Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Nutrient export from agricultural activities in the Lake Okeechobee watershed has contributed to eutrophication of the Lake and regulatory implementation of a phosphorus (P) Total Maximum Daily Load (TMDL) rule. Historically, anthropogenic manipulation of hydrology lowered water tables, creating improved conditions for upland forage grass production. This action also increased runoff rates and P loading to the Lake. Hydrologic restoration of historically isolated wetlands within the watershed is a proposed best management practice (BMP) to increase P retention capacities of these wetlands. However, longer hydroperiods could potentially decrease pasture productivity, and as a consequence, adversely affect the economic viability of the cattle industry in the region. Previous studies have shown that soils under longer hydroperiods in the Okeechobee watershed have greater P storage potential than surrounding upland soils. This research primarily focuses on the vegetative component of P storage in pasture wetlands. The objectives were to evaluate biomass production and P storage dynamics in vegetation under various hydroperiods and to determine the efficacy of using an alternative forage grass species to maintain pasture productivity after wetland restoration. Four isolated wetlands in Okeechobee County, Florida were sampled in November, 2004, March, 2005 and July 2005. In this study, total P storage in wetlands (with a 50 m upland buffer) included soil (10cm depth), below ground biomass (BGB), above ground biomass (AGB) and litter components.
Book Synopsis Phosphorus Release and Storage by Two Isolated Wetlands in the Northern Lake Okeechobee Drainage Basin by : Christy L. Sackfield

This book was released on 2022 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetland restoration has numerous potential ecological and societal benefits, one of which is the retention of phosphorus (P) and consequent protection of downstream water bodies from eutrophication. Past studies focused on influents to and effluents from a variety of wetland types have documented net P retention. However, some wetland systems are less effective at P capture and wetland P retention capacity can change over time. Certain wetland types - especially riparian wetlands restored on former agricultural land - remain understudied. In Vermont, most of the over 4000 potential wetland restoration sites in the Lake Champlain Basin are located on current or former agricultural fields, and little information is available to inform estimates of net P retention (i.e., P balances) for such sites. In this dissertation, I examined various factors affecting P balances in riparian wetlands restored on historically farmed soils of Vermont. P balance in a riparian wetland is largely a function of particulate P capture (e.g., deposition of particle-attached P during floods) and soluble reactive P (SRP) loss (e.g., release of SRP from soils). In Chapter 1, I determined the threshold in P saturation ratio (PSR) for riparian soils in Vermont, enabling calculation of a soil P storage capacity (SPSC) metric. I then quantified soil SRP release using intact soil core incubations with simulated floods for sites ranging from active farms to mature wetlands and confirmed that PSR, SPSC, and other soil parameters were strong predictors of SRP loss during inundation. In Chapter 2, I monitored P dynamics in soil, water, and vegetation at three restored riparian wetlands on former agricultural land in the Lake Champlain Basin, focusing on factors that affect P deposition and SRP release. At wetland sampling plots, observed inorganic sediment gain and decreased water column total suspended solids concentrations relative to the river/inflow indicated that wetlands were effectively trapping particles. Accretion of inorganic P (i.e., best estimate for mineral P deposited during floods) ranged from 0.1 to 1 g P m-2 yr-1 depending on site and elevation. Elevated SRP concentrations in wetland water columns relative to the river sources indicated internal SRP release from soils, and high frequency data indicated that factors such as temperature, dissolved oxygen, and primary production likely influence SRP dynamics. In Chapter 3, I developed a wetland P dynamics model that can generate estimates of net P retention from a simple set of soil and hydrologic inputs, considering both P deposition and SRP release. For proof of concept, I simulated the wetlands monitored in Chapter 2 using two years of monitoring data and a set of model scenarios. I found that net total P balance was typically positive (-0.04 to 0.24 g P m-2 yr-1), with average P retention efficiency of ~40%, though there was substantial variability depending on site and scenario. P retention efficiency was especially sensitive to changes in influent P and total suspended solids concentrations, with the greatest net P retention predicted for systems receiving influent floodwater with high P concentrations. Reduction of influent SRP concentrations promoted SRP release from soils, suggesting that legacy soil P in the wetlands might cause a time lag between the adoption of upstream best management practices and reduction in downstream SRP concentrations. In the future, the model developed in Chapter 3 can be applied more broadly to investigate the potential P retention benefits of wetland restoration at candidate sites across Vermont. Together, the information put forth by this dissertation provides a suite of data and tools that researchers and managers can use to enhance the P retention benefits of riparian wetland restoration.

Book Synopsis Biogeochemistry of Wetlands by : K. Ramesh Reddy
Download or read book Biogeochemistry of Wetlands written by K. Ramesh Reddy and published by CRC Press. This book was released on 2022-09-10 with total page 926 pages. 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.

