A competitive network theory of species diversity

That the most probable outcome is the coexistence of a large number of species. What more do you need to know? As in systems of culture, laws, ethnicity, species and probably many others, complexity is either maintained or increased over time. What I would like to know is: “what size perturbation is required to break the equilibrium and return this system to a homogeneous (or at least distinctly different) state.” Isn’t it also well-established that state evolution in complex systems is driven by perturbation more so than the slow drift of competition?
