QUESTION 2: Population size One weekend in early July, a total of 154 Marbled White butterflies were captured and marked before being released. The following weekend, the butterfly traps captured another 87 butterflies, but only one was marked. a) Based on these data, estimate the butterfly population size (show your workings in full). b) Estimate the population size if, instead of one, the number of marked butterflies was: i) 2 ii) 10 iii) 25 You do not need to show your workings for this part. c) Would all of these results give equally accurate estimates of population size? Explain your reasoning. d) The following year, the researcher returned to the same spot, on the same July weekend in order to evaluate whether the butterfly population size was similar year-on-year. This time, however, the recapture phase occurred only three days after marking. Do you think this would affect the accuracy? Explain your answer fully.
