Phrynocephalus axillaris Genetic Data from 239 Individuals Across 21 Localities

239 individual samples of the Yarkand toad-headed agama (Phrynocephalus axillaris) collected from 21 sampling localities across the Tarim Basin. The dataset integrates multi-locus molecular data, including four mitochondrial genes, three nuclear loci, and genome-wide SNPs, to investigate phylogeographic history.

Use Cases

• Analyzing mito-nuclear discordance patterns based on comparisons between mitochondrial and nuclear genetic markers.
• Reconstructing historical demographic expansions and bottlenecks based on signatures of high haplotype but low nucleotide diversity.
• Mapping fine-scale genetic structure based on genome-wide SNP data identifying six distinct clusters.
• Correlating lineage diversification events with Pleistocene glacial-interglacial cycles and desert expansion timelines.

Strengths

• Integrates data from 239 individuals across 21 sampling sites, providing a broad spatial sample.
• Combines multiple genetic data types: four mitochondrial genes, three nuclear loci, and genome-wide SNPs.
• Analysis reveals a deep maternal vicariance event dated to approximately 3.30 million years ago.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain statistical analyses.
