Coral Triangle Fish Diversity Predicted from Environmental DNA Accumulation Curves

The Coral Triangle region provides the geographic scope for this dataset. It contains modeled Operational Taxonomic Unit (OTU) accumulation curves derived from environmental DNA seawater samples. The data was created by Jean‐Baptiste Juhel and demonstrates a predicted asymptote of 1,531 fish OTUs, closely matching the 1,611 recorded fish species in the region.

Use Cases

• Predict regional fish species diversity based on OTU accumulation curves from eDNA metabarcoding.
• Model the distribution of species richness among fish families using OTU-based asymptotes.
• Assess the completeness of biodiversity surveys in species-rich regions using eDNA sampling.

Strengths

• Modeled OTU accumulation curves predict fish diversity with high accuracy (R² = 0.92).
• The dataset covers the highly biodiverse Coral Triangle region.
• The method provides an alternative to requiring a complete DNA reference database.

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 paperswithcode.
