Book excerpt: Restoration and construction of tidal marshes has been encouraged to recover ecosystem structure and function in response to wetland loss. While natural and restored marshes often achieve similar structure, they may not function similarly. Further, the effects of nutrient loading on ecological functions may vary between natural and restored or constructed marshes, with consequences for marsh resilience to sea-level rise. As coastal restoration and creation projects become more common, it is important to understand the similarities and differences in tidal marsh responses to environmental changes, including nutrient enrichment, and their impacts on ecosystem functions and resilience. To test the effects of nutrients on marsh responses, I conducted a controlled, nutrient-enrichment mesocosm experiment (none: no nutrients added; low: 20 g N m-2 yr-1 and 1.25 g P m-2 yr-1 added; high: 40 g N m-2 yr-1 /2.5 g P m-2 yr-1 added) utilizing intact, vegetated sods of Juncus roemerianus collected from natural and constructed tidal marshes along the Fowl River in Alabama. During the 8-month experiment, I measured hydro-edaphic conditions, above- and belowground biomass, primary production, organic matter decomposition, nitrate reduction potentials, and surface elevation change. Above- and belowground biomass was significantly higher in the natural than the constructed marsh, and belowground biomass responded positively to high nutrient additions. As a result, biomass allocation tended to shift belowground with increasing nutrients. Both marsh type and nutrient treatment significantly affected decomposition of J. roemerianus shoot litter, but not of belowground litter. However, given the lower belowground biomass in the constructed marsh, decomposition could have a greater overall impact on elevation in the constructed marsh compared to the natural marsh. Nitrate reduction potentials also differed between marshes and in response to nutrient enrichment. Denitrification (DN) was greater in the natural marsh and increased in response to nutrient additions in both marshes, representing nitrogen removal from the system. Dissimilatory nitrate reduction to ammonium (DNRA) did not differ between marshes or among nutrient treatments in the absence of carbon amendments, but it increased significantly in the natural marsh with carbon amendments, representing nitrogen retention in the system. These biological responses were insufficient to stimulate elevation gains, however, as all mesocosms lost elevation over time. While there were no significant differences in elevation change between marshes or among nutrient treatments, the none treatment retained the most elevation in the natural marsh while the high nutrient treatment retained the most elevation in the constructed marsh. Such differences between marsh types have important implications for coastal restoration success under increasingly eutrophic conditions, and collectively, indicate that nutrient additions may contribute differently to resilience to sea-level rise in natural and constructed tidal marshes.

