Data for: Reproductive strategies of native plant populations altered by a plant invasion

Invasive plant transformers substantially change the abiotic environment of invaded ecosystems and thus habitat suitability to resident species. Post-invasion environmental alteration can also modify the selective pressure acting on native plants. Here, I explored whether the decrease in light availability due to an invasion of Heracleum mantegazzianum drives evolution of reproductive strategies of Veronica chamaedrys, a perennial plant combining sexual and clonal reproduction.
Using a common garden experiment with plant material of V. chamaedrys from 23 sites with distinct invasion history and light conditions, I searched for changes in reproductive allocation. I also asked whether evolution of the two modes can be constrained by the genetic trade-off between them. Furthermore, the phenotypic trade-off between the two modes was explored in a field experiment.
I found that invaded populations increased investments in clonal reproduction, a shift that was driven by decreased light availa..., ,
