Spatial Vision in Bombus terrestris [PDF]

open access: yesFrontiers in Behavioral Neuroscience, 2016
Bombus terrestris is one of the most commonly used insect models to investigate visually guided behavior and spatial vision in particular. Two fundamental measures of spatial vision are spatial resolution and contrast sensitivity. In this study, we report the threshold of spatial resolution in B.

Genomic Features Of A Bumble Bee Symbiont Reflect Its Host Environment [PDF]

open access: yes, 2014
Here, we report the genome of one gammaproteobacterial member of the gut microbiota, for which we propose the name >Candidatus Schmidhempelia bombi,> that was inadvertently sequenced alongside the genome of its host, the bumble bee, Bombus impatiens ...

Bumble bees exhibit body size clines across an urban gradient despite low genetic differentiation

open access: yesScientific Reports, 2022
Environmental heterogeneity resulting from human-modified landscapes can increase intraspecific trait variation. However, less known is whether such phenotypic variation is driven by plastic or adaptive responses to local environments.

Effects of habitat composition and landscape structure on worker foraging distances of five bumblebee species [PDF]

open access: yes, 2016
Bumblebees (Bombus spp.) are important pollinators of both crops and wild flowers. Their contribution to this essential ecosystem service has been threatened over recent decades by changes in land use, which have led to declines in their populations.
