Enemy release and evolution of increased competitive ability: at last, a smoking gun!
Evolution by natural selection can sometimes be very rapid and therefore relevant for many ecological questions (Schoener, 2011). One area of ecology where this appears to be particularly true is biological invasions, probably because species introductions often involve major changes in biotic interactions and thus novel environments with different selective forces than in the species’ native r...
متن کاملThe evolution of increased competitive ability, innate competitive advantages, and novel biochemical weapons act in concert for a tropical invader.
There are many non-mutually exclusive mechanisms for exotic invasions but few studies have concurrently tested more than one hypothesis for the same species. Here, we tested the evolution of increased competitive ability (EICA) hypothesis in two common garden experiments in which Chromolaena odorata plants originating from native and nonnative ranges were grown in competition with natives from ...
متن کاملTesting the evolution of increased competitive ability (EICA) hypothesis in a novel framework.
The "evolution of increased competitive ability" (EICA) hypothesis proposes that escape from natural enemies, e.g., after transcontinental introductions, alters the selection regime because costly defenses no longer enhance fitness. Such an evolutionary loss of defenses enables resources to be directed toward growth or other traits improving performance. We tested the EICA hypothesis in a novel...

متن کاملEco‐immunology and bioinvasion: revisiting the evolution of increased competitive ability hypotheses
Immunity is at the core of major theories related to invasion biology. Among them, the evolution of increased competitive ability (EICA) and EICA-refined hypotheses have been used as a reference work. They postulate that the release from pathogens often experienced during invasion should favour a reallocation of resources from (costly) immune defences to beneficial life-history traits associate...
