This volume is a republication in one volume of the 10 part "CIH Keys to the Nematode Parasites of Vertebrates," first published between 1974 and 1983. For many years the "Keys" have provided a working tool to those within the field and laboratory needing to know "what is this worm?" Now due to popular demand and to coincide with the long awaited publication of the supplement volume, the "Keys" will be presented as one volume, refreshed and reformatted with the additional convenience of reordering in to superfamily. As an indispensable guide the "Keys" shall continue to be an essential resource to those working within medical, veterinary and biological departments worldwide for many more years to come.

Many species of the phylum Nematoda, the nonsegmented worms, play an important role as animal or plant parasites; most species are active contributors to the decomposition cycle in soil ecosystems, but the details of that contribution are just beginning to be understood. Agricultural nematologists, vitally involved in the study of the methodology, taxonomy, and biology of the species due to the direct relationship between crop yield and the size of plant-parasitic nematode populations, have provided much information about the nematodes. More recently, ecologists have contributed additional data on the structure and function of the total soil community, including energy flow and nutrient cycling, and have examined the critical and multifaceted role of soil nematodes in such communities. Nematodes in Soil Ecosystems provides a valuable synthesis of significant research in this area and may stimulate further important communication between the agricultural and ecological branches of nematode research.

Most animals are invertebrates, yet conservation managers and practitioners know very little about their biology, or how to study and survey them adequately in the field. Invertebrate Surveys for Conservation is a comprehensive guide to the ecological methods used to survey invertebrate animals in terrestrial, freshwater, and marine environments. Containing practical advice and discussion on optimal sampling methods, and on how to interpret samples effectively for practical conservation assessment, this book will be an essential tool for anyone involved in conservation biology or ecology.

Whether through loss of habitat or cascading community effects, diseases can shape the very nature of the marine environment. Despite their significant impacts, studies of marine diseases have tended to lag behind their terrestrial equivalents, particularly with regards to their ecological effects. However, in recent decades global research focused on marine disease ecology has expanded at an accelerating rate. This is due in part to increases in disease emergence across many taxa, but can also be attributed to a broader realization that the parasites responsible for disease are themselves important members of marine communities. Understanding their ecological relationships with the environment and their hosts is critical to understanding, conserving, and managing natural and exploited populations, communities, and ecosystems. Courses on marine disease ecology are now starting to emerge and this first textbook in the field will be ideally placed to serve them. Marine Disease Ecology is suitable for graduate students and researchers in the fields of marine disease ecology, aquaculture, fisheries, veterinary science, evolution and conservation. It will also be of relevance and use to a broader interdisciplinary audience of government agencies, NGOs, and marine resource managers.

The marine zooplankton is one of the most fascinating and diverse assemblages of animals known to biologists. This student manual provides a photographic guide to representative forms of the major groups from medusae and comb jellies to larval fish and squid. In it, only photographs of live and active organisms appear, giving a unique visual perspective. In this new edition, the authors have revised and updated the taxonomy and morphology so that combined with information on behavior and development, this book creates a vivid and essential reference.
