Document Summary
Some q on midterm based on stats in lab (mostly 1st lab). Basic questions: use fitness benefit when discussing adaptive ness of behavior. An increase in fitness is relative to other variants of the behavior or no behavior: fitness benefit has to be >0 and hopefully greater than fitness cost to be adaptive. No weather conditions to control or other environmental variations. Can easily manipulate environment to get effect of enviro on behavior. Get a good estimate of effect of genes: genes vs. environment advantages. Unnatural interactive effects of genes vs. environment are avoided (i. e. lab effects) Study the effects of predation on multiple-mating in guppies. Set up tank w/ male and female guppies, from pop w/ either large or no predation. Ignores details of water current, refuges, and pop density: unnatural. Collect females from many rivers w/ either lager or no predation.
