Integrаtive 1 (20 pts. tоtаl) Suppоse thаt females оf songbird Species A exhibit variation in the number of eggs they lay during a typical breeding season. Average clutch size is 5, but females can lay anywhere between 3 and 7 eggs per clutch. a. Describe what will occur over time if disruptive selection operates on clutch size. (5 pts.) b. Name and describe one factor that will lead to continued variation in clutch size in the population, despite the occurrence of disruptive selection. (5 pts.) Suppose that Species A is highly susceptible to a brood parasite, and you witness a female brood parasite about to lay in a nest of Species A. The parasitic female removes two eggs from the nest, and lays two of her own that are almost identical in color and size to the original eggs. However, when the nest owner returns, she inspects her nest and tosses the two parasitic eggs. c. How would a classic ethologist (e.g., Niko Tinbergen) interpret this situation? Describe how he would classify the overall behavioral behavior pattern of the Species A female, and how he would describe the components of her egg-tossing behavior. (5 pts.) d. Suggest one explanation for the Species A female’s egg-tossing behavior that takes an immediate causation or mechanistic approach to the behavior (think of Tinbergen’s four questions). (5 pts.) PLEASE LABEL YOUR ANSWERS WITH (a), (b), (c) and (d).
