Other claims from this paper (6)
- Observation Plants from introduced populations had a significantly lower reproductive output.
- Observation Plants from introduced populations allocated more biomass to roots.
- Observation Plants from introduced populations were more tolerant to a generalist insect herbivore.
- Intervention effect Introduced populations showed greater plasticity in response to fertilization.
- Observation Introduced populations were phenotypically most similar to a subset of native populations from mountainous regions in southern Africa.
- Mechanism The invasion success of Senecio inaequidens in Central Europe is suggested to rest on selective introduction of preadapted and plastic genotypes rather than on adaptive evolution in the introduced range.
