Eating versus heating: a study of the allocation of workers between foraging and nest incubation in bumble bees
1. Bumble bees are important eusocial pollinators whose worker caste, fuelled by nectar sugar, accelerate colony growth through brood incubation, but allocating workers to nectar foraging couldExpand
Ecology and Evolution of Cuckoo Bumble Bees
Abstract Most social insect lineages contain socially parasitic cheater species that, rather than produce their own workers, infiltrate the nests of closely related social species and force the hostsExpand
Bumble Bees (Hymenoptera: Apidae: Bombus spp.) of Interior Alaska: Species Composition, Distribution, Seasonal Biology, and Parasites
TLDR
The objectives of this study were to provide baseline data on species composition, distribution, seasonal biology, and parasites of the genus Bombus at three major agricultural locations within Alaska to lay the groundwork for future research on bumble bee pollination in Alaska. Expand
The Hot-Blooded Insects
Molecular characteristics of Bombus (Alpinobombus) polaris from North Greenland with comments on its general biology and phylogeography
TLDR
It is concluded that the survival of pollinating species in the high Arctic under the changing climate scenario depends not only on the weather but also on an individual’s opportunity to continue to locate suitable food sources, i.e. pollen and nectar in the case of B. polaris. Expand
Ensuring access to high-quality resources reduces the impacts of heat stress on bees
TLDR
This study suggests that landscape management actions that ensure access to high-quality resources could reduce the impacts of heat stress on bee decline, and suggests that small colonies were much more sensitive to heat and nutritional stresses than large ones. Expand
Taxonomy and distribution of bumblebees (Hymenoptera: Apidae) of district Skardu, Gilgit Baltistan
Survey was conducted in different localities of district Skardu, Gilgit Baltistan during the year of 20162017 to record species composition belonging to genus Bombus Latreille 1802. It was discoveredExpand
The power and efficiency of brood incubation in queenless microcolonies of bumble bees (Bombus terrestris L.)
TLDR
The thermogenic power and sugar consumption of orphaned nests of bumble bee workers (microcolonies) were investigated under laboratory conditions to explore the basis of incubation. Expand
Adding attractive semio-chemical trait refines the taxonomy of Alpinobombus (Hymenoptera: Apidae)
TLDR
This work describes and compares the CLGS of 161 male specimens of nine Alpinobombus taxa and confirms the species status of alpinus, balteatus, helleri, hyperboreus, kirbiellus, natvigi, neoboreUS, polaris, and pyrrhopygus and the synonymy of helleri (Alps) with al pinus (Sweden). Expand
