Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2013-04-08 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The peanut-shaped sternaspid polychaetes have been known since 1760 when Plancus named them as Mentula cucurbitacea marina. Sternaspids are common and abundant in soft bottoms. Some authors suggested that only one species should be recognized, whereas others regard a few species very widely distributed and variable depths. Delineating species was problematic; the ventro-caudal shield was disregarded or barely used for identifying species. In this contribution the ventral shield is evaluated and its diagnostic potential is confirmed. The revision of Sternaspis is based upon type or topotype materials. Sternaspid body, introvert hooks and shield show three distinct patterns: two genera have 7 abdominal segments and tapered introvert hooks, and one genus has 8 abdominal segments and spatulate introvert hooks. The ventro-caudal shield has 3 different patterns: stiff with ribs, and sometimes concentric lines, stiff with feebly-defined ribs but no concentric lines, and soft with firmly adhered sediment particles. Sternaspis is restricted to include species with 7 abdominal segments, falcate introvert hooks, and stiff shields, often exhibiting radial ribs, concentric lines or both. Two new genera incorporate the remaining species: Caulleryaspis has falcate introvert hooks, 7 abdominal segments, and soft shields with sediment particles firmly adhered on them. Petersenaspis has spatulate introvert hooks, 8 abdominal segments, and stiff shields with poorly-defined ribs but no concentric line. The geographic range of most species is smaller than previously indicated. Keys to genera and to all species are also included.
