Abstract

HERNANDEZ-TIRADO, Arturo E. et al. Edaphic arthropods in different land use forms at Sierra Nevada, Tepetlaoxtoc, Estado de México, Mexico. Rev. Colomb. Entomol. [online]. 2022, vol.48, n.1, e11632.  Epub May 21, 2022. ISSN 0120-0488.  https://doi.org/10.25100/socolen.v48i1.11632.

The objective of this study was to describe the diversity and abundance of edaphic microarthropods in relation to the physical and chemical characteristics of soils under different use and management and to characterize their structure in an area of stone mining or quarrying. For this purpose, edaphic microarthopods assemblages were studied in five zones with different land use: Conserved Pine-Oak forest (B), Degraded Pine-Oak forest (Z), Agricultural (V), Erosion (E), Mine (M), in Sierra Nevada (Tepetlaoxtoc, Mexico), in order to know their relationship with both physical and chemical parameters, and also their potential as bioindicators, using the values of the QBS-ar index, in stony mining areas. A positive and significant relationship was found with the abundance and moisture and organic matter percentages. Groups described as bioindicators, hyperparasitoids and predators were identified in sites with more conservation than those with greater degradation. The QBS-ar index values were higher in the area B. Three zones, B, M and E, were identified, according by their suitability for ecological rehabilitation action. The potential of soil microarthropods to be integrated into management programs and conservation and rehabilitation strategies in areas of stone mining was recognized.
