Structural equation models depicting casual paths of uppermost forest soil layers C stocks (forest floor and mineral soil). Showed links were significant at p < 0.05 (solid line) or marginally significant at 0.05 < p < 0.10 (dashed line). Arrow width is proportional to standardized path coefficients (showed beside arrows). R 2 is showed beneath the variable names. Structural equation models were calculated using data from the three experimental plots
