Download or read book Freshwater Fisheries Ecology written by John F. Craig and published by John Wiley & Sons. This book was released on 2016-01-12 with total page 920 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inland fisheries are vital for the livelihoods and food resources of humans worldwide but their importance is underestimated, probably because large numbers of small, local operators are involved. Freshwater Fisheries Ecology defines what we have globally, what we are going to lose and mitigate for, and what, given the right tools, we can save. To estimate potential production, the dynamics of freshwater ecosystems (rivers, lakes and estuaries) need to be understood. These dynamics are diverse, as are the earths freshwater fisheries resources (from boreal to tropical regions), and these influence how fisheries are both utilized and abused. Three main types of fisheries are illustrated within the book: artisanal, commercial and recreational, and the tools which have evolved for fisheries governance and management, including assessment methods, are described. The book also covers in detail fisheries development, providing information on improving fisheries through environmental and habitat evaluation, enhancement and rehabilitation, aquaculture, genetically modified fishes and sustainability. The book thoroughly reviews the negative impacts on fisheries including excessive harvesting, climate change, toxicology, impoundments, barriers and abstractions, non-native species and eutrophication. Finally, key areas of future research are outlined. Freshwater Fisheries Ecology is truly a landmark publication, containing contributions from over 100 leading experts and supported by the Fisheries Society of the British Isles. The global approach makes this book essential reading for fish biologists, fisheries scientists and ecologists and upper level students in these disciplines. Libraries in all universities and research establishments where biological and fisheries sciences are studied and taught should have multiple copies of this hugely valuable resource. About the Editor John Craig is Editor-in-Chief of the Journal of Fish Biology and has an enormous range of expertise and a wealth of knowledge of freshwater fishes and their ecology, having studied them around the globe, including in Asia, North America, Africa, the Middle East and Europe. His particular interests have been in population dynamics and life history strategies. He is a Fellow of the Linnean Society of London and the Royal Society of Biology.
Download or read book Oceanography and Marine Biology written by R.N. Hughes and published by CRC Press. This book was released on 2016-11-25 with total page 906 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever-increasing interest in oceanography and marine biology and their relevance to global environmental issues create a demand for authoritative reviews summarizing the results of recent research. Oceanography and Marine Biology: An Annual Review has catered to this demand since its founding by the late Harold Barnes more than 50 years ago. Its objectives are to consider, annually, the basic areas of marine research, returning to them when appropriate in future volumes; to deal with subjects of special and topical importance; and to add new subjects as they arise. The favourable reception and complimentary reviews accorded to all the volumes shows that the series is fulfilling a very real need. Volume 54 follows closely the objectives and style of the earlier volumes, continuing to regard the marine sciences—with all their various aspects—as a unity. Physical, chemical, and biological aspects of marine science are dealt with by experts actively engaged in these fields. The series is an essential reference text for researchers and students in all fields of marine science and related subjects, and it finds a place in libraries of universities, marine laboratories, research institutes and government departments. It is consistently among the highest ranking series in terms of impact factor in the marine biology category of the citation indices compiled by the Institute for Scientific Information/Web of Science.
Download or read book Gulls and Plovers written by C.J. Barnard and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the early years of this century a Scottish doctor speculated on the evolutionary origin of human tears. It seemed to him that with the increase in brain size and cognitive powers of our early ancestors many events in the struggle for existence would be just too distressing to observe. How comforting then, for the mother, distraught by the sight of her child being devoured by a lion, to cloud her vision with a flood of tears! Just so, though if the good doctor had pondered further, the following picture might have occurred to him, comfortable in his speculative armchair, and given him some pause for thought. ' ~ . . . . ~ . . ~ ~ . . •. . u" . . , ~- . ' _ . . . . . . . vii viii SERIES EDITOR'S FOREWORD These stories do not, of course, get us very far in understanding the evolution of tears or anything else, but they do remind us how far the study of behavioural adaptation has come this century. This is, in fact, an exciting time for students of behaviour. The last twenty years have seen a great advance in the theoretical armoury for tackling questions of behavioural evolution and adaptation, and a parallel expansion in empirical studies, particularly in the field. The concepts of inclusive fitness and the evolutionarily stable strategy, for example, have helped to explain major features of social behaviour and have generated entirely new questions and predictions for the field worker to examine.
