The differences between ecological data among the four states
sampled in the study area were tested by means of a one-way
ANOVA. When the factor ‘state’ was significant, we applied Student
Tukey-HSD post-hoc tests to perform pairwise comparisons of
means among the different trajectories. For those variables not
normally distributed, we used the KruskaleWallis non parametric
ANOVA test. We performed all statistical analyses with Statistica
version 6.0.
