Chorthippus Grasshopper Genomic Data for Species Delimitation in Greece

Genome-wide ddRAD-seq data and geometric morphometrics for a Chorthippus grasshopper complex from Greece. The 136.4 MB dataset, authored by Joaquin Ortego and last updated in April 2026, reveals cryptic diversity and semi-permeable species boundaries shaped by Pleistocene climatic oscillations. Phylogenomic analyses identify two major geographic clades separated by the Corinthian Gulf and three previously unrecognized evolutionary lineages.

Use Cases

• Phylogenomic reconstruction based on genome-wide ddRAD-seq data mentioned in the description
• Species delimitation analysis based on identified cryptic evolutionary lineages
• Investigating historical hybridization and asymmetric introgression based on signatures at range margins
• Analyzing morphological stasis and wing length differentiation as a dispersal-related trait
• Studying repeated evolutionary transitions toward reduced dispersal capacity based on independent wing size reductions

Strengths

• Dataset size is 136.4 MB, indicating substantial genomic data
• Data includes genome-wide ddRAD-seq data combined with geometric morphometrics
• License is CC-BY-4.0, permitting open sharing and adaptation
• Last updated on 2026-04-15, suggesting recent maintenance

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to its focus on Greek populations
