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 Macrophyte Communities of Lake Winnebago by : Mackenzie Lindstedt Kessenich
Download or read book Macrophyte Communities of Lake Winnebago written by Mackenzie Lindstedt Kessenich and published by . This book was released on 2012 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historical records from Lake Winnebago show minimal macrophyte growth; however, reports from recent years claim that macrophyte growth in some areas of the lake has reached nuisance levels. This study aimed to investigate the species of macrophytes present and their abundances in four near-shore locations, as well as measurements of multiple water quality conditions. Rake sampling was used to identify species and quantify their abundances and distributions. In addition, data were collected on light penetration, Secchi depths, and suspended algae chlorophyll concentrations at each site. These data from shallow near-shore sites reveal trends in changing water clarity and light penetration when compared to past and current data from deep-water sites. Macrophytes find habitats with increased light penetration advantageous for growth and competition; this suggests that the macrophyte species may have flourished recently due to comparatively better water clarity. In addition to two dominant native species, Coontail and Wild Celery, we also observed two invasive species (Eurasian Watermilfoil and Curly-leaf Pondweed). Eurasian Watermilfoil was found in high abundances in three out of the four sampling sites. Possible causes of increased water clarity, in particular the invasion of zebra mussels, will also be discussed. This study provides baseline data on the current macrophyte communities and will facilitate further exploration of recent changes in growth conditions that have resulted in such high abundances of macrophytes.

Book Synopsis Macrophyte Community Dynamics in Lake Simcoe's Fringe Wetlands by : Lindsey Aileen Jaanusson
Download or read book Macrophyte Community Dynamics in Lake Simcoe's Fringe Wetlands written by Lindsey Aileen Jaanusson and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Indices have been developed using macrophytes and water quality parameters to detect the impact of anthropogenic disturbance on coastal wetlands of the Great Lakes, but such an index does not currently exist for Lake Simcoe. As wetland macrophytes are influenced by water quality, any impairment in wetland quality should be reflected by taxonomic composition, biomass and dynamics of the macrophyte community. This study investigates the potential use of macrophytes as a tool for monitoring water quality by examining the dynamics (species richness, density, diversity, and above-ground biomass) in emergent macrophyte communities in fringe wetlands around Lake Simcoe exposed to contrasting degrees of disturbance. Macrophytes and limnologic data were collected from six wetlands over four seasons from 2013 - 2014. The macrophytes were identified to species and limnologic data was quantified to reflect the water quality, which was measured as a proxy for site disturbance. Wetlands in this study correspond to a wide range of environmental conditions, ranging from very clear and nutrient poor oligotrophic conditions (e.g., TP =11.25 μg/L, TN = 345.25 μg/L, CHL a =1.37 mg·m-3) to turbid and eutrophic wetlands (e.g., TP = 47.25 μg/L, TN = 2285 μg/L, CHL a = 3.26 mg·m-3. Overall, the limnologic parameters indicated that water quality reflected the degree of anthropogenic degradation influencing the wetland. Taxonomic composition and population dynamics reflected the water quality. The least disturbed site was dominated by native Scirpus acutus and Scirpus pungens, which are mostly intolerant of environmental degradation, as well as the cosmopolitan Sparganium eurycarpum, found in all sites and tolerant of many different conditions. The moderately disturbed sites were dominated by both intolerant and tolerant species, including Scirpus acutus, Leersia oryzoides, Eleocharis smallii, Typha x glauca, Typha angustifolia, and Sparganium eurycarpum. The highly disturbed sites were also dominated by Sparganium eurycarpum, and species that are considered to be invasive, aggressive, and/or very tolerant of degradation, including Typha x glauca, Typha angustifolia, Phragmites australis, and Calamagrostis canadensis. These species are indicator species of wetland integrity and their relationship with the limnologic parameters as determined by ordination demonstrated responses that were consistent with the literature. Thus this study validates that macrophytes could be used as an indicator of water quality changes in this study area.
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 Re-Engineering Water Storage in the Everglades by : National Research Council
Download or read book Re-Engineering Water Storage in the Everglades written by National Research Council and published by National Academies Press. This book was released on 2005-06-17 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Water Science and Technology Board and the Board on Environmental Studies and Toxicology have released the seventh and final report of the Committee on Restoration of the Greater Everglades Ecosystem, which provides consensus advice to the South Florida Ecosystem Restoration Task Force on various scientific and technical topics. Human settlements and flood-control structures have significantly reduced the Everglades, which once encompassed over three million acres of slow-moving water enriched by a diverse biota. To remedy the degradation of the Everglades, a comprehensive Everglades Restoration Plan was formulated in 1999 with the goal of restoring the original hydrologic conditions of its remaining natural ecosystem. A major feature of this plan is providing enough storage capacity to meet human needs while also providing the needs of the greater Everglades ecosystem. This report reviews and evaluates not only storage options included in the Restoration Plan but also other options not considered in the Plan. Along with providing hydrologic and ecological analyses of the size, location and functioning of water storage components, the report also discusses and makes recommendations on related critical factors, such as timing of land acquisition, intermediate states of restoration, and tradeoffs among competing goals and ecosystem objectives.
