     The purpose of this study was to gather basic ecological data on white-fronted brown lemurs (Eulemur fulvus albifrons) in an area of Eastern lowland rainforest in Madagascar. Behavioral and dietary data were collected using scan sampling on one focal group of white-fronted brown lemurs from April – July 2005 in Betampona Natural Reserve, Madagascar. Data were collected on several other groups opportunistically. E. f. albifrons were found in groups ranging from 1-22 individuals, generally in polygynandrous groups. Groups were cohesive except during a brief migration period in April, in which individuals split up and traveled 1-2 kilometers from primary forest to secondary forest. We observed our focal group resting for most observations (67%), followed by travel (15%) and feeding (12%). Thirty-eight plant species were eaten by E. f. albifrons during the four month study period, and preliminary data show that ripe fruits made up 46% of the overall diet, followed by nectar (40%). Due to the proportion of nectar consumed during the study, our data suggest that E. f. albifrons acts as a potential pollinator of the traveler’s palm, Ravenala madagascariensis in Betampona.
