在这项研究中，我们专注于在Ranomafana国家公园，马达加斯加的指猴种群。从2008年8月至12月，我们测试了如何aye-aye喂养的存在/不存在的果和非果橄榄树的影响。枯木喂养痕迹被用作橄榄喂养的证据代理。我们列举了枯木喂养痕迹在20个地点，10与橄榄，10没有。每个地点包含两个样带（80 m长× 20 m宽），总面积为5.6公顷。与非橄榄位置相比，橄榄位置的摄食痕迹结果不显著（Z =-1.926，p = 0.083）;然而，当比较果和非果橄榄位置时，摄食痕迹结果显著（Z =-2.417，p = 0.016）。这些结果突出了橄榄在aye-ayes饮食中的重要性，并展示了这种资源的分布可能会影响aye-ayes的觅食行为。
In this research, we focused on aye-aye populations in Ranomafana National Park, Madagascar. From August to December 2008, we tested how aye-aye feeding was influenced by presence/absence of both fruiting and non-fruiting Canarium trees. Deadwood feeding traces were used as a proxy for evidence of Canarium feeding. We enumerated deadwood feeding traces in 20 locations, 10 with Canarium, 10 without. Each location contained two transects (80 m L × 20 m W) for a total area of 5.6 ha. Feeding trace results for Canarium locations compared to non-Canarium locations were not significant (Z = –1.926, p = 0.083); however, feeding trace results were significant when comparing fruiting and non-fruiting Canarium locations (Z = –2.417, p = 0.016). These results highlight the importance of Canarium in the diet of aye-ayes and demonstrate how the distribution of this resource may influence the foraging behavior of aye-ayes.
