Soil Respiration Across a Forest Disturbance Gradient in the Brazilian Amazon

20 plots measuring soil respiration across a gradient of forest disturbance in the Brazilian Amazon from January 2015 to November 2017. Data collection captured the impact of an El Niño-mediated drought and understory fires that affected eight plots in December 2015. This dataset supports research on carbon cycling in human-modified tropical forests.

Use Cases

• Modeling soil carbon emissions based on forest disturbance type (undisturbed, logged, logged-and-burned, secondary).
• Assessing the impact of drought and understory fires on soil respiration rates.
• Comparing carbon dynamics between primary and secondary forests in the Amazon.

Strengths

• Contains data from a controlled gradient of four distinct forest disturbance types across 20 plots.
• Captures a specific climatic event, with measurements before, during, and after an El Niño-mediated drought and fire.

Limitations

• Column names and specific measurement variables are not listed in the provided metadata.
• Conflicting metadata: one platform lists a last update date in 2026, while others show no update information.
