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 their well-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 survey invertebrate 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 survey examples 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 and researchers, conservation practitioners, and environmental consultants.
