Biological invasions.

Abstract

Ecologists study biological invasions by examining the control over the different stages of the invasion process: introduction, establishment, spread and impact. Only a small fraction of introduced species successfully establish; moreover, only a small fraction of these successfully spread and impact native communities. The factors that constrain success at each of these stages are the focus of this paper.
