Gregarious Foraging in a Nocturnal Primate

这是一个试点项目，将调查印度尼西亚一种小型夜行灵长类动物的摄食模式；光谱眼镜猴。据推测，这些动物是群居的觅食者。如果这是真的，那么就有两个预测：一是个体之间不会在夜间随意相遇；二是个体在觅食时会在附近被观察到。将收集行为和位置数据来验证这些假设。测试动物将被驯化、困住并戴上无线电项圈。将采用若干抽样程序，以确保收集有关动物行为和空间分布的适当数据。如果证明光谱眼镜猴是群居觅食者，将寻求进一步的支持，以确定这种行为的近因和远因。是捕食者的压力、资源的时间分布还是避免杀婴行为决定了这种觅食行为？

This is a pilot project that will investigate the feeding patterns of a small, nocturnal primate of Indonesia; the spectral tarsier. It is hypothesized that these animals are gregarious foragers. If this is true, then two predictions follow: that individuals will not encounter one another at random throughout the night and 2) that individuals will be observed in proximity while foraging. Both behavioral and positional data will be gathered to test the hypotheses. Test animals will be habituated, trapped and radio collared. Several sampling procedures will be used to assure appropriate data will be gathered on the behavioral and spatial distribution of the animals. If it is demonstrated that the spectral tarsier is a gregarious forager further support will be sought in order to determine the proximate and distal causes of this behavior. Is it predator pressure, the temporal distribution of resources or infanticide avoidance that determines this foraging behavior?
