Marbled Newt Genomic Data for Testing Species Replacement Hypotheses

A study developed 54 nuclear SNPs and one mitochondrial DNA marker to test for a genomic footprint of species displacement between Triturus marmoratus and T. pygmaeus newts in the Iberian Peninsula. The dataset was created by researchers from the Naturalis Biodiversity Center and is associated with an Open Access paper. The temporal coverage relates to conditions following the Last Glacial Maximum.

Use Cases

• Testing for hybrid zone movement based on asymmetric introgression patterns
• Modeling species distribution changes following the Last Glacial Maximum
• Investigating reproductive isolation mechanisms between closely related species
• Analyzing genomic footprints of historical species displacement

Strengths

• Dataset includes 54 nuclear SNP markers and one mitochondrial DNA marker for genetic analysis.
• Research is grounded in a specific geographic hypothesis about an enclave in the northwest Lisbon Peninsula.

Limitations

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