Purpose: Despite the increasing number of studies investigating tree methane fluxes, the relationships between tree methane fluxes and species traits remain mostly unexplored. We measured leaf and stem methane fluxes of five tree species (Acer saccharinum, Fraxinus nigra, Ulmus americana, Salix nigra, and Populus spp.) in the floodplain of Lake St-Pierre (Québec) and examined how these fluxes vary with species traits (wood density, humidity, pH; leaf water content, pH, stomatal conductance; methanogen and methanotroph relative abundances (RAs) in leaf, wood, and bark).
Abstract: We measured leaf and stem methane fluxes of five tree species in the floodplain of Lake St-Pierre using the Licor Li-7810. Measurements were made in 6 blocks each divided in a 'high flood frequency' and a 'low flood frequency' plot in July 2023, October 2023 and July 2024. We also measured different environmental parameters (Soil humidity, temperature and conductivity; irradiance) and tree traits (tree diameter, wood and bark density, humidity and pH, leaf humidity, pH and stomatal conductance).
