Land uses changes due to anthropogenic activities put in danger the natural ecosystems and the services they provide, allowing for biological invasions. We evaluated litter decomposition of dominant species and common litter, soil respiration, and nutrient turnover in plots that were sown by different plant assemblages and that represented different successional stages (early, intermediate, and late successional species, including native and exotic species). Litter decomposition of the dominant species significantly (P
