Title:  Disentangling the Roles of Form and Motion in Fish Swimming Performance

Abstract:  A central theme of comparative biomechanics is linking patterns of variation in morphology with variation in locomotor performance. This presents a unique challenge in fishes, given their extraordinary morphological diversity and their complex fluid-structure interactions. This challenge is compounded by the fact that fishes with varying anatomy also use different kinematics, making it difficult to disentangle the effects of morphology and kinematics on...

Title:  Causes and Consequences of Coexistence in the Vachellia drepanolobium Ant-Plant Mutualism

Abstract:  This thesis focuses on a mutualism between the East African acacia tree Vachellia drepanolobium and the species of canopy-dwelling ants that inhabit it.  The tree provides the ants with nesting space in the canopy and extra-floral nectar, and in return the ants defend the tree from herbivores. Several different ant species compete vigorously with each other for this canopy nesting space.  Despite this,...

Title:  Comparative and Population Genomics of Host-Pathogen Co-Evolution in Birds

Abstract:  Infectious disease produces some of the strongest selective forces on natural populations across the tree of life. The signatures of pathogen-mediated evolution on host genomes have been described for several model organisms, but few studies of non-model organisms have detected such signatures beyond candidate loci such as MHC genes or toll-like receptors. In my dissertation I use population genomics and comparative genomics to study the dynamics of...

Title:  Anatomical Patterns, Kinematics, and Propulsive Strategies of Foot-Based Swimming Birds

Abstract:  Within the diversity of birds, numerous lineages have colonized aquatic environments. Birds that swim by paddling with their feet must generate propulsive forces underwater using legs originally adapted for walking. Despite this challenge, foot-propelled swimming has evolved independently in at least six avian lineages (including in cormorants, grebes, and loons) and to varying degrees of specialization....

Title:  Phenotypic Variation and the Behavioral Ecology of Lizards

Abstract:  Behavioral ecology is the study of how animal behavior evolves in the context of ecology, thus melding, by definition, investigations of how social, ecological, and evolutionary forces shape phenotypic variation within and across species.  Framed thus, it is apparent that behavioral ecology also aims to cut across temporal scales and levels of biological organization, seeking to explain the long-term evolutionary trajectory of populations and species by...
