Embedding information flows within ecological networks

Area of Science:

• Ecology
• Network Theory
• Ecological Interactions

Background:

• Ecological networks are crucial for understanding community stability and predicting extinction risks.
• Traditional research focused on matter/energy flow (e.g., feeding, pollination).
• Species interactions also involve information exchange influencing behavior and movement.

Purpose of the Study:

• To propose the integration of information exchange into ecological network analysis.
• To introduce the concept of 'information networks of nature'.
• To analyze how information flow affects community structure and dynamics.

Main Methods:

• Developing multilayer network models integrating information and matter/energy flow.
• Classifying information links based on sender-receiver relationships within food web motifs.
• Analyzing network properties like pathway length and modularity.

Main Results:

• Information exchange forms a crucial, often neglected, aspect of community organization.
• Integration reveals novel classifications of information links.
• Synthesizing information and matter flow in multilayer networks leads to denser species aggregation and shorter pathways.
• Increased interconnectedness raises the risk of perturbation spread.

Conclusions:

• Understanding information networks is vital for predicting community dynamics under global change.
• The interconnectedness driven by information exchange can destabilize ecological communities.
• Future research should incorporate information flow into ecological network assessments.
