Download or read book Estuarine Nutrient Cycling The Influence of Primary Producers written by Søren Laurentius Nielsen and published by Springer Science & Business Media. This book was released on 2005-02-08 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a well-known fact that eutrophication of coastal waters causes significant changes in the species composition of the primary producers. Usually a shift from an ecosystem dominated by sea grasses or large brown algae to an ecosystem dominated by fast-growing green algae or phytoplankton is observed. While this shift has been documented in a number of research papers and books, the consequences of this shift are less well known. This book focuses on the consequences of such changes for nutrient cycling. The aim is to investigate how different types of primary producers influence nutrient cycling in coastal marine waters, and how nutrient cycling changes qualitatively and quantitatively as a consequence of the changes in the primary producer community caused by eutrophication. The various chapters address specific ecological processes such as grazing, decomposition, burial and export of biomass from the ecosystem. The book is intended for researchers and professionals working in the field of coastal marine ecology and estuarine ecology and for advanced students in this field.

Available in PDF, EPUB and Kindle. Book excerpt: In all fields of science today, data are collected and theories are developed and published faster than scientists can keep up with, let alone thoroughly digest. In ecology the fact that practitioners tend to be divided between such subdisciplines as aquatic and terrestrial ecology, as well as between popula tion, community, and ecosystem ecology, makes it even harder for them to keep up with all relevant research. Ecologists specializing in one sub discipline are not always aware of progress in another subdiscipline that relates to their own. Syntheses are frequently needed that pull together large bodies of information and organize them in ways that makes them more coherent, and thus more understandable. I have tried to perform this task of integration for the subject area that encompasses the interrelationships between the dynamics of ecological food webs and the cycling of nutrients. I believe this area cuts across many of the subdisciplines of ecology and is pivotal to our progress in understanding ecosystems and in dealing with human impacts on the environment. Many current ecological problems involve human disturbances of both food webs and the nutrients that cycle through them. Little progress can be made towards elucidating the complex feedback relations inherent in the study of nutrient cycles in ecological systems without the tools of mathematics and computer modelling. These tools are therefore liberally used throughout the book.

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 Nutrient Cycling by Large Consumers at Individual Population and Ecosystem Levels written by Jonathan D. Ebel and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Organisms modulate nutrient cycles by transforming, storing, and transporting nutrients. While the impact of microorganisms and autotrophs on local and global biogeochemical cycles is well studied, our understanding of the nutrient cycling role of macro-consumers is in its infancy. In the following thesis, I explore aspects of the role of aquatic vertebrates in ecosystem nutrient cycling. Recent studies demonstrate substantial intraspecific variability in body element composition arising from environmental conditions and ontogeny. First, I test whether body element concentration varies among life stages and populations of Atlantic salmon (Salmo salar) from three Newfoundland rivers. I demonstrate that most intraspecific variability is explained by life stage and inter-stage variability in element concentrations can be attributed to the energy and nutrient requirements of reproduction and migration. Second, using long-term population monitoring data, I test whether ontogenetic differences in body phosphorus (P) concentration influence the role of Atlantic salmon as net sources or sinks of freshwater P. I find that incorporating inter-stage variability in body composition into nutrient flux models qualitatively changes our assessment of these populations as P sources or sinks relative to assuming ontogenetic homogeneity of body P concentration. Third, I develop a framework to describe the stoichiometric traits of vertebrate populations and use the framework to evaluate ontogenetic variability in body stoichiometry and total nutrient storage in brook trout (Salvelinus fontinalis) populations and partition nutrients released by migrating Atlantic salmon between eggs and excretion. Finally, life history strategy may influence interspecific variation in the ecosystem effects of migratory animals. I derive a two ecosystem model to investigate the ecosystem effects of migratory top consumers as subsidies. I formalized the hypothesis that iteroparous migratory animals should have stronger top-down effects on their biotic resource stocks than semelparous migratory animals, and that the response of ecosystem fluxes depends on the efficiency of consumer-mediated nutrient recycling. Overall, my findings suggest that interactions between ontogenetic development and life history strategy shape the nutrient cycling role of vertebrates. Connecting population structure and dynamics to nutrient cycles in this way may be a new path for 21st century ecological research and wildlife management.
Download or read book Biogeochemistry of Estuaries written by Thomas S. Bianchi and published by Oxford University Press. This book was released on 2006-09-14 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biogeochemistry of Estuaries offers a comprehensive and interdisciplinary approach to understanding biogeochemical cycling in estuaries. Designed as a text for intermediate to advanced students, this book utilizes numerous illustrations and an extensive literature base to impart the current state-of-the-art knowledge in this field. While many of the existing books in estuarine science are comprised of edited volumes, typically focused on highly specific topics in estuaries,Biogeochemistry of Estuaries provides, for the first time, a unique foundation in the areas of geomorphology, geochemistry, biochemistry, aqueous chemistry, and ecology, while making strong linkages (trhoughout the text) to ecosystem-based processes in estuarine sciences. Estuaries, located at the interface between land and the coastal ocean are dynamic, highly productive systems that, in many cases, have been historically associated with development of many of the great centers of early human civilization. Consequentially, these systems have and continue to be highly impacted by anthropogenic inputs. This timely book takes the foundational basis of elemental cycling in estuarine and applies it to estuarine management issues. Biogeochemistry of Estuaries will be welcomed by estuarine/marine scientists, ecologists, biogeochemists, and environmentalists around the world.
Download or read book Eutrophication in Coastal Ecosystems written by Jesper H. Andersen and published by Springer Science & Business Media. This book was released on 2010-05-30 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal eutrophication has been and still remains an important issue for the scientific community. Despite many efforts to mitigate coastal eutrophication, the problems associated with eutrophication are still far from being solved. This book focusses on the most recent scientific results in relation to specific eutrophication issues, e.g. definition(s) and causes; nutrient loads, cycling and limitation; reference conditions, primary effects and secondary effects; trend reversal (oligotrophication), as well as links to other pressures (climate change and top/down control). It also focusses on monitoring and modelling of coastal eutrophication, and adaptive and science-based nutrient management strategies. The book is based on selected papers from the Second International Symposium on Research and Management of Eutrophication in Coastal Ecosystems, held 20-23 June 2006 in Nyborg, Denmark.
