Aye-Aye (Daubentonia madagascariensis) Feeding Strategies at Ranomafana National Park, Madagascar: An Indirect Sampling Method
View through CrossRef
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.

Description:
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.
