Sex ratio variation in the bumblebee Bombus terrestris [PDF]

open access: yesBehavioral Ecology, 2004
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 ...

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

open access: yesEvolutionary 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 ...

Short communication: First data on the prevalence and distribution of pathogens in bumblebees (Bombus terrestris and Bombus pascuorum) from Spain

open access: yesSpanish 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.

Effect of ozone exposure on the foraging behaviour of Bombus terrestris

open access: yesEnvironmental 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.

The behavioural responses of bumblebees Bombus terrestris to simulated rain. [PDF]

open access: yesR Soc Open Sci
Bumblebee 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 ...