Download or read book Tidal Flat Ecology written by Karsten Reise and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tidal coastline presents a fascinating ecological world. Rocky shores with their recurrent zonation of algae and sessile invertebrates demonstrate the orderliness of nature, apparently obeying general explan atory principles. The niche theory could just as well have hatched out of the tight species-packing on the coral reef flats. Fluxes of carbon and nitrogen are best studied in mangroves and salt marshes with their outstanding primary productivity; the bare mud and sands of the tidal flats are different. Their ecological treasures are well concealed, and perhaps not to everybody's taste. Pick up a piece of tidal sediment and see how it resembles a large, rotten cheese! It smells, is slimy and sticky, is punched with holes and crowded with various worms. Tidal flats receive detritus from both the land and the sea. They sup port a rich benthic community which attracts birds from far distant breeding grounds, and serves as a nursery for crabs, shrimp and fish. Tidal flats are a busy ecological turntable. They import low valued organic matter, and they export well-fed birds to the land and grown-up fish to the sea. They offer ideal opportunities for aquaculture but are also used as dumping grounds for industrial wastes. All this may call for a marine ecologist to investigate the basic processes involved. Yet there is still another reason.

Available in PDF, EPUB and Kindle. Book excerpt: Estuarine and coastal waters are acknowledged centres for anthropogenic impacts. Superimposed on the complex natural interactions between land, rivers and sea are the myriad consequences of human activity – a spectrum ranging from locally polluting effluents to some of the severest consequences of global climate change. For practitioners, academics and students in the field of coastal science and policy, this timely book examines and exemplifies current and future challenges: from upper estuaries to open coasts and adjacent seas; from tropical to temperate latitudes; from Europe to Australia. This authoritative volume marks the 50th anniversary of the Estuarine and Coastal Sciences Association. Drawing on the expertise of more than 60 specialist contributors, individual chapters address coastal erosion and deposition; open shores to estuaries and deltas; marine plastics; coastal squeeze and habitat loss; tidal freshwaters – saline incursion and estuarine squeeze; restoration management using remote data collection; carbon storage; species distribution and non-natives; shorebirds; Modelling environmental change; physical processes such as sediments and modelling; sea level rise and estuarine tidal dynamics; estuaries as fish nurseries; policy versus reality in coastal conservation; developments in estuarine, coastal and marine management. In addition to providing an overview of current scientific understanding, the material gathered here offers a clear-eyed perspective on what needs to be done to protect these fragile – and vital – ecosystems.

Download or read book The Oosterschelde Estuary The Netherlands a Case Study of a Changing Ecosystem written by P.H. Nienhuis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Oosterschelde estuary is one of the estuaries in the Netherlands which remained after the Delta scheme was completed in 1986. In the seventies the Oosterschelde became a national symbol of the change in political thinking and decision making about the values of our natural environment. As a result of political decision a storm surge barrier was built in the mouth of the estuary, as a compromise between safety for the human population and nature conservation. Owing to the broad interest in the meaning of the Oosterschelde estuary for Dutch and international societies, it became one of the most intensively studied coastal ecosystems in Western Europe. In an interdisciplinary approach of several state agencies and universities, a broad spectrum of physical, chemical and biological research has been carried out during the period of 1980--1989, dedicated to the structure and functioning of the saline ecosystem. The undisturbed estuary was studied during the period between 1980--1984. Large mathematical models had been constructed before 1986, to simulate future changes in the ecosystem. Further studies after the completion of the storm surge barrier (1986--1989) have been used for verification of the model. The integrated and summarized knowledge of the Oosterschelde ecosystem is used by water managers and nature and fisheries conservationists. A case study for professional civil engineers, ecologists, marine biologists, water managers, decision makers, university students and anyone interested in physical, chemical and biological estuarine and coastal sciences.
