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 evolutionary ecology of interactive synchronism: The illusion of the optimal phenotype [PDF]

open access: yes, 2017
In this article, we discuss some ecological-evolutionary strategies that allow synchronization of organisms, resources, and conditions. Survival and reproduction require synchronization of life cycles of organisms with favourable environmental ...

To provide pollinator nesting habitat, cut dead perennial stems in their first winter

open access: yesInsect Conservation and Diversity, EarlyView.
Garden management practises need to consider stem‐nesting bees and wasps to avoid destroying active nests and important nesting materials. Volunteers collected samples of dead stems (in situ where they grew) in winter, spring, summer and fall as part of a participatory research project.

Developing European conservation and mitigation tools for pollination services: approaches of the STEP (Status and Trends of European Pollinators) project [PDF]

open access: yes, 2011
Pollinating insects form a key component of European biodiversity, and provide a vital ecosystem service to crops and wild plants. There is growing evidence of declines in both wild and domesticated pollinators, and parallel declines in plants relying ...

Concentrated vulnerabilities in bees: Diet specialists have smaller geographic ranges

open access: yesInsect Conservation and Diversity, EarlyView.
Niche breadth theory predicts a positive association between range size and diet breadth, which could concentrate risk among specialists, but this is not well established for bees. Using global occurrence data (range size) and natural history collection‐derived pollen data (diet breadth), we compared these traits in 633 species from six families and ...

Gyne and drone production in bombus atratus (Hymenoptera: Apidae) [PDF]

open access: yes, 2017
For over a decade, our research group has studied the biology of the native bumblebee, Bombus atratus, to investigate the feasibility of using it to pollinate crops such as tomato, strawberry, blackberry and peppers.

Nemolizumab in prurigo nodularis up to 100 weeks: OLYMPIA LTE interim analysis

open access: yesJournal of the European Academy of Dermatology and Venereology, EarlyView.
In this interim analysis of the OLYMPIA long‐term extension trial, nemolizumab exhibited sustained efficacy and was well tolerated through 100 weeks, with most adverse events being mild/moderate. Patients showed clinically meaningful improvements in core signs and symptoms.

New fungal core microbiome members of the ground nesting bee Andrena vaga: The key to oligolecty?

open access: yesBasic and Applied Ecology
To fully understand a species, it is essential to gain knowledge about their associated (micro-)organisms. Currently, most research focuses on managed social bees and their bacterial associates.

Ecosystem services of biodiversity in organic grasslands [PDF]

open access: yes, 2011
The use of multi-species mixtures in herbage production can add value in terms of improved conditions for pollinating insects, better resource utilization, carbon sequestration, yield stability, animal health and product quality.

The Plight of the Bumble Bee: The Impact of the Bumble Bee Gut Microbiome on Pathogen Infection Rates [PDF]

open access: yes, 2016
Bumble bees are one of the most common and important non-managed pollinators of agricultural crops and are therefore vital to society’s ecological and agricultural health.
