Marginal value theorem

WebOptimal foraging theory has survived a number of criticisms and passed all the reasonable tests that one could apply to any theoretical approach. Some have criticized it for being on overly simplistic and unrealistic; but most significant conceptual paradigms develop iteratively, improving assumptions and refining models as new data comes to light. WebApr 4, 2024 · Charnov called the results the 'marginal value theorem'. The models were formulated mathematically, but their salient features are shown in graphic form in Figure 9.22. The primary assumption of the model is that an optimal forager will maximize its overall intake of a resource (usually energy) during a bout of foraging, taken as a whole.
