The average life-time intake rate (the intake rate average over the whole period of the simulation) as a function of the initial estimate of the environment quality for foragers with memory but without learning capabilities.

<p>The solid line represents a forager with a long time-frame of foraging (i.e., a simulation which ended after the forager consumed 10,000 food units). The dashed line represents a forager with an intermediate time-frame (1,000 food units), and the dotted line represents a forager with a short time-frame (100 food units). The dotted vertical line indicates on the average quality of the environment. Error bars represent one standard deviation.
