Gyne and drone production in bombus atratus (Hymenoptera: Apidae) [PDF]

, 2017
For over a decade, our research group has studied the biology of the native bumblebee, Bombus atratus, to investigate the feasibility of using it to pollinate crops such as tomato, strawberry, blackberry and peppers.

Range‐wide sampling reveals cryptic lineages but largely conserved mycorrhizal associations in the Japanese fairy lantern Thismia kobensis

PLANTS, PEOPLE, PLANET, EarlyView.
The jewel‐like flowers of Thismia are as rare as they are beautiful, often recorded from only a single site per species. Access to 15 populations of T. kobensis has enabled an uncommon, range‐wide assessment of morphology, genetics, and fungal partners. Our analyses showed that T.

Ecological Stoichiometry of Bumblebee Castes, Sexes, and Age Groups

Frontiers in Physiology, 2021
Ecological stoichiometry is important for revealing how the composition of chemical elements of organisms is influenced by their physiological functions and ecology.

An exact Schwarzschild-like solution in a bumblebee gravity model

, 2017
We have obtained an exact vacuum solution from a gravity sector contained in the minimal standard-model extension. The theoretical model assumes a Riemann spacetime coupled to the bumblebee field which is responsible for the spontaneous Lorentz symmetry ...

Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

Identification of fungi isolated from commercial bumblebee colonies [PDF]

PeerJ
Fungi can have important beneficial and detrimental effects on animals, yet our understanding of the diversity and function of most bee-associated fungi is poor.

Cosmological implications of Bumblebee vector models

, 2015
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.

Chitosan‐protected dsRNA increases efficacy against Helicoverpa armigera without compromising biosafety for pollinators

Pest Management Science, EarlyView.
Chitosan/tripolyphosphate/double‐stranded RNA (dsRNA) nanoparticles enhance RNA interference efficacy of orally delivered dsRNA against Helicoverpa armigera. Nanoparticles reduce the LC50 and do not cause deleterious effects or toxicity on beneficial insects.

Effectiveness of native bumblebees as pollinators of the alien invasive plant Impatiens glandulifera (Balsaminaceae) in Ireland

Journal of Pollination Ecology, 2009
Flowers of alien invasive plants can be pollen limited due to a lack of effective pollinators. The alien Impatiens glandulifera is predominantly visited by bumblebees in its invaded range. There bumblebees pollinate I.

Spontaneous Lorentz Violation, Nambu-Goldstone Modes, and Massive Modes

, 2010
In any theory with spontaneous symmetry breaking, it is important to account for the massless Nambu-Goldstone and massive Higgs modes. In this short review, the fate of these modes is examined for the case of a bumblebee model, in which Lorentz symmetry ...
