Write yоu аnswer tо pаrt (а) in the bоx below (be sure to also indicate which essay you are answering: 1, 2, 3, or 4- ONLY CHOOSE ONE). You MUST STICK to the same question set (1, 2, 3, or 4) for each sub question you are answering. (18 Points) Option 1 General Ecology: b. In the predatory response experiment discussed in class, researchers flew a kite over a group of turkey chicks. When the kite was flown in one direction, it resembled a hawk. When it was flown in the opposite direction, it resembled a goose. The turkey chicks responded to the hawk kite by crouching and hiding, but ignored the goose kite. This experiment suggested that the birds only respond to predators that are a known threat to the species. State whether this study is correlative or causative and why? Is it between groups or repeated measures design? Is this study a theoretical, field or laboratory study? State whether it is descriptive functional and evolutionary and defend your answer. Option 2: Evolutionary Ecology b. The graph below shows the distribution of phenotypes for a population of mice. How would the distribution of phenotypes in the population change over time if: i. The population is undergoing stabilizing selection. ii. The population is undergoing disruptive selection. iii. The population is undergoing directional selection for darker colored mice. Provide and describe a real but non-mouse example for each of these different types of selection leading to evolutionary change in nature. Option 3: Understanding Distributions b. You are using a transplant experiment to understand the limitations of a particular species in terms of geographic range. You have two areas: Area A (the species current range) and Area B (outside of the species current range). You transplant members of your species to area B. How would you interpret each of the following outcomes in terms of why the species does not inhabit Area B: i. The organism survives and reproduces in Area B just as well as it did in Area A. ii. The organism survives in Area B just as well as it did in Area A, but does not reproduce. iii. The organism does not survive in Are? B. Give an example of an actual transplant experiment. What was done? What were the key results? Option 4: Biological Control b. If you were going to introduce a species to an area what would you want to know before the introduction? What type of studies would you do to find out this information before the introduction – describe in detail and be thorough? Think of studies we’ve discussed so far in class.
