Book Description
Understanding the molecular basis of adaptations in coevolving species is an important goal of evolutionary biology. Venom in predators and venom resistance proteins in prey are examples of such coevolving molecular phenotypes. In my thesis, I investigate two molecular traits that are important in coevolutionary interactions between the northern Pacific rattlesnake (Crotalus oreganus oreganus) and its primary prey item, the California ground squirrel (Otospermophilus beecheyi). In Chapter 1, I briefly introduce the topics of my thesis research by reviewing how population-level variation in venom protein composition and metalloprotease activity has been established in C. o. oreganus and that there is evidence of O. beecheyi evolving resistance in response to the sympatric predator. In Chapter 2, I further characterize venom activity through in vitro tests of enzymatic activity to assess functional differences between 12 populations of C. o. oreganus and investigate what the possible causes of this variation might be. My results support the conclusions of other studies that there is population-level variation in venom function but the proximate and ultimate causes for this functional variation remain unclear. In Chapter 3, I generate a transcriptome for O. beecheyi and run this transcriptome through a series of filters to identify genes that code for potential venom resistance proteins. My work provides a reference transcriptome for future work and I identify 5 proteins that pass all filters for potential resistance proteins. Overall, my thesis provides more detail on functional variation within rattlesnakes and lays out a genetic framework for the evolution of resistance proteins within ground squirrels. In combination my work sets the stage for future detailed work focused on understanding coevolutionary interactions at the molecular level between ground squirrels and rattlesnakes.

Geographic Variation in Behavior

Book Description
Studies of animal behavior often assume that all members of a species exhibit the same behavior. Geographic Variation in Behavior shows that, on the contrary, there is substantional variation within species across a wide range of taxa. Including work from pioneers in the field, this volume provides a balanced overview of research on behavioral characteristics that vary geographically. The authors explore the mechanisms by which behavioral differences evolve and examine related methodological issues. Taken together, the work collected here demonstrates that genetically based geographic variation may be far more widespread than previously suspected. The book also shows how variation in behavior can illuminate both behavioral evolution and general evolutionary patterns. Unique among books on behavior in its emphasis on geographic variation, this volume is a valuable new resource for students and researchers in animal behavior and evolutionary biology.
