Indicspecies: Statistical Relationships Between Species and Site Groups

Indicspecies provides functions for assessing the statistical relationship between species occurrence or abundance and groups of sites, as described by De Cáceres & Legendre (2009). It also includes methods for measuring species niche breadth using resource categories, based on De Cáceres et al. (2011). The package is authored by Miquel De Cáceres and is available via the paperswithcode platform.

Use Cases

• Identify indicator species for specific habitat types based on occurrence/abundance relationships.
• Assess the statistical significance of species associations with environmental site groups.
• Measure species niche breadth across defined resource categories.
• Support ecological community analysis and environmental monitoring studies.

Strengths

• Implements peer-reviewed statistical methods from two published ecological papers.
• Authored by a recognized expert in the field, Miquel De Cáceres.

Limitations

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