The Effect of Foraging on Bumble Bees, Bombus terrestris, Reared under Laboratory Conditions

Insects, 2020
Bumble bees are important pollinators broadly used by farmers in greenhouses and under conditions in which honeybee pollination is limited. As such, bumble bees are increasingly being reared for commercial purposes, which brings into question whether ...

Integration Through Rights: Towards an Associational Paradigm

The Modern Law Review, EarlyView.
Integration policies in the EU and the UK have over the past two decades increasingly emphasised duties and constraints for migrants. This article challenges the duty‐based model and proposes an alternative legal conception: ‘integration through rights’, with associational rights taking a central role.

Layered abandonment: The moral interpretation of suffering in extreme confinement

Criminology, EarlyView.
Abstract Loss and rejection are central to prison life, yet how they crystallize into a more general sense of abandonment remains under‐theorized. Drawing on 64 interviews with men held in prolonged self‐isolation or serving indeterminate forvaring sentences in Denmark, we conceptualize abandonment not simply as hardship but as suffering plus ...

Investigating the impact of deploying commercial Bombus terrestris for crop pollination on pathogen dynamics in wild bumble bees

, 2013
The use of commercial bumble bees for crop pollination has been implicated in the decline of wild bumble bees through the spread of pathogens. This study investigates whether diseases from commercial bumble bees threaten native species in the UK.

The Late Agricultural Development of Central Arabian Oases—Archaeobotanical and Archaeozoological Studies of the al‐Kharj Oasis

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT While oasis settlements emerged during the Bronze Age in Eastern and Northern Arabia, the settlement process in Central Arabia was different. Excavations at al‐Yamāma—main ancient settlement of the al‐Kharj oasis (Riyadh Province, KSA)—suggest that the latter did not emerge before the second half of the first millennium BCE.

Bumble Bees of Florida

EDIS
This is a general guide to field identification, species description, and biology of the five bumble bee species Bombus spp. found in Florida. This guide to bumble bee identification in Florida would also be usable for coastal South Carolina, Georgia, Alabama, Louisiana, Mississippi, and Arkansas, but it is not comprehensive for the northern ...

Bumble Bee Watch community science program increases scientific understanding of an important pollinator group across Canada and the USA.

PLoS ONE
In a time of increasing threats to bumble bees (Hymenoptera: Apidae: Bombus), it is important to understand their ecology and distribution. As experts are limited in resources to conduct field surveys, there is potential for community scientists to help.

Brood care by male bumble bees [PDF]

Proceedings of the National Academy of Sciences, 1985
Male Bombus griseocollis (Hymenoptera: Apidae) share in the brood care of nestmates by incubating pupae (usually during the first few days after they emerge as adults). Male posture during incubation of a pupa is identical to that observed for females.

Colony‐level pollen collection reflects visitation of managed bumble bees (Bombus impatiens) in strawberry fields and surrounding landscapes without reducing pollen limitation

Agricultural and Forest Entomology, EarlyView.
We extracted pollen from colony beeswax to quantify season‐long, colony‐level resource use and tested how managed Bombus impatiens visitation and Rosaceae pollen collection relate to landscape context and strawberry pollination. Increased managed bumble bee visitation was not influenced by surrounding landcover, did not reduce pollen limitation and ...
