Summary
Honeybees use the waggle dance to share food source information. However, bees can stop the waggle dance if they have previously encountered danger at the food source location.
Area of Science:
- Animal Behavior
- Ecology
- Neuroscience
Background:
- Honeybees (Apis mellifera) utilize the waggle dance to communicate the location of profitable food sources to nest mates.
- This intricate communication system is crucial for colony foraging efficiency and survival.
Purpose of the Study:
- To investigate the influence of negative experiences at a food source on the waggle dance communication in honeybees.
- To understand how honeybee scouts modify their recruitment behavior based on risk assessment.
Main Methods:
- Observing waggle dances of scout bees returning from a food source.
- Introducing a simulated threat (e.g., a predator) at the food source location.
- Monitoring the duration and frequency of waggle dances after the threat experience.
Main Results:
- Scout bees that experienced danger at a food source significantly reduced the duration and frequency of their waggle dances.
- Nest mates were less likely to be recruited to the food source after the dancer had experienced danger.
Conclusions:
- Honeybee waggle dance communication is sensitive to risk assessment and past negative experiences.
- Bees can modulate their social signaling to avoid potentially dangerous foraging sites, demonstrating adaptive communication strategies.

01:03Communication
Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.
01:30Bacterial Signaling
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
01:23Overview of Cell Signaling
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

02:33Hedgehog Signaling Pathway
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
