Population ecology, predator-prey interactions, wetland ecology, and the biology of pollinators
My lab has started to do research on various aspects of honeybee biology and while we are in the very early stages of this program, a lot of avenues have opened up for students doing research. For one, a partnership with the local restaurant, Founding Farmers, led to a stipend and a significant increase in the number of bee hives we can maintain at GW.
Students in the bee lab are currently working on answering several questions:
- Do urban honeybee hives are healthier overall compared to hives kept in rural areas?
- What are the differences in pollination patterns in urban vs. rural environments?
- Do bees feeding on better, healthier pollen and nectar fight parasites and pathogens with greater success?
- How does the bee venom composition vary with pollen quality?
We plan to expand our research efforts in the near future to also include studies on the community ecology of native pollinators in urban environments.
