Chioglossa Lusitanica Genetic Connectivity Data for the Ceira River Basin

A 2026 study by Francisco F Aguilar investigates genetic connectivity in the endemic Iberian stream salamander, Chioglossa lusitanica. The dataset includes microsatellite data from 248 individuals sampled at 88 sites across the Ceira River basin. It was used to model isolation-by-distance and isolation-by-resistance against environmental, geographical, and topographic variables.

Use Cases

• Modeling landscape resistance to gene flow based on environmental and topographic variables mentioned in the description.
• Identifying genetic clusters and admixture zones within a watershed-scale population.
• Assessing the role of river networks as corridors for genetic connectivity in riparian species.
• Evaluating the impact of human-modified lowland landscapes on genetic diversity and population structure.

Strengths

• High-resolution spatial sampling with data from 88 sites across a single watershed.
• Genetic data from 248 individual salamanders provides a substantial sample size for population-level analysis.
• Integrates multiple data types, including microsatellite genotypes, climate, primary productivity, and topography.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is geographically limited to the Ceira River basin in the western Iberian Peninsula.
