Abstract
I propose to develop a multi-species, spatially structured framework for looking at problems in conservation. I have three goals: (1) Integrate theory on species interactions
and spatial structure to develop general rules of thumb, (2) Explore databas es, particularly on island biota, to determine whether the rules suggested by theory reflect important differences among natural species interactions in spatially structured environments, and (3) Develop PVA type models to determine when species interact ions and spatial structure are important in management considerations such as reserve design.
