亚马逊印第安人的低人口密度和临时定居通常被解释为适应了一种动物群，这种动物群提供的蛋白质资源有限，而且很快就会被狩猎消耗殆尽。横跨亚马逊西北部一个定居点10年生命周期的数据表明，狩猎产量的变化是由pecary（塔亚苏pecariandT）的时间变化引起的。（Tajacu）杀戮似乎与当地人口规模无关。10年后，狩猎成功率仍然很高，大多数猎物的杀戮率并不意味着枯竭。一系列的环境因素解释了观察到的早期定居迁移。
The low population densities and impermanent settlements of Amazonian Indians are often interpreted as adaptations to a fauna that offers limited protein resources and is rapidly depleted by hunting. Data spanning the 10-year life cycle of one northwestern Amazonian settlement show that variations in hunt yields result from temporal variations in peccary (Tayassu pecariandT. tajacu) kills that appear extrinsic to native population size. After 10 years, hunting success remained high and the kill rates for most prey did not suggest depletion. An array of environmental factors accounts for the incipient settlement relocation observed.
