Sampling comments: Soil Sampling: The study was carried out in both elevated areas (EB) and plains (PS). In each area, 5 sampling points of 16 m2 (4 x4 m) were placed.
Macroarthropods Sampling: In July (winter), October (spring) and February (summer) four pitfall traps (11 cm in diameter) were placed in each sampling area (p. 295)
JA: total sampling effort was "600 trampa-día [2 micrositios × 5 áreas/micrositio × 4 trampa/área × 3 estaciones × 5 días/estación = 600 trampa-día]", meaning 300 for this set of samples
