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 ...

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 ...

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

Agricultural 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

Toward an Indigenous Curatorial Practice: Learning From Tłı̨chǫ Metaphors of Care to Establish Principles of Curation

American Anthropologist, EarlyView.
ABSTRACT The displacement of items of cultural heritage from Indigenous communities is continually perpetuated through their appropriation into collection systems that are inappropriate to Indigenous laws and customs. This paper presents the efforts of the Tłı̨chǫ Government (TG) to address such issues by creating a system that is rooted within its ...

The transcription factor Krüppel homolog 1 is linked to hormone mediated social organization in bees

BMC Evolutionary Biology, 2010
Background Regulation of worker behavior by dominant queens or workers is a hallmark of insect societies, but the underlying molecular mechanisms and their evolutionary conservation are not well understood.

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.

Tachinidae (Diptera) as Floral Visitors and Pollinators in Natural and Managed Systems

Entomologia Experimentalis et Applicata, EarlyView.
We review the roles of bristle flies (Tachinidae) as pollinators in natural and managed systems. We find that most tachinid genera visit flowers and that floral‐adapted mouthparts have evolved repeatedly many times in the family. We review patterns of floral specificity and assess the efficacy of tachinids as pollinators with case studies.

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

Ecological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Influence of elevation, climate, snowmelt and floral abundance on body size of solitary bees

Ecological Entomology, EarlyView.
We measured body size in bee species from a 10‐year specimen collection from Colorado sub‐alpine meadows (2450–3450 m) and tested effects of elevation and annual snowmelt, climate and floral abundance. 2 out of 4 bee species collected across a broad elevation range showed a decline in body size with higher elevations; the other two showed no effect ...
