Native forests have been replaced by forestry plantations worldwide, impacting biodiversity. However, the effect of this anthropogenic land-use change on parasitism is poorly understood. One of the most important land-use change in Chile is the replacement of native forests by Monterey pine () plantations. In this study, we analyzed the parasitism (presence and prevalence) of intestinal helminths from fecal samples of wild rodents in three habitat types: native forests and adult and young pine plantations in central Chile. Small mammals were sampled seasonally for two years, and a total of 1091 fecal samples from seven small mammal species were analyzed using coprological analysis. We found several helminth families and genera, some of them potentially zoonotic. In addition, new rodent-parasite associations were reported for the first time. The overall helminth prevalence was 16.95%, and an effect of habitat type on prevalence was not observed. Other factors were more relevant for prevalence such rodent species for sp. and season for sp. Our findings indicate that pine plantations do not increase helminth prevalence in rodents compared to native forests.
全球范围内，原生森林已被人工林所取代，这对生物多样性产生了影响。然而，这种人为土地利用变化对寄生现象的影响却鲜为人知。智利最重要的土地利用变化之一就是原生森林被辐射松人工林所取代。在本研究中，我们分析了智利中部三种栖息地类型（原生森林以及成年和幼年辐射松人工林）中野生啮齿动物粪便样本里肠道蠕虫的寄生情况（存在情况和流行率）。对小型哺乳动物进行了为期两年的季节性采样，并使用粪便学分析方法对来自7种小型哺乳动物物种的总共1091份粪便样本进行了分析。我们发现了几个蠕虫科和属，其中一些可能是人畜共患病原体。此外，首次报道了新的啮齿动物 - 寄生虫关联。蠕虫的总体流行率为16.95%，未观察到栖息地类型对流行率有影响。其他因素对流行率更为重要，例如对于 属物种而言是啮齿动物物种，对于 属物种而言是季节。我们的研究结果表明，与原生森林相比，辐射松人工林不会增加啮齿动物体内蠕虫的流行率。
