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?
To measure the population of lake trout in a 250-hectare lake, 100 individuals were netted and marked with a fin clip, and then returned to the lake. The next week, the lake is netted again, and out of the 300 lake trout that are caught, 15 have fin clips. Using the capture-recapture estimate, the lake trout population size could be closest to? Also, what formula do I use to solve this problem? Thank You!
In an effort to measure the size of a bluegill population in a pond, you set 10 traps for bluegills. You catch and mark 40 with a tag on the tail fin and then release them. A week later you return to the pond and set 10 traps and you catch 40 more, of which 8 have a tag on the tail fin. What is the best estimate of the bluegill population in the pond?
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

You visit the Apalachicola National Forest and capture, mark and release 30 fence lizards. A week later you return and capture 25 lizards, 5 of which are recaptures from the previous sample. What is your best estimate of the lizard population size?
The neighborhood of a lake has a population of snails, which come out onto the sidewalk when the sprinklers come on, and the rest of the time they hide in the vegetation. If you catch 20, and mark them and, then, a week later, after they have had a chance to disperse into the population, you catch 15, and 6 have marks on them, what is the estimated size of the population?
A population of wolves in a national park is known to be 150 individuals. 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.
You are conducting an ecological study of two populations of invasive Italian Wall lizards in New York City, one in the Bronx and one in Staten Island. You decide to study the two populations using mark recapture in a 1 hectare plot in each park. In the Bronx, the park you sample is 100 hectares (1 km2), you mark 18 lizards initially. During your second sampling in the Bronx, you capture 20 lizards - of which 8 are recaptures (i.e., you marked them in the first sampling period). In Staten Island you sample a smaller park that is only 30 hectares in size, you mark 32 lizards initially. In Staten Island, you capture 43 lizards in your second sample - of which 24 are recaptures. 1. Which park has the larger estimated population size according to the mark-recapture survey? Choice 1 of 2:The Bronx Choice 2 of 2:Staten Island 2. You start to think that your estimates of population size might be a little too high. What is one reason why your estimates of population size might be…
After examining two specific organisms on Movebank.org, consider the movement trends of the two organisms and discuss the importance of this type of data. Consider the resources related to tracking methods and discuss the benefits of this kind of research in understanding and protecting wildlife populations. Is it important to know the details of wildlife populations? Is there a point do where scientists go too far? Share your opinion on the importance of knowing the size of a given population and defend your position.
