Molluscan Communities of the Florida Keys and Adjacent Areas: Their Ecology and Biodiversity is the first comprehensive overview of the ecology and biodiversity of the phylum Mollusca in the area of Florida extending from the Dry Tortugas and Ten Thousand Islands in the west to Palm Beach in the east. The book provides detailed analyses of molluscan faunas found in 20 different ecosystems, emphasizing the marine environments of the Florida Keys archipelago and its extensive coral reef tracts. Full-page color illustrations portray living animals, unique Keys environments, underwater ecosystems, and satellite images. More than 1,200 species of macromollusks—in 86 gastropod families and 54 bivalve families—are recorded from the study area, with color plates illustrating over 550 of the region’s most ecologically important species. For the first time in any book on the malacology of the Florida Keys area, the 20 marine ecosystems and their associated molluscan assemblages are arranged by the CMECS (Coastal Marine Ecological Classification Standard) system. This system emphasizes the hierarchical relationships determined by substrate type, bathymetry, and water chemistry. Along with complete species lists for every molluscan assemblage, this handy guide introduces ten newly-discovered gastropods, including new species in the families Muricidae, Buccinidae, Nassariidae, Naticidae, Turritellidae, and Olividae. Two new bivalves in the families Pectinidae and Arcidae are also described in a special systematic appendix. This richly illustrated book is written for the professional scientific audience interested in mollusks, marine ecology, evolution, and taxonomy as well as malacologists, naturalists, and shell collectors. It is also an ideal synoptic field guide, showing where individual species of mollusks can be found and within which ecosystems they occur.
