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 ...

Consequences of the high abundance of Bombus terrestris on the pollination of Vicia faba
One of the main visitors to Fabia bean crops (Vicia faba) in South America is the invasive bumblebee species Bombus terrestris. This is particularly true in Chile, where B.

Reduced nest development of reared Bombus terrestris within apiary dense human-modified landscapes
Wild bees are in decline on a local to global scale. The presence of managed honey bees can lead to competition for resources with wild bee species, which has not been investigated so far for human-modified landscapes.

Proteomic differences in seminal fluid of social insects whose sperm differ in heat tolerance
In the coming years, climate change is likely to increase the frequency and intensity of heatwaves. In many organisms, heat stress provokes physiological perturbations and can lead to decreased male fertility.
