"Stable Isotopes in Forensic Analysis" Read an article about the use of stable isotopes in forensic analysis for law-enforcement purposes.You may read one of the suggested articles, below, or one of your own choosing. Then, in a primary post of at least 125 words, in your own words, explain what a stable isotope is and how stable isotope analysis can be an aid to law enforcement forensics. Make a substantive reply to at least one fellow student.Ackerman, S. J. (2013, January/February). A different kind of CSI: crime and stable isotopes. American Scientist.

BIO Unit VII Unit VII Web Assignment Unit VII Web Assignment: Deforestation Deforestation is the removal of trees in a forest by natural and human actions and rates of deforestation vary across the world. In this assignment, we will examine patterns of global deforestation and their causes using the New York Times Changing Forest website. Instructions A. Open the New York Times Changing Forest website for an interactive map of world forests: Click the link below to access an interactive map of world forests: Bloch, M., & Corum, J. (n.d.). Changing forests. Retrieved from http://www.nytimes.com/interactive/2011/10/01/scie... You will first see a world map. Give it a general look to gain your coordinates and to see the locations where intact, relatively undisturbed forests and fragmented forests occur. B. Next, zoom into the specific areas of the Earth to gain a more detailed perspective on deforestation by region. First, click on North America. There will again be a view of intact and fragmented forests also with two buttons on the bottom right of the screen: Recent losses and Ancient forests. Click these buttons to see recent deforestation in North America and the former extent of ancient forests. Do this for each of the other regions on the map (Europe, Asia, South America, Africa, and Australia). Then answer the 10 multiple-choice questions (8 points each), and one short answer question (20 points) in Blackboard. QUESTION 1 What two temperate areas of the world are seeing forest regrowth? Australia and North America Europe and Asia Australia and Asia North America and Europe 8 points QUESTION 2 What region of South America is experiencing the greatest amount of deforestation? Argentina Amazon Basin Colombia Peru 8 points QUESTION 3 Since 2000 forest fires and extended drought have significantly impacted forests in which country? Australia Canada Congo United States 8 points QUESTION 4 Which region is losing an estimated 10 million acres of forest yearly? South America North America Asia Australia 8 points QUESTION 5 Where in Europe is forest loss the greatest? Sweden Italy Spain France 8 points QUESTION 6 How many acres of forest are left in the world? 100 million 1 billion 9.9 billion 17 billion 8 points QUESTION 7 Why does the Congo region in Africa still have significant forest cover? Strict conservation laws. Lack of infrastructure and political instability. Protection by the United Nations. Fierce lowland gorillas. 8 points QUESTION 8 Which country in the world has greatest percentage of forest? Canada Russia United States Brazil 8 points QUESTION 9 What is the major natural factor that is causing deforestation in western North America? Fire Logging Mountain pine beetle infestation Excess rainfall 8 points QUESTION 10 Despite having only 5% of the world's forest cover, which nation is effectively fighting desert encroachment by planting huge numbers of trees? Kazakhstan Mongolia India China 8 points QUESTION 11 Using data from the New York Times Changing Forest website, explain how forests are impacted by climate change and how forests themselves may offset aspects of climate change. Be specific in your examples. Your response should be 100 words in length. BIO 1302 Unit VII Quiz QUESTION 1 This technological tool used by ecologists can be employed to determine deforestation rates across the world. Global positioning system Geographic information system Remote sensing Mapquest 10 points QUESTION 2 In which element in a fragmented landscape would you expect to find the largest number of species? A long, thin patch In a corridor In a large patch connected to a corridor In a small patch connected to a corridor 10 points QUESTION 3 Which of the following ecological services provided by conservation areas would be associated with flood control? Provisioning services Regulation services Cultural services Habitat services 10 points QUESTION 4 Forest thinning is done in a conservation area to provide open habitat for a particular plant species. The timber is sold to the highest bidder. What type of ecological service would this action be? Provisioning services Regulation services Cultural services Habitat services 10 points QUESTION 5 Which of the following practices would not be used to restore longleaf pine savanna in the American South?
