Download or read book Coastal Wetlands written by Gerardo M.E. Perillo and published by Elsevier. This book was released on 2009-01-18 with total page 975 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal wetlands are under a great deal of pressure from the dual forces of rising sea level and the intervention of human populations both along the estuary and in the river catchment. Direct impacts include the destruction or degradation of wetlands from land reclamation and infrastructures. Indirect impacts derive from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. As sea level rises, coastal wetlands in most areas of the world migrate landward to occupy former uplands. The competition of these lands from human development is intensifying, making the landward migration impossible in many cases. This book provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide, and suggestions for their management. In this book a CD is included containing color figures of wetlands and estuaries in different parts of the world. - Includes a CD containing color figures of wetlands and estuaries in different parts of the world.
Download or read book Salt Marshes written by Judith S Weis and published by Rutgers University Press. This book was released on 2009-07-16 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tall green grass. Subtle melodies of songbirds. Sharp whines of muskrats. Rustles of water running through the grasses. And at low tide, a pungent reminder of the treasures hidden beneath the surface.All are vital signs of the great salt marshes' natural resources. Now championed as critical habitats for plants, animals, and people because of the environmental service and protection they provide, these ecological wonders were once considered unproductive wastelands, home solely to mosquitoes and toxic waste, and mistreated for centuries by the human population. Exploring the fascinating biodiversity of these boggy wetlands, Salt Marshes offers readers a wealth of essential information about a variety of plants, fish, and animals, the importance of these habitats, consequences of human neglect and thoughtless development, and insight into how these wetlands recover. Judith S. Weis and Carol A. Butler shed ample light on the human impact, including chapters on physical and biological alterations, pollution, and remediation and recovery programs. In addition to a national and global perspective, the authors place special emphasis on coastal wetlands in the Atlantic and Gulf regions, as well as the San Francisco Bay Area, calling attention to their historical and economic legacies. Written in clear, easy-to-read language, Salt Marshes proves that the battles for preservation and conservation must continue, because threats to salt marshes ebb and flow like the water that runs through them.

Book excerpt: In discussion with Ramsar’s Max Finlayson and Nick Davidson, and several members of the Society of Wetland Scientists, Springer is proposing the development of a new Encyclopedia of Wetlands, a comprehensive resource aimed at supporting the trans- and multidisciplinary research and practice which is inherent to this field. Aware both that wetlands research is on the rise and that researchers and students are often working or learning across several disciplines, we are proposing a readily accessible online and print reference which will be the first port of call on key concepts in wetlands science and management. This easy-to-follow reference will allow multidisciplinary teams and transdisciplinary individuals to look up terms, access further details, read overviews on key issues and navigate to key articles selected by experts.
Download or read book Concepts and Controversies in Tidal Marsh Ecology written by M.P. Weinstein and published by Springer Science & Business Media. This book was released on 2000-10-31 with total page 862 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tidal salt marshes are viewed as critical habitats for the production of fish and shellfish. As a result, considerable legislation has been promulgated to conserve and protect these habitats, and much of it is in effect today. The relatively young science of ecological engineering has also emerged, and there are now attempts to reverse centuries-old losses by encouraging sound wetland restoration practices. Today, tens of thousands of hectares of degraded or isolated coastal wetlands are being restored worldwide. Whether restored wetlands reach functional equivalency to `natural' systems is a subject of heated debate. Equally debatable is the paradigm that depicts tidal salt marshes as the `great engine' that drives much of the secondary production in coastal waters. This view was questioned in the early 1980s by investigators who noted that total carbon export, on the order of 100 to 200 g m-2 y-1 was of much lower magnitude than originally thought. These authors also recognized that some marshes were either net importers of carbon, or showed no net exchange. Thus, the notion of `outwelling' has become but a single element in an evolving view of marsh function and the link between primary and secondary production. The `revisionist' movement was launched in 1979 when stable isotopic ratios of macrophytes and animal tissues were found to be `mismatched'. Some eighteen years later, the view of marsh function is still undergoing additional modification, and we are slowly unraveling the complexities of biogeochemical cycles, nutrient exchange, and the links between primary producers and the marsh/estuary fauna. Yet, since Teal's seminal paper nearly forty years ago, we are not much closer to understanding how marshes work. If anything, we have learned that the story is far more complicated than originally thought. Despite more than four decades of intense research, we do not yet know how salt marshes function as essential habitat, nor do we know the relative contributions to secondary production, both in situ or in the open waters of the estuary. The theme of this Symposium was to review the status of salt marsh research and revisit the existing paradigm(s) for salt marsh function. Challenge questions were designed to meet the controversy head on: Do marshes support the production of marine transient species? If so, how? Are any of these species marsh obligates? How much of the production takes place in situ versus in open waters of the estuary/coastal zone? Sessions were devoted to reviews of landmark studies, or current findings that advance our knowledge of salt marsh function. A day was also devoted to ecological engineering and wetland restoration papers addressing state-of-the-art methodology and specific case histories. Several challenge papers arguing for and against our ability to restore functional salt marshes led off each session. This volume is intended to serve as a synthesis of our current understanding of the ecological role of salt marshes, and will, it is hoped, pave the way for a new generation of research.

Download or read book Climate Change Impacts to the Tidal Salt Marsh Habitats of San Pablo Bay California written by Karen Maria Thorne and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The response of ecosystems to climate change is difficult to evaluate and predict, and often are constrained by anthropogenic modifications to the natural environment. Here, I assess the impacts of sea-level rise and extreme storm events on a tidal salt marsh ecosystem located in San Francisco Bay estuary (California, USA) that contains local endemic and endangered wildlife species. The San Francisco Bay estuary has been heavily impacted from human development resulting in the loss of over 80% of its historic tidal salt marshes. In this dissertation, I hypothesize that there will be short-term impacts from extreme storm events and long-term impacts from sea-level rise on the San Pablo Bay endemic marsh wildlife. The first chapter of this dissertation is a discussion about the current state of understanding about climate change impacts on salt marsh habitats and wildlife, using San Pablo Bay National Wildlife Refuge (SPBNWR) as a case study. The second chapter documents two extreme storm events in 2010 and 2011, and discusses impacts on available marsh habitats. At peak storm surge, over 65% (2010) and 93% (2011) of the marsh habitat for wildlife was under water, presumably increasing predation and drowning risk. In the third chapter, I evaluate if SPBNWR is currently keeping pace with sea-level rise and what biogeomorphic processes may be important. Subsidence and accretion was found to vary spatially, with only 37% of the marsh keeping pace with current sea-level rise rates. Surprisingly, I found widespread subsidence (55%) in areas adjacent to constructed levees. Using Akaike Information Criterion (AICc), I found that the distance from the sediment source (San Pablo Bay edge) was the most important covariate to determine accretion. In the fourth chapter, I develop a spatially-explicit, sea-level rise response model for SPBNWR to assess habitat resiliency to 2100. The model projected a loss of most high marsh habitat by 2050, and a loss of most mid marsh habitat by 2040 to 2060. Low marsh habitat showed a temporary increase in area between 2030 and 2050, with the peak (658 ha) in 2040. A large eastern portion of the marsh or 75% of the area (1,004 ha) converted to predominantly mudflat by 2060 with a 47 cm increase in sea-level. However, an almost complete conversion to mudflat occurred with a 75 cm sea-level rise by 2080, with
