 Zusammenfassung: Eco-evolutionary dynamics have been shown to be important for understanding population and
community stability and their adaptive potential. However, coevolution in the framework of ecoevolutionary
theory has not been addressed directly. Combining experiments with an algal host
and its viral parasite, and mathematical model analyses we show eco-evolutionary dynamics in
antagonistic coevolving populations. The interaction between antagonists initially resulted in arms
race dynamics (ARD) with selective sweeps, causing oscillating host–virus population dynamics.
However, ARD ended and populations stabilised after the evolution of a general resistant host,
whereas a trade-off between host resistance and growth then maintained host diversity over time
(trade-off driven dynamics). Most importantly, our study shows that the interaction between
ecology and evolution had important consequences for the predictability of the mode and tempo
of adaptive change and for the stability and adaptive potential of populations.
