    Research Overview

  • The basic science component of my research program concerns the ecological role of secondary metabolites in tropical reef invertebrates, particularly sponges. We are funded by NSF to investigate the allelopathic role of sponge compounds in coral overgrowth and inter-specific trade-offs between the production of chemical defenses and sponge growth, healing, and reproduction. The applied science component concerns the demography and bleaching of giant barrel sponges, which are major components of Florida’s coral reefs. We have been funded by NOAA to continue a 10-year sponge monitoring program on reefs off Key Largo, Florida, and to investigate possible environmental factors that may be involved with sponge bleaching. I have ongoing collaborations with Chris Finelli on barrel sponge pumping rates as it relates to sponge demographics and with Carm Tomas, via grad student Mike Echevarria, on the effects of HAB algae on suspension feeding invertebrates.
