F
Among subjects      
Disturbance 2 2.93 27.34 ***
Site (Disturbance) 6 0.083 0.77 ns
Sample (Site (Disturbance)) 27 0.107  
Within subjects      
Year 2 0.18 3.59 *
Year × Disturbance 4 0.35 0.72 ns
Year × Site (Disturbance) 12 0.13 2.65 **
Sample (Year × Site (Disturbance)) 54 0.049  
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.
