The paper provides a compelling argument for the theory which has broadened my understanding of the interaction between an invasive species and the ecosystem. While no direct experimental results were presented, the theory seems intuitive enough that it warrants consideration in invasive species analysis. I would have preferred to see more observational examples of the concept in action to illustrate that facilitation is more than a minor impact in the overall equation.
