Active space

Definition

The area or volume within which the concentration of an airborne pheromone or chemical signal is high enough to be detected by an organism, typically used in the context of insect behavior and communication.

Etymology

Derived from the words 'active', from Latin 'activus' meaning 'dynamic or energetic', and 'space', from Latin 'spatium' meaning 'room or distance'.

Example

Usage Notes

The concept of active space is important in understanding how insects communicate over distances, and can vary significantly depending on environmental conditions and the type of pheromone.
