Benthic Macroalgae Community Structure in the Shengsi Archipelago, East China Sea, 2025

May 2025 survey data of benthic macroalgal communities from 30 intertidal stations in the Shengsi Archipelago, East China Sea. The dataset records 43 species, biomass, abundance, and diversity indices, and includes comparisons with historical data from 2010. It was authored by Lingling Wang and shared under a CC-BY-4.0 license.

Use Cases

• Analyze spatial patterns of macroalgal biomass and diversity based on the described 'west–low, east–high' gradient.
• Model the relationship between environmental heterogeneity and phylogenetic clustering (Δ+) based on the calculated indices.
• Assess long-term community shifts and functional-group dominance changes based on the comparison with historical data from 2010.
• Investigate the compensatory role of mussel aquaculture on macroalgal diversity based on the described association with high diversity in aquaculture zones.

Strengths

• Includes comparisons with historical data, enabling analysis of long-term trends since 2010.
• Covers 30 spatially distinct intertidal stations across environmentally different zones.
• Quantifies multiple community attributes: 43 species, biomass, abundance, α-diversity, and taxonomic distinctness.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Spatial coverage is limited to a single archipelago region surveyed in one month (May 2025).
