Chapter 15, Problem 1AAATB
A researcher captures 50 penguins, marks them with a spot of paint on their bills, and releases them. One month later, the researcher returns, captures another 50 penguins, and notes that only 1 has a previous mark. What is the likely size of the total penguin population in the researcher’s study area?

You are contracted by the City of Ottawa to estimate the size of the population of
small mouth bass in Dow's Lake. Using nets, you capture, mark, and release 48 bass.
You return to Dow's Lake two weeks later and use the same techniques to sample
more bass. This time, you capture 39 bass, 18 of which you had previously captured
(marked ones). What is the estimated size of the population of small mouth bass in
Dow's Lake? Round your answer to the closest whole value. You can round up or
down if your answer is exactly between two values (i.e. 0.5).
You want to estimate the population size of pink salmon in the upper pitt river and use a mark-recapture technique to do so. You mark 1313 individuals as they pass under the port mann bridge. two weeks later you recapture 2245 individuals in pitt lake of which 204 have marks on them. What is your estimate of the population size?
The mark-recapture method is used to estimate the population size of mountain yellow-legged frogs in the San Gabriel Mountains of southern California. 100 frogs are captured and marked. A week later, 50 frogs are captured, and 10 of them are marked. The total population size is

As wildlife ecologist, you are tasked with assessing the accuracy of the mark and recapture technique. At the start, you mark 30 wolves, and your recapture yields 20 wolves, 5 of whom are marked. State whether the mark and recapture data results in an over or underestimation of the actual population size, and show work to support your claim.arrow_forward
