Invited Seminar at CES on 15 June 2022 at 11:45 am titled "Colony and individual-level response to heat stress inside a honey bee nest" by Jitesh Jhawar from Humboldt postdoctoral fellow, Max Planck Institute for Animal Behavior, Konstanz, Germany
Honeybees are a well known example of self-organized collective systems. Individuals perform tasks and coordinate their behavior in a way that translates to the colony-level organization. Stressful situations such as high temperatures are common in the environment. Specifically, during heat stress periods individuals show enhanced behaviors such as fanning and spreading water. During such conditions, it is not understood how individuals in the colony vary in their behavior, what factors determine changes in behavior, and how these translate to the colonylevel response. We examine the honey bee heat stress response by introducing multiple agematched cohorts (i.e. several thousand tagged bees) into an observation hive, and analyzing their movement behavior. We use the behavior over time for each individual to extract the dominant modes of response, and furthermore ask how previous behavior predicts how an individual responds during heat stress. Broadly, such large scale colony-level analysis can reveal if there are general principles of reorganization that honeybees adhere to when encountered with sudden changes or stress.
