Tropical Ecology and Conservation

Amy Dunham


Welcome to our lab at Rice University!

Department of Biosciences, Program in Ecology and Evolutionary Biology


We are a group of ecologists interested in tropical ecology and conservation biology. Our work focuses on evolutionary, population, and community ecology and is often applied to conservation issues in tropical rainforests.


Our research is conducted in Texas, West and Central Africa, the Mariana Islands, and Madagascar
