OLM 7.1. The equilibrium resource density with fluctuating growth rates

 

Ch7Excl has shown that competition for a single resource in a constant environment leads to the exclusion of all other populations by the one which attains zero growth rate at the lowest resource density. In such a situation each of the competing variants can be characterized by the resource density at which its growth rate (r) is zero. Following Tilman’s terminology, this is called the R* value of the species with respect to that specific resource. In this OLM we compare the equilibrium resource density in a constant environment to the average resource density  at which the average growth rate is zero in case of fluctuating resource supply rates.
