Amphibian Diversity Data for the Mexican Southern Altiplano Across Five Spatial Scales

The Mexican Southern Altiplano is the geographic focus of this dataset, which supports a study on improving biodiversity estimates. It contains primary and secondary data from three sources: presence-only records, stacked species distribution models, and empirical checklists from protected areas. The dataset, created by Alfredo Esparza-Orozco and last updated in May 2026, facilitates analysis of community properties like alpha and beta diversity across five spatial scales.

Use Cases

• Modeling amphibian species distributions based on presence-only data and stacked SDMs.
• Calculating alpha and beta diversity metrics, including Sørensen dissimilarity, turnover, and nestedness.
• Assessing sample coverage completeness and per-site range size for conservation planning.
• Comparing community emergent properties systematically across five distinct spatial scales.
• Validating species checklist data from well-surveyed protected areas against modeled estimates.

Strengths

• Data is structured for systematic comparison across five spatial scales (1/2°, 1/4°, 1/8°, 1/16°, and 1/32°).
• Integrates three distinct data sources (presence-only datasets, stacked SDMs, empirical checklists) for cross-validation.
• Released under a permissive CC-BY-4.0 license, facilitating reuse and sharing.
• Dataset size of 573.9 MB suggests substantial underlying data content.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling tasks.
• Data may reflect geographic or source bias inherent to the original collection methods.
