Appendix 2
Parameters and adjusted-R2 for AR models and effective sample size (n′) calculated from both AR and Markov models. All AR models were highly significant (p-value < 0.001). Model parameters significance was indicated by: (***) p < 0.001; (**) p < 0.01; (*) p < 0.05; (n.s.) p > 0.05. Initial sample size (n) was 1000 in all the transects.
