Genomic and Morphometric Data for 15 Galapagos Scalesia Species

396 individual genomic samples from all 15 recognized Scalesia species in the Galapagos Islands, supporting research on adaptive leaf variation. The dataset includes population-level genomic data, leaf morphometric measurements, transcriptomes from different developmental stages, and analysis scripts. It was harvested from the Borealis Dataverse repository and last updated in April 2026.

Use Cases

• Analyzing population genetic structure and nascent speciation based on intra-specific genomic data.
• Investigating the genetic basis of leaf lobing and serration using integrated genomic and morphometric data.
• Studying diversifying selection on leaf polarity pathways using provided transcriptomic files.
• Calculating population genetics metrics like dxy and genome-wide Tajima's D with the included example files.

Strengths

• Includes data from 396 individuals, providing substantial population-level sampling.
• Covers all 15 recognized species within the genus, offering a complete taxonomic scope.
• Integrates multiple data types: genomic, morphometric, and transcriptomic data for a holistic analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file sizes are unknown, which may limit suitability assessment.
• The dataset primarily contains analysis scripts and source data files; raw sequencing reads are not described as being included.
