Work in the chemical ecology and tropical diversity laboratory focuses on direct and indirect trophic interactions in complex biotic communities with emphases on global change, documenting the diversity of multi-trophic interactions, and examining the effects of plant secondary compounds on insect herbivores and their natural enemies. The main source of funding for our research comes from the National Science Foundation, Earthwatch Institute, the Department of Defense, and private funding sources. The major continuing research topics of our laboratory and collaborators include: 1) Chemical ecology; 2) Diversity of interactions in tropical and temperate forests; 3) Variation in tritrophic interactions due to climate change; 4) Conservation and applied ecology; 5) Quantitative ecology; 6)Coevolution across multiple trophic levels
