Freshwater Fisheries Ecology

Freshwater Fisheries Ecology PDF Author: John F. Craig
Publisher: John Wiley & Sons
ISBN: 1118394402
Category : Technology & Engineering
Languages : en
Pages : 920

Book Description
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.

Encyclopedia of Inland Waters

Encyclopedia of Inland Waters PDF Author:
Publisher: Academic Press
ISBN: 0123706262
Category : Science
Languages : en
Pages : 2589

Book Description
Inland aquatic habitats occur world-wide at all scales from marshes, swamps and temporary puddles, to ponds, lakes and inland seas; from streams and creeks to rolling rivers. Vital for biological diversity, ecosystem function and as resources for human life, commerce and leisure, inland waters are a vital component of life on Earth. The Encyclopedia of Inland Waters describes and explains all the basic features of the subject, from water chemistry and physics, to the biology of aquatic creatures and the complex function and balance of aquatic ecosystems of varying size and complexity. Used and abused as an essential resource, it is vital that we understand and manage them as much as we appreciate and enjoy them. This extraordinary reference brings together the very best research to provide the basic and advanced information necessary for scientists to understand these ecosystems – and for water resource managers and consultants to manage and protect them for future generations. Encyclopedic reference to Limnology - a key core subject in ecology taught as a specialist course in universitiesOver 240 topic related articles cover the field Gene Likens is a renowned limnologist and conservationist, Emeritus Director of the Institute of Ecosystems Research, elected member of the American Philosophical Society and recipient of the 2001 National Medal of Science Subject Section Editors and authors include the very best research workers in the field

The Atna River

The Atna River PDF Author: Odd Terje Sandlund
Publisher: Springer Science & Business Media
ISBN: 1402022549
Category : Science
Languages : en
Pages : 220

Book Description
This volume presents a unique set of time series data concerning the environmental and biological dynamics of a pristine alpine-boreal river system in Norway. A simultaneous collection of data on climate, hydrology, erosion, water chemistry, primary production, invertebrates and fish provides an unusual insight into the ecology of a watercourse characteristic of this region of north-western Europe. Individual papers present data collected over 14 years, which provides an opportunity to understand the natural dynamics in a system with very little direct influence from human activities. The results indicate a level of variation that should be expected in natural systems, and provides a solid basis for a discussion of the best approach to the monitoring of biological diversity and environmental factors in rivers and lakes. The volume is aimed at researchers working with watershed management and aquatic sciences. It provides useful information and experiences of particular relevance to the implementation of the EU Frame Directive for Water.

Critical Loads and Dynamic Risk Assessments

Critical Loads and Dynamic Risk Assessments PDF Author: Wim de Vries
Publisher: Springer
ISBN: 9401795088
Category : Science
Languages : en
Pages : 671

Book Description
This book provides a unique overview of research methods over the past 25 years assessing critical loads and temporal effects of the deposition of air pollutants. It includes critical load methods and applications addressing acidification, eutrophication and heavy metal pollution of terrestrial and aquatic ecosystems. Applications include examples for each air pollution threat, both at local and regional scale, including Europe, Asia, Canada and the US. The book starts with background information on the effects of the deposition of sulphur, nitrogen and heavy metals and geochemical and biological indicators for risk assessments. The use of those indicators is then illustrated in the assessment of critical loads and their exceedances and in the temporal assessment of air pollution risks. It also includes the most recent developments of assessing critical loads and current and future risks of soil and water chemistry and biodiversity under climate change, with a special focus on nitrogen. The book thus provides a complete overview of the knowledge that is currently used for the scientific support of policies in the field of air pollution control to protect ecosystem services.

Book Description
1. In this book I have published my Ph.D. work. 2. This book has been written in a simple and comprehensible language. 3. The important laws, concepts examples and principles have been given in the simple form to help the students to focus on them. 4. This book is intended to serve as a conceptual book for the students of B.Sc. M.Sc and for those preparing for Ph.D. as well as S.E.T./N.E.T. the work which has been written in this book is just a small attempt in the area of studying the pollutants and their dynamics. It is therefore possible that the work may be extended further.

Climate Change Impacts on Freshwater Ecosystems

Climate Change Impacts on Freshwater Ecosystems PDF Author: Martin Kernan
Publisher: John Wiley & Sons
ISBN: 1444391275
Category : Science
Languages : en
Pages : 470

Book Description
This text examines the impact of climate change on freshwater ecosystems, past, present and future. It especially considers the interactions between climate change and other drivers of change including hydromorphological modification, nutrient loading, acid deposition and contamination by toxic substances using evidence from palaeolimnology, time-series analysis, space-for-time substitution, laboratory and field experiments and process modelling. The book evaluates these processes in relation to extreme events, seasonal changes in ecosystems, trends over decadal-scale time periods, mitigation strategies and ecosystem recovery. The book is also concerned with how aspects of hydrophysical, hydrochemical and ecological change can be used as early indicators of climate change in aquatic ecosystems and it addresses the implications of future climate change for freshwater ecosystem management at the catchment scale. This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students.
