European Tetrapod Food Webs with Betweenness Centrality, 50 km Grid

Spatially explicit local food webs for European tetrapods reconstructed across a 50 by 50 kilometer grid. The dataset includes species-level betweenness centrality values used to quantify network fragility to biodiversity threats. It was created by Frederico Mestre and last updated on June 3, 2026.

Use Cases

• Modeling ecosystem-level vulnerability based on species-level threats mentioned in the description
• Analyzing spatial patterns in food-web fragility across Europe
• Assessing the structural importance of species within trophic pathways using betweenness centrality

Strengths

• Data is spatially explicit across Europe with a 50 by 50 km resolution.
• Includes derived network metrics (betweenness centrality) for quantifying structural importance.
• License is CC-BY-4.0, permitting broad reuse with attribution.

Limitations

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