a N deposition-dependent responses; b organic horizon soil C/N-dependent responses; c mineral horizon soil C/N-dependent responses. Colored lines represent the N deposition- and soil C/N-specific responses, with their bootstrapped 95% confidence intervals shaded in the corresponding color. N deposition and soil C/N were analyzed as continuous variables but illustrated here based on the meaningful three levels of breakpoints (mean, mean plus and minus standard deviation (SD)). The significance (P) is reported for each term tested, with P values calculated using a one-sided F test. ND: decadal cumulative of N deposition (for each plot), df: degrees of freedom.
