FIGURE 2 Scatterplots of the average (a, b), species-specific (c, d) and phylogenetic (e, f) components of the average colour lightness and body volume of (all habitats = 518, lentic = 337, lotic = 181) assemblages of European odonates and z-standardised annual mean temperature, and annual precipitation. The colour of the dots indicates the habitat type of the assemblages. Lines indicate regression lines of ordinary least squares models. The colour lightness ranges from 0 (absolute black) to 255 (pure white). The P - component represents the phylogenetically predicted part of the trait and S - component represents the respective deviation of the average trait from the P - component.
