Quaternary Diversification of an Alpine Grasshopper in the Central Apennines

Francesco Forte's 1.8 GB dataset integrates genome-wide ddRAD-seq data, geometric morphometrics, and paleodistribution models for the grasshopper genus Italohippus. The data supports a model of Pleistocene climatic oscillations driving microgeographic diversification in Mediterranean sky islands. It was last updated on May 8, 2026, and is shared under a CC-BY-4.0 license.

Use Cases

• Reconstructing demographic history based on genome-wide ddRAD-seq data.
• Modeling past species distributions based on environmental niche models from the Last Glacial Maximum to the present.
• Quantifying morphological differentiation based on geometric and linear morphometrics of forewings.
• Analyzing population structure and introgression patterns based on genomic data.
• Testing biogeographic hypotheses of sky-island refugia based on integrated phylogenetic and spatial data.

Strengths

• Integrates multiple data types: genomic, morphological, and environmental niche modeling data.
• Focuses on a specific, understudied region (Central Apennines) and taxon (Italohippus grasshoppers).
• Dataset size is 1.8 GB, indicating a substantial volume of underlying data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for some analyses.
• Data may reflect geographic bias inherent to the Central Apennines study region.
