We estimate the size of a population of small mice in a particular field by the mark-response method. Our estimate is 350. Later, we learn from experiments on the behavior of these mice that they can locate a baited trap faster if they have already been rewarded with food by visiting that trap once before. Does this mean that our original estimate of 350 individuals was too low or too high? Explain your answer in terms of the principles that underline the mark recapture method.
