Table 3. Results of the niche overlap analysis. For each niche axis, we analysed niche overlap patterns for both patch-level assemblages (species with same signs on the first compromise axis, but see Table 2) and plot-assemblages (species present in a given plot). ‘Lower tail’ and ‘Upper tail’ indicate the number of assemblages for which the observed Pianka Oik was respectively less than or greater than predicted by the null model. The number in parentheses indicates the number of assemblages with significant patterns (P < 0.05, one-tailed test). Different letters indicate significant differences between observed and EBC averages (P < 0.05, one-way ANOVA). The P values indicate the probability of accepting the null hypothesis that the standardized effect size (SES) differed from zero, and the P∗ values the probability of having no significant difference between SES calculated for patch-level and plot-assemblages (one-way ANOVA).
