Population Consequences of Foraging Behavior

这是一项关于动物觅食行为的理论研究，旨在研究猎物的斑块分布对觅食的影响。一种几乎最优的觅食策略将被用来确定猎物在不同猎物密度下的定位速度。当斑块被最优觅食者利用时，猎物分布的变化，即通过重新访问斑块发现猎物的比率，也将被确定。将找到最优和几乎最优的策略，并计算它们在燕麦最优觅食的一般随机模型的特定版本中所能达到的猎物发现速度。功能反应的形式决定了某一版本的Lotka-Volterra捕食者-食饵模型是否稳定。斑块开发的效果对于确定维持觅食区域和划分资源的价值是重要的。

This is a theoretical study of animal foraging behavior that would examine the effect of patchy distribution of prey on foraging. An almost optimal foraging strategy will be used to determine the rate of locating prey as it changes under different prey densities. The changes in prey distribution when patches are exploited by an optimal forager, the rate of finding prey by revisiting patches, will also be determined. The optimal and almost-optimal strategies will be found and the rates of finding prey that they would achieve for a particular version of Oaten's general stochastic model of optimal foraging will be calculated. The form of the functional response determines whether a certain version of the Lotka-Volterra predator-prey model is stable. The effect of patch exploitation is important in determining the value of maintaining feeding territories and of partitioning resources.
