We review and synthesize recent developments in the study of the invasion of
communities in heterogeneous environments, considering both the invasibility of the
community and impacts to the community. We consider both empirical and theoretical
studies. For each of three major kinds of environmental heterogeneity (temporal, spatial
and invader-driven), we find evidence that heterogeneity is critical to the invasibility of
the community, the rate of spread, and the impacts on the community following
invasion. We propose an environmental heterogeneity hypothesis of invasions, whereby
heterogeneity both increases invasion success and reduces the impact to native species in
the community, because it promotes invasion and coexistence mechanisms that are not
possible in homogeneous environments. This hypothesis could help to explain recent
findings that diversity is often increased as a result of biological invasions. It could also
explain the scale dependence of the diversityinvasibility relationship. Despite the
undoubted importance of heterogeneity to the invasion of communities, it has been
studied remarkably little and new research is needed that simultaneously considers
invasion, environmental heterogeneity and community characteristics. As a young field,
there is an unrivalled opportunity for theoreticians and experimenters to work together
to build a tractable theory informed by data.
