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 ...

Porównano kilka metod stymulacji zakładania gniazd (ze szczególnym uwzględnieniem wykorzystania kokonów Bombus terrestris) przez matki B. lapidarius i B. hortorum. Stwierdzono, że procent matek B. lapidarius, które wybudowały pierwszą miseczkę na jaja na

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
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

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.

The global movement of bees for agricultural pollination services can affect local pollinator populations via hybridization. When commercial bumblebees are of the same species but of different geographic origin, intraspecific hybridization may result in ...

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.
