Mean values (± e.s.) of (a) Cfung/Cmic, (b) microbial respiration, (c) hydrolase activity (HA), (d) dehydrogenase activity (DHA) measured before (BF) and after fire (AF) in soils collected on the Vesuvius National Park, Southern Italy. The asterisks indicate significant differences (t-test—*: p < 0.05, **: p < 0.01, ***: p < 0.001) in soil properties between BF and AF soils.
