Question
Oct 15 F Franklin Forest Washington Forest Oct 15 Field Mice trapped and marked(Initial marked) 20 20Oct 17 Mice trapped 1717Oct 17 Mice trapped (number out of 17)that were already marked 5 15Which population is likely to have a bigger population given the information in the table above. AFranklin Forest BWashington Forest CCan not tell from the information given DThey are the same size
Solution
The Lincoln-Peterson index is a method used to estimate population size. The formula is N = (M*n)/m, where:
- N is the estimated population size
- M is the number of individuals initially captured, marked, and released
- n is the total number of individuals captured in the second sample
- m is the number of marked individuals recaptured
For Franklin Forest: N = (20*17)/5 = 68
For Washington Forest: N = (20*17)/15 = 22.67
Therefore, Franklin Forest (A) is likely to have a bigger population given the information in the table above.

Two different species of deer are housed in two separate areas of a wildlife park. The initial population of species A was 300, and the population is increasing by 15% every year. The initial population of species B was 400, and the population is increasing by 7% every year.Use the given information to determine when the two species will have the same population.After years, the populations of the two species will be approximately equal, with deer of each species.
A population of mice has 2,000 individuals. They have a death rate of 160 per year and a birth rate of 160 per year. Assuming 19 mice migrate into the population and 19 migrate out of the population per year, how many individuals would there be after the first year? (To answer, write numerals in the box below.)
