Radiative corrections in bumblebee electrodynamics
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2015 We investigate some quantum features of the bumblebee electrodynamics in flat spacetimes. The bumblebee field is a vector field that leads to a spontaneous Lorentz symmetry breaking.

Mapping Bumblebee Community Assemblages and Their Associated Drivers in Yunnan, China. [PDF]
Biology (Basel)Bumblebees are among the most important wild pollinators; however, their populations are declining worldwide due to factors such as climate change, habitat loss, and pesticide use.

Light Sensitive Bumblebee Species Are Associated With Forest Habitat and Forest-Dominated Landscapes. [PDF]
Ecol EvolWe investigate whether the eye parameter of bumblebees—a visual trait measuring the tradeoff between light sensitivity and visual resolution—is associated with: (i) local habitats, (ii) forest cover at the landscape scale (1 km radius), and (iii) the ...

Bumblebee Pollination Enhances Yield and Flavor of Tomato in Gobi Desert Greenhouses
Agriculture, 2022 Bumblebee pollination is crucial to the production of tomato in protected cultivation. Both tomato yield and flavor play important roles in attracting attentions from growers and consumers.

Radiative corrections in metric-affine bumblebee model
Physics Letters B, 2022 We consider the metric-affine formulation of bumblebee gravity, derive the field equations, and show that the connection can be written as Levi-Civita of a disformally related metric in which the bumblebee field determines the disformal part.

Effect of pollinator size on seed set in Lamium album var. barbatum [PDF]
Plant Ecology and Evolution, 2021 Background and aims – Previous researchers have demonstrated that geographic variation in pollinator community composition can generate diversity in the floral traits of animal-pollinated plants.

Genus-Wide Characterization of Nuclear Mitochondrial DNAs in Bumblebee (Hymenoptera: Apidae) Genomes
Insects, 2021 In eukaryotes, DNA of mitochondria is transferred into the nucleus and forms nuclear mitochondrial DNAs (NUMTs). Taking advantage of the abundant genomic resources for bumblebees, in this study, we de novo generated mitochondrial genomes (mitogenomes ...

Basic and Applied Ecology, 2022 Many bumblebee species are declining due to a loss of semi-natural habitats in agricultural landscapes resulting in diminished forage and nest sites. Anecdotal experience indicates that bumblebees nest in straw bales, but scientific evidence is lacking ...
