This book was released on 1996-12-15 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caddisflies are one of the most diverse groups of organisms living in freshwater habitats, and their larvae are involved in energy transfer at several levels within these communities. Caddisfly larvae are also remarkable because of the exquisite food-catching nets and portable cases they construct with silk and selected pieces of plant and rock materials. This book is the most comprehensive existing reference on the aquatic larval stages of the 149 Nearctic genera of Trichoptera, comprising more than 1400 species in North America. The book is invaluable for freshwater biologists and ecologists in identifying caddisfly in the communities they study, for students of aquatic biology as a guide to the diverse fauna of freshwater habitats, and for systematic entomologists as an atlas of the larval morphology of Trichoptera. In the General Section, the biology of caddisfly larvae is considered from an evolutionary point of view. Morphological terms are discussed and illustrated and a classification of the Nearctic genera is given. Techniques are outlined for collecting and preserving larval specimens and for associating larval with adult stages. The Systematic Section begins with a key to larvae of the 26 families of North American Trichoptera. Each chapter in this section is devoted to a particular family, providing a summary of biological features and a key to genera, followed by a two-page outline for each genus with illustrations facing text. This outline provides information on general distribution, number of species, distinctive morphological features, and biological data including construction behaviour. An important feature of the book is the habit illustrations of larvae and cases of a selected species in each genus, along with illustrations of details of significant morphological structures. Each generic type is thus presented as a recognizable whole organism adapted in elegant ways to particular niches of freshwater communities. This revised edition includes advances in knowledge on the classification and biology of Trichoptera up to 1993 - an interval of 17 years since the first edition. An additional eight families and thirteen genera are included for the first time. Through reorganization of the families into three suborders, a biological context has been established for the systematic section.

Download or read book Biological diversity of the Minnesota caddisflies Insecta Trichoptera written by David C. Houghton and published by PenSoft Publishers LTD. This book was released on 2012-07-24 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contains illustrations, statewide abundances, distributions, adult flight periodicities, and habitat affinities for all of the 277 known Minnesota caddisfly species. Many species, especially within the long-lived shredder families Limnephilidae and Phryganeidae, have decreased in distribution and abundance during the past 75 years, particularly those once common within the Northwestern and Southern regions. Many species now appear regionally extirpated, and a few have disappeared from the entire state. This loss of species in the Northwestern and Southern regions, and probably elsewhere, is almost certainly relatd to the conversion of many habitats to large-scale agriculture during the mid-20th century. With baseline data now in place, any future changes to the Minnesota caddisfly fauna can be evaluated with much greater confidence and precision.

Download or read book Caddisflies written by Glenn B. Wiggins and published by University of Toronto Press. This book was released on 2005-12-15 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Caddisflies constitute the insect order Trichoptera in which some 10,000 species are known in the world, including about 1400 in North America. Fossil evidence shows that caddisflies originated in the Triassic period, 200-250 million years ago. They are important links in the movement of energy and nutrients through freshwater ecosystems due largely to the extraordinary diversification in their larval architecture, which includes portable and stationary shelters, silken filter nets, and osmotically semipermeable cocoons. Glenn Wiggins's Caddisflies is the foremost comprehensive reference source about these insects and is concerned with behavioural ecology, evolutionary history, biogeography, and biological diversity. Wiggins outlines fundamental concepts of aquatic ecology, illuminating the ways in which caddisflies help to make fresh waters work. Essential features of morphology, biology, and distribution are outlined for the twenty-six North American families of caddisflies and illustrated diagnostic keys are provided for larvae, pupae, and adults. The author also brings together information on caddisflies from widely scattered sources and provides comprehensive coverage of the scientific literature.
