Overview

General Features of Chemical Communication

• Contrasts between chemical, auditory, and visual signals
• Forms of chemical communication
• Identifying chemical signals: Function before structure

Production of Chemical Signals

• Types of chemicals used for intraspecific communication
• Production mechanisms
• Dissemination methods

Transmission of Chemical Signals

• Diffusion
• Transmission by current flow
• Other environmental effects on chemical signal transmission

Chemoreception

• Coupling from the medium to the receptor
• Chemosensory reception
• Finding the source
