Unveiling the submerged secrets: bumblebee queens' resilience to flooding
Biol Lett. 2024 Apr;20(4):20230609. doi: 10.1098/rsbl.2023.0609. Epub 2024 Apr 17.ABSTRACTIn a previous study, an experimental oversight led to the accumulation of water filling a container housing diapausing bumblebee queens. Surprisingly, after draining the water, queens were found to be alive. This observation raises a compelling question: can bumblebee queens endure periods of inundation while overwintering underground? To address this question, we conducted an experiment using 143 common eastern bumblebee (Bombus impatiens) queens placed in soil-filled tubes and subjected to artificially induced diapause in a refriger...

Bumblebee nest departures under low light conditions at sunrise and sunset
Biol Lett. 2024 Apr;20(4):20230518. doi: 10.1098/rsbl.2023.0518. Epub 2024 Apr 10.ABSTRACTOnly a few diurnal animals, such as bumblebees, extend their activity into the time around sunrise and sunset when illumination levels are low. Low light impairs viewing conditions and increases sensory costs, but whether diurnal insects use low light as a cue to make behavioural decisions is uncertain. To investigate how they decide to initiate foraging at these times of day, we observed bumblebee nest-departure behaviours inside a flight net, under naturally changing light conditions. In brighter light bees did not attempt to return...

First-sight recognition of touched objects shows that chicks can solve Molyneux's problem
Biol Lett. 2024 Apr;20(4):20240025. doi: 10.1098/rsbl.2024.0025. Epub 2024 Apr 3.ABSTRACTIf a congenitally blind person learns to distinguish between a cube and a sphere by touch, would they immediately recognize these objects by sight once their vision is restored? This question, posed by Molyneux in 1688, has puzzled philosophers and scientists since then. To overcome ethical and practical difficulties in the investigation of cross-modal recognition, we studied inexperienced poultry chicks, which can be reared in darkness until the moment of a visual test with no detrimental consequences. After hatching chicks in darknes...
