Limnology, stream ecology, and wetland ecology all share an interdisciplinary perspective of inland aquatic habitats. Scientists working in these fields explore the roles of geographic position, physical and chemical properties, and the other biota on the different kinds of plants and animals living in freshwaters. How do these creatures interact with each other and with their physical environment? In what ways have humans impacted aquatic habitats? By what methods do freshwater ecologists study these environments? With this new laboratory manual, Havel provides a variety of accessible hands-on exercises to illuminate key concepts in freshwater ecology. These exercises include a mixture of field trips, indoor laboratory exercises, and experiments, with some portions involving qualitative observations and others more quantitative. With the help of this manual, students will develop an appreciation for careful techniques used in the laboratory and in the field, as well as an understanding of how to collect accurate field notes, keep a well-organized lab notebook, and write clear scientific reports.

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 practical manual of freshwater ecology and conservation provides a state-of-the-art review of the approaches and techniques used to measure, monitor, and conserve freshwater ecosystems. It offers a single, comprehensive, and accessible synthesis of the vast amount of literature for freshwater ecology and conservation that is currently dispersed in manuals, toolkits, journals, handbooks, 'grey' literature, and websites. Successful conservation outcomes are ultimately built on a sound ecological framework in which every species must be assessed and understood at the individual, community, catchment and landscape level of interaction. For example, freshwater ecologists need to understand hydrochemical storages and fluxes, the physical systems influencing freshwaters at the catchment and landscape scale, and the spatial and temporal processes that maintain species assemblages and their dynamics. A thorough understanding of all these varied processes, and the techniques for studying them, is essential for the effective conservation and management of 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.
