European Physical Journal C: Particles and Fields, 2022 This work belongs to the context of the standard-model extension, in which a Lorentz symmetry violation is induced by a bumblebee field as it acquires a nonzero vacuum expectation value.

A projectome of the bumblebee central complex
bioRxiv, 2021 Insects have evolved diverse and remarkable strategies for navigating in various ecologies all over the world. Regardless of species, insects share the presence of a group of morphologically conserved neuropils known collectively as the central complex ...

Slowly rotating Einstein-bumblebee black hole solution and its greybody factor in a Lorentz violation model * [PDF]
Chinese Physics C, High Energy Physics & Nuclear Physics, 2020 We obtain an exact slowly rotating Einstein-bumblebee black hole solution by solving the corresponding $rr$ and $t\phi$ components of the gravitational field equations in both cases: A, $b_\mu=(0,b(r),0,0)$; B, $b_\mu=(0,b(r),\mathfrak{b}(\theta),0 ...

Substantial variability in morphological scaling among bumblebee colonies
Royal Society Open Science, 2022 Differences in organ scaling among individuals may play an important role in determining behavioural variation. In social insects, there are well-documented intraspecific differences in colony behaviour, but the extent that organ scaling differs within ...

Bumblebees Learn Polarization Patterns [PDF]
Current Biology, 2014 Foraging insect pollinators such as bees must find and identify flowers in a complex visual environment. Bees use skylight polarization patterns for navigation, a capacity mediated by the polarization-sensitive dorsal rim area (DRA) of their eye. While other insects use polarization sensitivity to identify appropriate habitats, oviposition sites, and ...

Urbanization is associated with shifts in bumblebee body size, with cascading effects on pollination
Evolutionary Applications, 2020 Urbanization is a global phenomenon with major effects on species, the structure of community functional traits and ecological interactions. Body size is a key species trait linked to metabolism, life‐history and dispersal as well as a major determinant ...

Super-entropy bumblebee AdS black holes
Physics Letters BMotivated by the effect of the bumblebee field on thermodynamic instability in (non)extended phase space, we study the thermodynamic instability for the bumblebee AdS black holes. For this purpose, first, we evaluate the effect of the bumblebee field (or

Toxics, 2023 Pesticide exposure has been cited as a key threat to insect pollinators. Notably, a diverse range of potential sublethal effects have been reported in bee species, with a particular focus on effects due to exposure to neonicotinoid insecticides.

Exact traversable wormhole solution in bumblebee gravity [PDF]
Physical Review D, 2018 We find a new traversable wormhole solution in the framework of the bumblebee gravity theory in which the Lorentz symmetry violation arises from the dynamics of the bumblebee vector field non-minimally coupled to gravity.

Journal of Hymenoptera Research, 2021 Climate change and increasing average temperatures are now affecting most ecosystems. Social insects such as bumblebees are especially impacted because these changes create spatial, temporal and morphological mismatches that could impede their ability to
