Figure 4 from: Matern A, Drees C, Hardtle W, von Oheimb G, Assmann T (2011) Historical ecology meets conservation and evolutionary genetics: a secondary contact zone between Carabus violaceus (Coleoptera, Carabidae) populations inhabiting ancient and recent woodlands in north-western Germany. ZooKeys 100: 545-563. https://doi.org/10.3897/zookeys.100.1546

Figure 4 - Maximum width of the aedeagus tip A and the quotient of maximum and minimum width of the aedeagus tip B are plotted for each population. Boxes display 25–75%- quartiles and bars indicate medians. Whiskers show the total range of values without outliers. Outliers are indicated as circles and extreme outliers as diamonds. Numbers of measured individuals per population are shown in brackets. Pie charts show frequencies of elytral sculpture classes "0" (white), "1" (grey), and "2" (black) in each population. Significant differences between populations are indicated by the lines marked with asterisks.
