Ribosomal RNA Counts from Sea Urchin Embryo and Larval Metagenomes

Per-offspring ribosomal RNA gene counts (16S and 18S) derived from the metagenome of the sea urchin species Arbacia lixula. The dataset was created by Tyler J. Carrier and last updated on April 23, 2026. Values were normalized by dividing by 200.

Use Cases

• Compare microbial community composition between developmental stages based on 16S and 18S rRNA gene counts.
• Analyze per-offspring variation in ribosomal RNA abundance within a metagenomic context.
• Benchmark normalization methods for metagenomic data from pooled embryo and larval samples.

Strengths

• Data is openly licensed under CC-BY-4.0.
• The description specifies a clear normalization method (division by 200).
• The dataset focuses on a specific model organism (Arbacia lixula) and life stages.

Limitations

• The dataset is very small at 11.9 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
