EEB Tuesday Lunch Seminar - "Applied Community Ecology: The Case of Puerto Rican Ants in Coffee"
with John Vandemeer, Asa Gray Distinguished University Professor of Ecology and Evolutionary Biology, Arthur F. Thurnau Professor
Coffee farms in Puerto Rico offer a perfect setting for studying community ecology since they are small, similar to one another and abundant, effectively creating a natural experiment. The ant community of these farms is evidently organized along the lines of what has come to be known as a metacommunity. The study of a particular assemblage of ants on one of these farms reveals interesting patterns of community structure, some of which relates directly to practical issues such as pest control and carbon sequestration. Specifically, the role of intransitive loops and higher order effects are evident and provide a mechanistic interpretation of some aspects of community structure.
