Bee symbioses provide unique systems in which to investigate the interactions between mutualists and parasites in different environmental contexts. Native bees are associated with a number of important symbioses, two of which are their mutualistic relationship with flowering plants and their parasitic relationship with other insects and microbes. Individually, bees’ relationships with plants and parasites have been studied on multiple biological levels, but these interactions take place in complex environments where many factors may influence the relative effect that each relationship has on each organism. GEMS trainee Annaliese Wargin will focus on the relationships between bumblebees, flowering plants, and bee parasites in agriculturally situated pollinator habitat to determine how landscape may affect the different levels of these symbioses.
