Popular interest in the observation and study of freshwater invertebrates is increasing. This book meets the needs of this growing audience of naturalists, environmentalists, anglers, teachers, students, and others by providing substantive information in easy-to-understand, non-technical language for many groups of invertebrates commonly found in the streams, lakes, ponds, and other freshwater environments of North America. Section One provides background information on the biology and ecology of freshwater organisms and environments and explains why and how invertebrates can be studied, simply and without complex equipment, in the field and the laboratory. Section Two describes nearly 100 of the most common groups of invertebrates, and for each group a whole-body colour illustration is provided along with brief text pointing out the most important features that identify members of the group. Section Three contains in-depth descriptions of the life history, behaviour, and ecology of the various invertebrate groups, and explains their important ecological contributions and relationships to humans. The Guide is broad in scope, geographically and taxonomically, and it is written at a substantive yet easily accessible level that will appeal to both novices and those with more advanced knowledge of the subject. It also contains more than 100 specially commissioned colour illustrations by the well-known scientific illustrator Amy Bartlett Wright that will greatly facilitate the easy and rapid identification of specimens.

The Field Guide to Freshwater Invertebrates of North America focuses on freshwater invertebrates that can be identified using at most an inexpensive magnifying glass. This Guide will be useful for experienced nature enthusiasts, students doing aquatic field projects, and anglers looking for the best fish bait, lure, or fly. Color photographs and art, as well as the broad geographic coverage, set this guide apart. 362 color photographs and detailed descriptions aid in the identification of species Introductory chapters instruct the reader on how to use the book, different inland water habitats and basic ecological relationships of freshwater invertebrates Broad taxonomic coverage is more comprehensive than any guide currently available

"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.

A guide to the identification of insects and other macroinvertebrates found in bodies of freshwater in northeastern North America. Essentially a collection of regional taxonomic keys, it covers the aquatic and semiaquatic life stages of insects as well as freshwater crustaceans, mites, mollusks, oligochaetes, and leeches. Each chapter begins with a brief natural history of the taxon and a discussion of collection and preservation techniques. Following is a checklist of the families and genera, or in the noninsect chapters higher taxa, of the animals included in the key. Most of the chapter is devoted to the key: a series of concise couplets, well illustrated with many diagnostic drawings. Annotation copyrighted by Book News, Inc., Portland, OR

Fully illustrated guide to identifying water-dwelling macroinvertebrates. A handy resource for anglers, students, biologists, or anyone else spending time near rivers and streams. Gives tips for distinguishing similar species and includes information for each species on behavior and role played in the ecosystem.

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.
