Book excerpt: The international journal Ecohydrology & Hydrobiology (E&H) has been created to promote the concept of Ecohydrology, which is defined as the study of the functional interrelations between hydrology and biota at the catchment scale. Ecohydrology extends from the molecular level to catchment-scale processes and is based on three principles: • framework (hydrological principle) - quantification and integration of hydrological and ecological processes at a basin scale; • target (ecological principle) - necessity of enhancing ecosystem absorbing capacity and ecosystem services; and • management tool (ecological engineering) – the use of ecosystem properties for regulation the interplay between hydrology and biota. The journal encourages the submission of manuscripts which adopt an integrative approach to aquatic sciences, explaining ecological and hydrological processes at a river-basin scale or propose practical applications of this knowledge. It will also consider papers in other hydrobiological fields. Especially welcome are papers on regulatory mechanism within biocenosis and the resistance and resilience of freshwater and costal zones ecosystems. There is no page charge for published papers. All submitted papers, written exclusively in English, should be original works, unpublished and not under consideration for publication elsewhere. All papers are peer-reviewed. The following types of papers are considered for publication in E&H: • original research papers • invited or submitted review papers, • short communications

Download or read book Effects of Reservoir Releases on Tailwater Ecology written by and published by . This book was released on 1981 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document presents a review of the often contradictory literature describing the effects of release waters on the tailwater environment and biota. The physical and chemical conditions found in tailwaters downstream from warmwater and coldwater discharge impoundments are compared and contrasted to those found in natural streams. Reservoir discharges modify the physical, chemical, and biological characteristics of the stream ecosystem. Physical and chemical characteristics in tailwaters are primarily determined by the depth, volume, and schedule of water releases. The magnitude of change is related to the type of reservoir and to the design and operation of outlet structures. The structure of the biotic community reflects the physical and chemical conditions existing in a particular tailwater. The community is composed of organisms, including nonnative species, that are adapted to this environment. The effects of the tailwater environment on the life history, physiology, and abundance of selected species are described.

Download or read book The Ecology of Regulated Streams written by James Ward and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for an international symposium on regulated streams was conceived over an open-faced sandwich at the R&dhus in Copenhagen when we attended the Congress of the Societas Internationalis Lim nologiae in summer 1977. Although· we were aware that various col leagues were working on ecological problems in reservoir tailwaters, we did not fully comprehend the magnitude of worldwide stream regu lation nor the extent of interest in the subject. Such revelations are reflected in the 21 papers included in this book. The authors have summarized current understanding of the ecology of regulated streams and attempted to convey the importance and direction of future scientific investigations in stream ecosystems altered by upstream impoundments. The First International Symposium on Regulated Streams was the plenary event at the 27th annual meeting of the North American Benthological Society, April 18-20, 1979, in Erie, Pennsylvania. More than 500 colleagues attended. We gratefully acknowledge the support granted by the National Science Foundation; these funds permitted intellectual exchange between scientists from eight coun tries on four continents. We extend personal thanks to Dr. K. W. Stewart, President of NABS, and the NABS Program Committee, including Drs. E. C. Masteller, E. R. Brezina, and W. P. Kovalak. These individuals and other officers and members of the Executive Committee assisted us with the many details leading to organization and staging of a scientific forum. Discussions with Dr. John Cairns, Jr. and Dr. G. Richard Marzolf during the early planning stage were most helpful.

This book was released on 2012-12-06 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brian D. Clark PADC Environmental Impact Assessment and Planning Unit Project Director Events throughout the world substantiate the view that planning and decision-making systems need a better integration of environ mental, economic and social considerations. Many organizations are showing considerable interest in Environmental Impact Assessment (EIA) and its role in project planning and policy evaluation and as an aid to decision-making. Consequently, it was decided to hold a NATO Advanced Study Institute on EIA for the following reasons. First there is evidence of uncertainty, particularly amongst many scientists and decision-makers, as to the nature, scope and object ives of EIA. Secondly, there is much confusion over the objectives and utility of certain EIA methods. Third, there appears to be a gulf developing between decision-makers and what they require from EIA, and the ability of the scientist to provide information which is scientifically rigorous. Finally, there appears to be little concern as to the relationship between "impact prediction" and the actual consequences ofa development activity, suggesting that if EIA is not to become both politically and scientifically disreput able greater emphasis should be placed on prediction, monitoring and post-audit studies. As will be seen from the contents of this volume the ASI attempted to address all of the above topics and indeed many more. It was perhaps inevitable that the ASI raised more questions than were answered but this is indicative of the vigorous debate that is now taking place about the role and utility of EIA.

Available in PDF, EPUB and Kindle. Book excerpt: Researchers and managers of regulated river systems will find this volume useful in acquiring information for deciding an integrated management plan for regulated river operations. Rather than the ecological theory of impacts of flow regulation, emphasis has been placed on methods to predict water quality and habitat alterations, as well as techniques to mitigate impacts from various operational scenarios. Although most chapters refer to impacts of riverine impoundments, these alternatives apply to any regulated situation in which changes in water quality or flow pattern occur. The predictive modeling techniques are explained primarily from a theoretical background. However, extensive bibliographies can guide the uninitiated to specific texts and software. Where controversial techniques have been presented, alternate methods are also described. Major topic areas include water quality problems, channel modification and management, ecological modeling and management, as well as a section on perspectives for ecological management and special problems in developing nations.

Download or read book Ecology of Atlantic Salmon and Brown Trout written by Bror Jonsson and published by Springer Science & Business Media. This book was released on 2011-05-03 with total page 720 pages. Available in PDF, EPUB and Kindle. Book excerpt: Destruction of habitat is the major cause for loss of biodiversity including variation in life history and habitat ecology. Each species and population adapts to its environment, adaptations visible in morphology, ecology, behaviour, physiology and genetics. Here, the authors present the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms of growth, migration, spawning and recruitment. Salmonids appeared as freshwater fish some 50 million years ago. Atlantic salmon and brown trout evolved in the Atlantic basin, Atlantic salmon in North America and Europe, brown trout in Europe, Northern Africa and Western Asia. The species live in small streams as well as large rivers, lakes, estuaries, coastal seas and oceans, with brown trout better adapted to small streams and less well adapted to feeding in the ocean than Atlantic salmon. Smolt and adult sizes and longevity are constrained by habitat conditions of populations spawning in small streams. Feeding, wintering and spawning opportunities influence migratory versus resident lifestyles, while the growth rate influences egg size and number, age at maturity, reproductive success and longevity. Further, early experiences influence later performance. For instance, juvenile behaviour influences adult homing, competition for spawning habitat, partner finding and predator avoidance. The abundance of wild Atlantic salmon populations has declined in recent years; climate change and escaped farmed salmon are major threats. The climate influences through changes in temperature and flow, while escaped farmed salmon do so through ecological competition, interbreeding and the spreading of contagious diseases. The authors pinpoint essential problems and offer suggestions as to how they can be reduced. In this context, population enhancement, habitat restoration and management are also discussed. The text closes with a presentation of what the authors view as major scientific challenges in ecological research on these species.
