Tropical Ecology and Conservation

Amy Dunham 

Welcome to our lab!

……………………………………………………………………………………………………………...

 

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

 

Our research is conducted in Texas, West and Central Africa, Madagascar, and Brazil.
