Integrating Ecological and Evolutionary Theory of Biological Invasions 93
insights into the relative importance of these factors for different taxa in setting
the stage for introduced species to become invasive.
6.5 Conclusions
Research on biological invasions is at an exciting junction. The vast amount of
empirical research has enabled deductions that move beyond individual case
studies, and the theoretical stage is set for advancement. With this review of
ecological and evolutionary hypotheses to explain invasion, we offer a quantitative
measure for a key aspect of invasiveness – that of ecological change
between the native and introduced range – and an example of how synthesizing
across hypotheses to form a predictive framework can guide future
empirical and theoretical work.
