Biography
The longitudinal research objective that my students and I pursue is to integrate evolutionary ecology and conservation biogeography to model primate responses to anthropogenic disturbances. The specific aim of our research program is to determine how forest loss, forest fragmentation, and forest edges influence lemur ecology in Madagascar. Most of our research takes place in tropical dry forests in and around Ankarafantsika National Park, in NW Madagascar.
