EEB100 Ecology Study Questions Page 1 of 6 Study Questions Questions with asterisks (*) will have answers in the accompanying key. 1. At what latitudes do we generally find forests and deserts? Describe the global circulation pattern that causes this. 2. List and describe the three causes for deserts. 3. * A fantastically wealthy and not-very-environmentally-conscious person decides to build their own island near the equator. They also decide that they would enjoy having a desert environment. They hire you as a consultant on designing the island, which can be any size and have any geomorphology they like. a. How would you explain to the crazy rich person that desert islands (not to be confused with deserted islands) are unlikely at low latitudes? b. Based on what we covered in class, what are two methods you could use to terraform the island and create a desert, or at least much dryer conditions, on part of it? 4. What are two reasons that coastal areas are typically cooler than continental interiors during the summer? Of those two, which is the reason that continental interiors are typically colder during the winter? 5. Describe the process of upwelling, including the Coriolis effect. Why is this process important biologically? 6. *Imagine you are on a planet that is exactly like the earth, but rotates in the opposite direction. On which coastlines, west or east would you expect top find more upwelling? Why? 7. In the logistic model, what prevents populations from growing exponentially? 8. On the graphs below, draw in curves for logistic and exponential growth 9. Forrero et al. (2002) investigated density dependence effects on the biology of Magellanic penguins. What two aspects of penguin biology seemed to be affected by density dependent processes? How were they measured? 10. Name and define six characters that differ between K and r selected species. Be explicit about which characters are associated with each. 11. What are the three types of survivorship curves? Which curves do r and K selection correspond to? N at time t N at time t + 1 Time N
