Nematodes as bioindicators to evaluate the edaphic state of a Low Deciduous Forest area in the state of Guerrero, México

The Low Deciduous Forest (LDF) provides several ecosystem services; however, it is the type of vegetation with the greatest anthropogenic impact. Sampling was carried out at 7 sites in an LDF area in recovery, located in the Costa Chica region, in the Guerrero State, Mexico. The main objective was to evaluate the degree of soil disturbance from the analysis of the composition and structure of communities of nematodes present in each of the sites. Bacterivorous nematodes considered as opportunistic organisms were the most abundant in all sites, indicating disturbed soils. The average values of the ecological indices (Maturity Index - IM, Enrichment Index - IE, and Structure Index - SI) were low in most of the sites, confirming the results obtained with the trophic groups.
