Marine Bivalves of Tropical West Africa


Book Description

Bivalves are one of the most important groups of marine animals: they are abundant in benthic communities, they are sought after as seafood or ornament, and their shells are almost always conspicuous on the world's beaches. This identification guide for West African marine bivalves covers 462 species belonging to 59 families, based on an extensive material collected over several decades from Mauritania (Cap Blanc) to Angola (Baia dos Tigres), and now housed in in the French National Museum of Natural History. Therefore, any bivalve collected in the marine near-shore habitats of West Africa is most likely to be covered. Deep sea species (those normally collected below 500 meters depth, an additional 150 species) are listed but not treated at length. Profusely illustrated with over 3500 color and 1600 greyscale photographs, 800 stippled drawings, and an average of twelve views per species, the book is intended to be both the definitive resource and accessible to the non-specialist. Each species receives a description accompanied by a drawing of the interior showing the diagnostic details of the hinge and internal impressions and a photographic plate showing a selection of specimens from different localities across the species' range, an indication of distribution accompanied by a schematic map, an indication of habitat, and remarks, including comparisons with similar species. In the headings for each family, generic descriptions are illustrated with thumbnails of the included species to provide visual orientation. Morphological terms used in descriptions are explained in a glossary. Preceding these extensive taxonomic sections of the book is an introduction addressing the history of research, the physiography and hydrology of West African coasts, and the general characteristics of bivalves.










Marine Bivalve Molluscs


Book Description

Marine Bivalve Molluscs Marine Bivalve Molluscs is a comprehensive and thoroughly updated Second Edition of Bivalve Molluscs, covering all major aspects of this important class of invertebrates. As well as being an important class biologically and ecologically, many of the bivalves are fished and cultured commercially (e.g. mussels, oysters, scallops and clams) in a multi-billion dollar worldwide industry. Elizabeth Gosling has written a landmark book that will stand for many years as the standard work on the subject. Chapters in Marine Bivalve Molluscs cover morphology, ecology, feeding, reproduction, settlement and recruitment, growth, physiology, fisheries, aquaculture, genetics, diseases and parasites, and public health issues. A full understanding of many of these aspects is vital for all those working in bivalve fisheries and culture. An essential purchase for anyone concerned with this important class of animals, copies of Marine Bivalve Molluscs should be on the shelves of biologists, ecologists, environmental scientists, fisheries scientists and personnel within the aquaculture industry. Copies of the book should be available in all libraries and research establishments where these subjects are studied or taught. REVIEWS OF THE FIRST EDITION An admirable achievement...a valuable addition to marine sciences libraries everywhere. The back cover of this book says that it is a landmark text that will stand for many years as the standard work on this subject. I can only agree with this sentiment. ~ Aquaculture A welcome addition to the literature and provides the reader with a comprehensive overview of biological and environmental factors that affect and control both natural populations of marine bivalves and culture operations. ~ Aquaculture International The author has done an admirable job in compiling a wealth of information into a readable text. ~ Transactions of the American Fisheries Society Will serve well as a description of much of both the experimental biology and the aquaculture of bivalves. ~ Journal of Experimental Marine Biology and Ecology Provides excellent reviews of all major aspects...an extremely important reference for anyone engaged in bivalve research, fisheries management, and aquaculture. ~ Quarterly Review of Biology The book is very readable, in an easy style. It is well illustrated and there is a wealth of data and statistics presented. ~ Bulletin of the Malacological Society of London




The Superfamily Mactroidea (Mollusca:Bivalvia) in American Waters


Book Description

This book identifies all valid species belonging to the superfamily Mactroidea living in American waters, distributed across fourteen biogeographical provinces. It also provides an updated classification of the widely occurring Mactroidea superfamily, which comprises eight subfamilies grouped into four families: Mactridae (Lamarck, 1809); Anatinellidae (Deshayes, J.Gray 1853); Cardiliidae (Fischer, 1887) and Mesodesmatidae (J. Gray, 1840). The species included in this superfamily are known to have existed in North America since the Early Cretaceous.




Faune des poissons d'eaux douces et saumâtres de l'Afrique de l'Ouest


Book Description

This new reexamined and corrected fauna displays an up to date account of knowledge on the systematics of the fresh and brackish water fishes of West Africa. Its aim is to help ichthyologists with the identification of the species they collect. It is made practical and didactic by paying special attention to iconography and as far as possibly by giving priority to the simplest and easiest observable criteria. West Africa, from the Senegal River basin in the North West to the Chad basin in the North East and the Cross River in the South, includes the majority of the Sahelo-Sudan basins, except for the Nile, and the Western Guinea area, covering the Atlantic Coastal Basins from Guinea to Western Cote d'Ivoire. Specialists of each group or family were called to write the chapters. To facilitate the access of this fauna, an English translation is provided for all text. Summary tables, comparing morphological characters and measures for the different species, complement the identification keys. Distribution maps are provided for freshwater species. At present, 64 families are described, including 192 genera and 584 valid species. A reduced paper version is presented in two volumes; the integral CD-ROM version is inserted on the back cover of the second volume.







Nature


Book Description

From humans to hermit crabs to deep water plankton, all living things compete for locally limiting resources. This universal truth unites three bodies of thought--economics, evolution, and history--that have developed largely in mutual isolation. Here, Geerat Vermeij undertakes a groundbreaking and provocative exploration of the facts and theories of biology, economics, and geology to show how processes common to all economic systems--competition, cooperation, adaptation, and feedback--govern evolution as surely as they do the human economy, and how historical patterns in both human and nonhuman evolution follow from this principle. Using a wealth of examples of evolutionary innovations, Vermeij argues that evolution and economics are one. Powerful consumers and producers exercise disproportionate controls on the characteristics, activities, and distribution of all life forms. Competition-driven demand by consumers, when coupled with supply-side conditions permitting economic growth, leads to adaptation and escalation among organisms. Although disruptions in production halt or reverse these processes temporarily, they amplify escalation in the long run to produce trends in all economic systems toward greater power, higher production rates, and a wider reach for economic systems and their strongest members. Despite our unprecedented power to shape our surroundings, we humans are subject to all the economic principles and historical trends that emerged at life's origin more than 3 billion years ago. Engagingly written, brilliantly argued, and sweeping in scope, Nature: An Economic History shows that the human institutions most likely to preserve opportunity and adaptability are, after all, built like successful living things.




Biogeography and Biodiversity of Western Atlantic Mollusks


Book Description

Shallow water marine molluscan faunas are distributed in a pattern of distinct, geographically definable areas. This makes mollusks ideal for studying the distribution of organisms in the marine environment and the processes and patterns that control their evolution. Biogeography and Biodiversity of Western Atlantic Mollusks is the first book to us
