Estimates of λ or r are often used to determine how rapidly a population is growing (or declining) at various points in time. For a population that is growing exponentially, we can estimate the exponential growth rate (r) using the following equation: where N(0) is the population size at the beginning of a time period, t is the length of the time period, and N(t) is the population size at the end of the period. In this exercise, we’ll use...
