Download or read book Eutrophication Processes in Coastal Systems written by Robert J. Livingston and published by CRC Press. This book was released on 2000-11-27 with total page 350 pages. Available in PDF, EPUB and Kindle. Book excerpt: Derived from an unprecedented research effort covering over 31 years in a series of studies of 7 major river-estuaries, Eutrophication Processes in Coastal Systems presents a comprehensive and current review of the nature of the eutrophication process and how short- and long-term nutrient loading affects marine systems. This unique book is the culmination of the most advanced research to date on how coastal systems work. Based on an 11 year interdisciplinary study of the Perdido Bay System, Dr. Robert J. Livingston's groundbreaking work offers evidence for significant findings such as: Nutrient concentration gradients in fresh water as it entered the bay were stimulatory to phytoplankton blooms Species that showed distinctive seasonal and interannual successions dominated plankton blooms High relative dominance of bloom species was associated with significant reduction of phytoplankton species richness and diversity The blooms were associated with major reductions of infaunal and epibenthic macroinvertibrates, forcing a serious disruption of the food webs and losses of secondary production Eutrophication Processes in Coastal Ecosystems goes beyond its innovative analyses of how estuarine and coastal systems have responded to fundamental alterations of the eutrophication process. Dr. Livingston's book presents the case that bloom impacts must be reviewed against the background conditions that include periodic changes brought on by drought and anthropogenous dredging. It points to the critical need for further study of phytoplankton communities and the connection between plankton blooms, sediment deterioration, and low secondary production.
Download or read book The Structure and Function of Aquatic Microbial Communities written by Christon J. Hurst and published by Springer. This book was released on 2019-05-13 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses how aquatic microbial communities develop interactive metabolic coordination both within and between species to optimize their energetics. It explains that microbial community structuration often includes functional stratification among a multitude of organisms that variously exist either suspended in the water, lodged in sediments, or bound to one another as biofilms on solid surfaces. The authors describe techniques that can be used for preparing and distributing microbiologically safe drinking water, which presents the challenge of successfully removing the pathogenic members of the aquatic microbial community and then safely delivering that water to consumers. Drinking water distribution systems have their own microbial ecology, which we must both understand and control in order to maintain the safety of the water supply. Since studying aquatic microorganisms often entails identifying them, the book also discusses techniques for successfully isolating and cultivating bacteria. As such, it appeals to microbiologists, microbial ecologists and water quality scientists.

Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
Download or read book Microbiology of wetlands written by Paul Bodelier and published by Frontiers E-books. This book was released on 2013-07-08 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Watersaturated soil and sediment ecosystems (i.e. wetlands) are ecologically as well as economically important systems due to their high productivity, their nutrient (re)cycling capacities and their prominent contribution to global greenhouse gas emissions. Being on the transition between terrestrial and – aquatic ecosystems, wetlands are buffers for terrestrial run off thereby preventing eutrophication of inland as well as coastal waters. The close proximity of oxic-anoxic conditions, often created by wetland plant roots, facilitates the simultaneous activity of aerobic as well as anaerobic microbial communities. Input of nutrients and fast recycling due to active aerobes and anaerobes makes these systems highly productive and therefore attractive for humans as well as many other organisms. Wetlands globally are under high pressure due to anthropogenic activities as well as climate change. Changes of land-use as well as altered hydrology due to climate change will lead to disturbance and loss of these habitats. However, the diversity and functioning of microbial communities in wetlands systems in highly underexplored in comparison to soils and aquatic ecosystems. Given the importance of wetlands and their immediate threats combined with the lack of knowledge on the microbiology of these systems is the basis for this special issue, focusing on the current microbiological knowledge and gaps therein to be assessed in future wetland research. Papers (research papers, reviews, perspectives, opinion papers) are welcomed that focus on all aspects that regulate the functioning and community composition of microbes (i.e. bacteria, archaea, protozoa, fungi) in wetland ecosystems (peat, coastal as well as freshwater marshes, flood plains, rice paddies, littoral zones of lakes etc) from all geographic regions. Welcomed topics are physiology, ecology, functioning, biodiversity, biogeography of microbes involved in nutrient cycling (C, N, P, Fe, Mn), green house gas emissions as well as plant-microbe interactions. These studies can be multidisciplinary and cover topics from the molecular to the community level.

