Abalone Gut Microbiota Across Urchin-Barren Habitats with Geochemical Factors

16S rRNA amplicon sequencing characterized the gut microbiota of abalone (Haliotis discus hannai) collected from mild and severe urchin-barren regions along the Korean coast during winter and summer. The dataset, authored by Jae-Won Jo and last updated in May 2026, compares wild and farmed abalones and links microbiota variation to geochemical parameters like suspended particulate matter and chemical oxygen demand. PICRUSt2-based functional predictions suggest differences in carbohydrate and energy metabolism between habitats.

Use Cases

• Modeling seasonal shifts in gut microbiota based on temperature-related geochemical variation described in the study.
• Analyzing associations between microbial taxa (e.g., Vibrio, Propionigenium) and environmental factors like chemical oxygen demand and dissolved oxygen.
• Predicting functional metabolic pathways (e.g., carbon fixation, staurosporine biosynthesis) in microbial communities from different habitat severities.
• Comparing microbial community structure and interactions between wild and farmed abalones in relation to suspended particulate matter.

Strengths

• Data includes comparisons across two seasons (winter and summer) and two habitat severity levels (mild and severe barren).
• Analysis incorporates stepwise negative controls and prevalence-based decontamination for microbiome characterization.
• Links microbiota to multiple measured geochemical parameters, not just temperature.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data is provided in a PDF format (1.6 MB), which may require extraction to access underlying tables.
