Research Interests
Craig Dahlgren, a marine ecologist, is primarily interested in studying populations of important fishery species in the Caribbean and the community ecology of coral reef and lagoonal habitats of the Caribbean. Specifically, much of his research focuses on factors that influence populations of Nassau grouper, Caribbean spiny lobster, and other important fishery species, particularly their recruitment, and use of various coral reef and off-reef nursery habitats. He is interested in the design and effects of marine protected areas, especially no-take marine reserves, and how protected areas can be used to sustain fisheries and protect ecosystem function. Craig has been conducting research in The Bahamas and elsewhere in the Caribbean for over a decade.
