Three factors influence exotic performance
Below we introduce the three component factors that collectively
influence exotic performance in the context of the ERH. We first define
each of the factors and outline their importance, before specifying ways
in which they can be measured. Not every aspect of our framework will be
applicable in every case. However, the framework provides a general
outline for the way the ERH may apply to invasion, and what factors
determine its role in exotic establishment, naturalisation, and
invasiveness.
