The book is based on data collected during the past 10 years by Zackenberg Ecological Research Operations (ZERO) at Zackenberg Research Station in northeast Greenland. This volume covers the function of Arctic ecosystems based on the most comprehensive long-term data set in the world from a well-defined Arctic ecosystem. Editors offer a comprehensive and authoritative analysis of how climate variability is influencing an Arctic ecosystem and how the Arctic ecosystems have inherent feedback mechanisms interacting with climate variability or change. - The latest research on the functioning of Arctic ecosystems - Supplements current books on Arctic climate impact assessment as a case study for ecological specialists - Discusses the complex perpetuating effects on Earth - Vital information on modeling ecosystem responses to understand future climates
This thematic volume represents an important and exciting benchmark in the study of food webs and other ecological networks, synthesizing and showcasing current research and highlighting future directions for the development of the field. - Updates and informs the reader on the latest research findings - Written by leading experts in the field - Highlights areas for future investigation
The aim of this book is to provide an accessible, up-to-date introduction to stream and river biology. Beginning with the physical features that define running water habitats, the book goes on to look at these organisms and their ecology.
This thematic volume represents an important and exciting benchmark in the study of integrative ecology, synthesizing and showcasing current research and highlighting future directions for the development of the field.
This book is intended for those with an academic, scientific and practical interest in river conservation and management. It provides an overview of how changes in legislation, policies, institutional responsibilities, science, technology, practical techniques and public perception have influenced how rivers have been managed over the past 20 years and the challenges that lie ahead during the next 20 years. The book is based on the international conference River Conservation and Management:20 Years On held at York. Thirty-one chapters, with contributions from North and South America, Europe, Asia and Australasia provide a wide-ranging perspective on this complex but profoundly important subj...
A hugely important text for advanced undergraduates as well as graduates with an interest in stream and river ecology, this second, updated edition is designed to serve as a textbook as well as a working reference for specialists in stream ecology and related fields. The book presents vital new findings on human impacts, and new work in pollution control, flow management, restoration and conservation planning that point to practical solutions. All told, the book is expanded in length by some twenty-five percent, and includes hundreds of figures, most of them new.
The most recent volume of this series, Advances in Ecological Research, demonstrates a captivating knowledge of recent advances in the analysis of food webs. A food web describes the network of predator-prey interactions within a community. The simplest description of a food web specifies only who eats whom (a connectance web), with no indication of how much or how often. Chapters in this book begin with a discussion of the most detailed connectance webs ever compiled, and advance to incorporate information on the body size and numerical abundance of the species. The results yield new ways of describing food webs and powerful new models for estimating patterns of energy flow in ecosystems. - Provides fresh ways of describing food webs and applies previous observations in a new context - Ranked as the #1 publication in the Institute for Scientific Information in the Ecology section of 2000 - Powerful new theory AND application to some of the best food web data in the world - Many mathematical models for food web structure and function - Integrates previously unconnected perspectives on the description of ecological communities
Experimentation is a dominant approach in contemporary ecological research, pervading studies at all levels of biological organization and across diverse taxa and habitats. Experimental Ecology assembles an eminent group of ecologists who synthesize insights from these varied sources into a cogent statement about experimentalism as an analytical paradigm, placing experimentation within the larger framework of ecological investigation. The book discusses diverse experimental approaches ranging from laboratory microcosms to manipulation of entire ecosystem, illustrating the myriad ways experiments strengthen ecological inference. Experimental ecologists critique their science to move the field forward on all fronts: from better designs, to better links between experiments and theory, to more realism in experiments targeted at specific systems and questions.
The assessment of the ecological integrity of running waters is a prerequisite to an understanding of the effects of human alterations. The evaluation of degradation processes provides key information on how to avoid further negative impacts. The success of future conservation, mitigation and restoration activities will rely on sound assessment methodologies and their ecological relevance and applicability. Assessment methodologies are therefore an integral part of sustainable river management. This book synthesizes and discusses state-of-the-art experiences in assessment methodologies. Including the latest knowledge on structures, processes and functions of running waters as a fundamental basis for developing adequate assessment methods, the book focuses on method development, application, and in particular on integrated assessment methods. This book is directed at scientists and managers with the aim of more effective preservation, restoration and maintenance of the ecological integrity of running water ecosystems.
Inland saline waters are threatened worldwide by diversion and pollution of their inflows, introductions of exotic species and economic development of these ecologically valuable habitats. Since 1979 a series of international symposia on inland saline waters has served to strengthen and expand the scope of limnological research on inland saline waters. The seventh conference continued this tradition and the papers derived from the conference focused on the ecology of microbial communities, the influence of habitat geochemistry on biogeography of flora and fauna, physical and geochemical processes, and the conservation of inland saline waters. Of particular note are papers on Walker Lake, Nevada (USA), and the Salton Sea and Mono Lake, California (USA). Continued local, national and international efforts are required to inform the public and decision-makers about the environmental problems faced by saline waters. The papers in this volume will serve this end and should be of interest to aquatic ecologists, limnologists, aquaculturalists, and water resource managers.
