Individuаls оf а pаrticular species оf grоund beetle are either light tan or dark brown. Light-tan beetles are predominant in habitats with light-colored sandy soils, and dark-brown beetles are predominant in habitats with dark-colored loam soils. In an experiment designed to determine the survival rates of light-tan beetles and dark-brown beetles in different habitats, 500 light-tan beetles and 500 dark-brown beetles were released in each of four habitats. Each beetle had been marked with a small spot of red paint on the underside of its abdomen before it was released. One week after the beetles had been released, any marked beetles that could be found were recaptured. The results are presented in the table below. It is assumed that differences in the numbers of beetles recaptured are directly related to differences in survival rates. Columns 2 thru 5 have 2 sub-columns each. The top row contains the column labels: columns one is blank; Column two: Habitat 1: Sandy soil, no insectivorous birds present. Column three: Habitat 2: Sandy soil, insectivorous birds present. Column four: Habitat 3: Loam soil, no insectivorous birds present. Column five: Loam soil, insectivorous birds present. From top to bottom the data is as follows: Row two: Color of Beetle: Habitat 1, sub-column one, Light tan; sub-column two, Dark brown. Habitat 2, sub-column one, Light tan; sub-column two, Dark brown. Habitat 3, sub-column one, Light tan; sub-column two, Dark brown. Habitat 4, sub-column one, Light tan; sub-column two, Dark brown. Row three: Number Released: Habitat 1, sub-column one, five hundred; sub-column two, five hundred. Habitat 2, sub-column one, five hundred; sub-column two, five hundred. Habitat 3, sub-column one, five hundred; sub-column two, five hundred. Habitat 4, sub-column one, five hundred; sub-column two, five hundred. Row four: Number Recaptured: Habitat 1, sub-column one, one hundred thirty; sub-column two, one hundred fourteen. Habitat 2, sub-column one, one hundred twenty-three; sub-column two, twenty-two. Habitat 3, sub-column one, sixty-five; sub-column two, seventy-four. Habitat 4, sub-column one, thirteen; sub-column two, eighty-seven. If all insectivorous birds and remaining beetles were removed from habitat 2 and 500 additional dark-brown beetles and 500 additional light-tan beetles were then released into habitat 2, which of the following is the best estimate of the number of additional dark-brown beetles that would be expected to be recaptured in habitat 2 after one more week?
