WebApr 19, 2024 · Figure 4: Marginal value theorem for optimal virulence. The ESS [evolutionarily stable strategy] virulence occurs where a line rooted at the origin is tangent to the curve that relates β to δ. Two curves are depicted. The first curve shows a pathogen in which transmissibility increases relatively rapidly with mortality. 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.

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
