Honey bees use a large array of thermoregulatory mechanisms to keep the temperature of their hives, particularly their brood, tightly controlled. Coordinated responses to acute heat stress, such as heat shielding, have been well studied. In the natural environment, however, colonies are more likely to be subjected to long-term circadian heat stressors than to a single acute event. In this study, we investigated how honey bees protect their hives from chronic-localized heat stress. Over 11 weeks, we heated sections of our hives to temperatures that endangered developing brood (42 ± 1 °C) for 8 h each day. We found that after 4 weeks, heated areas contained significantly less brood (P< 0.001) and significantly more non-brood (P< 0.0001) than equally sized unheated areas. This supports the hypothesis that honey bees use a novel thermoregulatory mechanism, comb rearrangement, in response to chronic-localized heat stress. Our results provide insight into how honey bee thermoregulatory mechanisms operate in a natural context, as well as the speed and flexibility with which honey bees are able to rearrange their comb stores in response to changing thermal gradients in the hive.
