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 ...

Coinvasional disruptions to island pollinator networks

open access: yesConservation Biology, EarlyView.
Abstract Biological invasions can adversely affect pollinator diversity by threatening the maintenance of animal‐pollinated plant communities. Although most studies have examined single invasive species, accelerating species introductions driven by global trade highlight the need to understand how multiple co‐occurring invaders jointly influence ...

Strategic conservation prioritization through creating and updating the regional species of greatest conservation need list in the northeastern United States

open access: yesConservation Science and Practice, EarlyView.
Biodiversity is declining globally, underscoring the need for conservation strategies informed by regional expertise. In the northeastern United States, 14 state wildlife agencies and taxonomic experts developed the Regional Species of Greatest Conservation Need (RSGCN) list, revealing that global and national datasets captured only ~55% of regionally ...

Higher TIER bumble bees and solitary bees recommendations for a semi-field experimental design [PDF]

open access: yes, 2020
The publication of the proposed EFSA risk assessment guidance document of plant protection products for pollinators highlighted that there are no study designs for non-Apis pollinators available.

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

open access: yesEcological 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.

Bumble bees at home and at school

open access: yes, 1997
Do you know how bumble bees live and what they need? You can discover a lot about bumble bees if you watch them while they visit flowers. This article is a shortened version of a chapter from the IBRA publication Bumble bees for pleasure and profit*, and

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

open access: yesPLoS 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.

Nutritional composition of pollen stores in managed bees across European agro‐ecosystems reveals species‐specific differences but limited pesticide effects

open access: yesEcological Entomology, EarlyView.
In the pollen stores of three bee species deployed across 128 European sites, bumble bees harboured lower lipid content and higher protein‐to‐lipid ratios than honey bees and mason bees. Toxicity‐weighted pesticide risk did not alter protein‐to‐lipid ratios, but higher risk was associated with reduced protein and lipid content in the pollen stores of ...

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

open access: yesBMC 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.
