Check convergence to a dynamical equilibrium
In initial simulations, I noticed that the number of guilds in system achieved first to a stationary state; then, the species richness achieved eventually to a dynamical equilibrium through speciation-extinction balance. Furthermore, setting the same seeds in random number generator, the simulation outcomes from alternative diversities; monodominance (i.e. all individuals of each guild were single species) and infinite (i.e. all individuals of each guild were different species) converged when the species of each guild in regional species pool were originated from the different common ancestor individuals in the simulation outcome from monodominance guilds (hereafter convergence time). The simulations reported here were started from monodominance guilds.
