When a Cornell-led team of scientists analyzed two dozen environmental factors to understand bumblebee population declines and range contractions, they expected to find stressors like changes in land use, geography or insecticides.
A common pesticide used on crops compromises a queen bumblebee's ability to lay eggs, threatening her colony with extinction, according to a study released Monday.
The absence of a single dominant bumblebee species from an ecosystem disrupts foraging patterns among a broad range of remaining pollinators in the system—from other bees to butterflies, beetles and more, field experiments ...
Bumblebee populations higher in Detroit than in some less-urbanized areas; vacant lots could be a factor
A new study of native bumblebee populations in southeastern Michigan cities found, surprisingly, that Detroit has more of the large-bodied bees than some surrounding, less urbanized locations.
New research published in the journal Proceedings of the Royal Society B has found that wild bumblebee queens are less able to develop their ovaries when exposed to a common neonicotinoid pesticide
It doesn't pay to be smart, at least for bumblebees, according to a new U of G study.
Populations of the rusty patched bumblebee, a once-common bee species, have dramatically declined during the past three decades. Many scientists who study bees believe the species may be headed toward extinction
New research led by the UK's Centre for Ecology & Hydrology has revealed for the first time that flower-rich habitats are key to enhancing the survival of bumblebee families between years.
