Box-plots of relative capture success among groups of Triturus newts in four ponds in the department Mayenne in the west of France. Shown are the median − wide horizontal line, interquartile range − box, minimum and maximum − narrow horizontal lines and extreme cases − isolated round symbols. Left panel − comparisons for sexes (males over females), with T. cristatus in red, T. marmoratus in blue and interspecies hybrids in purple. Middle panel − comparisons for groups with T. cristatus versus T. marmoratus (red/blue), T. cristatus versus hybrids (red/purple) and T. marmoratus versus hybrids (blue/purple). Right panel − comparisons for life stages with T. cristatus adults versus juveniles. Locality numbers are shown on the top. For results of statistical analyses see text.
