Statistical analysis conducted through Wilcoxon signed-rank test. Statistically significant data are in bold. N, number of individuals included in each category – It does not reflect the number of individuals included in the performed experiments. Data are presented in table as: number of individuals; mean ± standard deviation; median (minimum to maximum), except for the first line where the absolute value is shown
