Insects, 2019 As a signature of reproductive interference (RI), we reviewed hybrid production in eusocial bumblebees in Japan, by comparing introduced Bombus terrestris with native B. ignitus in Honshu (main island of Japan) and with native B.

Bumblebees gain fitness through learning [PDF]
, 2007 Despite the widespread assumption that the learning abilities of animals are adapted to the particular environments in which they operate, the quantitative effects of learning performance on fitness remain virtually unknown. Here we evaluate the learning

Sulfoxaflor exposure reduces egg laying in bumblebees Bombus terrestris
Journal of Applied Ecology, 2019 Sulfoximine‐based insecticides, such as sulfoxaflor, are of increasing global importance and have been registered for use in 81 countries, offering a potential alternative to neonicotinoid insecticides. Previous studies have demonstrated that sulfoxaflor

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.

Microbial metabolites elicit distinct olfactory and gustatory preferences in bumblebees
Biology Letters, 2019 Animals such as bumblebees use chemosensory cues to both locate and evaluate essential resources. Increasingly, it is recognized that microbes can alter the quality of foraged resources and produce metabolites that may act as foraging cues.

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

Combined stress from parasites, pesticides and lack of flowers drives bee declines [PDF]
, 2015 Bees are subject to numerous pressures in the modern world. The abundance and diversity of flowers has declined, bees are chronically exposed to cocktails of agrochemicals, and they are simultaneously exposed to novel parasites accidentally spread by ...
