Resumen
In the Orinoco sub-region, commercial forestry is a promising socio-economic opportunity that contributes to reducing the existing pressure on natural forests. However, documenting the role of afforestation in conserving soil biodiversity as an input to promote sustainable forest management and its associated diversity is scarce. For this reason, in this study, we evaluated the co-occurrence of predatory ants with termites and springtails based on changes in their abundance to better explain the assemblages observed in different land uses and two contrasting climatic seasons. For this purpose, samples of ants, termites, and springtails were collected from 2, 6, 8, and 14-year-old Eucalyptus pellita plantations, pastures, and gallery forest remnants in November 2014 and May 2015. Specimens were processed and identified at the Universidad Distrital Francisco José de Caldas Forest Health Laboratory. The co-occurrence analysis between predatory ants with termites and with springtails compared the relative abundances of each group (ants, termites, and springtails) for each cover and contrasting climatic season. A positive correlation between the abundance of termites, springtails and predatory ants occurred in plantations, gallery forests, and pastures. Besides the influence of vegetation coverage, the climatic season also affected the assemblages of ants, termites, and springtails. Also, dominant ant species are generalists and respond seasonally to the supply of termites and springtails in the different coverages. Therefore, it is presumed that the spatial and temporal co-occurrence among the groups analyzed does not necessarily indicate predatory interactions between ants and their potential prey, termites, and springtails.
