目的寄生虫普遍存在且进化迅速。因此，它们通过影响其生物学的许多方面来代表作用于其宿主的主要选择力。人类也不例外，因为他们与动物共享许多寄生虫，一些最重要的爆发来自灵长类动物。虽然它似乎很重要，以了解寄生虫动态的因素，我们仍然缺乏一个明确的了解寄生的决定因素。在这项为期2年的研究中，我们确定了影响野生自由放养山海关（Mandrillus sphinx）种群中寄生虫模式的几个因素。方法我们探讨了季节因素（降雨量和温度）以及宿主特征（包括性别）的潜在影响、年龄、等级和生殖状态，对寄生虫丰富度。我们分析了12个寄生虫分类群中发现的870个粪便样本收集63个人。由于线虫和原生动物有不同的生命周期，我们分析了这两种类型的parasitesindependent.

ObjectivesParasites are ubiquitous and evolve fast. Therefore, they represent major selective forces acting on their hosts by influencing many aspects of their biology. Humans are no exception, as they share many parasites with animals and some of the most important outbreaks come from primates. While it appears important to understand the factors involved in parasite dynamics, we still lack a clear understanding of the determinants underlying parasitism. In this 2‐year study, we identified several factors that influence parasite patterns in a wild population of free‐ranging mandrills (Mandrillus sphinx).MethodsWe explored the potential impact of seasonal factors—rainfall and temperature—and host characteristics, including sex, age, rank, and reproductive status, on parasite richness. We analyzed 12 parasite taxa found in 870 fecal samples collected from 63 individuals. Because nematodes and protozoa have different life‐cycles, we analyzed these two types of parasites separately.ResultsContrary to other studies where humid conditions seem favorable to parasite development, we report here that rainfall and high temperatures were associated with lower nematode richness and were not associated with lower protozoa richness. In contrast, female reproductive status seemed to reflect the seasonal patterns found for protozoa richness, as early gestating females harbored more protozoa than other females. Sex and dominance rank had no impact on overall parasite richness. However, age was associated with a specific decrease in nematode richness.ConclusionOur study emphasizes the need to consider the ecological context, such as climatic conditions and habitat type, as well as the biology of both parasite and host when analyzing determinants of parasite richness.
