The aims of this study were to: 

i) evaluate possible diel or seasonal pattern in plant mediated CH₄ emission from the different emergent aquatic macrophytes 

ii) test if the different variables: air temperature, light, air pressure, humidity, carbon dioxide  fluxes, wind, lake type, species and biomass, can be factors controlling CH₄ emissions, and

iii) investigate the possibility to create a model for CH₄ emissions.
