190 islands across 30 archipelagos provide a global test of island biogeography theory for Coccinellidae. Native and alien species counts are compiled with island-level environmental predictors like area and distance to mainland. Marine Baujeu of CIRAD created this dataset, last updated in April 2026.
Use Cases
- Modeling native species richness based on island area and isolation metrics mentioned in the description
- Analyzing alien species establishment patterns in relation to human-mediated introductions
- Testing the Equilibrium Theory of Island Biogeography using compiled global species data
- Investigating the relationship between island elevation and Coccinellidae diversity
Strengths
- Covers 190 islands across 30 archipelagos, providing a global scope
- Includes two distinct species categories: native and alien, as defined in the description
- Contains multiple island-level environmental predictors, such as area and distance to mainland
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
