【摘要】 介绍动物觅食行为的建模。首先考察觅食动物的搜寻、处理所需时间和能量等基本因素如何影响食饵的选择,建立一个初等模型,使觅食动物的净能量获取率最大,并可预测动物的"最优"食物,然后考虑食饵识别时间、食物地块和觅食中心位置等因素来修正、改进这个模型。最后,用一些实验数据来解释这些模型。更多还原

【Abstract】 This paper is an introduction to the modeling of animal foraging behavior.We look first at how such basic factors as search and handling times and energy content may affect prey choice by foraging animals.We construct an elementary model that maximizes the net energy intake rate of the forager and that can predict"optimal"diets of animals.We then modify and refine this model to take into account factors such as prey recognition time,food patches,and central place foraging.Data from several experiments illustrate all the models.更多还原
