The sizes of animal populations are often estimated by using a capture-tag-recapture method. In this method k animals are captured, tagged, and then released into the population. Some time later n animals are captured, and Y, the number of tagged animals anong the n, is noted. The probabilities associated with Y are a function of N, the number of animals in the population, so the observed value of Y contains information on this unknown N. Suppose that k 4 animals...

Twelve koalas born and raised in captivity were tagged and released into the wild in a certain region of Australia. Subsequently 4 koalas were sampled (captured) without replacement and 2 were found to be tagged. Estimate the size of the koala population for this region.

Based on mark/recapture studies between 2001 and 2006, the Southern Beaufort Sea 2006 population of polar bears is approximately 1526 bears. Suppose that since 2006 the population is being renewed at a rate of r(t) = 0.180 + 0.012t thousand bears per year and that the survival rate is 89%, where t = 0 corresponds to 2006.† (a) How many of the 2006 population of 1526 polar bears will still be alive 27 years from then?

If managers took 10 random individuals from the population
today, calculate and discuss the expected number
of alleles in that founder population for each locus.
Plains Wanderer samples were collected from two points in time. A pre-clearing historic sample was collected from feathers stored in a museum collection. This historic sample included 40 samples from a collection of specimens shot in 1955 at a single population near Warracknabcal. Victoria. A post-clearing contemporary sample was collected in 2015 from the same...

Environmental scientists believe that there is a decline in the population of frogs around the world. They speculate that declining frog populations are a symptom of deteriorating environmental conditions. How would these scientists gather accurate data about existing frog populations? How would they use these data to speculate on previous or future population levels? Imagine that a wetland you are studying has a population of 5000 frogs, including bullfrogs, spring peepers, and mink frogs. The populations...

Problem 5 5.a Consider the following identity. For all positive integers n and k with n 2k, (n choose k) + (n choose k-1) = (n+1 choose k). This can be demonstrated either algebraically or via a story proof. To prove the identity algebraically, we can write (n choose k) + (n choose k-1) = n!/[k!(n-k)!] + n!/[(k-1)!(n-k+1)!] = [(n-k+1)n! + (k)n!]/[k!(n-k+1)!] [n!(n+1)/k!(n-k+1)!] = (n+1 choose k). Which of the following is a story proof of the identity? Consider a...
