Abstract The red oak (Quercus rubra L.) is a woody plant brought to Europe from North America for its decorative value and high tolerance to frost and pollution. The species has been planted for the reclamation of brownfield sites, and introduced to commercial forests to enrich local biodiversity. Although in Poland its presence was associated with depauperation of local flora, its invasive status is still under discussion. The aim of this study was to determine the impact of red oak stands on Acari communities (Oribatida, Mesostigmata, Astigmata, Prostigmata). In the detailed analyses we focused on the Oribatida species, one of the best bioindicators of soil condition. The presence of the red oak was compared to the pedunculate (native) oak, also planted on poor acid soils. The research design included oak stands introduced in commercial forests, divided into two groups: young and old. A total number of 240 soil samples were collected, and 173 species of oribatid mites were identified. A low proportion of the Oribatida species typical for the Palearctic region, specific to deciduous forests, with sexual reproduction and belonging to the trophic level of secondary decomposers, significantly distinguished the old alien oaks from old native oaks. The results presented in this work are one of the few which concern the reaction of soil oribatid mite community to plant invasions, and provide evidence of the harmful impact of these alien tree species, which can be overlooked in short-term studies.

Oribatid 螨（Acari：Oribatida）群落揭示了红橡木（Quercus rubra L.）对波兰商业林土壤动物群的负面影响

摘要 红橡木（Quercus rubra L.）是一种从北美传入欧洲的木本植物，具有观赏价值和抗霜冻和抗污染的能力。该物种已被种植用于开垦棕地，并引入商业森林以丰富当地的生物多样性。尽管在波兰，它的存在与当地植物群的枯竭有关，但其入侵状态仍在讨论中。本研究的目的是确定红橡木林分对 Acari 群落（Oribatida、Mesostigmata、Astigmata、Prostigmata）的影响。在详细分析中，我们专注于 Oribatida 物种，这是土壤状况的最佳生物指标之一。将红橡木与同样种植在贫酸性土壤上的有花序橡木进行比较。研究设计包括在商业林中引入的橡木林分，分为两组：青年组和老年组。共采集土壤样品240份，鉴定173种类螨。低比例的古北地区典型的 Oribatida 物种，特定于落叶林，有性繁殖并属于次级分解者的营养水平，显着区分了古老的外来橡树和古老的本土橡树。这项工作中提出的结果是为数不多的涉及土壤 oribatid mite 群落对植物入侵的反应的结果之一，并提供了这些外来树种的有害影响的证据，这些在短期研究中可能会被忽略。低比例的古北地区典型的 Oribatida 物种，特定于落叶林，有性繁殖，属于次级分解者的营养水平，显着区分了古老的外来橡树和古老的本土橡树。这项工作中提出的结果是为数不多的涉及土壤 oribatid mite 群落对植物入侵的反应的结果之一，并提供了这些外来树种的有害影响的证据，这些在短期研究中可能会被忽略。低比例的古北地区典型的 Oribatida 物种，特定于落叶林，有性繁殖，属于次级分解者的营养水平，显着区分了古老的外来橡树和古老的本土橡树。这项工作中提出的结果是为数不多的涉及土壤 oribatid mite 群落对植物入侵的反应的结果之一，并提供了这些外来树种的有害影响的证据，这些在短期研究中可能会被忽略。
