Most species introductions are not expected to result in invasion, and species that are invasive in one area are frequently not invasive in others. However, cases of introduced organisms that failed to invade are reported ...

Why some non-native plant species invade, and others fail remains an elusive question. Plant invasion success has been associated with specific species traits. Yet, we have limited knowledge of the mechanisms relating these ...

A common explanation for Centaurea solstitialis invasion in California is that it occupies an "empty niche" created by the replacement of native perennial grasses by exotic annual grasses and concomitant increases in soil ...

Exotic species can spread in the environment, act as an invasive, occupy a niche that was of native species before and replace their role. The impacts caused by invasive species on the native ones show in many ways: ...

Biotic resistance has been invoked as a major barrier to woody species invasion, although the role of resident generalist consumers and their interaction with seed availability in a local community has received little ...

Theory predicts that in more stressful environments, positive plant-plant interactions should be more important than negative ones. For instance, in arid and semiarid regions, amelioration of soil drought produced by the ...
