Figure 2.

The optimal reserve-dependent strategy in each of three environments when the animal is building up reserves for reproduction. In each environment, two of the three options given in table 2 are available. The threshold value of reserves needed for reproduction is x=90. (When options A and C are available, the optimal strategy is to switch back to A when x goes above 83 since energy that would take the reserves above the threshold for reproduction is lost.) The dotted lines indicate the range of reserves between which intransitive choice is predicted.
