Bigger is better: honeybee colonies as distributed information-gathering systems

Area of Science:

• Animal Behavior
• Ecology
• Communication Systems

Background:

• Group foraging relies on effective communication for resource allocation.
• Honeybee dance communication directs foragers to floral resources based on quality.

Purpose of the Study:

• To investigate how colony size influences the benefits of communication in honeybee foraging.
• To determine if larger colonies gain more from dance communication than smaller ones.

Main Methods:

• Manipulated honeybee colony size and the capacity for dance communication.
• Assessed foraging performance and resource allocation strategies.

Main Results:

• Larger colonies showed greater benefits from communication compared to smaller colonies.
• Colony size and dance communication synergistically improved foraging efficiency.
• Net foraging gain was highest in large colonies with unimpaired communication.

Conclusions:

• Larger honeybee colonies benefit more from communication due to enhanced information gathering via parallel search.
• Communication facilitates quicker resource discovery and recruitment in larger colonies.
• The benefits stem from efficient information integration rather than solely increased competitive recruitment.
