PREMISE OF THE STUDY:
Invasive plant species are typically thought to pose a large threat to native biodiversity, and local-scale studies typically confirm this view. However, plant invaders rarely cause regional extirpations or global extinctions, causing some to suggest that invasive species' influence on native biodiversity may not be so dire. We aim to synthesize the seemingly conflicting literature in plant invasion biology by evaluating the effects of invasive plant species across spatial scales.
METHODS:
We first conducted a meta-analysis on the effects of invasive plants on the species richness of invaded communities across a range of spatial extents. We …
