  1. For Wilcoxon tests (excluding controls), only significantly different treatments are shown. TP and T1 were never different from each other, neither were T2 and T3. TP: diver presence, T1: flash, T2: manipulation, T3: manipulation + flash. Significance level after Holm-Bonferroni corrections: *p < 0.05, **p < 0.01, ***p < 0.001.
