Theory 17/Exploration vs Exploitation/Foraging

Leaving Early Costs Food

The claim

The optimal time to leave a patch trades the food remaining against the value of discovering a better one, so the leaving threshold depends on habitat quality.

01Mechanism

Marginal value theorem: leave when the current rate falls to the average rate, which rises with habitat quality.

02Prediction

Residence time should fall as habitat quality rises.

03Refutation

Residence time independent of habitat would remove the trade-off.
