Using optimal foraging theory to infer how groups make collective decisions.

Area of Science:

• Behavioral Ecology
• Theoretical Ecology
• Social Behavior

Background:

• Collective animal behavior offers insights into social processes like coordination and decision-making.
• A significant challenge lies in connecting individual actions during group decisions to underlying preferences.
• Optimal foraging theory provides a framework for predicting individual preferences.

Purpose of the Study:

• To link optimal foraging theory, specifically the marginal value theorem (MVT), with collective animal behavior.
• To develop testable predictions for group decision-making based on individual foraging preferences.
• To facilitate the study of group decision-making across diverse species.

Main Methods:

• Utilizing optimal foraging theory and the marginal value theorem (MVT) to predict individual preferences.
• Comparing group behavior against MVT-derived predictions under various influence models.
• Developing a formal link between optimal foraging theory and collective behavior models.

Main Results:

• The study proposes a method to formally link optimal foraging theory to collective behavior.
• This approach generates easily testable predictions for group decision-making in natural settings.
• It enables the comparison of group actions with individual-level foraging theory predictions.

Conclusions:

• Formally linking optimal foraging theory to collective behavior provides a powerful, testable framework.
• This integration is crucial for understanding the ecological and evolutionary aspects of group decision-making.
• The approach opens new avenues for studying collective decision-making in a wide array of animal species.
