Species Co-Abundance and Environmental Data for Ecological Association Inference

A framework for inferring directed species interactions from co-abundance patterns and environmental data. The method models pair-wise associations as directed influences and jointly fits them with a habitat suitability model. The framework was developed by Sara Si moussi at the Centre Occitanie-Montpellier and demonstrated using simulated and empirical data.

Use Cases

• Inferring directed biotic interactions between species based on co-occurrence patterns.
• Modeling habitat suitability jointly with species association networks.
• Validating ecological association inference methods using simulated data.

Strengths

• Framework jointly models species associations and environmental responses, addressing a gap in existing methods.
• Methodology accounts for the asymmetric nature of ecological interactions.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
