Temporal phenotypic response of Paramecium aurelia (a–c) and Spirostomum teres (d–f) during the selection phase. Trait values at the start (day 4) and end (day 78) of the selection phase for biomass, quantified as bio-area (a,d), cell shape, quantified as cell size ratio between the major and minor cell axis (b,e), and dispersal ability, quantified as gross speed (c,f) when P. aurelia and S. teres evolved in the absence (blue colors) and presence (orange colors) of competing species along different salinity conditions (indicated by different shades, from light to dark color intensity corresponding to 0, 0.5, 1, 2 and 4 g/l). Dots represent mean trait values of each replicate with error bars showing the standard deviation and representing the phenotypic trait distribution. The slope of the line connecting dots shows the temporal shift in the trait considered. Dots are horizontally jittered for visual aid. Temporal phenotypic differences are shown in Supplementary Figure S1. Supplementary Tables S1 and S2 show the detailed results of the statistical analysis.
