Genetic Structure of Rocky Mountain Tailed Frogs Across 117 Streams

Dryad data from Genevieve Metzger's 2020 study analyzes genetic structure in 2098 Rocky Mountain tailed frogs (Ascaphus montanus) collected from 117 streams. The dataset supports analysis of microsatellite variation, phylogeographic splits, and species distribution modeling in the Inland Northwest.

Use Cases

• Analyze microsatellite variation across 117 streams to assess genetic structure and diversity in Ascaphus montanus populations.
• Model species distribution changes by integrating genetic data with paleorange reconstructions and climate projections.
• Investigate the relationship between geographic distance and pairwise genetic differentiation across the species' range.
• Examine hierarchical geographic structure and genetic diversity attenuation from range center to edges using population clusters.

Strengths

• Includes genetic data from 2098 individual frogs, providing a substantial sample size for population analysis.
• Covers 117 streams across the species' distribution, offering broad spatial coverage in the Inland Northwest.
• Integrates multiple analysis frameworks: historical phylogeography, contemporary landscape genetics, and paleodistribution reconstruction.

Limitations

• The specific data format, column structure, and file size are not described, complicating initial data handling.
• Genetic analysis is focused on a single species (Ascaphus montanus) within a specific region, limiting broader taxonomic or geographic comparisons.
• Data is from a 2020 publication and may not reflect the most recent population or genetic status.
