Snakeheads Pisces Channidae

An updated key to the seven species is presented. The ecology of the species is detailed and the importance of conserving their habitats emphasised. Emphasis is placed on poorly known stenotopic forest species whose habitats are fast disappearing. The taxonomy of several problematic species from Borneo and Sumatra is also briefly discussed. [Authors' abstract].

This title explores the role of snakehead fish in introduced environments, how humans helped spread the species, the threats they pose to ecosystems, and efforts being taken to manage them. This book also includes a table of contents, two infographics, informative sidebars, a “That’s Amazing!” special feature, quiz questions, a glossary, additional resources, and an index. This Focus Readers title is at the Navigator level, aligned to reading levels of grades 3–5 and interest levels of grades 4–7.

"Of all the literature I use while preparing field guides for the Food and Agriculture Organization of the United Nations, Nelson's Fishes of the World is, by far, the one I refer to most often. [This] book is a standard reference . . . I continue to use it extensively in the ichthyology courses I teach, particularly in laboratory sessions." -Kent E. Carpenter Old Dominion University "Fishes of the World is a unique and essential resource for anyone seriously interested in the diversity and evolution of fishes. The family accounts provide quick summaries of current knowledge on all groups of living fishes and many key fossil taxa. It is a required work for every student in my laboratory." -William E. Bemis Kingsbury Director of Shoals Marine Laboratory, Cornell University "Only classics are known by the single name of their author, and certainly [Nelson's book] has for four editions been such a book for all those who seek an accessible, up-to-date, readable reference on fish classification. Once again, Nelson presents a balanced view of the sometimes tumultuous, but ever-exciting, study of the phylogenetic relationships and classification of fishes. In doing so, Nelson makes an excellent case for organismal biology, highlighting the many and varied morphological characters we use to diagnose fish taxa and differentiate among the 515 families of living species." -Lynne R. Parenti Curator of Fishes and Research Scientist, National Museum of Natural History, Smithsonian Institution Fishes of the World, Fourth Edition is the updated edition of a true classic in the field. A unique presentation of a modern, cladistically based classification of all the major living and fossil fish groups, this indispensable reference helps scientists and others identify and classify specimens, make familial connections, understand the evolution of fishes, and springboard into further research. The taxonomy of fishes presented includes the anatomical characteristics, distribution, common and scientific names, and phylogenetic relationships for all 515 families of living fishes. Packed with representative species drawings and information on phylogentic relationships, this informative Fourth Edition features: * Both fossil and extant species * More than 500 illustrations * Fully vetted scientific and common names * An extensive bibliography

With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.

'The Biology of Temporary Waters' brings together diverse global literature on pure and applied aspects of temporary waters and their biotas. It examines their roles in both natural and human environments and seeks common evolutionary themes.
