Table 1: Pearson coefficient of correlation (r) between BT and UT catches per sampling date, calculated for all sites together and each experimental site. \(p\) value and number of observations (N) are also reported. Values of r in bold are significant at \(p\) < 0.05. \begin{table}

For male and female catches, regression did not select any significant variable. The index X of the spatial association of male and female distribution was statistically significant in most cases (Table 3). In Spain and Tunisia, X was significant for all sampling weeks; in Italy in all but 1 week; in Lebanon, 3 weeks were not significant; in Greece, 4 weeks out of 9 were significant. Maps of total catches showed, in general, a prevalence of positive spatial association among male and female distributions. In Greece, with low population levels, the highest hot spot, coinciding for males and females, corresponded to UTs. The areas of positive association are widespread but did not include BTs. Negative associations were observed that also included two BTs (Figure 5). Figure 4: Linear relation between the aggregation index _Ia_ and catches of adults obtained from BTs, the only independent variable with a significant effect on _Ia_. The 95% confidence lines are represented around the regression line. Boxplots for each axis visually summarise data as follows: the blue box represents the interquartile range (IQR), with the bottom of the box at Q1, the top at Q3, and a line within the box at the median; lines extending from the box represent the minimum and maximum values within 1.5 times the IQR; transparent points are outliers that fall outside the lines.
