The Crustacea is one of the dominant invertebrate groups, displaying a staggering diversity in form and function, and spanning the full spectrum of Earth's environments. Crustaceans are increasingly used as model organisms in all fields of biology, as few other taxa exhibit such a variety of body shapes and adaptations to particular habitats and environmental conditions. In the tenth and final volume of "The Natural History of the Crustacea" series, Ecology and Conservation emphasizes that understanding the ecological roles of crustaceans is fundamental to achieve their conservation in aquatic and terrestrial ecosystems. Written by internationally recognized experts studying a wide range of crustacean taxa and topics, this volume synthesizes current research in a format that is accessible to a wide scientific audience.
