Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.

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.
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).
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.

Wolf biologists started estimating the number of wolves in 2000 at 21 wolves in GTNP population. In 2010 they repeated their population surveys and counted 105 animals. What is the doubling time for this population? The Tripling time? What is the current (2022) estimated population?

Is the wolf population controlled by density or density-independent factors? Explain using one piece of information from the reading to support your choice. You should use those supports to back up your choice, that is, how did this piece of support lead you to your answer.
There was another research effort underway to estimate the squirrel population on the PLU campus. The first trapping effort resulted in 15 individuals being captured, marked and released. The second capture effort resulted in 15 new squirrels being captured and 5 squirrels were recaptured. What is the estimated squirrel population? What are the primary assumptions of the population estimation procedure used in this question?
