Effects of spinetoram and glyphosate on physiological biomarkers and gut microbes in Bombus terrestris

open access: yesFrontiers in Physiology, 2023
The sublethal effects of pesticide poisoning will have significant negative impacts on the foraging and learning of bees and bumblebees, so it has received widespread attention.

Conserved, yet disruption-prone, gut microbiomes in neotropical bumblebees

open access: yesmSphere, 2023
Bumblebees are important pollinators in natural ecosystems and agriculture, but many species are declining. Temperate-zone bumblebees have host-specific and beneficial gut microbiomes, which may have a role in mediating the effects of stressors. However,

Floral Categorization by Bumblebees: The Perceptual and the Functional [PDF]

open access: yesAnimal Behavior and Cognition, 2022
This study examines generalization and perceptual similarity judgments in bumblebees (Bombus impatiens) and addresses whether category formation of floral stimuli is based upon perceptual floral features alone or foraging experiences from reward ...

Humans Share More Preferences for Floral Phenotypes With Pollinators Than With Pests

open access: yesFrontiers in Plant Science, 2021
Studies on the selection of floral traits usually consider pollinators and sometimes herbivores. However, humans also exert selection on floral traits of ornamental plants.

BumbleBee: A Transformer for Music

open access: yesCoRR, 2021
We will introduce BumbleBee, a transformer model that will generate MIDI music data . We will tackle the issue of transformers applied to long sequences by implementing a longformer generative model that uses dilating sliding windows to compute the attention layers. We will compare our results to that of the music transformer and Long-Short term memory

The Pathogens Spillover and Incidence Correlation in Bumblebees and Honeybees in Slovenia

open access: yesPathogens, 2021
Slovenia has a long tradition of beekeeping and a high density of honeybee colonies, but less is known about bumblebees and their pathogens. Therefore, a study was conducted to define the incidence and prevalence of pathogens in bumblebees and to ...

Gap perception in bumblebees [PDF]

open access: yesJournal of Experimental Biology, 2018
Abstract A number of insects fly over long distances below the natural canopy where the physical environment is highly cluttered consisting of obstacles of varying shape, size and texture. While navigating within such environments animals need to perceive and disambiguate environmental features that might obstruct their flight. The most

Non-Apis (Bombus terrestris) versus honeybee (Apis mellifera) acute oral and contact sensitivity – Preliminary results of ECPA company data evaluation

open access: yesJulius-Kühn-Archiv, 2018
A preliminary data evaluation was conducted by ECPA companies to compare the sensitivity of bumblebees (Bombus terrestris) with the sensitivity of honeybees (Apis mellifera).

Foraging Bumblebees Selectively Attend to Other Types of Bees Based on Their Reward-Predictive Value

open access: yesInsects, 2020
Using social information can be an efficient strategy for learning in a new environment while reducing the risks associated with trial-and-error learning. Whereas social information from conspecifics has long been assumed to be preferentially attended by

Bumblebees of the Subarctic Region in European Russia—Their Significance and Conservation

open access: yesBiology and Life Sciences Forum, 2022
Regarding the bumblebee fauna, a number of regions of Russia are still insufficiently studied. These include Arkhangelsk Region, a large territory that is partly located in the subarctic region of Northern European Russia.
