Introduction: The mark-recapture technique involves the capturing of the individuals of a population and marking them with identification tags. Then, these individuals are released and allowed to freely mix with the population. After some time, a recapture and sampling of the marked and unmarked individuals can help us to estimate the population sizes.

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?

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 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?arrow_forwardA large conservation agency in Austria is interested in the status of the endangered newt species, Triturus austriacus, and wants you to estimate population sizes.

- 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_forward(Number marked × total number recaptured)# recaptured with mark/Number marked × total number recaptured# recaptured with mark The formula above is the equation for estimated population size using the Mark and Recapture method of population estimation.

Overfishing of S. galilaeus in 2008 led to a drastic decline in their population size. Although the population has since increased, the genetic variation in S. galilaeus is still low. At which point on the graph was the population most vulnerable to the bottleneck effect due to a natural disaster and why? A. Y, because the population is small and there is low genetic diversity B. Z, because the population is large but the genetic diversity has remained low C. X, because the population is too large and has exceeded its carrying capacity D. W, because the population is just starting out and natural selection is still taking placearrow_forward
