Welcome to the Bagley lab website! The lab was established in Autumn 2020 at OSU Lima. We are an evolutionary biology lab that seeks to understand how biodiversity is generated and maintained in natural populations. Specifically, we are interested in the drivers of diversity in herbivorous insects, and if and how differentiation at the plant-insect trophic level radiates through, and in turn is impacted by, interactions with other trophic levels (parasites, diseases, etc.). We take an integrative approach to answer these questions, evaluating genotypic and phenotypic data in the context of both natural history information and environmental variation. We hope you will join us as we continue to explore these questions in our focal system: the community of insects associated with Neodiprion sawflies.
