ECOL100 Module 4 Case

Assignment Overview
In this module, you have learned about how carrying capacity imposes restrictions on population growth, and how human economic growth and land use can threaten biodiversity. In this Case Assignment you will look at these topics from three perspectives:

Case studies of government regulation of land and trade restrictions to address threatened species in the Economist article: Political Responses: Where eagles dare
Examples of large mammals and the size of the habitat necessary to support them
The cost of conservation in a Botanical Garden case study

Case Assignment

Part I

To prepare for this Case Assignment, answer the following in paragraph format (one paragraph should be plenty):

Define invasive species using the U.S. Department of Agriculture (USDA) website: National Invasive Species Information Center. USDA. invasivespeciesinfo.gov
Provide three examples of invasive species in your region.
Define endemic species, and provide an example of an endemic species from anywhere in the world. If you can find an example of an endemic species in your region, please include it as well.
Now read the following article:

Where eagles dare: The more prosperous countries now favour protecting wildlife, not killing it. (2013). https://search-proquest-com.ezproxy.trident.edu/docview/1433080524?OpenUrlRefId=info:xri/sid:summon&accountid=28844

After you have read the article, answer the following questions in paragraph format by using an introduction sentence, related topic sentences, and a conclusion statement that draws connections between the ideas presented.

Name some ways that governments are trying to redress threats against endemic species. Briefly, describe the examples presented in this article.
What is described as the biggest challenge for governments?
How are governments addressing this challenge?

Part II

With habitat loss, less land and resources mean lower carrying capacity. For the second part of this assignment, you will apply the readings from your Module 4 Homepage to two cases in which conservation of habitat applies to carrying capacity and economics. Choose one of these large predators to investigate: One of the large cats (i.e., lions, cougars, panthers, etc.) or polar bears.

What size of land/water is required to support this animal?
What pressures threaten this organisms habitat?
What role do international trade and political regulation play in protecting this organism? Are these in place and enforced?

Part III

Finally, examine the costs and benefits of conservation using the following article as a case study.

Drechsler, M., Eppink, F. V., & Wtzold, F. (2011). Does proactive biodiversity conservation save costs? Biodiversity and Conservation, 20(5), 1045-1055. doi:10.1007/s10531-011-0013-4. Available in the Trident Online Library.

What are the costs associated with delaying the conservation of biodiversity? (Generally speaking, not exact numbers.)
What are the benefits of preserving biodiversity and how are they measured? (Hint: conduct independent research to determine methods of measurement.)
Assignment Expectations
Organize this essay assignment using subtitles that summarize the topic from each question above. For example, to answer Question 1, use a descriptive subtitle like the following: Part I: Invasive Species.

Answer each question under the subtitle using complete sentences that relate back to the question. Be sure to use APA formatting throughout your essay with 1-inch margins, 12-point type, and double spacing throughout. Include a title page, introduction, answers to the questions with subtitles, and concluding paragraph.
