Onja awarded IFS and Rufford Foundation research grants !
Onja Razafindratsima was awarded grants from the International Foundation for Science and Rufford Foundation for her research in Madagascars southeastern rainforests.
Two recent articles from the dunham group make journal cover
Emily Wheeler wins best EEB poster at RURS!
She explored the predictive value of phylogeny and traits for extinction and endangerment risk in Madagascar's lemurs
Rogers (PI), Dunham, and Miller (UGuam) receive NSF grant
Grant is to study effects of disperser loss on forest gap-dynamics. Visit the Ecology of Bird Loss webpage to learn more
Onja Razafindratsima named Schlumberger Faculty for the Future Scholar (again)
In addition to this prestigious fellowship, Onja also received the Garden Club of America Award in Tropical Botany and a Rufford Grant to support her research in Madagascar and the Davidson-Christoph award from OTS to attend the 2013 ATBC meeting.
Welcome to our lab at Rice University!
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 West and Central Africa, the Mariana Islands, Madagascar and Peru.
