NPB 102, Animal Behavior Winter 2011 Study Questions for Chapter 7 1. What is a search image? What advantages (benefits) do search images confer, and what potential disadvantages (costs)? Describe experimental evidence illustrating these advantages and disadvantages. 2. What happens when Portia spiders are first primed with exposure to a preferred prey item and then presented with either the same or different prey in (a) a test situation where the prey is freely visible, and (b) a test situation where the prey is partially concealed? What does this result reveal about the role of search images in foraging behavior? 3. Explain whether you think it is more useful to quantify “detection” or “consumption” when evaluating whether or not a search image is present. 4. What is frequency-dependent selection, and how can it account for the co- existence of alternate foraging phenotypes? Provide at least one specific example. 5. What is the difference between a “strategy” and a “tactic?” Give an example where (a) a single tactic defines a strategy, and (b) a strategy involves multiple tactics. 6. Describe the behavior of ruddy turnstones foraging on sandy beaches with specific reference to the different tactics that individuals use. Is each of these tactics what you would call a “distinct strategy” or just a “separate tactic of a single conditional strategy?” Explain your reasoning.
