Suppose this year your abundance estimate is 205 with a 95% confidence interval of 118 233.
Question:
Suppose this year your abundance estimate is 205 with a 95% confidence interval of 118 – 233. Next year you do another mark recapture study and get an estimated population size of 173 with a 95% confidence interval of 87 – 226. You are interested in the rate at which abundance is changing over time. You assume the population is following the exponential growth equation; see the equation below, where N0 is the initial population size, e is the mathematical constant (~2.718), r is the intrinsic rate of increase, t is time (number of time steps), and Nt is the subsequent population size: Nt = N0ert
Using the maximum likelihood estimates for abundance, what is the intrinsic rate of increase? (enter your answer with 2 decimal places, rounding up at 0.5; so 0.735 should be entered as 0.74)
