Main Focus

I am a behavioral ecologist, interested in the ecology and evolution of social behavior. I study the social strategies animals use to overcome challenges imposed by unpredictable environments, in the wild. In particular, I investigate benefits and costs of social information use and communication in the foraging context, and the relationship between resource distribution and social foraging strategy. I address my research questions with bats because of their impressive ecological and social diversity and energetically demanding lifestyle which places strong selective pressure on adaptive social strategies.

In my Masters I investigated the potential for social information encoded in echolocation calls to facilitate the social foraging strategy of the ephemeral insect swarm specialist, Molossus molossus. Currently for my PhD, I am investigating the social foraging strategies of two more neotropical bat species that also specialize on ephemeral prey, Noctilio albiventris and Noctilio leporinus. I use miniaturized biologging technologies to record foraging movements and vocalizations for whole colonies of these bats and additional field methods to map the dynamic prey landscapes they experience. Using these data I investigate foraging movements in relation to group members and prey distribution to test hypotheses about how distribution of food resources in space and time and qualities of social information drive social foraging strategies.
