Bumble bees (Hymenoptera: Apidae: Bombus terrestris) collecting honeydew from the giant willow aphid (Hemiptera: Aphididae) [PDF]

open access: yesJournal of Hymenoptera Research, 2019
Only rarely have bumble bees (Bombus) been observed collecting honeydew from aphids (Aphididae) feeding on phloem sap. This behavior may be rare because the percentage of sugar in honeydew egested from aphids is generally well below the sugar ...

The 2024 General Election and the Rise of Reform UK

open access: yesThe Political Quarterly, Volume 96, Issue 1, Page 91-101, January/March 2025.
Abstract This article examines the social base of support for Reform UK. Did Nigel Farage's new party depend on the same types of ‘left behind’ voters who had previously backed UKIP? Do the results of the 2024 election suggest a hardening of the social divides that underpinned the rise of UKIP? Or has Britain's Eurosceptic and anti‐immigration movement

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

open access: yesInsects, 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 ...

125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

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

open access: yesArabian 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.

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

open access: yesAgricultural 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 ...

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks

open access: yesAgricultural and Forest Entomology, EarlyView.
Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Bumble Bees of Florida

open access: yesEDIS
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 ...

Brood care by male bumble bees [PDF]

open access: yesProceedings 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.
