Soil Microbial Community of Mediterranean Shrubland after a fire event

The aim of this study was to evaluate the effect of UV-B and UV-A radiation on soil bacterial richness, abundance and community composition in a Lithic Dystroxerept of a Mediterranean shrubland and to determine whether these effects depend on reduced rainfall and/or soil physicochemical properties. Soil samples (0-5 cm) were collected from 18 plots of 9 m2 subjected to long-term UV conditions: UV-A + UV-B exclusion (UV0 plots), UV-B exclusion (UVA plots), or ambient UV-A + UV-B exposure (UVAB plots), combined with two rainfall regimes: natural (NR) or reduced (RR) rainfall.
