Differential impact on soil microbes of allelopathic compounds released by the invasive Acacia dealbata Link

► Acacia naturally-released secondary compounds can alter soil biota. ► Soil bacteria are more sensitive than soil fungi to Acacia allelochemicals. ► The allelochemical effect of Acacia dealbata depends on the studied ecosystem. ► Soil microbiota of climax forests is more resistant to Acacia allelochemicals.
