Rainfall frequency and soil water availability regulate soil methane and nitrous oxide fluxes from a native forest exposed to elevated carbon dioxide

Free‐air carbon dioxide enrichment (FACE) experiments in terrestrial ecosystems have demonstrated ecological responses of key ecosystem processes to rising atmospheric carbon dioxide (CO 2 ). However, CO 2 fertilization responses in field conditions have seldom included methane (CH 4 ) and nitrous oxide (N 2 O), particularly in natural and mature forests, which are expected to have an important role in climate change mitigation. Herein, we aimed...
