    The potential of evolutionary rescue (ER) to prevent population extinctions in deteriorating environments is increasingly being appreciated. However, evidence suggesting that ER underlies the postinvasion persistence of native flora remains scarce. By exploring a native forb’s population density and trait changes along a replicated invasion chronosequence, I found a U-shaped population trajectory that paralleled the evolution of plasticity to shade. Whereas genotypes from intact, more open sites exhibited a shade-tolerance strategy, the reduced light availability at invaded sites selected for a shade-avoidance strategy. These shifts in shade-response strategies were adaptive and secured postinvasion population persistence. The findings suggest that native populations may survive because of adaptive evolutionary changes operating on the same timescale as the invasion-induced stress.
