Given what you know at this point about marine iguanas and the abiotic effects of enso, develop two possible directions of research that liz should pursue to understand exactly why the iguanas suffered such a high mortality. keep in mind that you need to consider indirect effects. while environmental temperature does change metabolic rates of ectotherms, the iguanas are exposed to a wide range of temperatures as they feed and bask on the lava. direct mortality in response to a temperature change of a couple of degrees is unlikely. (3 points possible)
possible research direction one:
possible research direction two:
choose one of those directions of research and determine what data you would need to find to support your ideas. (2 points possible)
design an experiment that would you collect the data you have identified in question four. identify your independent variable(s), dependent variable(s), treatments, and control. (5 points possible)
what conclusions do you think liz made about the cause of population declines in marine iguanas?
