, evolution, neuroscience, and systems biology
… of biology dominated by strong fluctuations: The evolutionary history of the genetic code, spatiotemporal pattern formation in ecology, spatiotemporal pattern formation in neuroscience and the robustness of a model circadian rhythm circuit in systems biology. In the first two research chapters, I …

Marine carbohydrate-active enzymes illuminate microbial ecology, evolution, and carbonate precipitation
… of life on Earth and billions of years of the evolutionary history of microbial life. And the gene sequences of marine CAZymes preserve a yet-unexplored record of microbial evolution that can be constrained by the fossil record of major algal lineages. This thesis explores marine …

The ecology, evolution and persistence of an obligate, one-on-one mutualism
Some of the most celebrated examples of coevolution are found amongst obligate, one-on-one mutualisims (e.g. fig and yucca pollination systems). Although obligate, one-on-one mutualisms may be common among intimate, endosymbiotic organisms, they are apparently uncommon between free-living or …

Genetic Diversity of Blue Wildebeest (Connochaetes taurinus) in the Liuwa Plain of Zambia
… organisms to answer questions concerning ecology, evolution, and conservation. Analysis of SNP allele frequencies can provide insight into the amount of genetic diversity present in a population, connectivity between populations, and historical demographic changes. The blue wildebeest …

The Resource Environment and Microbial Associations Mediate Adaptation to Environmental Heterogeneity in Drosophila Melanogaster
… to heterogeneity remains a major focus of evolutionary biology. The ability to observe the genomic and phenotypic evolution of populations over rapid timescales has enabled a deeper exploration into the role particular environmental variables have on a population’s response to selection. …

Multiple Paternity of Caretta Caretta within the Northwestern Atlantic Ocean Population on Wassaw Island, Ga
… efforts. Mating systems can impact the ecology, evolution, effective population size and genetic variability of a species. Polyandry, resulting in multiple paternity can influence the maintenance of genetic variation within a population. Within Testudines, the frequency of multiple …

Topography as a determinant of range extent and overlap : a species level phylogenetic reconstruction and geographical range analysis of Syncarpha (Asteraceae)
… has several implications for questions in ecology, evolution and conservation biology. The Cape Floristic Region of South Africa is noted for its remarkably high geographic species turnover, often attributed to the exceptional environmental heterogeneity of the region. The complex and …

Indirect genetic effects of rhizobium symbiosis plasmid on legume-grass dynamics
… This study indicates potential for rapid evolution via HGT in bacterial communities to have indirect effects on other species via their symbiosis with legumes.

Consumer nutrient stoichiometry : patterns, homeostasis, and links with fitness.
The linkages between food webs and nutrient cycles are heterogeneous and often influenced by human activities. Ecological stoichiometry provides one framework for understanding and predicting these linkages. Yet, as it has been extended underlying assumptions are often not evaluated. This …

Paternity and father-offspring relationships in wild chimpanzees, Pan troglodytes schweinfurthii.
Hamilton's seminal theory of kin selection asserts that because relatives share a certain proportion of genes, individuals can increase their inclusive fitness by helping and/or not harming kin, as long as the benefits to kin outweigh the costs to the individual. We would expect animals to attain …
