Pig-Eye Shark Genetic Markers for Phylogeography in Northern Australia

A 2026 dataset from Parks Australia provides genetic data on the pig-eye shark (Carcharhinus amboinensis). It includes two mitochondrial and two nuclear DNA markers used to examine population structure and phylogeography in northern Australia. The research explores historical isolation during the Pleistocene and contemporary restricted gene flow.

Use Cases

• Analyzing population genetic structure based on mitochondrial DNA markers mentioned in the description
• Investigating sex-specific behaviors like female philopatry using nuclear genetic markers
• Modeling historical population isolation and connection during Pleistocene sea-level changes
• Studying contemporary restricted gene flow in coastal shark populations

Strengths

• Includes four distinct genetic marker types: two mitochondrial (control region, NADH hydrogenase 4) and two nuclear (microsatellite, Rag 1)
• Focuses on a specific shark species (Carcharhinus amboinensis) in a defined geographic region (northern Australia)
• Research context integrates both historical (Pleistocene) and contemporary ecological factors

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is provided as HTML, which may require parsing to extract structured data
