Mammalian Species Bioclimatic Variables for Distribution Modeling

524 mammalian species are associated with 19 bioclimatic variables (BIO1-BIO19) extracted from WorldClim v2.1 data. Researcher su zhenhe compiled this dataset for ecological niche analysis, with a last update in April 2026.

Use Cases

• Model species distribution using BIO1 (Annual Mean Temperature) and BIO12 (Annual Precipitation) as predictors.
• Analyze ecological niche breadth by comparing variance across all 19 bioclimatic variables per species.
• Assess climate change impacts by projecting future climate scenarios onto the BIO1-BIO19 variable set.
• Correlate genomic traits with specific climatic conditions, such as temperature seasonality (BIO4) or precipitation of the warmest quarter (BIO18).

Strengths

• Data covers 524 species, providing a broad taxonomic scope.
• Includes 19 standardized bioclimatic variables per species for multi-factor analysis.
• Climatic data sourced from the authoritative WorldClim v2.1 database at 30 arc-second resolution.

Limitations

• Dataset is small at 208.5 KB, limiting the depth of analysis possible.
• Unknown row count and absence of sample data hinders assessment of data structure and completeness.
• Temporal coverage of the underlying species occurrence data is not specified, which may affect relevance.
