Generality of the Size-Distance Relation in Models of Optimal Feeding

摘要: If pursuit or provisioning time is unrelated to prey size, the following size-distance properties are expected for a variety of prey-handling functions. 1. The best size increases with distance. 2. For given values profit (measured as energy per unit time), changes less distance, larger prey. 3. range sizes taken shifts toward sizes, distance increases. these effects can be reversed.
