Goals• Define behavioral ecology.• Explain & give examples of the following kinds of animal behavior:• Instinct• Fixed action patterns (FAP)• Imprinting• Associative learning & classical conditioning• Trial & error learning (operant conditioning)• Habituation• Observational learning• Insight• Explain the reason for migration and list the 3 ways organisms know where to go.• Social behavior:• Discuss how each of the following competitive social behaviors helps organisms survive & give
examples:• Agonsitic• Dominance hierarchies• Territoriality• Explain the purpose of courtship behaviors & why females are so picky about the mates they
chose.• Describe altruistic behavior & give an example.• Communication:• List 3 modes of communication among organisms & 2 reasons why organisms communicate.
Ch 35 Behavioral Biology
Ch 35 Behavioral Biology• Behavior – what an animal does & how it does it• Behavioral ecology – research approach based on
expectation that animals increase their Darwinian fitness by optimal behavior.
• Darwinian fitness – the relative contribution an individual makes to the gene pool of the next generation.
Innate Behavior• Instinct; determined by genes
– Developmentally fixed – same behavior despite env differences inside & outside their bodies
– Fixed Action Pattern (FAP) – a sequence of behaviors, unchangable & carried to completion
• Triggered by sign stimulus• Ex: moths fold wings in response to ultrasonic signals of bats
• Ex: bird with egg rolling out of nest• How do these work to enhance fitness?
Learning• Experience based modification of behavior
– Most innate behaviors improve w/ experience (flying / developmental…)
– Habituation – simple type of learning – loss of responsiveness to stimuli that convey little or no info
• Ex: hydra stop contracting tentacles when touched repeatedly w/ out any danger
Mating Behavior• Relates directly to animals fitness• Courtship – sequence of actions that confirms:
– Same species but opposite sex– In appropriate physiological condition– Not a threat– Moonwalking bird belowhttp://www.youtube.com/watch?v=072A5xbhO3I&feature=relatedMating dance…http://www.youtube.com/watch?v=7dx2CUMtZ-0&feature=related
• Parental Investment – time & resources an individual must expend to produce offspring– Choose wisely to make it worth it / genetic quality– Females mammals picky b/c they have high investment / males
usually have pronounced 2ndary sex characteristics due to this• Mating systems…
