In the global warming context, adaptive management strategies involve conservation and restoration of inland waters by planning reintroduction macrophytes to substantially mitigate greenhouse gas emissions (GHG). The selection appropriate species is crucial. We studied influence two submerged macrophyte on GHG production, sediment-oxygen microprofiles, microbial community composition under thermal regimes means a microcosm experiment. chose phanerogam Myriophyllum spicatum, more typical meso-eutrophic habitats, charophyte Chara hispida, frequent in oligotrophic belonging much less group, which, moreover, exhibit contrasting functional traits (i.e., roots versus rhizoids). presence both types considerably reduced diurnal diffusive CO2 due their photosynthetic activity compared bare-sediment situations. radial oxygen loss M. spicatum provided aerobic-microaerobic conditions beyond first sediment centimeter, contrast anoxic sediments created C. hispida. As result this, each type determined particular microbiome. Despite dissolved CH4 being greater plants, no statistical differences flux caused or absence plants was found. demonstrated how presence, not, important than (in our case with temperature difference 3 °C) relation emissions. Both species, perennial, provide ecosystem services year-round are strong candidates for aimed at transforming new restored aquatic ecosystems into carbon sinks.
