Effects of wildfire and laboratory heating on soil aggregate stability of pine forests in Galicia: The role of lithology, soil organic matter content and water repellency

► Wildfire-induced changes in aggregate stability are highly variable. ► Changes in aggregate stability are associated with changes in organic carbon content. ► Changes in aggregate stability can also be explained well by changes in water repellency. ► Fire severity is a key explanatory variable and should be estimated in future field studies.
