Common eastern bumblebee queens’ ability while hibernating could help it endure flooding, scientists say
Bumblebees might be at home in town and country but now researchers have found at least one species that is even more adaptable: it can survive underwater.
The team said its next priority was to explore whether the results hold for other species of bumblebee. “After that, of course, curiosity led the way to conducting a full experiment with a lot of repetitions,” said Rondeau., the scientists describe how they took 143 unmated, hibernating queens of the common eastern bumblebee and placed each in its own plastic tube containing damp topsoil. The tubes were then fitted with perforated lids and kept in a dark refrigerated unit for a week.
The results reveal survival rates were similar regardless of the duration and conditions the queens had been subjected to – indeed 88% of the controls, and 81% of the queens that were submerged for a week, were still alive at eight weeks. However, queens with a higher weight had a greater chance of survival.
