Abstract

Rates of nitrogen (N) fixation with nodules of Alnus viridis subsp. fruticosa (alder) were measured at the Kougarok hillslope site in July of 2017 and 2018. Rates were calculated following incubation of excised nodules with 15N labeled N2 gas, as described in Anderson et al. (2004). Alder GPS coordinates, height and basal area were also recorded.
