A global understanding of the process



In the mountains, the storage of organic carbon is favoured by the temperature and moisture conditions of the environment and by the characteristics of the litter. To study the impacts of these different parameters, Lauric Cécillon’s research was conducted on a cold scree in a mid-altitude mountain area, located in the Southern Alps. A true field laboratory, this ecosystem shows highly contrasted micro-climate soil conditions and plants (pine trees, beech groves and fir forest, and an ecotone zone) simulating the long-term impacts of climate warming over a distance of a few hundred metres.

This researcher first focused on the process controlling the build-up of organic matter in the soil. The decomposition process was studied by experiments with litter bags. The mass losses of these litter bags were measured over a lapse of time. The process of aggregation of the organic matter was monitored by the analysis of thin slices of soil and by the physico-chemical description of the particulate organic matter.
