Freshwater Invertebrate DNA Metabarcoding Data from Melbourne, Australia

Supporting materials from a 2026 study on DNA metabarcoding and barcoding of freshwater invertebrates from greater Melbourne, Australia. The dataset includes summary statistics for sequencing reads, denoising, and comparisons between morphological and DNA-based identification. It was authored by Melissa Carew and is available under a CC-BY-4.0 license.

Use Cases

• Benchmarking DNA metabarcoding pipelines based on the provided sequencing and denoising statistics
• Assessing taxonomic detection gaps between morphological and molecular methods based on the 'missed by' comparison tables
• Evaluating sequencing depth for community analysis using the alpha rarefaction plots mentioned
• Developing or validating reference DNA barcode libraries for Australian freshwater invertebrates

Strengths

• Includes multiple facets of a metabarcoding study: raw sequencing stats, processing stats, and identification comparisons.
• Released under a permissive CC-BY-4.0 license for reuse.
• Last updated on 2026-04-14, indicating recent curation.

Limitations

• Row count and specific column definitions are unknown, requiring manual inspection after download.
• The dataset is small at 875.9 KB, suggesting a limited scope or sample size.
• Geographic coverage is specific to greater Melbourne, Australia, which may limit generalizability.
