Among subjects      
Disturbance 2 12.4 23.70***
Site (Disturbance) 6 0.35 0.67 ns
Sample (Site (Disturbance)) 27 0.52
Within subjects      
Year 2 1.72 8.52**
Year × Disturbance 4 0.262 1.30 ns
Year × Site (Disturbance) 12 0.723 3.58**
Sample (Year × Site (Disturbance)) 54 0.202  
Note: Repeated measures are on year. For the within-subject tests, the significance of F was determined for adjusted degrees of freedom, which equal the df multiplied by Huynh–Feldt epsilon, (0.73533).

* P < 0.05; ** P < 0.01; *** P < 0.001; ns, not significant.
