Sex ratio variation in the bumblebee Bombus terrestris [PDF]
Patterns of sex allocation in bumblebees have been enigmatic and difficult to interpret in either a Fisherian context or in a kinselection perspective. We gathered data on several hundred laboratory-reared colonies of the bumblebee Bombus terrestris and analyzed sex allocation as a function of diapause duration and a series of variables describing ...

Assessing the acute toxicity of insecticides to the buff-tailed bumblebee (Bombus terrestris audax) [PDF]
The buff-tailed bumblebee, Bombus terrestris audax is an important pollinator within both landscape ecosystems and agricultural crops. During their lifetime bumblebees are regularly challenged by various environmental stressors including insecticides ...

Urbanization is associated with shifts in bumblebee body size, with cascading effects on pollination
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 ...

Effect of ozone exposure on the foraging behaviour of Bombus terrestris
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.

Rhythmic body movements, cyclic gas exchange and heart activity were studied at low temperature (mostly at 5°C) in bumblebee Bombus terrestris foragers. Simultaneous measurements by means of an electrolytic respirometer combined with an optical system by
