Genomic and molecular data from a study of cumacean crustaceans in Antarctica. The project generated sequenced genomes from 8 species, about 250 transcriptomes from about 70 species, and approximately 470 COI and 16S amplicon barcodes from about 100 species. Research was conducted by the AMD_USAPDC organization, with data last updated in July 2026.
Use Cases
- Analyze gene gain/loss and positive selection from genomic sequences to understand cold adaptation.
- Construct a phylogenetic framework for Antarctic Cumacea using transcriptome and genome data from ~70 species.
- Compare rates and timing of diversification across species using curated morphological reference collections.
- Identify genes with significant differential expression as a function of adaptation to Antarctic habitats.
Strengths
- Includes sequenced genomes from 8 distinct cumacean species.
- Provides approximately 470 COI and 16S amplicon barcodes from about 100 species for diversity analysis.
- Generates about 250 transcriptomes from about 70 species for comparative genomics.
Limitations
- Sample size for full genomes is limited to 8 species.
- Geographic scope is restricted to Antarctic regions, limiting broader biogeographic conclusions.
- Specific row counts, file formats, and data structure details are unknown.
