This paper presents an original palaeoparasitological study performed on samples from a sedimentary core in a peat bog (Asi Gonia, White Mountains, Crete, Greece). The aim of the study is to test the preservation and concentration of parasitic remains in peat sediments, to discuss animal presence around the site throughout the record, and to compare the results with other biomarkers of environmental history. In this aim, 22 sediment samples distributed between the Roman period and the present were processed and the residues were observed under light microscopy in search of parasitic markers (microscopic eggs or oocysts). The majority of the samples (86.4%) tested positive for the presence of helminth eggs. Several taxa were observed throughout the studied period, including Trichuris sp., Ascaris sp., Capillaria sp., Fasciola sp., Paramphistomum sp. and Macracanthorhynchus sp. The assemblage of parasite markers changes throughout the record and the variations show close correlations with previously published grazing indicators (fungal spores) and vegetation changes (pollen grains). This study sheds lights on animal associations and changing environments in the watershed over the past 2000 years. Indeed, we detected three main phases consisting of: Roman animal herding with pigs in an evergreen oak forest, then a more irregular but almost constant presence of ruminants during a second Byzantine and modern phase in a heather maquis landscape and, finally, present-day grazing in a phrygana/steppe landscape. These results highlight how palaeoparasitology can contribute to multi-proxy approaches in peat bog sedimentary sequences.

泥炭沼泽中的古代寄生虫：对过去 2000 年克里特岛动物存在和畜牧业的新见解

本文介绍了对泥炭沼泽（Asi Gonia，白山，克里特岛，希腊）中沉积岩心样本进行的原始古寄生虫学研究。该研究的目的是测试泥炭沉积物中寄生虫残留物的保存和浓度，讨论整个记录中该地点周围的动物存在，并将结果与​​环境历史的其他生物标志物进行比较。为此，对分布在罗马时期和现在之间的 22 个沉积物样本进行了处理，并在光学显微镜下观察残留物以寻找寄生标记（微观卵或卵囊）。大多数样本 (86.4%) 的蠕虫卵检测呈阳性。在整个研究期间观察到了几种分类群，包括鞭毛虫、蛔虫、毛细血管、片形藻、寄生菌。和 Macracanthorhynchus sp。寄生虫标记的组合在整个记录中都发生了变化，这些变化显示出与先前公布的放牧指标（真菌孢子）和植被变化（花粉粒）密切相关。这项研究揭示了过去 2000 年来流域中的动物协会和不断变化的环境。事实上，我们发现了三个主要阶段，包括：罗马动物在常绿橡树林中与猪一起放牧，然后在第二个拜占庭和现代阶段在石南花的景观中出现更不规则但几乎恒定的反刍动物，最后是现代在弗里加纳/草原景观中放牧。这些结果突出了古寄生虫学如何有助于泥炭沼泽沉积序列中的多代理方法。寄生虫标记的组合在整个记录中都发生了变化，这些变化显示出与先前公布的放牧指标（真菌孢子）和植被变化（花粉粒）密切相关。这项研究揭示了过去 2000 年来流域中的动物协会和不断变化的环境。事实上，我们发现了三个主要阶段，包括：罗马动物在常绿橡树林中与猪一起放牧，然后在第二个拜占庭和现代阶段在石南花的景观中出现更不规则但几乎恒定的反刍动物，最后是现代在弗里加纳/草原景观中放牧。这些结果突出了古寄生虫学如何有助于泥炭沼泽沉积序列中的多代理方法。寄生虫标记的组合在整个记录中都发生了变化，这些变化显示出与先前公布的放牧指标（真菌孢子）和植被变化（花粉粒）密切相关。这项研究揭示了过去 2000 年来流域中的动物协会和不断变化的环境。事实上，我们发现了三个主要阶段，包括：罗马动物在常绿橡树林中与猪一起放牧，然后在第二个拜占庭和现代阶段在石南花的景观中出现更不规则但几乎恒定的反刍动物，最后是现代在弗里加纳/草原景观中放牧。这些结果突出了古寄生虫学如何有助于泥炭沼泽沉积序列中的多代理方法。
