Community Similarity Matrix for Species with Low Floating Viability

A 6.7 KB CSV file contains a community similarity matrix calculated using the Sørensen similarity index. The dataset, authored by Seokmin Kim and last updated on 2026-05-27, focuses on species with a floating viability time of less than 7 days. It is shared under a CC-BY-4.0 license on the figshare platform.

Use Cases

• Compare ecological communities based on species composition similarity.
• Analyze the relationship between species traits, such as floating viability, and community structure.
• Validate community ecology models using empirical similarity indices.
• Benchmark clustering or classification algorithms for ecological community data.

Strengths

• Dataset is small (6.7 KB), facilitating quick download and inspection.
• The specific similarity metric (Sørensen index) and filtering criterion (95th percentile viability < 7 days) are clearly defined.

Limitations

• Row and column counts are unknown, making it difficult to assess the dataset's scale.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality requires manual inspection.
