Triturus Cristatus: Multilocus Genetic Data and LGM Climate Projections

Multilocus genetic sequences and species distribution model projections for the crested newt (Triturus cristatus) were compiled by Ben Wielstra in 2020. The data includes five genetic markers—one mitochondrial gene, three nuclear introns, and one MHC gene—paired with climate layers from the Last Glacial Maximum. This collection supports research into the postglacial recolonization of temperate Eurasia from the Carpathian Mountains.

Use Cases

• Analyzing genetic depletion using the major histocompatibility complex gene
• Reconstructing postglacial expansion routes using mitochondrial protein-coding gene sequences
• Projecting habitat suitability using Last Glacial Maximum climate layers

Strengths

• Includes five distinct genetic markers (mitochondrial, nuclear, and MHC)
• Combines phylogeographic data with species distribution modeling
• Covers historical climate projections for the Last Glacial Maximum

Limitations

• Specific record counts and column headers are not documented in the metadata
• Geographic focus is restricted to temperate Eurasia and the Carpathian region
