Land use change (LUC) has important effects on the aboveground biota, mainly by altering richness and diversity, as well as ecosystem functioning. However, the effects of LUC on abiotic and biotic soil properties need to be assessed to determine recovery potential when the original vegetation is restored. The Los Tuxtlas tropical rain forest landscape in Veracruz, Mexico, offers a suitable framework for testing this. To assess the effect of LUC on the microbial community of this tropical rain forest landscape, we analyzed the whole-cell fatty acid profile of the microbial community and physicochemical properties of soils from four types of land use: crops, pastures, secondary forest, and primary tropical rain forest for the dry and rainy seasons. Regardless of season, the microbial data grouped according to land use. The composition of the microbial community was correlated with soil pH in the dry season, and …
