MEASURING BEHAVIORWhy construct an ethogram?Use data to construct and tests hypothesisWhat are the steps involved in constructing an ethogram? How do they compare to the stages of the scientific method?Observe and define discrete behaviors-group into categoriesMeasure and record over time intervalsNote context of behaviors (age, weather, season, gender, etc).What are 3 behavioral measures used in the Junco studies described in the movie?Territorial protection, courting new mates, and caring for youngHow did testosterone impact the mating behavior of the experimental males (added testosterone) when compared to the control males?Made more aggressive, territorial, and lowered faithfullnessWhy was DNA analysis used in conjunction with the experimental manipulation and what did it show?More accurate assessment of behaviorsIf the juncos experience particularly difficult conditions during a breeding season, make a prediction as to whether the offspring from higher or lower Tmales will survive best. Support your prediction with data presented in the movie.Lower testosterone-more parental careDescribe one of the 2 example studies we covered in lecture by identifying the rationale, methods, experimental results, and conclusions of the study.Increased test. Levels increase reproductive rates but lower offspring fitnessAn optic sense can be replaces by an olfactory senseHow did researchers translate behaviors into quantitative values (ie, numbers) in the junco and crayfish studies?What are some ways that experimenters can quantitatively address individual differences in behavior among animals?Representative pop sizes and looking at repeated
