Genomic SNP Data for Island Species Coexistence and Niche Analysis

Jui-Tse Chang's project includes two genomic datasets in VCF format, totaling 57.6 MB. The first dataset filters SNPs based on species-level grouping, while the second filters based on niche-level grouping, retaining only pure and overlap habitat niche types. The data was last updated on April 12, 2026, and is shared under a CC-BY-4.0 license.

Use Cases

• Calculate genetic differentiation (Fst) between species based on the species-level SNP dataset.
• Analyze adaptive introgression patterns using the niche-level SNP dataset filtered by habitat type.
• Model species boundary evolution by comparing SNP data from pure versus overlapping habitat niches.
• Investigate the genomic basis of coexistence in closely-related island species.

Strengths

• Data is openly available under a permissive CC-BY-4.0 license.
• The 57.6 MB size suggests a manageable dataset for analysis.
• The description specifies two distinct datasets with different filtering strategies for comparative analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description metadata is limited; actual data quality requires manual inspection after download.
