Title

Soil respiration in human-modified forests of Eastern Amazonia

Abstract

This dataset includes measurements of soil respiration in 20 plots (250 x 10 m each) in the Brazilian Amazon. Study plots were distributed across a gradient of forest disturbance, including: undisturbed primary forests , logged primary forests, logged-and-burned primary forests, and secondary forests. Data were collected from January 2015 until November 2017. In December 2015, during the El Niño-mediated drought, eight of our study plots were affected by understory fires.

Lineage

We measured total soil respiration in 20 study plots (0.25ha) distributed along a gradient of forest disturbance in Eastern Amazonia: undisturbed primary forests (n = 5), logged primary forests (n = 5), logged-and-burned primary forests (n = 5), and secondary forests (n = 5). Forest disturbance classes were based on both an analysis of canopy disturbance in a chronosequence of satellite images (1988 to 2010) and on field assessments of fire scars, charcoal, and logging debris. In each plot, we installed five PVC collars 50 m apart. Each collar was approximately 7 cm in size and were installed so approximately 2 cm stayed belowground and 5 cm aboveground. Collars had a 10 cm diameter. After installation, all collars were left to ‘settle’ for at least a week before the first measurement. The collar was connected to an infrared gas analyser (EGM5®) to measure the soil CO2 efflux (i.e. soil respiration). Immediately after every soil respiration measurement, both the soil temperature and humidity were measured inside and outside the collar. We also took note on the collar height. Measures were taken every month. After measuring the soil respiration, we also measured the temperature inside and outside the collar, as well as the soil moisture, the latter with the aid of a HydroSense II.
