Transcriptomic Data for Taildropper Slug Phylogenetics

Transcriptomes for six of the nine described Prophysaon slug species resolve phylogenetic relationships. The 104.7 MB dataset includes VCF and FA files supporting analyses of introgression and undescribed diversity. Megan Smith generated this data to challenge existing morphological classifications.

Use Cases

• Perform phylotranscriptomic analysis using VCF files to resolve Prophysaon species relationships.
• Detect introgression signals within the Prophysaon genus from transcriptomic sequence alignments.
• Investigate undescribed diversity within the P. andersonii—P. foliolatum species complex using molecular data.
• Conduct geometric morphometrics analyses in conjunction with transcriptomic data to study phenotypic diversity.

Strengths

• Data covers six of the nine accepted Prophysaon species, providing broad taxonomic representation.
• Includes multiple file formats (VCF, FA) suitable for different bioinformatic analyses.
• Generated from transcriptomes, offering gene-level resolution for phylogenetic inference.

Limitations

• Sample data and column structure are unavailable, complicating initial data exploration.
• Transcriptomes are only available for six species, missing three described Prophysaon species.
• The dataset's specific row count and feature dimensions are unknown.
