The proportional contribution of R H to R S was reduced to an average of 59% by nitrogen addition, although this reduction was of marginal significance (p = 0.051, Table S4 ) due to high variability in f RH .

The inclusion of a warming by measurement year interaction for R 10 resulted in small (0.02 μmol m −2 s −1 ) and marginally significant decrease in R 10 during the second year of warming (p = 0.065, Table S7 ).
