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 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?
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 a mark–recapture study to estimate the size of a rodent population, researchers catch and mark 180 individuals. Two days later, they again trapped and 40% of the 100 individuals captured carried a mark from 2 days earlier.

- https://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html This section starts explaining how scientists use the population survey data that are collected to model how the lionfish population changes over time. These models enable scientists to make predictions about population changes, which is an important element of developing plans for managing the lionfish population You'll be using the discrete-time logistic model that is described on this page in future parts of the case study, so make sure to carefully read through the explanation of this mathematical model. Even if you don't have a strong math background, this case study walks through the equation step by step. 6)Which of the following are constant terms in the discrete-time logistic model? choose all that apply a)Nt b)ΔN c)t d)K e)Δt f)rmax,d g)None of thesearrow_forwardIn a population of solitary and independent birds, birds occasionally will build nests close to each other. Females will provision their young with food, but may not have enough for themselves. The bird may try to obtain additional food from their neighbors by visiting their nest. Occasionally the neighbor may share some of its food with the visiting bird. What is necessary for this altruistic behavior to persist in this population and why?arrow_forwardA 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.arrow_forward
