Human activities often dominate ecological processes and can cause rapid evolution on ecological time scales. My research is focused on developing theoretical models to investigate how ecological and evolutionary processes interact in response to large-scale, anthropogenically-driven global change, particularly in marine systems. In addition to exploring how global change affects population persistence and community structure, this research investigates topics where evolution is vital to understanding ecological dynamics and conserving biodiversity. Projects include:
Movement between locations might either impede local adaptation or help maintain a population at a given location, depending on factors such as the relative population sizes across locations, differences in selection regime between locations, the amount of connectivity between locations, and temporal in variability selection. While these factors have been explored separately, how these factors interact to determine the effect of gene flow on local adaptation and population dynamics remains less well understood. This project will develop a suite of models to investigate how spatial and temporal variation in selection and migration interact to determine the effect of gene flow on local adaptation and population dynamics. These models will be based on salmon that receive inputs from aquaculture and hatchery programs, as the scale and variety of such programs provide a data-rich source of accidental experiments in exchange between populations that experience differential natural and artificial selection, and this application will provide an opportunity to inform the management of hatchery and aquaculture programs.

frequency and magnitude of temperature extremes increase with
climate change, mass coral bleaching (potentially fatal loss of
symbiotic algae from the coral animal) events caused by thermal
stress threaten the persistence of coral reefs. However,
corals and their symbiotic algae may respond to climate change
through community shifts, physiological acclimation, and genetic
adaptation. Using theoretical models, my collaborators and I
explored the potential for coral response via rapid adaptation and
community shifts and compared indicators of corals‚€™ capacity to
survive climate change, including in the context of additional
anthropogenic impacts. These models further the
understanding of the interaction between evolutionary and
ecological processes, inform conservation management decisions,
and create a theoretical framework for synthesizing coral
bleaching data. (photo: reefbase.org)

Large-scale anthropogenic impacts such as fisheries on marine ecosystems has led to a rapid rise in interest in no-take marine protected areas. This project explored the implications of population and community-level life history variation for the effective design of marine reserve networks. In particular, this research investigated how reserve protection and fisheries impacts vary with growth, reproduction, and dispersal within and across populations, which has the potential to alter selection pressure and community structure. For this research, my collaborators and I constructed models that draw from a broad array of topics in theoretical ecology and inform fisheries and conservation management. (photo: fishbase.org)
