Available in PDF, EPUB and Kindle. Book excerpt: Author's abstract: Tidal marshes provide important economic and environmental functions. There are 1,745 km2 of tidal marsh habitat along the Georgia coast that can be separated into three distinct marsh types based on salinity levels. Tidal fresh, brackish, and salt marshes occur along a gradient that is maintained by tidal forces pushing inland and freshwater sources flowing towards the ocean. The edaphic environment associated with plant distributions in salt and brackish marshes is expected to change in response to rising sea levels and changing inundation patterns. My objective was to classify tidal marsh plants based on edaphic variables thought to influence plant distributions and elevation. Using classification and regression trees (CART), two statistical models were built. When all observations were combined the overall accuracy was 66%. Salinity was the most important variable in classifying observations as either salt or brackish. Elevation did not increase accuracy significantly (68%). When observations were separated into habitat specific models, overall accuracy of edaphic models increased to 80% for salt and brackish marshes. Elevation did not significantly increase accuracy, in the brackish and salt models, 81% and 78% respectively. Water content was the most important predictor variable in salt marshes and percent organic matter was most important in brackish marshes. Overall, CART models had higher accuracies when salt and brackish marsh observations were separated, indicating that habitat-specific analysis is preferable. This study showed that salt and brackish marshes differ significantly in edaphic environments and elevation. However, species-specific differences were complicated by overlapping habitat conditions for the majority of species examined. Edaphic conditions are an important factor driving plant zonation patterns, but can vary significantly over the course of hours. Geomorphic variables, like elevation, provide a stable alternative but may not correlate well over large coastal areas. Understanding how tidal marshes will change as sea levels rise will require a better understanding of these variables and how they influence tidal marshes. Several improvements are discussed that could enhance the accuracy and sampling protocol of this study.

Download or read book Halophytes for Food Security in Dry Lands written by Muhammad Ajmal Khan and published by Academic Press. This book was released on 2015-09-15 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Halophytes for Food Security in Dry Lands addresses the concerns surrounding global food scarcity, especially focusing on those living in arid and dry lands The book touches on food crises in dry regions of the world and proposes halophytes as an alternate source of consumption for such areas. Halophytes, those plants that thrive in saline soil and provide either food source options themselves, or positively enhance an eco-system’s ability to produce food, and are thus an important and increasingly recognized option for addressing the needs of the nearly 1/6 of the world’s population that lives in these arid and semi-arid climates. Including presentations from the 2014 International Conference on Halophytes for Food Security in Dry Lands, this book features insights from the leading researchers in the subject. It is a valuable resource that includes information on the nutritional value of halophytes, their genetic basis and potential enhancement, adaption of halophytes, and lessons learned thus far. Provides comprehensive coverage of the importance and utilization of halophytes to compensate the demand of food in whole world especially in the dry regions Contains insights from ecological to molecular fields Includes edible halophytes as well as those that enhance food-producing eco-systems Presents information for improving abiotic stress tolerance in plants

Available in PDF, EPUB and Kindle. Book excerpt: “Wetland Habitats of North America is essential reading for everyone who studies, manages, or visits North American wetlands. It fills an important void in the wetland literature, providing accessible and succinct descriptions of all of the continent’s major wetland types.” Arnold van der Valk, Iowa State University “Batzer and Baldwin have compiled the most comprehensive compendium of North American wetland habitats and their ecology that is presently available—a must for wetland scientists and managers.” Irving A. Mendelssohn, Louisiana State University "If you want to gain a broad understanding of the ecology of North America’s diverse wetlands, Wetland Habitats of North America is the book for you. Darold Batzer and Andrew Baldwin have assembled an impressive group of regional wetland scientists who have produced a virtual encyclopedia to the continent’s wetlands. Reading the book is like a road trip across the Americas with guided tours of major wetland types by local experts. Your first stop will be to coastal wetlands with eight chapters covering tidal wetlands along the Atlantic, Gulf, and Pacific coasts. Then you’ll travel inland where you can visit any or all of 18 types ranging from bottomland swamps of the Southeast to pothole marshes of the Northern Prairies to montane wetlands of the Rockies to tropical swamps of Central America and desert springs wetlands. All in one book—I’m impressed! Every wetlander should add this book to her or his swampland library. Ralph Tiner, University of Massachusetts–Amherst

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.
