Symbiotic relationships are pervasive in nature, and the McFrederick lab aims to understand the evolution and ecology of these relationships. We focus on understanding how symbioses affect the viability of wild bee populations, with the ultimate goal of protecting these important pollinators. We ask basic scientific questions that are rooted in natural history and have implications for conservation: How are symbionts acquired? Are interactions between microbial guilds important for host health? How does host social structure influence symbiont evolution and symbiont community structure? To answer these questions, we use a combination of experimentation, phylogenetics and phylogenomics, population genetics and genomics, and bacterial community next-generation sequencing surveys.
