Post-Fire Soil Bacterial Communities in a Pine-Oak Forest of Northeastern Mexico

Sandra E. Rivas-Morales investigated wildfire-associated patterns in soil bacterial communities across a pine–oak forest in northeastern Mexico. The dataset likely contains taxonomic and physicochemical data from 16 soil samples categorized into three time-since-fire classes: early (<3 years), intermediate (3–10 years), and late (>10 years). The data was last updated on April 29, 2026.

Use Cases

• Analyze shifts in bacterial community composition based on time-since-fire categories mentioned in the description
• Identify bacterial taxa with thermotolerant or pollutant-degrading traits based on relative abundance data
• Compare co-occurrence network structures between burned and unburned soil communities
• Correlate bacterial taxa with soil physicochemical properties like pH, moisture, and organic matter

Strengths

• Includes 16 soil samples representing a chronosequence of three distinct post-fire time classes
• Contains measurements of soil physicochemical properties including pH, moisture, texture, organic matter, and salinity
• Identifies specific bacterial genera of interest, such as Massilia, Arthrobacter, and Blastococcus

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is very small (28.9 KB), indicating limited scope
