Descripción:The study of the populations of micetozoos in agroecosistemas with diverse characteristics and degrees of disturbance by anthropogenic activities is a subject with scarce investigation at world-wide level. In order to study this interaction, we documented the incidence of two groups of micetozoos (mixogastrids and dictyostelids) in two agricultural systems of sugar cane and pineapple in Costa Rica. For each study system we quantify a series of edaphic, chemical and landscape variables. After the analysis, we found that, for both groups, three variables explained 99% of the variability of incidence of these. For the dictyostelids, the variables were percentage of clay, pH and microbial biomass. In the case of mixogastrids, these variables were Manganese, microbial respiration and pH. The previous results indicate a potential medium for the use of micetozoos as environmental indicators, while the effect of the culture systems on the activity of the microorganisms was quantifiable. However, we believe that it is still necessary to define the role of the different variables measured on the dynamics of both groups of microorganisms in order to establish a conclusion with potential application, supported by empirical data.
