Predicting which nonnative species become invasive is critical for their successful
management, and Charles Darwin provided predictions based on species' relatedness …

Darwin proposed two seemingly contradictory hypotheses regarding factors influencing the
outcome of biological invasions. He initially posited that nonnative species closely related to …

Darwin acknowledged contrasting, plausible arguments for how species invasions are
influenced by phylogenetic relatedness to the native community. These contrasting …

The degree to which biotic interactions influence invasion by non-indigenous species may
be partly explained by the evolutionary relationship of these invaders with natives. Darwin's …

Concerns over the ecological impacts of invasive alien plant species have generated great
research interest in understanding the mechanisms that underlie the capacity of such plants …

We provide a brief overview of progress in our understanding of introduced plant species. 2.
Three main conclusions emerge from our review:(i) Many lines of research, including the …

Despite intensive research, we still have no general understanding of why plant invasions
occur. Many different mechanisms of plant invasions have been proposed, but studies …

Introduced plant populations lose interactions with enemies, mutualists and competitors from
their native ranges, and gain interactions with new species, under new abiotic conditions …

Darwin's naturalization hypothesis predicts that introduced species tend not to invade areas
containing congeneric native species, because they would otherwise compete with their …

Two venerable hypotheses, widely cited as explanations for either the success or failure of
introduced species in recipient communities, are the natural enemies hypothesis and the …
