概述1.现有的理论认为，当资源有限且可防御时，领土范围将发生演变，但可防御性很少被定量分析。2.我们认为可防御性取决于动物为了发现潜在入侵者而监控其范围边界的能力，并引入可防御性指数(D)，即观察到的每日路径长度(D)与等于动物活动区域面积的圆的直径(d‘)的比率。这一指数只对极端偏离圆形的情况敏感。3.回顾有关灵长类测距的文献，所有有数据的地区组的指数都在1.0或更高，很少有非地区物种的指数大于或等于1.0。4.对日路径长度与摄食组重量和食物中的叶的关系进行回归分析表明，摄食组的重量和食物中的叶都可以解释日路径长度的变化，对于给定的组重量和食物，地区组和非地区组在日变化范围上没有差异。
Summary1.Existing theory suggests that territoriality will evolve when resources are limited and defendable, but defendability has seldom been analyzed quantitatively.2.Here we argue that defendability depends on the ability of an animal to monitor the boundaries of its range in order to detect potential intruders and introduce an index of defendability (D) which is the ratio of observed daily path length (d) to an area equal to the diameter (d′) of a circle with area equal to home range area of the animal. This index is sensitive only to extreme deviation from circular shape.3.Review of the literature on primate ranging reveals that all territorial groups for which data are available have an index of 1.0 or greater, and that few nonterritorial species have an index of 1.0 or greater.4.Regression analysis of the relationship of daily path length to feeding group weight and foliage in the diet reveals that both feeding group weight and foliage in the diet account for a large proportion of the variance in daily path length, and that territorial and nonterritorial groups do not differ in day range for a given group weight and diet.
