Available in PDF, EPUB and Kindle. Book excerpt: Jellyfish are one of the most conspicuous animals in our oceans and are renowned for their propensity to form spectacular blooms. The unique features of the biology and ecology of jellyfish that enable them to bloom also make them successful invasive species and, in a few places around the world, jellyfish have become problematic. As man increasingly populates the world’s coastlines, interactions between humans and jellyfish are rising, often to the detriment of coastal-based industries such as tourism, fishing and power generation. However we must not lose sight of the fact that jellyfish have been forming blooms in the oceans for at least 500 million years, and are an essential component of normal, healthy ocean ecosystems. Here many of the world’s leading jellyfish experts explore the science behind jellyfish blooms. We examine the unique features of jellyfish biology and ecology that cause populations to ‘bloom and bust’, and, using case studies, we show why jellyfish are important to coastal and ocean ecosystem function. We outline strategies coastal managers can use to mitigate the effects of blooms on coastal industries thereby enabling humans to coexist with these fascinating creatures. Finally we highlight how jellyfish benefit society; providing us with food and one of the most biomedically-important compounds discovered in the 20th century.

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.

This second edition discusses major new developments, including phase shifts in many coastal and estuarine ecosystems dominated by suspension-feeding bivalves, the invasion or introduction of alien bivalve species, the rapid growth of environmental restoration focused on bivalves, and the examination of geological history with regard to global climate change and its impact on bivalve-dominated systems.
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 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.

This book was released on 2001 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jellyfish', a group that includes scyphomedusae, hydromedusae, siphonophores and ctenophores, are important zooplankton predatorsthroughout the world's estuaries and oceans. These beautiful creatureshave come to public attention as featured exhibits in aquaria and innews headlines as invaders and as providers of genes used inbiomedical research. Nevertheless, jellyfish are generally consideredto be nuisances because they interfere with human activities bystinging swimmers, clogging power plant intakes and nets of fishermenand fish farms, and competing with fish and eating fish eggs andlarvae. There is concern that environmental changes such as globalwarming, eutrophication, and over-fishing may result in increasedjellyfish populations.The literature reviews and research papers in this volume explore theinteractions between jellyfish and humans. Papers cover the medicalaspects of jellyfish stings, jellyfish as human food and jellyfishfisheries, interactions of jellyfish and fish, effects ofenvironmental changes on jellyfish, effects of introduced ctenophoreson the Black Sea ecosystem, factors causing increases orconcentrations of jellyfish, and others aspects of jellyfish ecology.This is an important reference for students and professional marinebiologists, oceanographers, fishery scientists, and aquarists.

Download or read book Sensitivity of Mangrove Ecosystem to Changing Climate written by Abhijit Mitra and published by Springer Science & Business Media. This book was released on 2013-08-13 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mangroves are basically salt tolerant forest ecosystems found mainly in tropical and sub-tropical inter-tidal regions. Till about 1960s, mangroves were largely viewed as “economically unproductive areas” and were therefore destroyed for reclaiming land for various economic and commercial activities. Gradually, with the passage of time, the economic and ecological benefits of mangroves have become visible and their importance is now well appreciated. Today, mangroves are observed in about 30 countries in tropical subtropical regions covering an area of about 99,300 Sq.Km. However, during the past 50 years, over 50% of the mangrove cover has been lost, mainly because of the increased pressure of human activities like shrimp farming and agriculture, forestry, salt extraction, urban development, tourist development and infrastructure. Also, dam on rivers, contamination of sea waters caused by heavy metals, oil spills, pesticides and other products etc. have been found to be responsible for the decline of mangroves. Although the temperature effect on growth and species diversity is not known, sea-level rise may pose a serious threat to these ecosystems The present book addresses all these important issues in separate chapters with some interesting case studies whose data may serve as pathfinder for future researches in the sphere of the influence of climate change on mangrove ecosystem. The role of mangroves in the sector of bioremediation is a unique feather in the crown of this coastal and brackishwater vegetation that may be taken up by the coastal industries in order to maintain the health of ambient environment. This book seeks to discover and to assess the vulnerability of climate change on mangrove flora and fauna, their role in carbon sequestration and some interesting case studies by some groups of dedicated researchers that may serve as the basis of future climate related policies.

This book was released on 2016-02-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tropical Deep-Sea Benthos is a series dedicated to the inventory and description of the deep-sea fauna of the world, with special emphasis on their most extensive--but remote and least-explored--habitats: the Indo-West Pacific. Growing out of marine expeditions undertaken by the French National Museum of Natural History and the Institut de Recherche pour le Développement, the series continues to present many new, strange, and sometimes colorful invertebrates. The present volume presents results from recent expeditions within the New Caledonian Exclusive Economic Zone, reporting ninety-eight species (including fifty-seven new species) of corals from the Stylasteridae family and one new calcified species of hydrozoa from the family Hydractiniidae. Including numerous seamounts, submarine ridges, and small islands, New Caledonia's deep-sea benthos are ideal habitat for stylasterids, making it the most species-rich marine region in the world for this taxon.
