Urbanization is associated with shifts in bumblebee body size, with cascading effects on pollination
Evolutionary Applications, 2021 Urbanization is a global phenomenon with major effects on species, the structure of community functional traits and ecological interactions. Body size is a key species trait linked to metabolism, life‐history and dispersal as well as a major determinant ...

Winter Active Bumblebees (Bombus terrestris) Achieve High Foraging Rates in Urban Britain
, 2010 BackgroundForaging bumblebees are normally associated with spring and summer in northern Europe. However, there have been sightings of the bumblebee Bombus terrestris during the warmer winters in recent years in southern England.

No trade-off between learning speed and associative flexibility in bumblebees: a reversal learning test with multiple colonies [PDF]
, 2012 Potential trade-offs between learning speed and memory-related performance could be important factors in the evolution of learning. Here, we test whether rapid learning interferes with the acquisition of new information using a reversal learning paradigm.

Spanish Journal of Agricultural Research, 2017 Bumblebees provide pollination services not only to wildflowers but also to economically important crops. In the context of the global decline of pollinators, there is an increasing interest in determining the pathogen diversity of bumblebee species.

, 2008 The impact of the microsporidium Nosema bombi on Bombus terrestris was studied by recording mating, hibernation success, protein titre in haemolymph, weight change during hibernation, and colony founding of queens that were inoculated with N.

The behavioural responses of bumblebees Bombus terrestris to simulated rain. [PDF]
R Soc Open SciBumblebee activity typically decreases during rainfall, putting them under the threat of the increased frequency of precipitation due to climate change. A novel rain machine was used within a flight arena to observe the behavioural responses of bumblebees ( Bombus terrestris ) to simulated ...

Effect of ozone exposure on the foraging behaviour of Bombus terrestris
Environmental Pollution, 2023 Tropospheric ozone (O3) mixing ratios have increased substantially since preindustrial times and high O3 peaks are increasingly common. Plant-pollinator interactions are central to natural ecosystem functioning and food production systems but could be negatively affected by unfavourable environmental conditions such as elevated O3.

Identification and functional characterisation of a novel N-cyanoamidine neonicotinoid metabolising cytochrome P450, CYP9Q6, from the buff-tailed bumblebee Bombus terrestris [PDF]
, 2019 Recent work has shown that two bumblebee (Bombus terrestris) cytochrome P450s of the CYP9Q subfamily, CYP9Q4 and CYP9Q5, are important biochemical determinants of sensitivity to neonicotinoid insecticides.
