【 摘 要 】

The abundance and diversity of macroinvertebrates are closely related, among other features, with the nutrient content of the soil. In order to analyse this relationship under agroforestry arrangements of the Colombian Andean Amazon (Caquetá), a completely random plot design with three repetitions was used, being the treatment of the agroforestry arrangements: AB = Abarco (Cariniana pyriformis Miers); CH = Caucho (Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg.); PA = Paricá (Schizolobium amazonicum Huber); y HU = Huito (Genipa Americana L.). In each arrangement monoliths of 25 x 25 x 30 cm of depth according ISO 23611-5 to quantify the macrofauna and soil samples for physical-chemical characterization were taken. The relationship among edaphic properties and the macrofauna in the different agroforestry arrangements was determined by a Co-inertia analysis. The highest abundance of macrofauna was found in the AB arrangement (945 ± 382 individuals/m2) and the minimum 487 ± 80 (individuals /m2). The total richness was 13 taxa, being the PA arrangement the one with the highest richness (6.6 ± 0.8) and the AB arrangement with the lowest richness (4.8 ± 0.8). A significant correlation (Co-inertia analysis: RV = 0.13, P <0.05, Monte Carlo test) was observed, this proved the response of the macrofauna to the properties of the soil. Specifically, a negative effect of aluminium on the abundance of Coleoptera was found, as well as some positive relationships between organic carbon and the abundance of earthworms and phosphorus with the abundance of termites.
