Soil biological activity and macroinvertebrate diversity are key indicators of ecosystem function in tropical landscapes. This study evaluates the effects different land-use systems—Amazonian Chakra agroforestry (timber-based fruit-based), cocoa monoculture, rainforest—on soil microbial respiration, enzymatic activity, Ecuadorian Amazon. Forest soils exhibited highest edaphic respiration (240 ± 64.3 mg CO2 m2 ha−1, p = 0.034), while systems maintained intermediate surpassing monocultures function. The organic matter (SOM) content at a 10 cm depth was significantly higher (19.8 3.88%) than forest (p 0.006); however, showed greater functional responses systems. relationship between recorded (REC_CO2) basal (RBC_CO2) non-linear trend, as revealed by LOWESS smoothing, suggesting that dynamics influenced substrate availability thresholds beyond simple linear predictions. These findings underscore potential sustainable strategy enhances biodiversity, carbon sequestration nutrient cycling. Implementing optimized practices can contribute to long-term conservation resilience agroecosystems.