Book Synopsis Review of the EPA's Economic Analysis of Final Water Quality Standards for Nutrients for Lakes and Flowing Waters in Florida by : National Research Council
Download or read book Review of the EPA's Economic Analysis of Final Water Quality Standards for Nutrients for Lakes and Flowing Waters in Florida written by National Research Council and published by National Academies Press. This book was released on 2012-07-05 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Environmental Protection Agency's estimate of the costs associated with implementing numeric nutrient criteria in Florida's waterways was significantly lower than many stakeholders expected. This discrepancy was due, in part, to the fact that the Environmental Protection Agency's analysis considered only the incremental cost of reducing nutrients in waters it considered "newly impaired" as a result of the new criteria-not the total cost of improving water quality in Florida. The incremental approach is appropriate for this type of assessment, but the Environmental Protection Agency's cost analysis would have been more accurate if it better described the differences between the new numeric criteria rule and the narrative rule it would replace, and how the differences affect the costs of implementing nutrient reductions over time, instead of at a fixed time point. Such an analysis would have more accurately described which pollutant sources, for example municipal wastewater treatment plants or agricultural operations, would bear the costs over time under the different rules and would have better illuminated the uncertainties in making such cost estimates.

Download or read book Restoration of Aquatic Ecosystems written by National Research Council and published by National Academies Press. This book was released on 1992-01-01 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

This book was released on 2012-12-06 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.
Book Synopsis Progress Toward Restoring the Everglades by : National Research Council
Download or read book Progress Toward Restoring the Everglades written by National Research Council and published by National Academies Press. This book was released on 2011-05-26 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although the progress of environmental restoration projects in the Florida Everglades remains slow overall, there have been improvements in the pace of restoration and in the relationship between the federal and state partners during the last two years. However, the importance of several challenges related to water quantity and quality have become clear, highlighting the difficulty in achieving restoration goals for all ecosystem components in all portions of the Everglades. Progress Toward Restoring the Everglades explores these challenges. The book stresses that rigorous scientific analyses of the tradeoffs between water quality and quantity and between the hydrologic requirements of Everglades features and species are needed to inform future prioritization and funding decisions.
Book Synopsis Ecological Effects of Water-level Fluctuations in Lakes by : Karl M. Wantzen
Download or read book Ecological Effects of Water-level Fluctuations in Lakes written by Karl M. Wantzen and published by Springer Science & Business Media. This book was released on 2009-05-06 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most aquatic ecosystems have variable water levels. These water-level fluctuations (WLF) have multiple effects on the organisms above and below the waterline. Natural WLF patterns in lakes guarantee both productivity and biodiversity, while untimely floods and droughts may have negative effects. Human impacts on WLF have led to a stabilization of the water levels of many lakes by hydraulic regulation, untimely drawdown due to water use, or floods due to water release from hydropower plants in the catchments. This book provides a first review in this field. It presents selected papers on the ecological effects of WLF in lakes, resulting from a workshop at the University of Konstanz in winter 2005. Issues addressed here include the extent of WLF, and analyses of their effects on different groups of biota from microorganisms to vertebrates. Applied issues include recommendations for the hydrological management of regulated lakes to reduce negative impacts, and a conceptual framework is delivered by an extension of the floodpulse concept for lakes. Current impacts on water use, including increasing demands on drinking and irrigation water, hydropower etc., and climate change effects on WLF make this book an essential resource for aquatic ecologists, engineers, and decision-makers dealing with the management of lake ecosystems and their catchments.

Book Synopsis Climate change: Unpacking the burden on food safety by : Food and Agriculture Organization of the United Nations
Download or read book Climate change: Unpacking the burden on food safety written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-03-01 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is causing unprecedented damage to our ecosystem. Increasing temperatures, ocean warming and acidification, severe droughts, wildfires, altered precipitation patterns, melting glaciers, rising sea levels and amplification of extreme weather events have direct implications for our food systems. While the impacts of such environmental factors on food security are well known, the effects on food safety receive less attention. The purpose of Climate change: Unpacking the burden on food safety is to identify and attempt to quantify some current and anticipated food safety issues that are associated with climate change. The food safety hazards considered in the publication are foodborne pathogens and parasites, harmful algal blooms, pesticides, mycotoxins and heavy metals with emphasis on methylmercury. There is also, a dedicated section on the benefits of forward-looking approaches such as horizon scanning and foresight, which will not only aid in anticipating future challenges in a shifting global food safety landscape, but also help build resilient food systems that can be continually updated as more knowledge is assimilated. By building a more widespread and better understanding of the consequences climate change has on food safety, it is hoped that this document will aid in fostering stronger international cooperation in making our food safer by reducing the global burden of these concerns.
