The final moments of landing in bumblebees, Bombus terrestris

Journal of Comparative Physiology A: Neuroethology, Sensory, Neural, and Behavioral Physiology, 2016
In comparison to other insects, like honeybees, bumblebees are very effective pollinators. Even though landing is a crucial part of pollination, little is known about how bumblebees orchestrate the final, critical moments of landing. Here, we use high-speed recordings to capture the fine details of the landing behaviour of free-flying bumblebees ...

Learning of geometry and features in bumblebees (Bombus terrestris).

Journal of Comparative Psychology, 2013
Bumblebees (Bombus terrestris) were trained to find one of the four exit holes located in the corners of an enclosed environment with a distinctive geometry (a rectangular cage). Panels located at the corners provided nongeometric, featural cues. Between trials bumblebees were passively disoriented to disable dead reckoning.

Heritability of sperm length in the bumblebee Bombus terrestris

Genetica, 2006
Sperm length is highly variable, both between and within species, but the evolutionary significance of this variation is poorly understood. Sexual selection on sperm length requires a significant additive genetic variance, but few studies have actually measured this.

Demographic Consequences of Drift in Contiguous Hives of Bombus terrestris

Journal of Economic Entomology, 2007
The objective of this experiment was 1) to quantify drift between bumblebee, Bombus terrestris L., colonies when hives are vertically stacked; and 2) to measure the impact of drift on the colony growth. The experiment was conducted outside, in an open area, at three sites with one stack of three colonies per site.

Structural and functional analysis of aquaporins in Bombus terrestris

International Journal of Biological Macromolecules
Bombus terrestris are efficient pollinators in forestry and agriculture, with higher cold tolerance than other bees. Yet, their cold tolerance mechanism remains unclear. Aquaporins (AQPs) function as cell membrane proteins facilitating rapid water flow, aiding in osmoregulation.
