Asparagopsis Phylogeography in Australia Revealing Cryptic Lineages

Five cryptic mitochondrial lineages of the red seaweed Asparagopsis taxiformis have been introduced worldwide. Parks Australia provides this dataset, last updated in July 2026, which compares globally collected mitochondrial cox2-3 intergenic spacer sequences with those from Australian locations and South Korea to identify lineages and cryptic introductions.

Use Cases

• Identify cryptic invasive seaweed lineages based on mitochondrial cox2-3 intergenic spacer sequences.
• Analyze phylogeographic patterns and haplotype separation between western Australian and Great Barrier Reef isolates.
• Support early detection and containment strategies for invasive seaweeds based on genetic and geographic distribution data.

Strengths

• Identifies a potential sixth cryptic mitochondrial lineage of Asparagopsis taxiformis.
• Compares sequences from multiple Australian locations and South Korea with a global collection.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
