The objective of this thesis was to study how sediment microbial communities in Mediterranean rivers used dissolved organic matter at different spatial and temporal scales. Results from the two field studies, showed that the quality and origin of the dissolved organic matter (allochthonous versus autochthonous) and the different hydrological periods (drought versus base flow) highly modified the biofilm functioning and composition. On the other hand, the two laboratory experiments showed that first, the decrease in dissolved oxygen in sediment depth determined the microbial organic matter degradation. And second, results also showed that warming river water increased the heterotrophy of the microbial communities and clearly modified the foo...
