Coral-Associated Bacterial Metagenomes Under Field and Experimental Heat Stress

A 556.9 MB dataset from a study investigating bacterial communities in Porites lutea corals from Luhuitou Reef, Sanya, China. The data includes samples from intertidal and subtidal habitats under field conditions and from a mesocosm heat stress experiment (29°C vs. 33°C for 7 days). It was created by Chuanzhu Bai and published on figshare under a CC-BY-4.0 license.

Use Cases

• Calculate taxonomic and functional niche breadth based on Levins' index mentioned in the description
• Analyze functional redundancy indices of bacterial communities under thermal stress
• Perform differential abundance analysis of bacterial taxa between intertidal and subtidal habitats
• Construct co-occurrence networks to study microbial community interactions
• Correlate in-situ seawater temperature records with metagenomic functional profiles

Strengths

• Includes a 556.9 MB collection of processed metagenomic data files
• Combines field monitoring data from two distinct habitats with controlled experimental heat stress data
• Provides functional annotations against multiple databases (KEGG KO, eggNOG, and COG)
• Includes supplementary environmental data files for in-situ seawater temperature and diurnal range

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the single reef site studied
