Bacterial Community Data and Analysis Code for Phylogenetic Diversity Study

A collection of data and R analysis scripts supporting a study on how resource richness influences the occurrence of phylogenetically distinct rare species in bacterial communities. The dataset includes files in formats such as CSV, XLSX, TXT, NWK, and R code. It was authored by Yueqing Song and last updated in April 2026.

Use Cases

• Analyze the relationship between resource richness metrics and phylogenetic distinctness scores for rare species using the provided CSV or XLSX data files.
• Reproduce the phylogenetic tree analysis and community composition visualizations from the study using the included NWK tree files and R scripts.
• Apply the provided R code to similar bacterial community datasets to test hypotheses about rare species occurrence and phylogenetic structure.
• Examine the statistical models linking environmental variables to community metrics as detailed in the accompanying PDF and presentation (PPTX) files.

Strengths

• Dataset is 16.3 MB in size, containing multiple file types for comprehensive analysis.
• Includes raw data, analysis scripts (R code), and presentation materials, supporting full reproducibility.
• Published under a permissive CC-BY-4.0 license, allowing for broad reuse and modification.

Limitations

• The exact number of rows, columns, and sample size for the core data tables is unknown.
• As a static research output, the data is not updated and represents a snapshot from the original study.
• The 16.3 MB size indicates a relatively small-scale dataset, potentially limiting the scope of some analyses.