Download or read book The Biology of Estuarine Management written by James Wilson and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estuaries are the interface between man and the sea. and they are the channels for the impact of man on the marine environment. Because they are to a greater or lesser extent connected to the sea. they have traditionally been regarded as part of that seemingly infinite resource. or at best an open-ended means of access to it. This approach has led to conflicts between the users of the estuary. and with the increase not only in population but more particularly in the developed countries in manufacturing output. these conflicts have become more and more acute . The estuary should always be regarded as a resource. and a finite resource at that. and the problem in management is to optimise the use of that resource. It is clearly wasteful and inefficient not to use it to its full capacity. and this includes both overuse of the system. such that the whole thing collapses. and underuse. in which there is still spare capacity for one use or another. The objective of this book is to explore the uses to which estuaries are put and the means by which the performance of the system under load may be assessed. It seems appropriate here to mention that although this book will be talking about estuaries. the majority of it will be applicable also to lagoons. semi-enclosed bays and other such systems.
Download or read book Behavioral Adaptation to Intertidal Life written by Guido Chelazzi and published by Springer. This book was released on 2013-12-20 with total page 519 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NATO Advanced Research Workshop on "Behavioural Adaptation to Intertidal Life" held in Castiglioncello, Italy (May, 1987) was attended by 50 participants, most of whom presented requested lectures. It was perhaps the first time that specialists of various animal groups, from cnidarians to birds, were able to meet and discuss the importance of behavioural adaptation to this peculiar, sometimes very harsh environment. But the taxonomic barrier is not the only one which the meeting attemped to over come. Lately, the research on intertidal biology has spread from pure taxonomy and static analysis of community structure to such dynamic aspects as intra- and interspecific relationships, and physiological mechanisms aimed at avoiding stress and exploitation of limited-resources. This increasing interest stems not only from an inclination for this particular ecological system and some of its typical inhabitants, but also from the realization that rocky and sandy shore communities are suitable models for testing and improving some global theories of evolutionary biology, behavioural ecology and sociobiology. The number of eco-physiological and eco-ethological problems emerging from the study of intertidal animals is fascinatingly large and a complete understanding of this environment cannot be reached using a strictly "reductionistic" or a pure "holistic" approach.
Download or read book The Estuarine Ecosystem written by Donald S. McLusky and published by OUP Oxford. This book was released on 2004-04-29 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: For the inhabitants of many of the world's major towns and cities, estuaries provide their first and nearest glimpse of a natural habitat. Despite the attempts of man to pollute or reclaim it, the estuarine ecosystem continues to provide a fascinating insight into a natural world where energy is transformed from sunlight into plant material, and then through the steps of a food chain is converted into a rich food supply for birds and fish. The book provides a concise readable introduction to estuarine ecology. First published in 1981, it soon established itself as the principle textbook of choice in the UK & NW Europe. This new edition builds upon the strengths of the earlier editions but has been thoroughly revised throughout. The new co-author brings a human impact dimension to the revised book. It is written for advanced undergraduate and graduate students (particularly taught masters) who have had a general ecology course, but no further training in estuarine science. It will be useful to both professional researchers and practical managers in marine ecology and environmental science who seek a compact but comprehensive introduction to estuarine ecology.
Download or read book Foraging Behavior written by A.C. Kamil and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 671 pages. Available in PDF, EPUB and Kindle. Book excerpt: Foraging behavior has always been a central concern of ecology. Understanding what animals eat is clearly an essential component of under standing many ecological issues including energy flow, competition and adaptation. Theoretical and empirical developments in the late 1960's and 1970's led to a new emphasis in the study of foraging behavior, the study of individual animals in both field and laboratory. This development, in turn, led to an explosion of interest in foraging. Part of the reason for this explosion is that when foraging is studied at the individual level, it is relevant to many disciplines. Behaviorists, including ethologists and psychologists, are interested in any attempt to understand behavior. Ecologists know that a better understanding of foraging will contribute to resolving a number of important ecological issues. Anthropologists and others are applying the ideas coming out of the study of foraging behavior to problems within their disciplines. These developments led to a multidisciplinary symposium on foraging behavior, held as part of the 1978 Animal Behavior Society meetings in Seattle, Washington. Many ecologists, ethologists and psychologists participated or attended. The symposium was very successful. generating a high level of excitement. As a result, the participants decided to publish the proceedings of the symposium (Kami1 & Sargent 1981).
