a) strong frass vs. control 226.83*** vs 46.59 18.96** vs 7.36 163.90*** vs 37.19 9.16* vs 5.37
b) light frass vs. control 64.81*** vs 43.31 9.18* vs 6.14 55.97* vs 40.01 7.51 vs 6.56
TOC = total organic carbon, DOC = dissolved organic carbon, TNb = total nitrogen bounded, DNb = dissolved nitrogen bounded. Level of significance (* = p < 0.05 / ** = p < 0.01 / *** = p < 0.001), indicating differences between the infested vs uninfested (control) site during a) strong frass activity and b) light frass activity
Table 2: Mean concentrations values (mg l-1) of total and dissolved carbon (TOC, DOC) and total and dissolved nitrogen bounded (TNb, DNb) in the throughfall solutions during strong frass activity (3 months: May, June, July) and less frass activity (4 months: April, August, September, October), both compared with mean concentrations of the control site based on the same time frame.
