My students (link) and I seek to uncover the links between genetics, physiology, reproductive ecology using various model systems including garter snakes, painted dragons, and cane toads.
Our interests include:
Sexual selection and sexual conflict
The evolution of sexually-dimorphic behavior and morphology
The evolution of life history traits—especially physiological underpinnings of sex-specific and alternative reproductive tactics effects on ageing
For example, we work to understand:
How and which proximate mechanisms mediate trade-offs between pre- and postcopulatory sexually selected traits. Trade offs between traits that evolve in response to these two episodes of selection underlie the emergence of alternative mating and life history strategies.
How and why wild organisms age and fitness consequences of aging on sexual selection in wild populations.
Why the interests of the sexes may be incongruent, how trait function generates sexual conflict and how sexually antagonistic coevolution has shaped the most intimate interaction between the sexes; copulation and genital coevolution.
How environmental factors influence physiology and behavior in ways that may cause variation in mating system dynamics among populations.
