This study examines how range size affects intestinal parasite infections, and how such infections affect activity budgets in captive lemurs. There were no differences in parasite richness or intensity attributable to habitat type. However, there was a strong suggestion that parasite loads reduce activity levels.

三种自由放养与圈养狐猴（Lemur catta、Varecia rubra 和 Eulemur mongoz）肠道寄生虫感染和活动预算的比较

这项研究调查了范围大小如何影响肠道寄生虫感染，以及此类感染如何影响圈养狐猴的活动预算。由于栖息地类型不同，寄生虫丰富度或强度没有差异。然而，强烈建议寄生虫负荷会降低活动水平。
