Optimal foraging the marginal value theorem

Webd) The entire foraging trip takes approximately 25 minutes, which includes both the time spent traveling to the patch and the time spent in the patch foraging. e) The optimal harvest rate is around 0.8 units per minute, which is the point where the slope of the resource intake curve is highest. Webwhether the behavior or the organism is strictly optimal (8–10). Arguably one of the most influential contributions to optimal foraging theory was the marginal value theorem (MVT) (10, 13, 14). MVT uses an optimality framework to predict how organ-isms should allocate foraging effort to patches of differing
