<p>Name ______</p><p>AP Environmental Science, Mr. Shannon Discovery High School</p><p>BIODIVERSITY WEBQUEST </p><p>Follow the links below and answer the relevant questions. You may submit this WebQuest when it is completed (and ONLY when it is completed!) to Mr. Shannon at [email protected].</p><p>“Just How Many Species Are There, Anyway?” http://www.sciencedaily.com/releases/2010/06/100602142045.htm</p><p>1. What is one reason why having an accurate count of species is important?</p><p>2. How many methods of assessing biodiversity did Rosenzweig and his colleagues test?</p><p>3. What is Rosenzweig’s best estimate for the total number of species on planet Earth? Is this an accurate guess? Why or why not?</p><p>4. Which method worked best – choosing ecoregions at random or spacing them evenly throughout the continent? Defend your answer.</p><p>5. What are the long-term implications of Rosenweig’s method (Hint – could it be useful in other contexts? How?) “Who Are We Sharing The Planet With? Millions Less Species Than Previously Thought, New Calculations Suggest”</p><p>6. Who was the study’s lead author, and where does he work?</p><p>7. Which species are included in the arthropod group?</p><p>8. How are applied probability modeling techniques typically used?</p><p>9. Approximately what percent of all arthropods are estimated to be awaiting discovery by humans?</p><p>10. How did the scientists in the article account for uncertainty when estimating the total arthropod diversity of the rain forest?</p><p>“How Many Animal Species Inhabit Our Planet?” </p><p>11. What challenges can species’ habitats present to estimating biodiversity?</p><p>12. What percent of total species are classified as invertebrates? 13. What are some additional ways (beyond “total number of species in a given area”) that ‘biodiversity’ is used?</p>
