Pig-Eye Shark Genetic Markers for Population Structure Analysis in Northern Australia

Parks Australia provides genetic data on the pig-eye shark (Carcharhinus amboinensis) from northern Australia. The dataset includes two mitochondrial and two nuclear DNA markers used to examine population structure and phylogeography. The research suggests Pleistocene-era isolation and restricted contemporary gene flow influenced the observed genetic patterns.

Use Cases

• Analyze population genetic structure based on mitochondrial DNA evidence mentioned in the description.
• Investigate potential sex-specific behaviors like female philopatry using the described nuclear markers.
• Model historical population isolation and connection during Pleistocene sea-level changes.
• Assess contemporary gene flow between defined shark populations in northern Australia.

Strengths

• Uses multiple genetic marker types: two mitochondrial and two nuclear DNA markers.
• Focuses on a specific shark species (Carcharhinus amboinensis) in a defined geographic region (northern Australia).
• Dataset is provided by an authoritative source, Parks Australia.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data freshness should be verified; last updated date is 2026-07-16.
