tailieunhanh - Lecture AP Biology - Chapter 51: Animal behavior

In this chapter, students will be able to understand: How behaviors are the result of natural selection, how innate and learned behaviors increase survival and reproductive fitness, how organisms use communication to increase fitness, the role of altruism and inclusive fitness in kin selection. | Ch. 52 Review Names the biomes labeled a-f in the climograph. What is something that you can do that you have been able to do since birth? What is one behavior that you learned by watching someone else? List some ways that animals communicate. Ch. 51 Warm-Up Define: Circadian rhythms Pheromones Learned behaviors Imprinting Associative learning Classical conditioning Operant conditioning What is the difference between proximate and ultimate causes of behavior? Explain the difference between kinesis and taxis. What are the 4 common modes of animal communication? Ch. 51 Warm-Up Define: Optimal foraging model Sexual Selection Promiscuous Monogamous Polygamous Altruism Inclusive fitness Kin selection Ch. 51 Warm-Up What do you think is the advantage for a species to be: Monogamous? Polygamous? Describe an example of when you have participated in reciprocal altruism. Chapter 51 Animal Behavior You Must Know: How behaviors are the result of natural selection How innate and learned behaviors increase survival and reproductive fitness How organisms use communication to increase fitness The role of altruism and inclusive fitness in kin selection Introduction Ethology: study of animal behavior Behavior: what an animal does and how it does it Both genetic & environmental factors Essential for survival and reproduction Subject to natural selection over time Understanding behavior Proximate cause: “how” a behavior occurs or is modified Ultimate cause: “why” a behavior in context of natural selection A courting pair of East Asian red-crowned cranes. BEHAVIOR: A male stickleback fish attacks other male sticklebacks that invade its nesting territory. PROXIMATE CAUSE: The red belly of the intruding male acts as a sign stimulus that releases aggression in a male stickleback. ULTIMATE CAUSE: By chasing away other male sticklebacks, a male decreases the chance that eggs laid in his nesting territory will be fertilized by another male. Innate behaviors: developmentally fixed and are not | Ch. 52 Review Names the biomes labeled a-f in the climograph. What is something that you can do that you have been able to do since birth?
