Marine Algal Flora of Santa Maria Island, Azores with 261 Taxa

2329 specimens belonging to 261 macroalgal taxa were collected from the littoral and sublittoral zones around Santa Maria Island. The inventory, led by Ana I. Neto from Universidade dos Açores, includes 152 Rhodophyta, 43 Chlorophyta, and 66 Ochrophyta, with 52 new records for the island. This work improves knowledge of the Azorean macroalgal flora at local and regional scales.

Use Cases

• Analyzing macroalgal biodiversity and species composition based on the 261 registered taxa.
• Studying species introductions and endemic distributions based on the 11 introduced and 2 Macaronesian endemic species listed.
• Modeling species ecology and occurrence patterns around the island based on the provided presence data and collection depths.
• Comparing algal flora across remote oceanic islands based on the described cosmopolitan nature of the Azores archipelago.

Strengths

• Contains 2329 specimens providing a substantial basis for analysis.
• Registers 261 distinct macroalgal taxa with detailed breakdowns by phylum (152 Rhodophyta, 43 Chlorophyta, 66 Ochrophyta).
• Includes 52 new records for Santa Maria Island, expanding the known flora.
• Data collection covered an area of approximately 64 km and depths down to 40 m, suggesting thorough spatial coverage.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
