捕食者的嗅觉线索，如粪便，已知会引起动物的反捕食反应（例如，避免，活动）。然而，到目前为止，在灵长类动物的嗅觉捕食识别的信息很少。我们测试了不同的捕食者类别（历史马达加斯加捕食者和引进的捕食者）和马达加斯加nonpredators（控制）的粪便的气味是否会诱导反捕食行为在圈养出生，捕食者天真的灰鼠狐猴。在一项嗅觉捕食者实验中，一只鼠狐猴被暴露在一种特定的气味中，固定在一个优选的位置，在那里动物被训练以获得奖励。对鼠狐猴对相应刺激类别的行为进行录像和量化。结果表明，当气味属于捕食者时，鼠狐猴会避开气味出现的地方。他们的反应显着增强活动时，暴露于食肉动物的气味相比，那些nonpredatory控制。这些发现支持嗅觉捕食者识别的遗传倾向，这可能是基于对肉类消化代谢物的感知。
Olfactory cues of predators, such as feces, are known to elicit antipredator responses in animals (e.g., avoidance, activity). To date, however, there is little information on olfactory predator recognition in primates. We tested whether the odor of feces of different predator categories (historical Malagasy predators and introduced predators) and of Malagasy nonpredators (control) induces antipredator behavior in captive born, predator-naïve gray mouse lemurs. In an olfactory predator experiment a mouse lemur was exposed to a particular odor, fixed at a preferred location, where the animal was trained to get a reward. The behavior of the mouse lemur toward the respective stimulus category was videotaped and quantified. Results showed that mouse lemurs avoided the place of odor presentation when the odor belonged to a predator. They reacted with a significantly enhanced activity when exposed to odors of carnivores compared to those of nonpredatory controls. These findings are in favor of a genetic predisposition of olfactory predator recognition that might be based on the perception of metabolites from meat digestion.
