PREBacteria_GRL_Dataset

PREBacteria_GRL_Dataset contains environmental DNA data on bacterioplankton communities from the lower Pearl River, its estuary, and adjacent coastal waters. The dataset, created by Fu Lei and last updated on 2026-04-21, is 606.8 KB in size and available in XLSX and GEPHI formats under a CC-BY-4.0 license. It investigates microbial community structure, diversity, and network robustness across a salinity continuum.

Use Cases

• Modeling the relationship between salinity and microbial taxonomic/phylogenetic diversity based on the described gradient.
• Analyzing network robustness and stability in microbial communities across different aquatic zones.
• Investigating deterministic versus stochastic processes in microbial community assembly along an environmental continuum.
• Identifying core taxa shifts and the replacement of freshwater clades with salt-tolerant groups.

Strengths

• Dataset includes data from three distinct aquatic zones: river, estuary, and coastal waters, enabling comparative analysis.
• Data is available in both tabular (XLSX) and network graph (GEPHI) formats, supporting different analytical approaches.
• Explicitly investigates and provides a framework for diversity-stability decoupling in microbial communities.

Limitations

• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset's 606.8 KB size indicates a limited scope, potentially representing a specific snapshot or subset of observations.
