What currency do bumble bees maximize? [PDF]

PLoS ONE, 2010
In modelling bumble bee foraging, net rate of energetic intake has been suggested as the appropriate currency. The foraging behaviour of honey bees is better predicted by using efficiency, the ratio of energetic gain to expenditure, as the currency.

Individual bumblebee foraging repertoires: Implications for disease persistence

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Generalist species may be comprised of individual specialists. Individual specialization can impact disease transmission at shared resources by shaping contact patterns. Mathematical models of pollinator diseases that spread via flowers have shown that R0 can be greatly

Analysis of Pollination Services Provided by Wild and Managed Bees (Apoidea) in Wild Blueberry (Vaccinium angustifolium Aiton) Production in Maine, USA, with a Literature Review

Agronomy, 2020
Maine is the largest producer of wild blueberry (Vaccinium angustifolium Aiton) in the United States. Pollination comes from combinations of honey bees (Apis mellifera (L.)), commercial bumble bees (Bombus impatiens Cresson), and wild bees.

Linking bacterial diversity to floral identity in the bumble bee pollen basket

Environmental DNA, 2021
Multitrophic interactions are ubiquitous in nature and form the basis of biodiversity. For example, bumble bees visit flowers to collect pollen, on which a variety of bacteria exist.

Mean temperature determines whether winter variability accelerates or buffers energy loss

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Winter survival in dormant animals depends on conserving finite energy reserves, yet winter temperatures fluctuate around shifting means. In ectotherms, metabolic rate increases exponentially with temperature, so thermal variability is expected to accelerate energy loss,

Foxglove, Digitalis purpurea: An Eco-feast Plant for Bumble Bee Conservation in the Northwestern Himalayas

Sociobiology
Bumble bees (Bombus spp.) are key pollinators in Himalayan ecosystem, but habitat degradation and floral resource scarcity threaten their population. Foxglove, Digitalis purpurea, an introduced plant with deep corolla, is an important source of pollen ...

The 2024 General Election and the Rise of Reform UK

The 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

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)

Journal 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 ...

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.
