Plant phenology and species‐specific traits control plant CH 4 emissions in a northern boreal fen
Summary Aerenchymatic transport is an important mechanism through which plants affect methane (CH 4 ) emissions from peatlands. Controlling environmental factors and the effects of plant phenology remain, however, uncertain. We identified factors controlling seasonal CH 4 flux rate and investigated...

Summary Aerenchymatic transport is an important mechanism through which plants affect methane (CH 4 ) emissions from peatlands.

We measured CH 4 fluxes through individual shoots of Carex rostrata , Menyanthes trifoliata , Betula nana and Salix lapponum throughout growing seasons in 2020 and 2021 and Equisetum fluviatile and Comarum palustre in high summer 2021 along with water‐table level, peat temperature and porewater CH 4 concentration.
