Table II
Contrasts for the autoregressive (AR) and Markov models, including total initial and effective sample size calculated from each model, F values and significance. Mean cover difference (%) between contrasted treatments with a positive sign indicates that shrub cover was greater after the disturbance denoted with a (+) than the one with a (–) in the contrasts.
| AR model | Markov model | Mean cover difference (%) | |||
|---|---|---|---|---|---|
| F | p-value | F | p-value | ||
| Contrast 1: PF (+) vs. RPF(–) | 893.83 | < 0.001 | 508.99 | < 0.001 | +9.6 |
| Contrast 2: 20 WF (+) vs. 5 WF (–) | 776.53 | < 0.001 | 170.27 | < 0.001 | +13.8 |
| Contrast 3: PF (+) vs. 5 WF (–) | 1377.01 | < 0.001 | 1240.78 | < 0.001 | +6.4 |
| Contrast 4: RPF (+) vs. 5 WF (–) | 81.02 | < 0.001 | 135.30 | < 0.001 | +2.4 |
