Dragonflies and Damselflies of the West
Author: Dennis PaulsonPublisher: Princeton University Press
ISBN: 0691122814
Category : Nature
Languages : en
Pages : 537
Book Description
Dragonflies and Damselflies of the West is the first fully illustrated field guide to all 348 species of dragonflies and damselflies in western North America. Dragonflies and damselflies are large, stunningly beautiful insects, as readily observable as birds and butterflies. This unique guide makes identifying them easy--its compact size and user-friendly design make it the only guide you need in the field. Every species is generously illustrated with full-color photographs and a distribution map, and structural features are illustrated where they aid in-hand identification. Detailed species accounts include information on size, distribution, flight season, similar species, habitat, and natural history. Dennis Paulson's introduction provides an essential primer on the biology, natural history, and conservation of these important and fascinating insects, along with helpful tips on how to observe and photograph them. Dragonflies and Damselflies of the West is the field guide naturalists, conservationists, and dragonfly enthusiasts have been waiting for. Covers all 348 western species in detail Features a wealth of color photographs Provides a color distribution map for every species Includes helpful identification tips Serves as an essential introduction to dragonflies and their natural history

Thermoregulating Ability and Minimum Flight Temperature in Interior Alaska Dragonflies (Odonata: Anisoptera)
Author: Todd SformoPublisher:
ISBN:
Category : Body temperature
Languages : en
Pages : 184
Book Description
"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.
