Genetic Data for Endemic Three-Striped Butterflyfish Across Four Remote Australian Reefs

Parks Australia provides genetic data from a study on the endemic three-striped butterflyfish (Chaetodon tricinctus). The dataset includes mitochondrial and microsatellite DNA analyses from four remote Australian offshore coral reefs: Middleton Reef, Elizabeth Reef, Lord Howe Island, and Norfolk Island. It was last updated on 2026-07-15.

Use Cases

• Assess genetic differentiation and isolation of peripheral populations based on mitochondrial and microsatellite DNA data.
• Estimate contemporary gene flow and self-replenishment rates to model population recovery times.
• Evaluate vulnerability to local extinction for specific reef locations based on genetic isolation and abundance data.

Strengths

• Data covers four distinct geographic locations, enabling spatial analysis of genetic structure.
• Study reports specific self-replenishment estimates, such as 95% for the Norfolk Island population.
• Uses both mitochondrial and nuclear microsatellite DNA markers to distinguish evolutionary versus contemporary gene flow.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the four studied reefs.
