Available in PDF, EPUB and Kindle. Book excerpt: The essential guide for identifying the bumble bees of North America More than ever before, there is widespread interest in studying bumble bees and the critical role they play in our ecosystems. Bumble Bees of North America is the first comprehensive guide to North American bumble bees to be published in more than a century. Richly illustrated with color photographs, diagrams, range maps, and graphs of seasonal activity patterns, this guide allows amateur and professional naturalists to identify all 46 bumble bee species found north of Mexico and to understand their ecology and changing geographic distributions. The book draws on the latest molecular research, shows the enormous color variation within species, and guides readers through the many confusing convergences between species. It draws on a large repository of data from museum collections and presents state-of-the-art results on evolutionary relationships, distributions, and ecological roles. Illustrated keys allow identification of color morphs and social castes. A landmark publication, Bumble Bees of North America sets the standard for guides and the study of these important insects. The best guide yet to the 46 recognized bumble bee species in North America north of Mexico Up-to-date taxonomy includes previously unpublished results Detailed distribution maps Extensive keys identify the many color patterns of species

Book Synopsis The Natural History of Bumblebees by : Carol Ann Kearns
Download or read book The Natural History of Bumblebees written by Carol Ann Kearns and published by Boulder Colo. : University Press of Colorado. This book was released on 2001 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In The Natural History of Bumblebees, biologists Carol A. Kearns and James D. Thomson give amateurs and professionals alike the basic knowledge to pursue the joys of observing and investigating these attractive and amenable subjects. Packed with information on bumblebee colonies, bee honeypots, bee development, foraging behavior, as well as instructions for maintaining bumblebees in captivity, this lively and colorful book also includes an easy-to-use photographic field guide to aid in the identification of over fifty species of North American bumblebee-virtually every known species on this continent. Until now, even the basic identification of North American bumblebees has been through the use of highly technical regional keys. The Natural History of Bumblebees fills a gap in the literature and provides amateur enthusiasts, educators, and scholars the information to develop their own projects in bumblebee biology. Kearns and Thomson also provide detailed instructions for constructing simple equipment that facilitates bee wrangling: the handling, tagging, studying, and raising of bumblebees. They present suggestions for research projects and identify areas of incomplete knowledge requiring further research. This book is an invaluable reference for students and scholars of native pollinators and an indispensable resource for naturalists, gardeners, and anyone who has ever been fascinated by the flight of the bumblebee.

Book Synopsis Natural Enemies of Native Bumble Bees (Hymenoptera: Apidae) in Western Oregon by : Sarah A. Maxfield-Taylor

This book was released on 2014 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bumble bees (Hymenoptera: Apidae) are important native pollinators in wild and agricultural systems, and are one of the few groups of native bees commercially bred for use in the pollination of a range of crops. In recent years, declines in bumble bees have been reported globally. One factor implicated in these declines, believed to affect bumble bee colonies in the wild and during rearing, is natural enemies. A diversity of fungi, protozoa, nematodes, and parasitoids has been reported to affect bumble bees, to varying extents, in different parts of the world. In contrast to reports of decline elsewhere, bumble bees have been thriving in Oregon on the West Coast of the U.S.A. In particular, the agriculturally rich Willamette Valley in the western part of the state appears to be fostering several species. Little is known, however, about the natural enemies of bumble bees in this region. The objectives of this thesis were to: (1) identify pathogens and parasites in (a) bumble bees from the wild, and (b) bumble bees reared in captivity and (2) examine the effects of disease on bee hosts. Bumble bee queens and workers were collected from diverse locations in the Willamette Valley, in spring and summer. Bombus mixtus, Bombus nevadensis, and Bombus vosnesenskii collected from the wild were dissected and examined for pathogens and parasites, and these organisms were identified using morphological and molecular characteristics. Queens of Bombus griseocollis, Bombus nevadensis, and Bombus vosnesenskii were reared in captivity, and those that died or did not initiate nests were also examined for pathogens and parasites. In addition, the immune responses of healthy and infected bees were compared, to examine the effects of a common bumble bee gut pathogen Crithidia bombi (Kinetoplastida: Trypanosomatidae) on its host. This thesis reports that wild bumble bees in western Oregon are infected with the protozoa Apicystis bombi (Neogregarinida: Ophrocystidae) and Crithidia bombi, the fungus/microsporidian Nosema bombi (Microsporidia: Nosematidae), the nematode Sphaerularia bombi (Nematoda: Tylenchida), and two dipteran parasitoids, one unknown and one belonging to the family Conopidae (Diptera: Conopidae). In addition, this research presents the first ever report of infection by the larval pathogen Ascosphaera apis (Ascomycota: Ascosphaerales), in reared bumble bee adults. New host and distribution records are also presented for C. bombi, N. bombi, and S. bombi. The study found that bumble bees infected with C. bombi had lower activated levels of immune responses than healthy bees. The thesis discusses the long-term implications of study findings, and addresses the threat that bumble bee diseases pose to bee pollinators through shared environments.
