Available in PDF, EPUB and Kindle. Book excerpt: ANOXIA defines the lack of free molecular oxygen in an environment. In the presence of organic matter, anaerobic prokaryotes produce compounds such as free radicals, hydrogen sulfide, or methane that are typically toxic to aerobes. The concomitance of suppressed respiration and presence of toxic substances suggests these habitats are inhospitable to Eukaryota. Ecologists sometimes term such environments 'Death Zones'. This book presents, however, a collection of remarkable adaptations to anoxia, observed in Eukaryotes such as protists, animals, plants and fungi. Case studies provide evidence for controlled beneficial use of anoxia by, for example, modification of free radicals, use of alternative electron donors for anaerobic metabolic pathways, and employment of anaerobic symbionts. The complex, interwoven existence of oxic and anoxic conditions in space and time is also highlighted as is the idea that eukaryotic inhabitation of anoxic habitats was established early in Earth history.

Download or read book Fish Physiology Hypoxia written by Jeffrey G. Richards and published by Academic Press. This book was released on 2009-03-10 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Periods of environmental hypoxia (Low Oxygen Availability) are extremely common in aquatic systems due to both natural causes such as diurnal oscillations in algal respiration, seasonal flooding, stratification, under ice cover in lakes, and isolation of densely vegetated water bodies, as well as more recent anthropogenic causes (e.g. eutrophication). In view of this, it is perhaps not surprising that among all vertebrates, fish boast the largest number of hypoxia tolerant species; hypoxia has clearly played an important role in shaping the evolution of many unique adaptive strategies. These unique adaptive strategies either allow fish to maintain function at low oxygen levels, thus extending hypoxia tolerance limits, or permit them to defend against the metabolic consequences of oxygen levels that fall below a threshold where metabolic functions cannot be maintained. The aim of this volume is two-fold. First, this book will review and synthesize the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure and place them within an environmental and ecological context. Second, through the development of a synthesis chapter this book will serve as the cornerstone for directing future research into the effects of hypoxia exposures on fish physiology and biochemistry. - The only single volume available to provide an in-depth discussion of the adaptations and responses of fish to environmental hypoxia - Reviews and synthesizes the adaptive behavioural, morphological, physiological, biochemical, and molecular strategies used by fish to survive hypoxia exposure - Includes discussion of the evolutionary and ecological consequences of hypoxia exposure in fish
Download or read book Bridging Boundaries Through Regional Marine Research written by National Research Council and published by National Academies Press. This book was released on 2000-03-06 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: As appreciation of the interdisciplinary and multidimensional character of environmental issues has increased, there have been attempts to address regional needs more directly. One of these, the Regional Marine Research Program (RMRP), was established by Congress in 1990 to provide a mechanism to fund coastal marine research based on regionally-defined priorities. The RMRP legislation established a system of nine regional marine research boards around the United States. Each board was responsible for planning marine research to address issues of water quality and ecosystem health on a regional scale. Although all nine regions received funding for planning activities and development of a research plan, only the Gulf of Maine RMRP received funding for program implementation. The completion of the Gulf of Maine program, in 1997, presents an opportunity to evaluate whether the process for planning and managing the Gulf of Maine research was adequate, whether the research fulfilled the goals of the program, and whether this experience should serve as a model for similar regional programs elsewhere. Bridging Boundaries through Regional Marine Research is a study of the RMRP, with a specific review of the Gulf of Maine program as well as an assessment of other modesl for regional marine research. This report assesses the need for regional marine research,reviews processes by which regional marine research needs can be defined, and discusses existing programs for regional marine research in the United States. It also identifies short- and long-term approaches that might be taken by NOAA.
Download or read book Coastal Ecosystem Processes written by Daniel M. Alongi and published by CRC Press. This book was released on 2020-11-25 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal Ecosystem Processes, written by the renowned marine scientist Daniel Alongi, describes how pelagic and benthic food webs, from beaches and tidal flats to the continental edge, process energy and matter. This volume focuses on recent advances and new developments on how food webs are closely intertwined with the geology, chemistry, and physics of coastal seas. Dr. Alongi presents a process-functional approach as a way of understanding how the energetics of coastal ecosystems rely not only on exchanges within and between food chains, but how such functions are influenced by terrigenous and atmospheric processes. There is a need for documentation and an awareness of just how necessary, yet delicate, is the interplay of biological and physical forces between coastal ocean, land, and the atmosphere. Marine scientists today need to make informed management decisions about sustainable development and conservation of these fragile ecosystems. Coastal Ecosystem Processes provides present and future marine scientists the latest coastal ecosystem information to make the right decisions concerning the ecology of our oceans.

Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-07-17 with total page 421 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 Sedimentary Environments Offshore Norway Palaeozoic to Recent written by O.J. Martinsen and published by Elsevier. This book was released on 2001-06-06 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: Required reading for geologists working in the offshore areas, Volume 10 continues the series from the Norwegian Petroleum Society. This work provides an up-to-date review of the late Palaeozoic to present sedimentary history of the Norwegian offshore areas in the North Sea and Mid-Norway basins. Case studies, overview articles and analogue examples from adjacent areas such as Greenland and Denmark, present new ideas on the development of the Norwegian margin from the Carboniferous through the Mesozoic and Cenozoic.In particular, new evidence and interpretations are presented on well-known major reservoir-bearing successions such as the Statfjord Formation and Dunlin Group in the Northern North Sea, and the Åre and the Tilje Formations in the Mid-Norway area. Furthermore, the Upper Jurassic succession in the Haltenbanken area is described, giving new evidence on the interplay between extensional tectonics and sedimentation during the second major rift phase in the area.The Cretaceous and Cenozoic periods are treated extensively, showing their importance as overall deep water sedimentary systems with proven and potential reservoir rocks, such as in the Ormen Lange Field, and for causing burial of Jurassic rocks to advantageous depths for hydrocarbon generation. The Recent sedimentary history of the Norwegian margin is treated with examples of the glacial history and giant submarine slides which understanding is vital for the placement of offshore installations.The book is organised based on geologic time, from Palaeozoic through Mesozoic to Cenozoic examples. It includes a set of palaeogeographic maps from the Carboniferous through to the Cenozoic. In addition, there are numerous examples of core photographs, well log data, correlation panels and seismic as well as outcrop photographs and logs from the analogue examples. Comprehensive reference and keyword lists are also included.
