Bumblebees [PDF]

open access: yes, 2010
Since bumblebees are a group associated with cool climates, Britain supports a large proportion (~10%) of the world's bumblebee fauna. However, three of our 25 species have become extinct, and seven species are Biodiversity Action Plan (BAP) listed, a higher proportion than for any other insect group.

Walking bumblebees see faster

open access: yesProceedings of the Royal Society B: Biological Sciences, 2023
The behavioural state of animals has profound effects on neuronal information processing. Locomotion changes the response properties of visual interneurons in the insect brain, but it is still unknown if it also alters the response properties of photoreceptors. Photoreceptor responses become faster at higher temperatures.

Genus-Wide Characterization of Bumblebee Genomes Provides Insights into Their Evolution and Variation in Ecological and Behavioral Traits

open access: yesMolecular biology and evolution, 2020
Bumblebees are a diverse group of globally important pollinators in natural ecosystems and for agricultural food production. With both eusocial and solitary life-cycle phases, and some social parasite species, they are especially interesting models to ...

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 ...

Strain-level analysis reveals the vertical microbial transmission during the life cycle of bumblebee

open access: yesMicrobiome, 2021
Microbial acquisition and development of the gut microbiota impact the establishment of a healthy host-microbes symbiosis. Compared with other animals, the eusocial bumblebees and honeybees possess a simple, recurring, and similar set of gut microbiota ...

Lipolytic Activity of a Carboxylesterase from Bumblebee (Bombus ignitus) Venom

open access: yesToxins, 2021
Bee venom is a complex mixture composed of peptides, proteins with enzymatic properties, and low-molecular-weight compounds. Although the carboxylesterase in bee venom has been identified as an allergen, the enzyme’s role as a venom component has not ...
