Lipids in Aquatic Ecosystems by Michael T. Arts,Michael T. Brett,Martin Kainz Pdf

Evidence now suggests that the roles of essential fatty acids as growth promoters and as indices of health and nutrition are fundamentally similar in freshwater and marine ecosystems. Lipids in Aquatic Ecosystems integrates this divergent literature into a coordinated, digestible form. Chapters are organized so as to discuss and synthesize the flow of lipids from lower to higher trophic levels, up to and including humans. Linkages between the production, distribution and pathways of these essential compounds within the various levels of the aquatic food webs, and their ultimate uptake by humans and other terrestrial organisms, are highlighted throughout the book. This book will be of interest to researchers and resource managers working with aquatic ecosystems.

Anthropogenic Pollution of Aquatic Ecosystems by Donat-P. Häder,E. Walter Helbling,Virginia E. Villafañe Pdf

This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.

Light and Photosynthesis in Aquatic Ecosystems by John T. O. Kirk Pdf

Beginning systematically with the fundamentals, the fully-updated third edition of this popular graduate textbook provides an understanding of all the essential elements of marine optics. It explains the key role of light as a major factor in determining the operation and biological composition of aquatic ecosystems, and its scope ranges from the physics of light transmission within water, through the biochemistry and physiology of aquatic photosynthesis, to the ecological relationships that depend on the underwater light climate. This book also provides a valuable introduction to the remote sensing of the ocean from space, which is now recognized to be of great environmental significance due to its direct relevance to global warming. An important resource for graduate courses on marine optics, aquatic photosynthesis, or ocean remote sensing; and for aquatic scientists, both oceanographers and limnologists.

Body Size: The Structure and Function of Aquatic Ecosystems by Alan G. Hildrew,David G. Raffaelli,Ronni Edmonds-Brown Pdf

Ecologists have long struggled to predict features of ecological systems, such as the numbers and diversity of organisms. The wide range of body sizes in ecological communities, from tiny microbes to large animals and plants, is emerging as the key to prediction. Based on the relationship between body size and features such as biological rates, the physics of water and the amount of habitat available, we may be able to understand patterns of abundance and diversity, biogeography, interactions in food webs and the impact of fishing, adding up to a potential 'periodic table' for ecology. Remarkable progress on the unravelling, describing and modelling of aquatic food webs, revealing the fundamental role of body size, makes a book emphasising marine and freshwater ecosystems particularly apt. In this 2007 book, the importance of body size is examined at a range of scales that will be of interest to professional ecologists, from students to senior researchers.

Aquatic Ecosystems by Marvin Snyder Pdf

The seagrass meadows of the Northeast Coast of Brazil have the greatest area, biomass, biometrics and diversity of the Brazilian Coast. In this region, the seagrass diversity and plasticity may vary due to differences in environmental factors. Some natural aspects of the coastal environment or that which affect the coastal zone, mainly climatic (seasons of rains and winds) and geomorphological (bathymetry and substrate type), cause variations in seasonality and plasticity of the species, respectively. Chapter One in this book on aquatic ecosystems summarises the available information concerning how seagrass vary along the Northeast Coast of Brazil, as well as other ecological information. Chapter Two presents a brief historical overview of biological indicators, considering the assessment of water quality through microalgae from an environmental perspective and their role as natural bioindicators of the effects of eutrophication. Chapter Three provides a mixing zone analysis of surface brine discharges in coastal waters. Chapter Four studies the effect of low salinity on intertidal blue mussels from the White Sea.

Light and Photosynthesis in Aquatic Ecosystems by John T. O. Kirk Pdf

Penetration of light into aquatic ecosystems is greatly affected by the absorption and scattering processes that take place within the water. Thus within any water body, the intensity and colour of the light field changes greatly with depth and this has a marked influence on both the total productivity of, and the kinds of plant that predominate in, the ecosystem. This study presents an integrated and coherent treatment of the key role of light in aquatic ecosystems. It ranges from the physics of light transmission within water, through the biochemistry and physiology of aquatic photosynthesis, to the ecological relationships which depend on the underwater light climate.

Acidic Deposition and Aquatic Ecosystems by Donald F. Charles,Susan Christie Pdf

Acidic deposition and its effect on aquatic ecosystems have become major scientific and public policy issues in the United States since the early 1970s, and many diverse studies have been completed. This book is the first comprehensive, integrated synthesis of available information on current and potential effects of acidic precipitation on lakes and streams in geographic regions with a high number of low-alkalinity surface water from the Adirondacks and the Southern Blue Ridge to the Upper Midwest to the Rocky Mountains, the Sierra Nevada, and the Cascades. Written by leading authors, the book examines the current status of water chemistry and characterizes the processes controlling water chemistry on a regional basis by using and comparing high-quality data sets. Methods for the assessment of long-term changes in water chemistry and their effects in fish and other biota are also presented. The book amply illustrates the substantial diversity among geographical regions with respect to the nature of surface waters and the complexity of their response to acidic deposition. This volume will be of great interest to researchers in limnology, aquatic ecology, environmental chemistry, hydrology, and atmospheric sciences. It will also serve as an important reference for environmental managers and policy makers.
