Oxidation rates (mean s.d.; n = 4) measured during soil incubations before and after C addition from soils collected at Kilpisjrvi. Differences between control and C-addition treatments (two-tailed) were determined with Dunn's test and unadjusted P values are significant at * P 0.05 and ** P 0.01. Exact P values are indicated in the figure. Carbon was added as glucose and measurements took place before C addition (control), within 1 h after C addition, as well as 24 h after C addition. DW, dry weight.
