Download or read book Thermoregulating Ability and Minimum Flight Temperature in Interior Alaska Dragonflies Odonata Anisoptera written by Todd Sformo and published by . This book was released on 2003 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The use of operative environmental temperature (Te) has been a major advance in the study of thermal ecology. I review the use of operative temperature in thermal biology with an emphasis on insects. Then I use data from dragonflies in Interior Alaska (Odonata: Anisoptera) to compare the efficacy of operative and ambient temperature when examining thermoregulating ability. I conclude that although the use of Te may provide more accurate measures of thermoregulation under specific environmental conditions, the use of ambient temperature usually leads to the same conclusions about thermoregulating ability. I next examine the relationships between thermoregulating ability, minimum flight temperature (MFT), mass, passive cooling rate, and wing loading for the ten species of dragonflies present in Interior Alaska investigate the influence of ambient temperature and solar radiation on daily and seasonal activity patterns. I find a range of thermoregulating abilities from complete thermoconformers to very efficient periodic thermoregulators. The ability to thermoregulate is strongly tied to body mass. Thermoconfomers have significantly lower MFTs than thermoregulators, suggesting a possible tradeoff between the ability to operate and low and high thoracic temperatures"--Leaf 3.

Available in PDF, EPUB and Kindle. Book excerpt: Dragonflies and damselflies (together known as Odonata) are among the most remarkably distinctive insects in their appearance and biology, and they have become some of the most popular creatures sought by avocational naturalists. Texas hosts 160 species of dragonflies, nearly half of the 327 species known in North America, making the state a particularly good place to observe dragonflies in their natural habitats. Dragonflies of Texas is the definitive field guide to these insects. It covers all 160 species with in situ photographs and detailed anatomical images as needed. Each species is given a two-page spread that includes photographs of both sexes and known variations when possible, key features, a distribution map, identification, discussion of similar species, status in Texas, habitat, seasonality, and general comments. Many of the groups also have comparative plates that show anatomically distinctive characteristics. In addition to the species accounts, John Abbott discusses dragonfly anatomy, life history, conservation, names, and photography. He also provides information on species that may eventually be discovered in Texas, state and global conservation rankings, seasonality of all species in chronological order, and additional resources and publications on the identification of dragonflies.

Download or read book Dragonfly Notes written by Anne Panning and published by . This book was released on 2018-09-18 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: When a seemingly routine medical procedure results in her mother's premature death, Anne Panning is left reeling. In her first full-length memoir, the celebrated essayist and short story writer draws on decades of memory and experience, piecing together hard truths about her own past and her mother's. We follow Panning's winding path from rural Minnesota to the riverbanks of Vietnam's Mekong Delta. A stark, poignant tale of two women deeply connected, yet forever apart, Dragonfly Notes is a testament to the prevailing nature of love, whether in the form of a rediscovered note, a sudden moment of unexpected recall, or sometimes, simply, the sight a dragonfly flitting past.
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.
