EukBank 18S V4: Global Eukaryote Metabarcoding Samples

12,672 globally distributed metabarcoding samples from various biomes constitute this dataset. It contains 335,662 Amplicon Sequence Variants (ASVs) identified from eukaryotic organisms. The dataset was released by Cédric Berney of the Centre National de la Recherche Scientifique.

Use Cases

• Analyze eukaryotic biodiversity patterns based on the global distribution of samples across biomes
• Train models for taxonomic classification based on the 335,662 identified Amplicon Sequence Variants (ASVs)
• Study biogeographic distributions of eukaryotes based on the globally distributed sample collection
• Benchmark metabarcoding analysis pipelines using the provided ASV tables

Strengths

• Contains 12,672 samples, providing a substantial base for analysis
• Includes 335,662 identified Amplicon Sequence Variants (ASVs)
• Samples are globally distributed across biomes, offering broad geographic coverage

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Last update date is unknown; freshness unverified
