Gregarious Foraging in a Nocturnal Primate

这是一个试验性项目，将调查印度尼西亚一种夜间活动的小型灵长类动物--光谱迟滞的摄食模式。据推测，这些动物是群居的觅食动物。如果这是真的，那么接下来会有两个预测：个体不会在整个晚上随机相遇；2)个体在觅食时会被观察到在附近。将收集行为和位置数据来验证假设。实验动物将被驯化，设置陷阱，并戴上无线电项圈。将使用几个抽样程序来确保收集到关于动物行为和空间分布的适当数据。如果证明光谱迟滞是一种群居觅食者，将寻求进一步的支持，以确定这种行为的近端和远端原因。是捕食者的压力、资源的时间分布还是避免杀婴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?
