WebApr 1, 1976 · CONCLUSIONS A rule is proposed for the movement of an optimal predator through an environment where food is found in patches, and time is expended in movement between patches. The theorem is rather general and should be useful where predators … The behaviour of coccinellid larvae on plants was studied.

WebSep 9, 2005 · The optimal‐foraging model is based on the marginal value theorem (MVT). The robust‐satisficing model developed here is an application of info‐gap decision theory. The info‐gap robust‐satisficing model relates to the same circumstances described by the MVT. We show how these two alternatives translate into specific predictions that at some … The marginal value theorem is a type of optimality model that is often applied to optimal foraging. This theorem is used to describe a situation in which an organism searching for food in a patch must decide when it is economically favorable to leave. While the animal is within a patch, it experiences the law of diminishing returns, where it becomes harder and harder to find prey as time g…
