This important and extensive volume presents part of the Proceedings of the Fourth International Crustacean Congress held in Amsterdam in 1998. As the title implies, 'Crustaceans and the Biodiversity Crisis' was the general, underlying theme of all contributions at the congress. With the turn of the century, someone ought to 'assess the balance' of our natural environment and of the various branches of biology that study its rapidly declining diversity. From the five subthemes covered at the conference, those of (1) "Diversity in Time and Space" (including Systematics, Phylogeny, and Palaeontology), (2b) "Biogeography," (3c) "Larvae," and (4) "Physiology and Biochemistry" (including Molecular Biology and Genetics) are represented in this volume, along with a few contributions from other subthemes (e.g. (2a) "Invasive Crustacea," (3a) "Ecology," (3b) "Behaviour," and (5) "Fisheries and Aquaculture"). The book is primarily meant for scientists working at institutes involved in research on the group (Crustacea: marine, freshwater, or terrestrial) and/or the disciplines covered. Individual carcinologists working on one of the themes discussed in this volume, will find a wealth of interesting and timely contributions, as will other scientists working in marine or freshwater biology or in soil ecology.

The papers in this volume have been grouped according to the main sub-themes of the congress and primarily deal with the biodiversity issues of invasive crustacea, ecology and behaviour and fisheries and aquaculture.

This book introduces updated information on conservation issues, providing an overview of what is needed to advance the global conservation of freshwater decapods such as freshwater crabs, crayfish, and shrimps. Biodiversity loss in general is highest in organisms that depend on intact freshwater habitats, because freshwater ecosystems worldwide are suffering intense threats from multiple sources. Our understanding of the number and location of threatened species of decapods, and of the nature of their extinction threats has improved greatly in recent years, and has enabled the development of species conservation strategies. This volume focuses on saving threatened species from extinction, and emphasizes the importance of the successful implementation of conservation action plans through cooperation between scientists, conservationists, educators, funding agencies, policy makers, and conservation agencies.
