Dynamic instability analysis for bumblebee black holes: The odd parity
Physical Review DSpherical black-hole (BH) solutions have been found in the bumblebee gravity where a vector field nonminimally couples to the Ricci tensor. We study dynamic (in)stability associated with the gravitational and vector perturbations of odd parity against ...

A study in Molecular Biology and Evolution reports de novo genome sequences for 17 bumblebee species spanning all 15 subgenera. This valuable resource should provide a deeper biological understanding of these commercially and ecologically important pollinators.

Many important crops – not to mention more humble plants – rely on insects to pollinate them and ensure the arrival of the next generation. Thus, any decline in insect numbers has attendant ecological and economic problems. This is a particular problem for bumblebees in the UK, whose numbers have declined over the past 50 years, largely because of ...

Bumblebee visitation problem is defined on connected graphs where a mobile agent, called Bumblebee, moves along the edges under some rules to achieve some optimization function. We prove this problem to be NP-hard for general graphs. We present a linear time algorithm for this problem on trees.

Reflection on human creativity cannot begin with the consideration of a startling but isolated act for that act may be an empty aberration in the context of a person's life. Nor can the eccentricity of a whole life be the starting point for that life may be merely mad in the context of its society and culture.

Nectar yeasts enhance the interaction between Clematis akebioides and its bumblebee pollinator.
Plant biology, 2019It has been hypothesised that intense metabolism of nectar-inhabiting yeasts (NIY) may change nectar chemistry, including volatile profile, which may affect pollinator foraging behaviours and consequently plant fitness.

Bumblebees adapt for turbulence
Journal of Experimental Biology, 2017![Graphic][1] Everyone has heard the myth that bumblebees defy the laws of physics when they fly. Of course, we know that this is not the case, but we still know surprisingly little about how bumblebees fly in outdoor environments, where the weather can change abruptly.

The European bumblebee, Bombus terrestris, is an invasive eusocial species whose distribution is expanding greatly beyond its native range because numerous colonies are imported to or locally produced in non-native countries for pollination of agricultural crops.
