Thresholds of Response in Nest Thermoregulation by Worker Bumble Bees, Bombus Bifarius Nearcticus (Hymenoptera: Apidae)

Foster O'Donnell, S. & Foster, R. L. 2001: Thresholds of response in nest thermoregulation by worker bumble bees, Bombus bifarius nearcticus (Hymenoptera: Apidae). Ethology 107, 387Ð399. Abstract Regulation of nest temperature is important to the ®tness of eusocial insect colonies. To maintain appropriate conditions for the developing brood, workers must exhibit thermoregulatory responses to ambient temperature. Because nest- mate workers dier in task performance, thermoregulatory behavior provides an opportunity to test threshold of response models for the regulation of division of labor. We found that worker bumble bees (Bombus bifarius nearcticus) responded to changes in ambient temperature by altering their rates of performing two tasks ± wing fanning and brood cell incubation. At the colony level, the rate of incubating decreased, and the rate of fanning increased, with increasing temperature. Changes in the number of workers performing these tasks were more important to the colony response than changes in workers' task perform- ance rates. At the individual level, workers' lifetime rates of incubation and fanning were positively correlated, and most individuals did not specialize exclusively on either of these temperature-sensitive tasks. However, workers diered in the maximum temperature at which they incubated and in the minimum temperature at which they fanned. More individuals fanned at high and incubated at low temperatures. -
Bumble Bees of the Western United States” by Jonathan Koch, James Strange, and Paul Williams (2012)
Adapted from the “Bumble Bees of the Western United States” by Jonathan Koch, James Strange, and Paul Williams (2012). Bumble bees are one of Wyoming’s most important and mild-mannered pollinators. There are more than 20 species in Wyoming, which you can often tell apart by the color patterns on their bodies. This guide shows color patterns for queen bees only, and some species can have multiple queen Bumble patterns! of Bees Areas in yellow indicate where each species Wyoming is found in Wyoming wyomingbiodiversity.org Black Tail Bumble Bee How can you tell Bombus melanopygus it's a bumble bee? Common Bumble bees are the largest bodied bees in Wyoming. Queens can be up to two inches long, but most queens and workers are somewhat smaller than that. They're very hairy all over their bodies, and carry pollen in “baskets” on their hind legs. Did you find a bumble bee?

List of Animal Species with Ranks October 2017
Washington Natural Heritage Program List of Animal Species with Ranks October 2017 The following list of animals known from Washington is complete for resident and transient vertebrates and several groups of invertebrates, including odonates, branchipods, tiger beetles, butterflies, gastropods, freshwater bivalves and bumble bees. Some species from other groups are included, especially where there are conservation concerns. Among these are the Palouse giant earthworm, a few moths and some of our mayflies and grasshoppers. Currently 857 vertebrate and 1,100 invertebrate taxa are included. Conservation status, in the form of range-wide, national and state ranks are assigned to each taxon. Information on species range and distribution, number of individuals, population trends and threats is collected into a ranking form, analyzed, and used to assign ranks. Ranks are updated periodically, as new information is collected. We welcome new information for any species on our list.

Direct human activities such as urbanization, pesticide use, pollution, and introduction of species and pathogens as well as climate change are resulting in habitat loss and fragmentation for bees, causing declines in bee populations worldwide. Lack of suitable habitat is considered to be one of the main factors contributing to these declines. -
The Conservation Management and Ecology of Northeastern North
THE CONSERVATION MANAGEMENT AND ECOLOGY OF NORTHEASTERN NORTH AMERICAN BUMBLE BEES AMANDA LICZNER A DISSERTATION SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY GRADUATE PROGRAM IN BIOLOGY YORK UNIVERSITY TORONTO, ONTARIO September 2020 © Amanda Liczner, 2020 ii Abstract Bumble bees (Bombus spp.; Apidae) are among the pollinators most in decline globally with a main cause being habitat loss. Habitat requirements for bumble bees are poorly understood presenting a research gap. The purpose of my dissertation is to characterize the habitat of bumble bees at different spatial scales using: a systematic literature review of bumble bee nesting and overwintering habitat globally (Chapter 1); surveys of local and landcover variables for two at-risk bumble bee species (Bombus terricola, and B. pensylvanicus) in southern Ontario (Chapter 2); identification of conservation priority areas for bumble bee species in Canada (Chapter 3); and an analysis of the methodology for locating bumble bee nests using detection dogs (Chapter 4). The main findings were current literature on bumble bee nesting and overwintering habitat is limited and biased towards the United Kingdom and agricultural habitats (Ch.1). Bumble bees overwinter underground, often on shaded banks or near trees. Nests were mostly underground and found in many landscapes (Ch.1). B. terricola and B. pensylvanicus have distinct habitat characteristics (Ch.2). Landscape predictors explained more variation in the species data than local or floral resources (Ch.2). Among local variables, floral resources were consistently important throughout the season (Ch.2). Most bumble bee conservation priority areas are in western Canada, southern Ontario, southern Quebec and across the Maritimes and are most often located within woody savannas (Ch.3). -

Based on a large field sample of workers putatively belonging to either B. terrestris or B. lucorum, we here test the applicability and accuracy of a frequently used taxonomic identification key for continental European bumblebees and mtDNA restriction fragment length polymorphism (RFLP) that are diagnostic for queens to distinguish between B. terrestris and B. lucorum, two highly abundant but easily confused species in Central Europe. Bumblebee workers were grouped into B. terrestris and B. lucorum either based on the taxonomic key or their mtDNA RFLP. We also genotyped all workers with six polymorphic microsatellite loci to show which grouping better matched a coherent Hardy-Weinberg population. Firstly we could show that the mtDNA RFLPs diagnostic in queens also allowed an unambiguous discrimination of the two species. Moreover, the population genetic data confirmed that the mtDNA RFLP method is superior to the taxonomic tools available. The morphological key provided 45% misclassifications for B. -

Focusing on data-rich studies, we also synthesize recent research on potential causes of population declines. There is evidence that habitat loss, changing climate, pathogen transmission, invasion of nonnative species, and pesticides, oper- ating individually and in combination, negatively impact bumble bee health, and that effects may depend on species and locality. -

This paper presents the first documented case of nest parasitisme (usurpation) of the bumblebee Bombus balteatus Dahlbom, 1832 by the social parasite bumblebee Bombus hyperboreus Schönherr, 1809. One nest of B. balteatus was found and excavated in Hessdalen in Sør-Trøndelag, Norway in July 2003. The nest contained sexuals of Bombus hyperboreus together with workers of B. balteatus.
