The potential of electricity transmission corridors in forested areas as bumblebee habitat [PDF]

open access: yesRoyal Society Open Science, 2016
Declines in pollinator abundance and diversity are not only a conservation issue, but also a threat to crop pollination. Maintained infrastructure corridors, such as those containing electricity transmission lines, are potentially important wild ...

New locality records and additional information on the Bombus (Hymenoptera: Apidae) fauna of Turkey

open access: yesБіологічні студії, 2021
Background. The article presents the results of the research on bumblebees (Hymenoptera: Apidae: Bombus) housed in the Lodos Entomological Museum (Ege University, Izmir, Turkey). Bumblebees play a key role in ecosystems as pollinators.

Endosymbionts that threaten commercially raised and wild bumble bees (Bombus spp.)

open access: yesJournal of Pollination Ecology, 2023
Bumble bees (Bombus spp.) are important pollinators for both wild and agriculturally managed plants. We give an overview of what is known about the diverse community of internal potentially deleterious bumble bee symbionts, including viruses, bacteria ...

Using the combined gene approach and multiple analytical methods to improve the phylogeny and classification of Bombus (Hymenoptera, Apidae) in China [PDF]

open access: yesZooKeys, 2020
Bumble bees are vital to our agro-ecological system, with approximately 250 species reported around the world in the single genus Bombus. However, the health of bumble bees is threatened by multiple factors: habitat loss, climate change, pesticide use ...

An evidence-based rationale for a North American commercial bumble bee clean stock certification program

open access: yesJournal of Pollination Ecology, 2023
The commercial production and subsequent movement of bumble bees for pollination of agricultural field and greenhouse crops is a growing industry in North America and globally.

Sensitivity of commercial pumpkin yield to potential decline among different groups of pollinating bees [PDF]

open access: yesRoyal Society Open Science, 2017
The yield of animal-pollinated crops is threatened by bee declines, but its precise sensitivity is poorly known. We therefore determined the yield dependence of Hokkaido pumpkin in Germany on insect pollination by quantifying: (i) the relationship ...

Novel data support model linking floral resources and honey bee competition with bumble bee abundances in coastal scrub

open access: yesJournal of Pollination Ecology, 2021
Growing evidence supports that many bee populations are declining, with potentially serious consequences for pollination services. Mechanistic models that predict bee abundances from drivers like floral resource availability can be a powerful way to ...

Male-biased night foraging by bumblebees (Hymenoptera, Apidae, Bombus spp.) in Taiwan [PDF]

open access: yesJournal of Hymenoptera Research, 2023
Known nocturnal behaviors of bees in the superfamily Apoidea, including the genus Bombus, were almost exclusively of females. Here we report observations of active free-ranging male Bombus at night in the plant nursery of the Fushan Research Center ...

La importancia del color: morfos florales, tasas de visita y éxito reproductivo en el arbusto Sarothamnus scoparius

open access: yesEcología Austral, 2015
El estudio de la variación intraespecífica del color de las flores nos permite comprender mejor el papel de los polinizadores como agentes de selección, y su efecto sobre la abundancia de las variantes florales.
