Ongoing research into the effect of environmental change on the buzzing of bees reveals that high temperatures and exposure to heavy metals reduces the frequency (and audible pitch) of non-flight wing vibrations, which could have consequences on the effectiveness of bee communication and their role as pollinators.



Summary

Bees use wing vibrations for communication, not just flight. Recent research shows environmental changes, specifically high temperatures and heavy metal exposure, are lowering the frequency of these vibrations, effectively lowering the “pitch” of their buzzing. This altered buzzing could disrupt bee communication, potentially impacting their ability to coordinate foraging, warn of danger, and ultimately, affecting their pollination efficiency. Consequently, changes to bee buzzing driven by environmental stressors could have significant ecological and economic consequences.
