Short summary
In the subsaline reed wetland of Lake Neusiedl, we found the highest CH4 emissions in summer and via plant-mediated transport in each season. A clear diel cycle of CH4 emission was only identified for plant-mediated transport in summer. The isotopic source signature of CH4 differed between seasons, with the most 13C-depleted signature in fall. Desiccation reduced methanogenic diversity in the sediments and resulted in a marked increase in and dominance of the O2-tolerant Methanomicrobiales.
