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 ...

A Test of Bombus terrestris Cocoon and other Common Methods for Nest Initiation in B. lapidarius and B. hortorum

open access: yesJournal of Apicultural Science, 2012
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

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.

Interrelations of gas exchange cycles, body movements and heartbeats in the foragers of bumblebee Bombus terrestris (Hymenoptera: Apidae) at low temperatures

open access: yesEuropean Journal of Entomology, 2002
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

open access: yesJournal of Pollination Ecology, 2021
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.

Genomic divergence and a lack of recent introgression between commercial and wild bumblebees (Bombus terrestris)

open access: yesEvolutionary Applications, 2022
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

open access: yesRoyal Society Open Science, 2023
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.
