Answer 10 оf the 17 Essаy questiоns belоw. In eаch Answer Box, you MUST specify which question you аre answering! 1) There are five ways to test for the influence of genetics on animal behaviors. Describe one of these ways, using an example from class or the book. 2) While working as a field assistant for Dr. B and Dr. E, you observe a female snake-eating bird solicit copulations from two different males. Dr B informs you that she mates with both males so that they will both provide parental care to the chicks in her nest, thereby increasing her fitness. Dr. E argues that the solicitation behavior is really just a result of increased day length (photoperiod) which results in an increase in the estrogen levels of the female. Who is right? What kind of explanation did each of them provide? 3) In terms of Fixed Action Patterns and Central Pattern Generators, explain the head bobbing of Uta lizards. What is the difference between FAPs and CPGs? How can you see this difference among the different morphs? 4) When a new lion takes over a lion pride, they sometimes kill the cubs already there. How is this trait at all evolutionarily advantageous? 5) If an altruistic act increases the genetic success of the altruist, then in what sense is this kind of altruism actually selfish? You should use Hamilton’s Rule in your explanation. 6) Explain (briefly) the TWO of the four hypotheses behind stotting in gazelles. What would you expect single animals or animals in a group to do for each hypothesis, assuming it is true? What is the most likely accurate prediction from the study? 7) As group size decreased within the driver-barrier bottlenose dolphins, it was possible to test for different cooperative interactions. Two were found. Explain both interactions (what was found and how it is evidence of cooperation). 8) Consider the following findings: In the years since 1950, pollution controls have reduced the amount of soot deposited on tree trunks, and the melanic form of the moth B. betularia has correspondingly become increasingly scarce in Europe and North America where the species also occurs. Put this statement in the context of a scientific investigation into whether the typical salt-and-pepper coloration of some members of this species constitutes an adaptation. Begin with a research question and proceed through hypothesis, prediction, test, and conclusion. 9) Explain A) the two mating strategies for male horseshoe crabs, B) the evidence for how they can coexist, and C) what you would expect for evidence if they could not coexist. 10) The Prisoner’s Dilemma assumes a one time interaction between players, but this is not always the case. How can the evolution of cooperation occur using this game? There are four strategies you need to discuss in this answer. What are the evolutionary advantages of each strategy? 11) A badger living in Oklahoma could hunt for either scorpions or ground squirrels (or both). Scorpions provide only 10 calories each, but they require only 2 minutes to find, on average, with an additional 3 minutes to remove the stinger; ground squirrels offer 1000 calories but take an average of 3 hours (180 minutes) to find and an additional 90 minutes to capture, kill, and consume. If the badger’s ultimate goal is to maximize its rate of caloric gain, should it forage for squirrels, scorpions, or both? Show your math (in fractions is fine). 12) How can group living evolve, according to the strategy of the Selfish Herd? Use an example from the book or class. 13) Explain the Optimality Theory (cost-benefit approach) of group living using the Northern bobwhite example. 14) How is an personality different than a behavior? What metrics are required to test for a specific personality? Include the three different graphs described by Dr. Keiser. You can describe what they look like instead of drawing them. 15) In the book, you read about Warner's experiments with bluehead wrasse, a coral reef fish. How did his research demonstrate a behavioral tradition of spawning site use? How could he rule out genetic or ecological factors to explain the observed behaviors? 16) Four conditions are required for evolution to occur via natural selection. A) Provide each condition, B) give an example for each one (use the same animal system throughout), and C) explain why evolution would not occur in absence of this condition. 17) Define eusociality in bees and describe how the haplodiploidy hypothesis relates to it.
