Show Summary Details


This chapter presents the basic macroecological features of the deep-sea fauna, including geographic variation in standing stock, species diversity, species ranges, and body size. It also explores the relationships among body size, diversity, and abundance, and between body size and metabolic rate. Whenever possible, the chapter compares these trends to those found in other ecosystems. It concentrates on the deep North Atlantic Ocean, which is by far the most intensively sampled region of the World Ocean. The emphasis is on communities that inhabit the soft-sediment habitats covering most of the seafloor. This chapter provides an excellent summary of biogeographic patterns in deep-sea chemosynthetic habitats. Many of the case studies in the chapter involve mollusks, because their taxonomy and biogeography are relatively well known, owing to the extensive published work of Philippe Bouchet, Anders Waren, John Allen, Howard Sanders, and their colleagues. While the data are limited and geographically restricted, they begin to provide a macroecological context for studying deep-sea assemblages.