Book Synopsis Macrophyte and PH Buffering Updates to the Klamath River Water-Quality Model Upstream of Keno Dam, Oregon by : Annett Brigitte Sullivan
Download or read book Macrophyte and PH Buffering Updates to the Klamath River Water-Quality Model Upstream of Keno Dam, Oregon written by Annett Brigitte Sullivan and published by CreateSpace. This book was released on 2014-07-16 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: A hydrodynamic, water temperature, and water-quality model of the Link River to Keno Dam reach of the upper Klamath River was updated to account for macrophytes and enhanced pH buffering from dissolved organic matter, ammonia, and orthophosphorus. Macrophytes had been observed in this reach by field personnel, so macrophyte field data were collected in summer and fall (June-October) 2011 to provide a dataset to guide the inclusion of macrophytes in the model. Three types of macrophytes were most common: pondweed (Potamogeton species), coontail (Ceratophyllum demersum), and common waterweed (Elodea canadensis). Pondweed was found throughout the Link River to Keno Dam reach in early summer with densities declining by mid-summer and fall. Coontail and common waterweed were more common in the lower reach near Keno Dam and were at highest density in summer. All species were most dense in shallow water (less than 2 meters deep) near shore. The highest estimated dry weight biomass for any sample during the study was 202 grams per square meter for coontail in August. Guided by field results, three macrophyte groups were incorporated into the CE-QUAL-W2 model for calendar years 2006-09. The CE-QUAL-W2 model code was adjusted to allow the user to initialize macrophyte populations spatially across the model grid. The default CE-QUAL-W2 model includes pH buffering by carbonates, but does not include pH buffering by organic matter, ammonia, or orthophosphorus. These three constituents, especially dissolved organic matter, are present in the upper Klamath River at concentrations that provide substantial pH buffering capacity. In this study, CE-QUAL-W2 was updated to include this enhanced buffering capacity in the simulation of pH. Acid dissociation constants for ammonium and phosphoric acid were taken from the literature. For dissolved organic matter, the number of organic acid groups and each group's acid dissociation constant (Ka) and site density (moles of sites per mole of carbon) were derived by fitting a theoretical buffering response to measured upper Klamath River alkalinity titration curves. The organic matter buffering in the Klamath River was modeled with two monoprotic organic acids: carboxylic acids with a mean pKa of 5.584 and site density of 0.1925, and phenolic organic acids with a mean pKa of 9.594 and site density of 0.6466. Total inorganic carbon concentrations in the model boundary inputs were recalculated based on the new buffering equations. CE-QUAL-W2 was also adjusted to allow the simulation of nonconservative alkalinity caused by nitrification, denitrification, photosynthesis, and respiration. The Klamath River model was recalibrated after the macrophyte and pH buffering updates producing improved predictions for pH, dissolved oxygen, and particulate carbon.
Book Synopsis The Structuring Role of Submerged Macrophytes in Lakes by : Erik Jeppesen
Download or read book The Structuring Role of Submerged Macrophytes in Lakes written by Erik Jeppesen and published by Springer. This book was released on 1997-12-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Submerged macrophytes have been the object of intensive research, and a large body of literature exists on their growth, reproduction, and physiology. Several studies have focused on the interactions between submerged macrophytes and other autotrophic components and the impact of the plants on the dynamics of nutrients, dissolved organic and inorganic carbon, oxygen, and pH. Comparatively few studies have dealt with the ability of submerged macrophytes to modulate the structure and dynamics of pelagic and benthic food webs. Recently, however, the amount of research into the structuring role of submerged macrophytes in food webs has markedly increased, and the results obtained so far suggest that sub merged macrophytes are of significant importance for the food web interactions and environmental quality of lakes, even at relatively low areal plant coverage. For example, plants affect the interactions between predacious, planktivorous, and benthivorous fish and between fish and invertebrates, including key organisms such as large zooplankton and snails. Changes in these interactions in turn may have cascading effects on the entire food web in both the pelagial and the littoral zone. To provide a forum for discussion of recent results in this growing field of research and to define future research needs, a workshop was held on 16 to 20 June, 1996, at the Freshwater Centre in Silkeborg, Denmark. The present book is a result of the workshop. It is divided into three parts.
Book Synopsis Inluence of Water Level on Aquatic Macrophytes in the Dutch River Rhine by : S. Teurlincx
Download or read book Inluence of Water Level on Aquatic Macrophytes in the Dutch River Rhine written by S. Teurlincx and published by . This book was released on with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic macrophytes, as the name implies, are reliant upon the presence of water for the their growth and reproduction. This basic habitat requirement for aquatic macrophytes (Humphries, 1996) is not generally a focus of study in rivers in temperate regions. This is likely a cause of the continual lotic state of these rivers where water is continually present. Aquatic macrophytes however cannot grow at all depths and are vulnerable to drought. As such, even though water is present, depending on water level regime, suitable habitat may not be. This study strives to illustrate how the water level regime influences the potentially suitable habitat for aquatic macrophytes and if aquatic macrophyte abundance and occurrence can be explained by water level changes through time.
Book Synopsis Gas Transfer at Water Surfaces by : W. Brutsaert
Download or read book Gas Transfer at Water Surfaces written by W. Brutsaert and published by Springer Science & Business Media. This book was released on 1983-12-31 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transfer across the surface of environmental waters is of interest as an important phase in the geophysical and natural biochemical cycles of numer ous substances; indeed it governs the transition, one way or the other, be tween the dissolved state in the water and the gaseous state in the atmo sphere. Especially with increasing population and industrialization, gas transfer at water surfaces has become a critical factor in the understanding of the various pathways of wastes in the environment and of their engineering management. This interfacial mass transfer is, by its very nature, highly complex. The air and the water are usually in turbulent motion, and the interface be tween them is irregular, and disturbed by waves, sometimes accompanied by breaking, spray and bubble formation. Thus the transfer involves a wide variety of physical phenomena occurring over a wide range of scales. As a consequence, scientists and engineers from diverse disciplines and problem areas, have approached the problem, often with greatly differing analytical and experimental techniques and methodologies.
