Ecology and evolution of species range limits
We study plants, often monkeyflowers (Mimulus species) among other plant groups, to understand (1) niche evolution and the underpinnings of distributions, (2) adaptations, tolerances, and evolutionary potentials to adapt to varying environments and (3) consequences of historical and experimental gene flow on these processes. We examine the role of selection, gene flow, and range limits in determining plant adaptations. For example, we study Mimulus laciniatus across its species range. Populations across a broad elevation gradient are being examined in common gardens representing the climate breadth of the species range, and beyond. Population genetics/genomics are being used to understand adaptive responses in the context of gene flow. Continuing research includes climate-based and local-scale niche evolution and niche convergence among closely related species and their genomic basis.
Adaptation in novel environments
We are investigating mountain plants in the California Sierra Nevada and Australian Alps and focusing on species range size and the role of gene flow on the processes of adaptation and tolerance to rapidly changing environments. The performance of mountain plants are being tested under a variety of conditions representing different types of environmental stress. Comparative studies include a variety of plant groups, including native grasses, sedges, and forbs.
Global change and sustainability science
We are fascinated, and motivated, by the question of how to manage ecosystems sustainably in the face of global change, and enjoy collaborating across traditional research fields.
