Description :
Focusing on pyrogenic organic matter (PyOM), the AA. investigated an altitudinal soil sequence on Mount Etna, Italy, ranging from 500 m to 1800 m asl, where the fire frequency is assumed to have been higher at lower elevations due to a warmer and drier climate. They evaluated the effect of fire on the chemical and physical characteristics of SOM along the altitudinal sequence. At 2 sites at a similar altitude but having a different recent fire history, they also examined the effect of fire frequency on SOM. It is shown that fire is an important but not the only factor controlling SOM dynamics.
