Book Synopsis Dragonfly Nymphs of North America by : Kenneth J. Tennessen
Download or read book Dragonfly Nymphs of North America written by Kenneth J. Tennessen and published by Springer. This book was released on 2019-03-11 with total page 627 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is the first of its kind devoted entirely to the dragonfly nymphs of North America north of Mexico, the focus being accurate identification of the 330 species of Anisoptera that occur in the region. Nymphal external morphology is described and illustrated in detail, and all terms needed to navigate the dichotomous keys are defined. Species are tabulated with references that provide the most detailed, accurate descriptions for each; species that are inadequately described are so indicated. The key separating the seven families in the region contains several new characters. The families are then covered separately: Aeshnidae (13 genera), Gomphidae (17 genera), Petaluridae (2 genera), Cordulegastridae (2 genera), Macromiidae (2 genera), Corduliidae (7 genera), and Libellulidae (29 genera). Each family is further characterized, followed by a generic key. A drawing of the habitus and diagnostic details for each genus are provided, along with additional diagnostic remarks and notes on habitat and life cycle; for each genus, a map shows its geographic distribution in North America. Full-grown nymphs of all known species of each genus are keyed and diagnosed; characters that apply to earlier instars are noted. Morphological variation in character states was analyzed in order to assess the reliability of previously utilized characters and to discover new characters. Most of the characters used to distinguish all levels of taxa are illustrated; a total of 702 figures, comprising 1,800 original drawings, along with selected photographs where necessary for clarity, accompany the keys. Measurements of total length, head width, and other variables for each species are provided in tables. Difficulties with past keys and descriptions, including errors, omissions and other shortcomings, are addressed. The importance of nymph characters in helping solve generic and specific distinctions and their role in phylogenetic studies is emphasized. Methods for collecting, rearing, and preserving dragonfly nymphs and exuviae are presented. The final chapter discusses research opportunities on North American Anisoptera nymphs, including taxonomic needs, studies on structure and function, life history and microhabitat, water quality indices and conservation efforts. The habitus drawings of all genera are arranged according to family in five plates (Appendix I); although the book is intended as a lab manual, these plates conveniently allow for comparison based on nymph shape making field identification to genus possible in many cases. Appendix II contains a brief history of dragonfly nymph studies in North America. A glossary and an index to scientific names are included.

Book Synopsis Dragonflies at a Biogeographical Crossroads by : Brenda D. Smith
Download or read book Dragonflies at a Biogeographical Crossroads written by Brenda D. Smith and published by CRC Press. This book was released on 2020-11-11 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: This lavishly illustrated book examines the distribution, ecology, conservation status, and biogeography of 176 species of dragonflies in the southern plains of the United States, where twelve ecoregions converge. The topics discussed, such as phenotypic variation and ecology, are applicable and of interest across the United States and much of north America, and will appeal to researchers and dragonfly enthusiasts alike. A series of maps, including a distributional map by specific locality of occurrence, indicate level of documentation and allow the reader to visualize the biogeographical associations of a given species. These maps also encourage citizen scientists to contribute documentation wherever they spend time in the field. Context-driven chapters, including one on the region’s rich paleontological history, blend environmental history and biogeography, giving the book a fresh perspective on the natural world while providing a rich summary of the odonates. Dragonflies at a Biographical Crossroads: The Odonata of Oklahoma and Complexities Beyond Its Borders will be sought out by dragonfly researchers and enthusiasts, entomologists, amateur naturalists, paleontologists, conservation biologists, educators, regional historians, and those seeking to meld the disciplines of cultural and environmental history with biology. It will also be readily accessible to the lay public. Dragonflies combine the visually stunning with acrobatic fireworks in ways no other insect can hope to combine.
