Aquatic Ecology A Study Of Marine And Freshwater Ecosystems

Fundamentals of Aquatic Ecology is a completely updated and revised edition of the earlier work, Fundamentals of Aquatic Ecosystems. The new edition has been re-titled to reflect the fact that the authors found that, from the modification exercise, a completely different and new book emerged. The new edition concentrates heavily of the fundamental features common to all aquatic systems, both marine and freshwater. This unique synthesis allows for the discussion of ecological processes comparatively, across environments. A general introduction is followed by discussion of various 'types' of aquatic ecosystems - open waters, coastal zones, benthos, and the aquatic ecosystem as a whole. This is followed by an important new chapter on aquatic ecosystems and global ecology. Later chapters consider the individuals and communities in aquatic ecosystems. A totally re-written and rejuvenated edition of an established student text. Synthesizes both marine and freshwater ecology. Covers both ecosystem ecology and population biology. In depth consideration of man's impact on the aquatic environment.

Freshwater ecosystems are under increasing pressure as human populations grow and the need for clean water intensifies. The demand for ecologists and environmental managers who are trained in basic freshwater ecology has never been greater. Students and practitioners new to the field of freshwater ecology and management need a text that provides them with an accessible introduction to the key questions while still providing sufficient background on basic scientific methods. Gerry Closs, Barbara Downes and Andrew Boulton have written a text that meets the requirements of these students. Following an introduction to scientific methodology and its application to the study of ecology, several key concepts in freshwater ecology are reviewed using a wide range of scientific studies into fundamental and applied ecological questions. Key ecological questions that are explored in a freshwater context include the role of animal dispersal and predators on freshwater community structure and the impact of pollutants and introduced species on freshwater ecosystems. This book represents the only freshwater ecology textbook that is specifically aimed at an introductory level. It will also be a useful primer for students who have not previously taken a specialized freshwater course but who require an accessible overview of the subject. General reviews on the methods of science, influence of scale, and the main features of freshwater systems. Coverage of several fundamental and applied ecological questions. A logical structure in each chapter that builds from a general observation of an ecological pattern, to an exploration of the various scientific approaches that can be used to investigate such patterns. Suggested further reading lists for each chapter.

This book explores current exploitation practices, and the ecological basis and consequences of that exploitation.

The study of aquatic ecosystems and the organisms that inhabit them are studied in the two fields of aquatic ecology and biology. An aquatic ecosystem is a combination of various biotic communities and abiotic factors. Abiotic factors include parameters of water depth, nutrient level, salinity, temperature, etc. Maintenance of normal values of these variables is essential for the continued sustainability of the diverse flora and fauna of such ecosystems. Aquatic ecosystems are primarily grouped into marine and freshwater ecosystems, along with lentic, pond, lotic and wetlands forming other smaller classes. Aquatic ecosystems are crucial for the efficient recycling of nutrients, purification of water, ground water replenishment and in the provision of habitats to aquatic life. This book provides significant information on these disciplines to help develop a good understanding of aquatic biology and ecology and their related fields. It also includes some of the vital pieces of work being conducted across the world. This book is a vital tool for all researching or studying aquatic sciences as it gives incredible insights into the emerging trends and concepts

Freshwater Ecology, Second Edition, is a broad, up-to-date treatment of everything from the basic chemical and physical properties of water to advanced unifying concepts of the community ecology and ecosystem relationships as found in continental waters. With 40% new and expanded coverage, this text covers applied and basic aspects of limnology, now with more emphasis on wetlands and reservoirs than in the previous edition. It features 80 new and updated figures, including a section of color plates, and 500 new and updated references. The authors take a synthetic approach to ecological problems, teaching students how to handle the challenges faced by contemporary aquatic scientists. This text is designed for undergraduate students taking courses in Freshwater Ecology and Limnology; and introductory graduate students taking courses in Freshwater Ecology and Limnology. Expanded revision of Dodds' successful text. New boxed sections provide more advanced material within the introductory, modular format of the first edition. Basic scientific concepts and environmental applications featured throughout. Added coverage of climate change, ecosystem function, hypertrophic habitats and secondary production. Expanded coverage of physical limnology, groundwater and wetland habitats. Expanded coverage of the toxic effects of pharmaceuticals and endocrine disrupters as freshwater pollutants More on aquatic invertebrates, with more images and pictures of a broader range of organisms Expanded coverage of the functional roles of filterer feeding, scraping, and shredding organisms, and a new section on omnivores. Expanded appendix on standard statistical techniques. Supporting website with figures and tables - http://www.elsevierdirect.com/companion.jsp?ISBN=9780123747242

The branch of ecology which studies the interactions between various organisms which dwell in water bodies, and their surroundings, is known as aquatic ecology. The different aquatic environments which fall under the domain of aquatic ecology are estuaries, lakes, ponds, oceans and rivers. An ecosystem which exists in a body of water is known as an aquatic ecosystem. There are primarily two types of aquatic ecosystems, marine and freshwater ecosystems. Marine ecosystems are further divided into various zones like oceanic zone, benthic zone and intertidal zone. Freshwater ecosystems are broadly divided into three types - lentic, lotic and wetlands. Lentic ecosystems are made up of slow moving water. Lotic ecosystems consist of faster moving water, such as streams and rivers. Wetlands are ecosystems which are flooded by water, either seasonally or permanently. This book provides comprehensive insights into the field of aquatic ecology. The topics included herein on this subject are of utmost significance and bound to provide incredible insights to readers. Those in search of information to further their knowledge will be greatly assisted by this book.

All the water bodies on Earth have an aquatic ecosystem and an aquatic ecology. It consists of all the under-water plants, animals, etc. Aquatic ecology can be divided into two main parts namely freshwater ecosystem and marine ecosystem. This book is a valuable compilation of topics, ranging from the basic to the most complex discoveries and principles in the field of aquatic ecology. The topics included in it are of utmost significance and bound to provide incredible insights to readers. Those with an interest in the subject of aquatic ecology would find this textbook helpful.
