Theoretical Population Biology ... WebNov 1, 2000 · A number of theoretical models have been proposed in order to predict the optimal residence time a female should allocate to each visited patch. The Marginal Value Theorem (MVT) developed by Charnov is based on the assumption that females, foraging on depleting patches of hosts, should experience diminishing returns. In such a condition, … WebOptimal foraging assumes that natural selection has resulted in foraging behavior that maximizes fitness, while taking into account the dependence of energy intake rate on the forager’s ability to detect, capture, and handle each prey item. chip solitaire
