i. The capture and release method (Lincoln index) is used to estimate the size of a population. List TWO assumptions that are made, when utilizing this method. ii. To estimate the population size of rats in Bridgetown, a mark and recapture exercise was conducted. 150 of the animals were randomly captured and tagged in the first sampling effort. After four weeks a second sampling effort was carried out during which 110 rats were caught, 50 of these possessed tags given in the first sampling. Use the Lincoln index equation to estimate the population size of rats in Bridgetown iii. Suggest one scenario that could occur within the 1-month period between sample taking, which could lead to a LOWER population estimate.
