Research and Professional Interests:

Sponges are different from all other animals in the extreme simplicity and homogeneity of their construction. They are also one of the most diverse, abundant, and colorful groups in a variety of hard substratum marine systems, and many of their functional roles in these systems are not duplicated by members of other groups. I study the ecology of sponges and the organisms with which they interact as mutualistic partners, competitors, and prey, especially in coral reefs, seagrass meadows, and mangroves. I have been focusing on several conceptual issues that are especially intriguing for sponges: a) ecology and evolution of mutualisms; b) biogeographic and habitat patterns of diversity and abundance, and how these are influenced by interactions and life histories; and c) effects of physical disturbance and pathogens on population and community dynamics, focusing especially on the importance of different growth forms and life histories. My primary approaches to research are experimental manipulations in the field, combined with biogeographic comparisons; and most of my field work is in Belize, Panama, and the Florida Keys.
