Circadian release of methane from Amazon hydroreservoirs

摘要

The identification of key aspects of the biogeochem-istry of methane in natural and artificial lakes has notably increased during the last two decades. For instance, the metabolic pathways of methanogenesis were accurately revealed by isotopic analysis (Sugi-moto & Wada 1995). From empirical methane fluxes and isotopic data acquired in Amazon manmade lakes, this article presents new concerns on the emission dynamics induced by natural circadian rhythms.
