This book describes the main features of tropical streams and their ecology. It covers the major physico-chemical features, important processes such as primary production and organic-matter transformation, as well as the main groups of consumers: invertebrates, fishes and other vertebrates. Information on concepts and paradigms developed in north-temperate latitudes and how they do not match the reality of ecosystems further south is expertly addressed. The pressing matter of conservation of tropical streams and their biodiversity is included in alomost every chapter, with a final chapter providing a synthesis on conservation issues. For the first time, Tropical Streams Ecology places an important emphasis on viewing research carried out in contributions from international literature. * First synthetic account of the ecology of all types of tropical streams * Covers all of the major tropical regions * Detailed consideration of possible fundamental differences between tropical and temperate stream ecosystems * Threats faced by tropical stream ecosystems and possible conservation actions * Descriptions and synstheses life-histories and breeding patterns of major aquatic consumers (fishes, invertebrates)

Methods in Stream Ecology provides a complete series of field and laboratory protocols in stream ecology that are ideal for teaching or conducting research. This two part new edition is updated to reflect recent advances in the technology associated with ecological assessment of streams, including remote sensing. Volume focusses on ecosystem structure with in-depth sections on Physical Processes, Material Storage and Transport and Stream Biota. With a student-friendly price, this Third Editionis key for all students and researchers in stream and freshwater ecology, freshwater biology, marine ecology, and river ecology. This text is also supportive as a supplementary text for courses in watershed ecology/science, hydrology, fluvial geomorphology, and landscape ecology.Provides a variety of exercises in each chapterIncludes detailed instructions, illustrations, formulae, and data sheets for in-field research for studentsPresents taxonomic keys to common stream invertebrates and algaeIncludes website with tables and a link from Chapter 22: FISH COMMUNITY COMPOSITION to an interactive program for assessing and modeling fish numbersWritten by leading experts in stream ecology
