"Optimal foraging: The marginal value theorem" by Eric Charnov
The marginal value theorem (MVT) is an optimality model that usually describes the behavior of an optimally foraging individual in a system where resources (often food) are located in discrete patches separated by areas with no resources. Due to the resource-free space, animals must spend time traveling … See more All animals must forage for food in order to meet their energetic needs, but doing so is energetically costly. It is assumed that evolution by natural selection results in animals utilizing the most economic and efficient strategy to … See more Humans A common illustration of the MVT is apple picking in humans. When one first arrives at a new apple tree, the number of apples picked per minute is … See more • Diminishing returns • Optimal foraging theory See more As animals forage in patchy systems, they balance resource intake, traveling time, and foraging time. Resource intake within a patch diminishes with time, as shown by the solid curve in the graph to the right. The curve follows this pattern because resource intake is … See more Many studies, such as the examples presented above, have shown good qualitative support for predictions generated by the … See more WebMar 24, 2009 · 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 organisms should allocate foraging effort to patches of differing quality before leaving, and by extension, predicts broad scale patterns of movement across a landscape. healtht lunch places lee\\u0027s summit mo

WebEric Lee Charnov (born October 29, 1947) is an American evolutionary ecologist. He is best known for his work on foraging, especially the marginal value theorem, and life history theory, especially sex allocation and scaling/allometric rules.
