任何捕食者的进化适应性，无论是捕捉昆虫的蜘蛛还是捕猎水牛的狮子，在很大程度上取决于其饮食的质量和数量。捕食策略是由自然选择形成和完善的，以在广泛的生态限制范围内（例如，猎物密度、栖息地）最大限度地增加营养摄入，同一物种在其地理分布的极端情况下可能存在巨大差异。在这些限制条件下，寻找和收集食物的基本任务从根本上影响了物种的间距模式和社会系统的结构。
The evolutionary fitness of any predator, whether it is a spider catching insects or a lion hunting buffalo, depends largely on the quality and quantity of its diet. Predatory strategies are shaped and refined by natural selection to maximize nutrient intake within the bounds of a wide range of ecological constraints (e.g., prey density, habitat) that may differ dramatically for the same species at the extremes of its geographical distribution. The basic task of finding and gathering food under these constraints fundamentally affects a species’ spacing patterns and the structure of its social systems.
