Beverton–Holt model
The Beverton–Holt model is a classic discrete-time population model which gives the expected number n t+1 (or density) of individuals in generation t + 1 as a function of the number of individuals in the previous generation, n t + 1 = R 0 n t 1 + n t / M . {\displaystyle n_{t+1}={\frac {R_{0}n_{t}}{1+n_{t}/M}}.} Here R0 is interpreted as the proliferation rate per generation and K = (R0 − 1) M is the carrying capacity of the environment.
