1999年，我们测量了生活在马达加斯加贝伦蒂保护区的101只野生环尾狐猴（狐猴）的体重。此外，我们统计了蜱虫的数量[血蜱（Rhipistoma） lemuris Hoogstraal, 1953]，寄生在他们的面部皮肤和外耳道。无论男性还是女性，体重在3岁之前都在增加。除了婴儿明显的例外，在体重上没有性别差异。在一个群体中，地位较高的成年雄性往往比地位较低的雄性更重。相比之下，女性的体重和她们的等级之间没有一致的相关性。在研究小组中，体重差异不大，但在感染面部皮肤和外耳道的蜱虫数量上存在显著差异。特别是，居住在研究区域廊道森林区域的狐猴群体表现出最小的体重值，并且严重感染了蜱虫。这种群体差异并不总是与研究组的生殖参数相关。在中度蜱虫侵染组中，蜱虫侵染成年雄虫和亚成虫的程度高于成年雌虫、幼虫和幼虫。
In 1999, we measured the body mass of 101 wild ring-tailed lemurs (Lemur catta) inhabiting the Berenty Reserve, Madagascar. In addition, we counted the number of ticks [Haemaphysalis (Rhipistoma) lemuris Hoogstraal, 1953] infesting their facial skin and external auditory meatuses. For both males and females, the body mass appeared to increase until the age of 3 years. With the apparent exception of infants, there were no sexual differences in body mass. Within a group, higher-ranked adult males tended to be heavier than lower-ranked males. In contrast, there was no consistent correlation between the body mass of females and their ranks. Among the study groups, there was a small difference in body mass and significant difference in the number of ticks infesting the facial skin and external auditory meatuses. In particular, lemurs of a group who inhabited an area of gallery forest in the study area exhibited the smallest values of body mass and were severely infested with ticks. Such group variations were not consistently correlated with the reproductive parameters of the study groups. In three groups moderately infested with ticks, ticks infested adult males and subadults more heavily than adult females, juveniles, and infants.
