Study Notes

What is Communication?

Communication occurs when individuals send, receive, and respond to signals, effectively enabling interaction and information exchange.
The process involves a sender, a receiver, and a signal that carries the message.
Communication is bidirectional and can be accomplished through various channels, including visual, auditory, chemical, and electrical signals.

Visual Signals: A Visual Feast

Visual communication is most effective during daylight hours.
Animals use a wide range of visual signals, exemplified by:
- Bright colors, like bird feathers, for attracting attention and conveying information.
- Specific body movements, such as holding up a hand for "stop," for clear messaging.
- Color change, often during courtship or aggression, for visual signaling and intimidation.
In aquatic environments, visual signals primarily serve as territorial displays:
- Fish puff up to appear larger as a deterrent.
- Fish may "charge" at intruders to defend their territory.

Auditory Signals: The Power of Sound

Sound is efficient for communication over long distances.
Examples of auditory signaling include:
- Wolves howling to warn off potential threats.
- Auditory courtship displays, such as bird songs, attracting mates.
- Calling for help in situations of distress, maximizing the chances of being found.
Auditory signals can be used both defensively and offensively.

Chemical and Electrical Signals: The Silent Language

Chemical signals, primarily scents, are used for lasting messages, as they leave a scent trail that can be followed by others.
This scent trail marks territories, indicating ownership and deterring intruders.
Chemical signals can also be used to share information beneficial to the group.
- Honeybees use scent to communicate about the taste and smell of pollen, directing other bees to the best food sources.
Chemical signals are common in aquatic environments, aiding in:
- Scent trails left by female zooplankton for male attraction.
- Pheromone release by sea lampreys, signifying breeding and spawning locations.
Electrical signals are used for social communication and object detection in aquatic environments, especially in deep or murky waters where visibility is low.
