  1. What is Behavior?
    everything an animal does and how it does it
  2. Why are the biomes where they are and how do we get them?
    • Different wind and percipitation patterns
    • climate determines distribution and structure of terrestrial biomes
  3. What are proximate causes? Example
    • reffered to as the "how" questions
    • focus on the environmental stimuli, if any, that trigger a behavior
    • also focuses on the genetic, physiological, and anatomical mechanisms underlaying a behavioral act
    • how a behavior happens and what it looks like
    • Ex: How day length influences breeding by the red-crowned cranes
  4. What are Ultimate causes? Example?
    • reffered to as the "why" questions
    • they address the evolutionary significance of a behavior
    • how does behavior contribute to survival and reproduction
    • adaptive value, why it is happening
    • Ex: Why natural selection favors this behavior over another one
  5. What is Ethology?
    the study of how animals behave
  6. Who are the pioneers in the study of the animal behaviors?
    • Karl Von Frish
    • Niko Tinbergen
    • Konrad Lorenz
  7. Who was Karl von Frish? What did he do?
    • biologist
    • studied honeybees
    • he noticed workers had a specific way of telling the colony where the food was
    • ---> the waggle dance
  8. Who is Niko Tinbergen? What did he do?
    • scientist who studied fixed action patterns
    • Fixed Action Patterns: innate behaviors that continue once started no matter what
    • studied sticklebacks-the color red was a sign stimulus that triggered aggression
  9. Who is Konrad Lorenz? What did he do?
    • scientist who studied geese
    • saw imprinting in the geese
    • Imprinting: learning to form social attatchments at the specific critical period (innate and learned characteristics)
  10. What are Innate behaviors?
    • Inherited behaviors
    • Instinctive
    • developmentally fixed, strong genetic component
    • ex: migration is an innate behavior
  11. What are types of innate behaviors?
    • Taxis & Kinesis
    • Bird Migration
    • Fixed Action Patterns
    • Imprinting (innate and learned)
  12. What is Taxis? What is an example?
    • direct movement towards or away from a stimulus
    • ex: phototaxis in plants- movement towards light
  13. What is Kinesis? Give an example
    • a non direct response to a stimulus
    • ex: moving around doing a bunch of different things and stopping to notice a candybar
  14. What is Bird Migration? Talk about the experiment
    • considered a complex innate behavior
    • migratory restlessnes seen in birds bred and raised in captivity
    • navigate by sun, stars, earth magnetic fields
    • experiment cross bread birds who migrate with ones who didnt and 40% of offspring tried to migrate- inherited
  15. What are Fixed Action Patterns?
    • sequence of behaviors essentially unchangeable and usually conducted until completion once started
    • triggered by a sign stimulus
  16. What is a sign stimulus?
    the releaser that triggers a fixed action pattern
  17. What is Imprinting? How does it affect evolution?
    • learning to form social attatchments at specific critical period
    • organisms during that period who follow adult are more likely to survive, helping evolution
    • both learning and innate components
  18. What is the Critical Period?
    sensitive phase for optimal (viusual) imprinting
  19. When must some behavior be learned? Example?
    • during a receptive period
    • for some birds, learning their songs the bird will have passive listening during the sensitive period, when they are juvenile, they have a subsong, and it takes until adulthood for the final crystalized song
    • however some songs are inherited
  20. What is Learned Behavior?
    modification of behavior based on experience
  21. What are the types of learned behavior?
    • Habituation
    • Spatial Learning
    • Associative Learning
    • Social Behavior
    • Problem Solving
  22. What is Habituation?
    • Loss of response to a stimulus
    • the "cry wolf" effect
  23. What is Spatial Learning?
    the modification of behavior based on experience with the spatial structure of the environment, including the locations of nest sites, hazards, food, and prospective mates
  24. What is the experiment that Tinbergen did with digger wasps for spatial learning?
    Tinbergen moved the circle of pinecones surrounding a wasp nest and found that the wasps had used it at a landmark, because they still returned to the center of the pinecones when they had been moved from the hive
  25. What is associative learning?
    • learning to associate one feature of the environment with another
    • 2 types
  26. What are the 2 types of associative learning?
    • Operant Conditioning
    • Classical Conditioning
  27. What is Operant Conditioning?
    • trial and error learning
    • associating a behavior with a reward or punishment
    • ---->ex: the skinner box- if the rat pushed the button at a green light- reward food... if pushed at a red light punishment- no food or electric shock
    • the rat over time learns when is good to push the button
    • ex: learning what to eat is operant conditioning
  28. What is Classical Conditioning?
    • Also called Pavlovian Conditioning
    • Associate a "neutral stimulus" with a "significant stimulus"
    • ---->pavlov's dogs associated bell ringing (neutral stimulus) with food (significant stimulus)
    • connect a reflex behavior (salivating) to associated stimulus
  29. What is Social Behavior?
    Interactions between individuals
  30. What are the types of social behavior?
    • Agonistic
    • Dominance
    • Cooperation
    • Altruism
    • Communication
  31. What is Agonistic behavior?
    Behavior in animals, often a competition, which by strength or something determines the winner that will gain access to a resource such as food or a mate
  32. What is Dominance?
    Social Ranking among animals
  33. What is cooperation?
    Animals working together to accomplish something
  34. What is Altruism?
    • selflessness- rarer in animals
    • an animal risks its chances of dying to save another
    • is it worth it? find out by Hamiltons rule
  35. What is communication
    • the transmission, reception and responce to signals
    • autitory: hearing- loud calls of birds may attract mates
    • chemical: pheromones- moths give of pheromones to attract mates
  36. What is cognition?
    the ability of an animals nervous system to percieve, store, process and use info gathered by sensory receptors
  37. Explain Problem Solving?
    • the nervous system processes information to help the animal think to solve the problem
    • ex: chimps learn to use tools to crack open nuts
  38. What is foraging?
    behavior associated with recognizing, searching for, capturing, and consuming food
