WebWhen we plot the annual per capita growth rate, rt = log(Nt + 1 / Nt), as a function of N, we see a pattern emerge. At low N, r > 0, whereas at high N, r < 0. The annual growth rate depends on the size or density of the population. This is the sort of thing we mean when we use the term density-dependent growth.
