Integrating novel chemical weapons and evolutionarily increased competitive ability in success of a tropical invader

The evolution of increased competitive ability (EICA) hypothesis and the novel weapons
hypothesis (NWH) are two non‐mutually exclusive mechanisms for exotic plant invasions,
but few studies have simultaneously tested these hypotheses. Here we aimed to integrate
them in the context of Chromolaena odorata invasion. We conducted two common garden
experiments in order to test the EICA hypothesis, and two laboratory experiments in order to
test the NWH. In common conditions, C. odorata plants from the nonnative range were better …
