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 37 bass, 16 of which you had previously captured (marked ones). What is the estimated size of the population of small mouth bass in Dow's Lake?

- 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).arrow_forwardSuppose that none of the 44 dolphins encounteredin the second sampling had been photographed before.

The results suggest that each population is quite different from the other, such that each population should be managed as a distinct and unique population. O b. Populations 1 and 2 are completely isolated from each other and should be managed separately even though they are both more similar to population 3. O c. There is evidence of gene flow between populations 1 and 2, and they should be managed as a single population while population 3 is unique. O d. There is no evidence of differentiation between all…arrow_forwardYou and your team continue to study the population of long-tongued pucas.
