A mathematical analysis of evolutionary rescue and niche construction
… by undergoing adaptation. This process, evolutionary rescue, entails a population approaching extinction until an adaptive mutation appears and subsequently establishes by escaping stochastic loss. While most models of evolutionary rescue emphasize mutations that allow organisms to …

Adaptation in a Changing World: Evolutionary mechanisms of salt tolerance in a coastal amphibian
In order to predict evolutionary outcomes of environmental change on populations in nature, we need an improved understanding of the biological mechanisms that affect whether organisms will adapt to a changed environment. This dissertation capitalizes on the unlikely discovery of a freshwater …

Four problems in nonlinear Earth system dynamics
… Using this observation, the existing theory of “evolutionary rescue”, mathematics surprisingly like the global glaciation problem, and agent-based simulations, I argue that rate-induced collapse in response to environmental change may be a common feature of evolutionary-ecological systems on a …
