Costs and Benefits of Intrasexual Aggression in Females: an Experimental Approach
(2009)A long-held assumption in animal behavior is that females and males differ fundamentally in their mating strategies. Females are thought to be more choosy because female reproduction typically is limited by parental investment. ... -
Evaluating the Hominin Scavenging Niche through Analysis of the Carcass-Processing Abilities of the Carnivore Guild
(2008-08-08)Humans are more carnivorous than other hominoids. It has been hypothesized that, during the evolution of this increased carnivory, hominins transitioned through a scavenging niche made viable by certain carnivoran taxa ... -
Evolutionary Relationship between Life History and Brain Growth in Anthropoid Primates
(2008-09-18)The pace of life history is highly variable across mammals, and several evolutionary biologists have theorized that the tempo of a species' life history is set by external factors. These factors, such as food availability ... -
Functional and Evolutionary Genetics of a Wild Baboon Population
(2010)Although evolution results from differential reproduction and survival at the level of the individual, most research in evolutionary genetics is concerned with comparisons made at the level of divergent populations or species. ... -
Life History Parameters and Social Associations of Female Bottlenose Dolphins (Tursiops Truncatus) in North Carolina, USA
(2008-04-25)In this study, I describe the seasonality of reproduction in bottlenose dolphins by examining data from stranded animals, photographic surveys and focal follows. I examined inter-birth intervals from focal follows of known ... -
Reading the Book of Life: Contingency and Convergence in Macroevolution
(2008-01-01)This dissertation explores philosophical problems in biology, particularly those relating to macroevolutionary theory. It is comprised of a series of three papers drawn from work that is currently at the publication, ... -
THE FORM AND FUNCTION OF SCALLOP MANTLE EYES
(2010)Scallops, a family of swimming bivalve mollusks, have dozens of eyes arrayed along the edges of their valves. Relatively little is known about the form and function of these unusual eyes. To learn more about them, we studied ... -
The Genetic Architecture of Hybrid Male Sterility in the Drosophila Pseudoobscura Species Group
(2009)Biodiversity is generated by the process of speciation. Because biological species are defined as populations that are unable to exchange genes with one another, the study of the evolution of reproductive isolation occupies ...
