Salt Marshes

by Judith S Weis, Salt Marshes Books available in Docs, PDF, EPUB, Mobi, Textbook, Kindle Format. Download Salt Marshes book, 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.

Vegetation Of Australian Riverine Landscapes

by Samantha Capon, Vegetation Of Australian Riverine Landscapes Books available in Docs, PDF, EPUB, Mobi, Textbook, Kindle Format. Download Vegetation Of Australian Riverine Landscapes book, Vegetation communities in Australia's riverine landscapes are ecologically, economically and culturally significant. They are also among the most threatened ecosystems on the continent and have been dramatically altered as a result of human activities and climate change. Vegetation of Australian Riverine Landscapes brings together, for the first time, the results of the substantial amount of research that has been conducted over the last few decades into the biology, ecology and management of these important plant communities in Australia. The book is divided into four sections. The first section provides context with respect to the spatial and temporal dimensions of riverine landscapes in Australia. The second section examines key groups of riverine plants, while the third section provides an overview of riverine vegetation in five major regions of Australia, including patterns, significant threats and management. The final section explores critical issues associated with the conservation and management of riverine plants and vegetation, including water management, salinity, fire and restoration. Vegetation of Australian Riverine Landscapes highlights the incredible diversity and dynamic nature of riverine vegetation across Australia, and will be an excellent reference for researchers, academics and environmental consultants.

Download Wetland Habitats Of North America book, "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

Impacts Of Fertilization On Salt Marsh Resilience

by Kenneth Michael Czapla, Impacts Of Fertilization On Salt Marsh Resilience Books available in Docs, PDF, EPUB, Mobi, Textbook, Kindle Format. Download Impacts Of Fertilization On Salt Marsh Resilience book, Salt marshes provide valuable ecosystem services to human society, but are currently under threat from accelerating sea level rise and nutrient enrichment. Carbon (C) and mineral accumulation allow salt marshes to maintain elevation above sea level and survive. Anthropogenic nitrogen (N) loading is increasing in many salt marshes, causing negative impacts on marsh resilience such as increased decomposition and decreased below-ground production. However, increasing N may also have simultaneous positive effects such as increased primary production and above-ground biomass, surface sediment accretion, and denitrification rates, which remove excess N from coastal waters. Many studies have been conducted to determine the effect of fertilization on salt marsh resilience; however, inconsistent conclusions across studies may result from varying physical and chemical characteristics across salt marsh locations that impact responses to fertilization. In this dissertation we performed experiments to determine how C cycling, C accumulation, N cycling, and microbial communities vary in both natural and fertilized salt marsh locations at Marine Corps Base Camp Lejeune, North Carolina, USA. Here we show that edge marsh with a high elevation berm had lower pore water sulfide, ammonium, dissolved organic C (DOC), and dissolved organic C (DIC) concentrations than interior marsh, which displayed longer pore water residence time and flooding duration with high pore water sulfide, ammonium, DOC, and DIC concentrations. Respiration and primary production were higher in the edge marsh compared to the interior marsh but net ecosystem CO2 exchange (NEE) was nearly balanced at all sites. Fertilization had a much greater impact on edge than interior NEE, shifting edge NEE toward net CO2 emission. Net ecosystem carbon balance (NECB), based on the mass balance of NEE, lateral C export, and sediment C deposition for edge and interior sites was calculated to examine the effect of fertilization on net C accumulation. NECB displayed a net C gain in the interior marsh but a large net C loss on the edge; fertilization stimulated more C loss on the edge than in the interior. When extrapolating NECB to the entire marsh, C loss on the edge greatly impacted the whole marsh C budget, causing the marsh to have a net loss of 53 kg C yr-1 under natural conditions and a five-fold increase in C loss with fertilization. N removal through denitrification was greater on the edge and increased with fertilization, but was not affected by fertilization at the site with highest sulfide concentrations. DNRA, which retains N in the marsh, dominated over denitrification only during summer, and varied widely across locations. Fertilization generally decreased DNRA rates. Microbial community composition was distinct on the edge vs. interior, with differences driven by the differences in pore water sulfide, ammonium, DOC, and DIC. The edge was a hotspot for nitrifying microbial communities. The processes of respiration and denitrification were positively correlated to the relative abundance of sulfate reducers and ammonia oxidizers, respectively. Thus, we conclude that fertilization had an overall negative effect on marsh resilience with especially large impacts on edge marsh.
