Carolyn Kurle


Research in the Kurle lab focuses on understanding how animal foraging and trophic patterns drive community ecology. We use stable isotope biogeochemistry to answer questions regarding trophic interactions, niche partitioning, and habitat use, and our research informs conservation and management of species and ecosystems. We also seek to understand the best use of biogeochemical tools to address ecological problems. Our work takes place mostly in marine, coastal, and island systems.
