Understanding how environmental stressors shape plant-pollinator and pollinatorpathogen interactions and dynamics in anthropogenic landscapes, and the consequences for pollinator health, plant reproduction, and ecosystem services. Please see the Fitch Lab website for more detail.

Research Focus

Research in the lab focuses on how environmental stressors affect species interactions and the consequences for populations and ecosystem function. Because they are super cool and also super important, we mostly focus on pollinator-plant, and especially bee-plant, interactions. Current projects in the lab focus on the effects of urbanization and agricultural land management on bee movement and foraging, the role of parasites in shaping bee foraging preferences, and the effects of the built environment on bee-parasite interactions.

We use a variety of techniques to address these questions, including field surveys, manipulative experiments in both the lab and the field, and multiple modeling approaches. Our work is motivated by the desire to better understand ecological complexity and the imperative to conserve biodiversity and promote just, sustainable futures.
