Download or read book Faune des poissons d eaux douces et saum tres de l Afrique de l Ouest written by Didier Paugy and published by IRD Orstom. This book was released on 2003 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Sea Level Rise for the Coasts of California Oregon and Washington written by National Research Council and published by National Academies Press. This book was released on 2012-12-06 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tide gauges show that global sea level has risen about 7 inches during the 20th century, and recent satellite data show that the rate of sea-level rise is accelerating. As Earth warms, sea levels are rising mainly because ocean water expands as it warms; and water from melting glaciers and ice sheets is flowing into the ocean. Sea-level rise poses enormous risks to the valuable infrastructure, development, and wetlands that line much of the 1,600 mile shoreline of California, Oregon, and Washington. As those states seek to incorporate projections of sea-level rise into coastal planning, they asked the National Research Council to make independent projections of sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account regional factors that affect sea level. Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future explains that sea level along the U.S. west coast is affected by a number of factors. These include: climate patterns such as the El Niño, effects from the melting of modern and ancient ice sheets, and geologic processes, such as plate tectonics. Regional projections for California, Oregon, and Washington show a sharp distinction at Cape Mendocino in northern California. South of that point, sea-level rise is expected to be very close to global projections. However, projections are lower north of Cape Mendocino because the land is being pushed upward as the ocean plate moves under the continental plate along the Cascadia Subduction Zone. However, an earthquake magnitude 8 or larger, which occurs in the region every few hundred to 1,000 years, would cause the land to drop and sea level to suddenly rise.
Download or read book Suisun Marsh written by Peter B. Moyle and published by Univ of California Press. This book was released on 2014-03-26 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of California's most remarkable wetlands, Suisun Marsh is the largest tidal marsh on the West Coast and a major feature of the San Francisco Estuary. This productive and unique habitat supports endemic species, is a nursery for native fishes, and is a vital link for migratory waterfowl. The 6,000-year-old marsh has been affected by human activity, and humans will continue to have significant impacts on the marsh as the sea level rises and cultural values shift in the century ahead. This study includes in-depth information about the ecological and human history of Suisun Marsh, its abiotic and biotic characteristics, agents of ecological change, and alternative futures facing this ecosystem.

Available in PDF, EPUB and Kindle. Book excerpt: This field guide covers the major resource groups likely to be encountered in the fisheries of the Cambodian Mekong. These groups include sharks, batoid fishes and bony fishes. The introduction outlines the geographical, environmental and ecological factors influencing fisheries, and the basic components of the fisheries of the Cambodian Mekong. As an aid to identification to higher taxonomic levels, a pictorial index to families and an illustrated guide to orders and families are included. Each species account provides scientific nomenclature, FAO names in English, local names, sizes, notes on fisheries, habitat and biology, and one or more illustrations. The guide is fully indexed and a list of related literature is appended. Finally, 27 colour plates are presented.

Download or read book The Geomorphology of Rock Coasts written by Alan S. Trenhaile and published by Oxford University Press, USA. This book was released on 1987 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the only comprehensive reference work in the English language to deal specifically with landforms and processes of rock coasts. The workings of mechanical wave action, chemical weathering, bio-erosion, frost, and mass movement are among the topics covered in the first section. The second half discusses the landforms resulting from these processes, such as cliffs, bays and headlands, and elevated marine terraces. The material is clearly expressed and up-to-date, with examples taken from a wide range of environments. It is highly relevant reading for geomorphologists in physical geography departments, as well as for engineers, biologists, and geologists working in coastal areas.
Download or read book Cyprinid Fishes written by Ian J. Winfield and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 687 pages. Available in PDF, EPUB and Kindle. Book excerpt: Among the fishes. a remarkably wide range ofbiological adaptations to diverse habitats has evolved. As weIl as living in the conventional habitats of lakes. ponds. rivers. rock pools and the open sea. fish have solved the problems of life in deserts. in the deep sea. in the cold Antarctic. and in warm waters of high alkalinity or of low oxygen. Along with these adaptations. we find the most impressive specializations of morphology. physiology and behaviour. For example we can marvel at the high-speed swimming of the marlins. sailfish and warm-blooded tunas. air breathing in catfish and lungfish. parental care in the mouth-brooding cichlids and viviparity in many sharks and toothcarps. Moreover. fish are of considerable importance of the survival of the human species in the form ofnutritious and delicious food ofnumerous kinds. Rational exploitation and management of our global stocks of fishes must rely upon a detailed and precise insight of their biology. The Chapman and Hall Fish and Fisheries Series aims to present timely volumes reviewing important aspects of fish biology. Most volumes will be of interest to research workers in biology. zoology. ecology and physiology. but an additional aim is for the books to be accessible to a wide spectrum of non specialist readers ranging from undergraduates and postgraduates to those with an interest in industrial and commercial aspects of fish and fisheries.
Download or read book Ecology Conservation and Restoration of Tidal Marshes written by Arnas Palaima and published by Univ of California Press. This book was released on 2012-09-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Francisco Bay, the biggest estuary on the west coast of North America, was once surrounded by an almost unbroken chain of tidal wetlands, a fecund sieve of ecosystems connecting the land and the Bay. Today, most of these wetlands have disappeared under the demands of coastal development, and those that remain cling precariously to a drastically altered coastline. This volume is a collaborative effort of nearly 40 scholars in which the wealth of scientific knowledge available on tidal wetlands of the San Francisco Estuary is summarized and integrated. This book addresses issues of taxonomy, geomorphology, toxicology, the impact of climate change, ecosystem services, public policy, and conservation, and it is an essential resource for ecologists, environmental scientists, coastal policymakers, and researchers interested in estuaries and conserving and restoring coastal wetlands around the world.
Download or read book Fish and Fisheries at Higher Altitudes written by T. Petr and published by Food & Agriculture Org.. This book was released on 1999 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thirteen papers presented in this publication review fish stocks and fisheries of mountainous areas of Asia: Himalayas (Bhutan, Nepal, northern states of India within the Himalayas), Western Ghats (India), Karakoram-Hindu Kush (Pakistan, Afghanistan), Pamir (Tajikistan), Tien Shan (Kyrgyzstan, Kazakhstan), Altai (Kazakhstan, Mongolia, China), high altitude lakes of Mongolia and those of western China (provinces of Qinghai and Xinjiang [Uighur Autonomous Region] and Xizang [Tibet Autonomous Region]) and Caucasus (Armenia, Georgia, Azerbaijan). From south to north, fish fauna complexes change from Oriental to Palaearctic. Cool and coldwater streams and rivers support subsistence and/or recreational/sport fisheries, with commercial fisheries practised only in some lakes and reservoirs. While fishing of streams and rivers is largely unmanaged, considerable management effort has gone into some lakes and reservoirs, especially in Kazakhstan, Kyrgyzstan and India in order to maintain reasonably high fish catches. The management measures have included translocation and stocking of exotic fish species and regulation of fisheries. For recreational fishery, brown trout has been stocked in rivers and streams of the southern slopes of Himalayas, rainbow trout in some streams of Western Ghats ... etc.