Book excerpt: Coastal wetlands provide human populations with a multitude of ecosystem services, but they are increasingly threatened by sea-level rise and other simultaneously changing environmental conditions. To avoid drowning as water levels rise, coastal wetlands must maintain their surface elevations relative to mean sea level through feedbacks between physical and biological processes. Environmental changes that alter biological processes of production and decomposition will likely affect the capacity of these ecosystems to regulate their elevation and keep pace with sea-level rise. Changing environmental conditions such as elevated CO2, eutrophication, and hurricane sediment deposition have the potential to change production - decomposition dynamics by changing patterns of primary production, biomass allocation, community composition, or litter chemistry. To investigate the effects of climate change and nutrient enrichment on biological contributions to elevation maintenance, I conducted a series of multi-factor experiments, in both the field and greenhouse, which were designed to elucidate mechanistic pathways involved in elevation maintenance. The first study revealed that the biological response to storm sediment deposition was largely dependent on the position of the soil surface relative to sea level, and that elevated CO2 may help stabilize the new sediment addition in the long-term. Additionally, species-specific responses to flooding largely dictated the extent to which experimental wetland sods gained elevation over time. The second and third studies demonstrated that elevated CO2 may indirectly alter rates of decomposition of plant organic matter by driving shifts in biomass allocation to belowground organs or by altering community composition to favor the C3 species. Furthermore, the last study revealed that microbial decomposition was less than expected given the strong influences of plant species, tissue type and nutrient growth conditions on litter quality, suggesting that macrodetritivores also play an important role in litter processing, especially for shoot material. Collectively, these findings suggest that the capacity for biological contributions to elevation are largely determined by species-specific responses to changing environmental conditions, including CO2, storm-sediment inputs, sea-level rise, and nutrient enrichment. Thus, environmental changes that alter plant community composition or biomass allocation may have important consequences for biological feedbacks to elevation through their effects on plant production and organic matter decomposition.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal wetlands, including tidal marshes, impart a wide variety of ecosystem services, including organic matter (OM) production and carbon (C) storage. However, approximately 25% to 50% of the world's vegetated coastal habitat has been destroyed in the past 50 years, representing a massive loss of C-sink capacity. Wetland restoration presents an opportunity to recover this ecosystem function, but significant temporal lags in the restoration of OM production, decomposition, and storage have been recorded for many constructed marshes. The cycling of OM is regulated, in part, by above- and belowground production. It also is regulated by litter decomposition, a microbially-mediated process, yet microbial biomass and community composition often differ between natural and constructed marshes. Decomposition is also controlled by plant litter quality, but little is known about how litter quality differs between constructed and natural marshes. These potential differences in biological structure and ecosystem function between constructed and natural marshes warrant further exploration, as they may have important consequences for OM accumulation and C storage. In this study, I asked: (1) Do constructed marshes and naturally occurring tidal marshes differ in their biological structure, including above- and belowground plant biomass and fungal biomass? and (2) What factors are driving differences in OM decomposition and soil organic matter (SOM) pools between constructed and natural marshes? To answer these questions, I quantified decomposition rates of Juncus roemerianus shoot tissue in one natural and two constructed tidal marshes along the Alabama Gulf Coast. In addition to mass loss, I measured litter quality (C, N, P, lignin), fungal biomass, above- and belowground biomass, and SOM in all three marshes. While shoot litter quality was similar, above- and belowground biomass, fungal biomass on shoot litter, aboveground decomposition rates, and SOM were all greater in the natural marsh than in the constructed marshes. Soil organic C pools in the pine savannas and natural marshes were roughly two and ten times, respectively, of those in the constructed marshes. These results suggest that, while some aspects of biological structure are similar among sites, rates of OM processing and C-storage potential in these constructed marshes have not yet reached functional equivalency with the natural marsh 33 years after their creation, nor are they comparable to the OM stored in the forests from which they were constructed. Even so, estimates of C accumulation rates over the 33-year period since creation are similar to those reported for other coastal wetlands, making marsh construction a potentially beneficial strategy to recover ecosystem services in the long term.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The globally important nature of wetland ecosystems has led to their increased protection and restoration as well as their use in engineered systems. Underpinning the beneficial functions of wetlands are a unique suite of physical, chemical, and biological processes that regulate elemental cycling in soils and the water column. This book provides an in-depth coverage of these wetland biogeochemical processes related to the cycling of macroelements including carbon, nitrogen, phosphorus, and sulfur, secondary and trace elements, and toxic organic compounds. In this synthesis, the authors combine more than 100 years of experience studying wetlands and biogeochemistry to look inside the black box of elemental transformations in wetland ecosystems. This new edition is updated throughout to include more topics and provide an integrated view of the coupled nature of biogeochemical cycles in wetland systems. The influence of the elemental cycles is discussed at a range of scales in the context of environmental change including climate, sea level rise, and water quality. Frequent examples of key methods and major case studies are also included to help the reader extend the basic theories for application in their own system. Some of the major topics discussed are: Flooded soil and sediment characteristics Aerobic-anaerobic interfaces Redox chemistry in flooded soil and sediment systems Anaerobic microbial metabolism Plant adaptations to reducing conditions Regulators of organic matter decomposition and accretion Major nutrient sources and sinks Greenhouse gas production and emission Elemental flux processes Remediation of contaminated soils and sediments Coupled C-N-P-S processes Consequences of environmental change in wetlands# The book provides the foundation for a basic understanding of key biogeochemical processes and its applications to solve real world problems. It is detailed, but also assists the reader with box inserts, artfully designed diagrams, and summary tables all supported by numerous current references. This book is an excellent resource for senior undergraduates and graduate students studying ecosystem biogeochemistry with a focus in wetlands and aquatic systems.

Available in PDF, EPUB and Kindle. Book excerpt: Submerged soils and the wetlands they support are of huge practical importance: in global element cycles, as centres of biodiversity, in global food production. They are also uniquely interesting scientifically because of their peculiar biogeochemistry and the adaptations of plants and microbes to it. This book describes the physical, chemical and biological processes operating in submerged soils and governing their properties. It describes the transport processes controlling the fluxes of gases and solutes through the soil; the interchange of solutes between solid, liquid and gas phases; reduction and oxidation processes; biological processes in the soil and overlying water; and processes in the roots and rhizospheres of wetland plants. The dynamics of nutrients, toxins, pollutants and trace gases are then discussed in terms of these processes and in relation to wetland productivity and global element cycles. Written by a renowned expert in the field, this work will be invaluable to earth, environmental and agricultural scientists concerned with natural or man-made wetlands, and to advanced undergraduate and graduate studen ts of these topics.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The ocean has absorbed a significant portion of all human-made carbon dioxide emissions. This benefits human society by moderating the rate of climate change, but also causes unprecedented changes to ocean chemistry. Carbon dioxide taken up by the ocean decreases the pH of the water and leads to a suite of chemical changes collectively known as ocean acidification. The long term consequences of ocean acidification are not known, but are expected to result in changes to many ecosystems and the services they provide to society. Ocean Acidification: A National Strategy to Meet the Challenges of a Changing Ocean reviews the current state of knowledge, explores gaps in understanding, and identifies several key findings. Like climate change, ocean acidification is a growing global problem that will intensify with continued CO2 emissions and has the potential to change marine ecosystems and affect benefits to society. The federal government has taken positive initial steps by developing a national ocean acidification program, but more information is needed to fully understand and address the threat that ocean acidification may pose to marine ecosystems and the services they provide. In addition, a global observation network of chemical and biological sensors is needed to monitor changes in ocean conditions attributable to acidification.

Available in PDF, EPUB and Kindle. Book excerpt: The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
