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

The populations of honeybees and bumblebees have been decreasing around the world in the recent decades. A variety of pathogens and parasites, including bacteria, fungi, protozoa, nematodes, mites and insects play signi ficant role in honeybee and ...

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

Exact traversable wormhole solution in bumblebee gravity [PDF]
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.

BumbleKey: an interactive key for the identification of bumblebees of Italy and Corsica (Hymenoptera, Apidae) [PDF]
BumbleKey is a matrix-based, interactive key to all 45 species of bumblebees of Italy and Corsica. The key allows to identify adult males and females (queens and workers) using morphological characters. The key is published online, open-access, at http://

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.

Cosmological implications of Bumblebee vector models
The Bumblebee Model of spontaneous Lorentz symmetry breaking is explored in a cosmological context, considering a single non-zero time component for the vector field.

Substantial variability in morphological scaling among bumblebee colonies
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]
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 ...
