the same time, the high production of organic matter combined with the plant's capacity to
limit the diffusion of oxygen from the atmosphere into the water creates favorable conditions
for the production of methane (CH 4). The combination of these mechanisms challenges the
prediction of water hyacinth's net effects on greenhouse gas (GHG) emissions. To unravel
the impact of water hyacinth on GHG fluxes, we performed an extensive fieldwork study …
