Behavioral Ecology
  • Ethology is the study of the behavior of animals
    in their natural environment.

3
Behavioral Ecology
  • Ethologists ask proximate questions, such as
    What triggers this behavior? and ultimate
    questions, like Why did natural selection favor
    this behavior?

Behavioral Ecology
  • Fixed action patterns (FAPs) are unlearned,
    unchangeable behaviors triggered by a sign
    stimulus

  • Imprinting is learning during a sensitive period.

Behavioral Ecology
  • Kinesis is a change in activity level or turning
    rate in response to a stimulus.

  • Taxis is movement towards or away from a stimulus.

  • Altruism is explained by the concept of inclusive
