About Gretchen Le Buhn

Interests: Plant evolutionary ecology, pollinator conservation and climate change.

My lab focuses on the effects of anthropogenic change on plant and animal communities from local to continental scales.We are currently working on the effect of wildfire on pollinator communities, the impacts of climate warming on urban pollinators  and the montane meadow pollinators.

I direct the Great Sunflower Project, a citizen science project, designed to evaluate the effects of landscape change on pollinator service in North America. 

I am also interested in the effects of variation in flower phenology on plant reproductive success. We use Linanthus dichotmous, a plant that flowers during the day north of San Francisco and at night south of San Francisco, as a model system.
