EGU 2023 was held this year in Vienna, Austria from April 23-28. iEES Paris was strongly represented with the participation of 9 of our team members.
Minerals are widely assumed to protect organic matter (OM) from degradation in the environment, promoting the persistence of carbon in soil and sediments. In this Review, we describe the mechanisms and processes operating at the mineral–organic interface as they relate to OM transformation dynamics.

J.-L. Janeau, IRD research engineer at iEES Paris (FEST and F2ZC teams), is co-organizer of an EGU21 session.
Soil carbon persistence can be understood through the lens of decomposers as a result of functional complexity derived from the interplay between spatial and temporal variation of molecular diversity and composition. For example, co-location alone can determine whether a molecule is decomposed, with rapid changes in moisture leading to transport of organic matter and constraining the fitness of the microbial community, while greater molecular diversity may increase the metabolic demand of, and thus potentially limit, decomposition.
