Transcriptomic Divergence Data for Gryllus Field Cricket Species

Dryad hosts transcriptomic variation data from a study on cryptic field cricket species Gryllus rubens and G. texensis. The dataset supports analyses of demographic history, genetic divergence, and signatures of selection, including FST outlier loci. Author Thomas Blankers published the data in 2020 under a CC0 license.

Use Cases

• Model demographic history and bidirectional gene flow between Gryllus rubens and G. texensis using transcriptomic variation.
• Identify FST outlier loci to screen for signatures of selection controlling mating behavior divergence.
• Compare observed FST distributions against coalescent simulations under various demographic scenarios to disentangle effects of gene flow and selection.
• Analyze genetic divergence patterns to investigate the peripatric origin and bottleneck history of G. rubens.

Strengths

• Data originates from a peer-reviewed study published in 2020, providing a recent scientific snapshot.
• Focuses on two cryptic species with highly divergent mating behavior, offering a specific evolutionary context.
• Includes analysis of both demographic history and selection footprints, enabling multifaceted evolutionary inference.

Limitations

• Specific data dimensions (rows, columns, file formats) and sample data are unavailable, hindering immediate technical assessment.
• The dataset scope is confined to two Gryllus species, limiting broader taxonomic comparisons.
• As a static research output, the data reflects a specific analysis timepoint and may not be updated.
