Freshwater Ostracods

Their story began 500 million years ago, but we only started to get to know them in 1746, when Linné described the first ostracod species. Vividly portraying the freshwater ostracods, this comprehensive reference work gathers the knowledge gained during some 250 years, but which to date has remained scattered throughout the literature. It starts with an introduction to the class Ostracoda with a special focus on freshwater ostracods and highlights practical methods in their study. The systematic part includes an introduction to all families; identification keys for all subfamilies, genera and species; diagnoses for each subfamily and genus; and lists of synonyms and distribution of species. The text is richly illustrated with distribution maps, line drawings of key generic characteristics, and numerous SEM photographs. Serving as an excellent starting point for all further research on freshwater ostracods, it can be widely used not only by ostracodologists, but also by crustaceologists, evolutionists and ecologists.

Need-to-know information on the classification and identificationof aquatic invertebrates This Fourth Edition of the standard reference used by generationsof professionals and students is the source for authoritativeinformation on the natural history, ecology, and taxonomy offree-living American freshwater invertebrates. Completely revisedand updated, this professional field guide features a wealth of newknowledge on invertebrate animal phyla covered in the previousedition as well as fully modified sections on the preparation ofmaterials. Other important features of Pennak's Freshwater Invertebrates ofthe United States, Fourth Edition include: * Current taxonomical arrangements of all freshwater invertebrateanimals, excluding insects * Improved graphical treatments and keys to identification, severalprovided by specialists * Photographs and color plates to aid identification * More than 300 line drawings, many new to this edition * Taxonomic keys carried uniformly to genus level in all but twophyla, with frequent references to species Pennak's Freshwater Invertebrates of the United States, FourthEdition is an indispensable resource for biologists, ecologists,graduate students, and anyone who needs to acquire the thoroughknowledge of aquatic invertebrates that is essential tounderstanding the community structure of freshwater environments.

Thorp and Covich's Freshwater Invertebrates: Keys to Nearctic Fauna, Fourth Edition presents a comprehensive revision and expansion of this trusted professional reference manual and educational textbook-from a single North American tome into a developing multivolume series covering inland water invertebrates of the world. Readers familiar with the first three editions will welcome this new volume. The series, now entitled Thorp and Covich’s Freshwater Invertebrates, (edited by J.H. Thorp), began with Volume I: Ecology and General Biology, (edited by J.H. Thorp and D.C. Rogers). It now continues in Volume II with taxonomic coverage of inland water invertebrates of the Nearctic zoogeographic region. As in previous editions, all volumes of the fourth edition are designed for multiple uses and levels of expertise by professionals in universities, government agencies, and private companies, as well as by undergraduate and graduate students. Features zoogeographic coverage for all of North America, south to the general area of the Tropic of Cancer, and Greenland and Bermuda Provides keys to families of freshwater insects Provides keys to all other inland water invertebrates at the taxonomic level appropriate for the current scientific knowledge Includes multiple taxonomic keys in each chapter that progress from higher to lower taxonomic levels, thereby allowing users to work up to their level of need and expertise Presents additional material in each chapter on group introduction, limitations to the keys, terminology and morphology, material preparation and preservation, and references

Identification and Ecology of Freshwater Arthropods in the Mediterranean Basin covers the entire Mediterranean basin, including parts of Europe, Asia, Africa and the Mediterranean islands, but excluding other biogeographic locations with Mediterranean climates located outside the region. The book provides an extensive description of the taxonomy and ecology of aquatic arthropods encountered in lentic and lotic habitats, as well as in less studied underground and estuarine habitats. It offers expanded taxonomic identification keys to major groups of arthropods with a description of their ecology and distribution. Keys for insects include aquatic larval stages and water-dwelling adults of Coleoptera and Heteroptera. Additional sections focus on taxa that can be encountered in adjacent brackish and estuary ecosystems as long as the taxon primarily occurs in freshwaters. This is a much-needed, comprehensive resource on the taxonomy and ecology of freshwater arthropods with an introduction to recent molecular tools for identifications. It will be particularly useful for freshwater ecologists, limnologists, environmentalists and students in the ecological sciences. Presents taxonomic keys to genera and species to the majority of aquatic arthropod families Provides coverage of all freshwater ecosystems of the Mediterranean basin, with case studies and examples Includes numerous photographs of the aquatic arthropods described in the chapters Covers the ecology and taxonomy of organisms living in more traditionally studied lakes and streams as well as in less studied underground and estuarine habitats

The First Edition of Ecology and Classification of North American Freshwater Invertebrates has been immensely popular with students and researchers interested in freshwater biology and ecology, limnology, environmental science, invertebrate zoology, and related fields. The First Edition has been widely used as a textbook and this Second Edition should continue to serve students in advanced classes. The Second Edition features expanded and updated chapters, especially with respect to the cited references and the classification of North American freshwater invertebrates. New chapters or substantially revised chapters include those on freshwater ecosystems, snails, aquatic spiders, aquatic insects, and crustaceans. Most up-to-date and informative text of its kind Written by experts in the ecology of various invertebrate groups, coverage emphasizes ecological information within a current taxonomic framework Each chapter contains both morphological and taxonomic information, including keys to North American taxa (usually to the generic level) as well as bibliographic information and a list of further readings The text is geared toward researchers and advanced undergraduate and graduate students
