Schematic description of the eco-evolutionary dynamics observed during the selection experiment in pairwise predator–prey communities (a), two predator–one prey communities (b) and four predator–one prey communities (c). In all panels, blue and red solid lines denote for negative and positive effects on species population dynamics, respectively, black dashed lines depict for bacterial defence evolution against given protist predators and pie charts depict relative protist abundances. Pairwise predator–prey and two predator–one prey communities were characterised by both ecological and evolutionary dynamics, while four predator–one prey communities were dominated by ecological dynamics. B, SBW25 P. fluorescens bacterium; protists: TP, T. pyriformis; TV, T. vorax; CP, C. paramecium; AP, A. polyphaga.
