Insights into the mechanism of diurnal variations in methane emission from the stem surfaces of Alnus japonica

The greenhouse gas methane, or CH4 is produced in certain tree species, but how these mechanisms actually work is a matter of volatile debate, particularly with regard to the diffusive transport of CH4 gas through the trees.
