Biology, Evolution, and Conservation of Wild Bees

We use phylogenomics to reconstruct evolutionary relationships, collections-based research and community science to document bee diversity and promote bee conservation, metagenomics to understand bee-microbe interactions, and field surveys to document the role that wild bees play in crop pollination.

Areas of Interest

Phylogenomics

We are actively researching bee and wasp phylogenetic relationships through the use of high throughput DNA sequencing.

 

Diversity & Conservation

We are utilizing the power of community science to locate, characterize, and protect the valuable nesting sites of ground-nesting bees using the iNaturalist platform. For more information on this project, see Project GNBee.

Bee-microbe Interactions

We are exploring the diversity of microbes associated with solitary bee brood cells through high-throughput DNA sequencing.

Pollination Biology

We are documenting the important role of wild, native bees in agricultural pollination.

The Bee Course 2026

August 16-26, 2026

The Bee Course is a nine day intensive workshop offered for conservation biologists, pollination ecologists, and other biologists who want to gain greater knowledge of the systematics and biology of bees. Details of the course are provided on the Bee Course website.

Project GNBee

Conservation via Community Science

With initial funding from the Cornell Atkinson Center for Sustainability, we have established a community science program to identify, map, characterize, and conserve the valuable nesting sites of ground-nesting solitary bees (Project GNBee). Through engagement with a network of community scientists via our iNaturalist platform, we are learning where ground-nesting bee aggregations occur, developing predictive models to locate additional nestsites, creating a valuable research tool for melittologists (bee biologists), and conserving and protecting these valuable sites from human impact.
