Aquatic plants can function as conduits for methane from sediment to the air. We studied the flux of methane from plots, in two Swedish lakes, dominated by two species (Phragmites australis, Carex rostrata). There were substantial seasonal differences (June to October), mainly tracking air temperature. There were large differences in flux during 24 h sampling, but with no consistent patterns between days. Emissions per m2 were similar for the two species. This suggests a system where CH4 production shapes emissions while species identity, and diurnal patterns, play a smaller role.
