Chorus Frog Genetic Data for Phylogeographic Model Comparison

Encompassing genetic data from a chorus frog species complex, used for Bayesian model comparison in phylogeographic inference. It includes three marker types: 23 anonymous nuclear sequence loci, four mitochondrial genes, and 14 microsatellite loci. The data was collected to test biogeographic hypotheses and assess genetic structure between Pseudacris streckeri and Pseudacris illinoensis populations.

Use Cases

• Perform Bayesian model comparison using the 23 anonymous nuclear sequence loci, four mitochondrial genes, and 14 microsatellite loci to test phylogeographic hypotheses.
• Analyze genetic structure and divergence between Pseudacris illinoensis and Pseudacris streckeri populations using the multi-tiered marker set.
• Infer migration models and population expansion routes from central Texas refugia based on the collected genetic data.
• Define genetically distinct management units for disjunct northern and southern Pseudacris illinoensis regions using the microsatellite and sequence data.

Strengths

• Includes three distinct genetic marker types (23 nuclear loci, 4 mitochondrial genes, 14 microsatellites) for multi-timescale analysis.
• Data was analyzed using a Bayesian model comparison approach for rigorous phylogeographic inference.
• Focuses on a fragmented species complex (Pseudacris streckeri/illinoensis) providing a system for studying biogeography and genetic variation.

Limitations

• The specific sample size (number of individuals or populations sequenced) and data volume (rows) are not provided.
• The raw data structure (e.g., alignment files, genotype matrices) and file formats are unspecified, requiring user interpretation.
• Geographic coverage is described but not quantified (e.g., number of sampling sites, precise coordinates).