This book was released on 2013-11-11 with total page 513 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume focuses on the nutrient and organic matter inputs in estuaries and other coastal ecosystems, their effects on geochemistry and community structure and possibilities for recovery of the systems to a trophic state that is beneficial for man and nature. The book provides many examples of the effects of the enhanced supply of nutrients and organic matter on the chemical features of the water and on the structure, metabolism and trophic pathways of the biological communities. Also included are several case studies providing considerable insight into the response of the different coastal ecosystems to long term changes in the trophic state of the water. Current knowledge on modeling as a tool to manage the trophic state of the coastal ecosystems is also dealt with, making this book one of interests to scientist and students as well as managers.
Download or read book Estuaries and Nutrients written by Bruce J. Neilson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuaries are eternally enriched. Their positions at the foot of watersheds and their convenience as receiving bodies for the wastes of cites, towns and farms results in continuous addition of nutrients - those elements and compounds which are essential for organic production. Such materials must be added to these complex bodies of water to sustain production, since there is a net loss of water and its contents to the oceans. Enrichment from land and the ocean and the subsequent cycling of the original chemicals or their derivatives contribute to the extraordinarily high values of estuaries for human purposes. Many estuaries are able to assimilate large quantities of nutrients despite the great fluctuations which occur with variations in the flow from tributaries. The nutrients can be stored, incorporated in standing crops of plants, released, cycled and exported - and the system frequently achieves high production of plants and and animals without creation of any undesirable results of enrichment. Excessive enrichment with the same elements and compounds can, however, be highly detrimental to estuaries and their uses. Coastal cities are usually located on the estuaries which provided a harbor for the- and which now receive partially treated sewage and other wastes from the expanding population and industrial activity. Conversion of woodlands to agricultural use and the extensive application of fertilizers have resulted in the flow of large quantities of nutrients down the hill or slopes and eventually into the estuary.
Download or read book Trophic Organization in Coastal Systems written by Robert J. Livingston and published by CRC Press. This book was released on 2002-12-23 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Derived from an unprecedented research effort covering over 70 field years of field data in a series of studies, Trophic Organization in Coastal Systems represents an alternative approach to coastal research that has been successfully applied to coastal resource management issues. This unique book is based upon a sequence of long-term, interdisciplinary studies of a series of coastal regions in the NE Gulf of Mexico that include nutrient loading, habitat definition, quantified collections of organisms from microbes to fishes, and the determination of the trophic organization that defines the processes that shape the productivity of these areas. A multidisciplinary team of marine scientists, chemists, physical oceanographers, geologists, hydrologists, engineers, experimental biologists, and taxonomists have created a singular database of changes in a series of Gulf of Mexico coastal systems. This field information, together with field and laboratory experimentation, is integrated with the scientific literature to advance our understanding of how coastal food webs work. The central focus is on the relationship of primary production in the form of species-specific phytoplankton communities with associated food webs of coastal systems and the relationship of tropho-dynamic processes to long-term changes (natural and polluted) in such areas. The impacts of phytoplankton blooms on trophic organization is elucidated. The author, a renowned marine scientist, provides detailed knowledge of the processes that drive coastal ecosystems. He presents an in-depth discussion of a hierarchy of cyclical periods associated with the formation and development of aquatic food webs. Trophic Organization in Coastal Systems will be particularly useful to those involved in research related to the importance of aquatic food webs to an understanding of how aquatic systems function. The principles and processes of trophic organization presented here can serve as a valuable model for research in other regions of the world.
