Cytogenetic data, including karyotypes and gene positions, for approximately one hundred species of Antarctic teleost fish. The dataset includes multiple specimens per species, with some referenced in the national collections of the French National Museum of Natural History (MNHN). It was contributed by the organization SCIOPS and hosted on NASA Earthdata.
Use Cases
- Analyze chromosome_formulas across species to study karyotype evolution in Antarctic teleosts.
- Compare relative_gene_positions to identify conserved syntenic blocks or chromosomal rearrangements.
- Use species and specimen identifiers to correlate cytogenetic data with physical specimens in the MNHN collections.
- Investigate intraspecific variation by examining data from multiple_specimens per species.
Strengths
- Covers approximately one hundred species, providing a broad taxonomic scope.
- Includes multiple specimens per species, allowing for assessment of individual variation.
- Specimens are linked to a authoritative national collection (MNHN), enhancing traceability.
Limitations
- The exact sample size (row count) and number of data features per record are unknown.
- Data is focused solely on Antarctic species, limiting geographic generalizability.
- The recency of data collection and updates is unspecified, which may affect relevance.
