Self-organization of foraging behaviour: from simplicity to complexity without goals.

Area of Science:

• Behavioral Ecology
• Animal Physiology
• Self-Organization Theory

Background:

• Herbivores face complex foraging challenges due to dynamic physiological states and variable food quality (nutrients and toxins).
• Foraging behavior is understood as a self-organizing process, emerging from functional relationships between behavior and its environmental consequences across multiple biological levels.

Purpose of the Study:

• To explore the principles of self-organization in herbivore foraging behavior.
• To elucidate the interplay between sensory perception, postingestive feedback, and environmental factors in diet selection.

Main Methods:

• Conceptual framework integrating sensory (olfactory, gustatory, textural) and postingestive (nutrient/toxin effects) feedback.
• Analysis of how environmental changes (physical and social) influence food preferences and foraging decisions.
• Examination of self-organization principles applied to individual foraging behavior and diet variability.

Main Results:

• Herbivore diet selection is a vital affair, driven by self-organized behavioral rules responding to internal and external cues.
• Food preferences and discrimination abilities arise from integrated sensory and postingestive effects.
• Environmental factors and social learning significantly impact foraging strategies and food choices, with novelty often leading to reduced intake and increased stress.

Conclusions:

• Herbivore foraging behavior is a self-organizing system, not solely dictated by the environment, but through a continuous exchange of energy and matter.
• The ability to discriminate foods is critical for survival, and dietary variety arises from exceeding tolerance limits for specific food properties.
• Understanding these functional relationships provides a framework for analyzing herbivore-plant interactions and dietary adaptations.
