Using intraspecific trait variation to understand processes structuring continental-scale biodiversity patterns.
Understanding variation in the internal and external drivers of community composition across taxa and systems informs both ecological theory and conservation, particularly regarding the resilience and composition of ecological communities in the face of rapid global change. For this project, my collaborators and I use National Ecological Observatory Network (NEON) data on intraspecific trait variation, collect additional measurements from NEON organismal samples, and compile additional data related to NEON sites and samples (e.g., phylogenetic community structure) to determine how assembly processes internal to the community (e.g., biotic interactions, microenvironmental heterogeneity) and large-scale assembly processes external to the community (e.g., climate, land use) combine to affect intraspecific trait variation and community structure at a continental scale. I collaborate with Phoebe Zarnetske (Michigan State University), Angela Strecker (Portland State University, Sydne Record (Bryn Mawr College), Lydia Beaudrot (University of Michigan), Yoni Belmaker (Tel Aviv University), and Mao-Ning Tuanmu (Yale) on this project which is funded by the National Science Foundation- Division of Environmental Biology.
Intraspecific body mass within small mammal communities shows decreasing overlap at higher temperatures across NEON sites.
