The majority of creatures are invertebrates. Invertebrate animals are the major energy conduits and agents of nutrient and material recycling in marine, freshwater, and terrestrial ecosystems throughout the world, and the sustainability of the earth's life-support systems depends on theirwell-being. Despite this, conservation managers and practitioners still know very little about invertebrate biology, or how to study and survey invertebrates adequately in the field. Invertebrate Surveys for Conservation is a comprehensive guide to the ecological methods used to surveyinvertebrate animals in terrestrial, freshwater, and marine environments. It describes how to select particular taxonomic groups for study, how to collect and analyse samples, and how to set priorities for protection in the face of limited resources. Line drawings of apparatus, tables of surveyexamples and methods of specimen treatment and sample analysis are augmented by a substantial list of references to provide and introduction to practical invertebrate conservation. This book will be an essential tool for anyone involved in conservation biology or ecology, including students andresearchers, conservation practitioners, and environmental consultants.

This account explores how to promote biodiversity without compromising agricultural production in highly managed agricultural ecosystems.

This is an updated version of the best selling first edition, Ecological Census Techniques, with updating, some new chapters and authors. Almost all ecological and conservation work involves carrying out a census or survey. This practically focussed book describes how to plan a census, the practical details and shows with worked examples how to analyse the results. The first three chapters describe planning, sampling and the basic theory necessary for carrying out a census. In the subsequent chapters international experts describe the appropriate methods for counting plants, insects, fish, amphibians, reptiles, mammals and birds. As many censuses also relate the results to environmental variability, there is a chapter explaining the main methods. Finally, there is a list of the most common mistakes encountered when carrying out a census.

Invertebrate Conservation and Agricultural Ecosystems explores the diverse interests of invertebrate conservation and agricultural production. It is both an introduction to invertebrate conservation biology for agriculturists and an introduction to crop protection for conservation biologists, demonstrating how these two disparate fields may draw on each other for greater collective benefit. It draws on recent literature to show how invertebrate conservation in highly altered landscapes may be promoted and enhanced. The book deals with problems of, and approaches to, invertebrate conservation in highly managed agricultural ecosystems, and how biodiversity may be promoted without compromising agricultural production. It draws attention to the importance of invertebrates in agricultural systems and their role in ecosystem functions.
