The European beech ( L.) is a tree species common throughout Europe, with the eastern boundary of its range extending across Poland. Samples were collected in several microhabitats of beech stands (e.g., leaf litter, rotting wood, moss growing on tree stumps) in the Wronie Forest Reserve. The aim of this study was to determine the effect of microhabitat conditions found in beech forests on the diversity of mite assemblages and their species richness. The collected samples comprised a total of 144 identified species (78 species of Oribatida, 66 species of Mesostigmata), represented by 74,433 mite individuals (71,124 Oribatida and 3309 Mesostigmata). All the analyzed microhabitats varied in terms of their mite assemblages. The highest number of species was identified in moss on beech stumps (72 species-53 Oribatida and 19 Mesostigmata) and in samples collected from beech litter (68 species-48 Oribatida and 20 Mesostigmata). The most numerously represented species in the analyzed material was , which was classified to superdominants in moss on beech stumps and moss on beech trunks (0.5 and 2.0 m), which were the most similar microhabitats. In contrast, mite assemblages in rotting wood and marsh litter differed greatly.
欧洲山毛榉（Fagus sylvatica L.）是一种在欧洲广泛分布的树种，其分布范围的东部边界横跨波兰。样本采集于弗罗涅森林保护区山毛榉林分的几个微生境（如落叶层、腐朽木材、树桩上生长的苔藓）。本研究的目的是确定山毛榉林中发现的微生境条件对螨类群落多样性及其物种丰富度的影响。采集的样本总共包含144个已鉴定物种（78种甲螨目、66种中气门目），由74433只螨个体代表（71124只甲螨目和3309只中气门目）。所有分析的微生境在螨类群落方面各不相同。在山毛榉树桩上的苔藓（72种——53种甲螨目和19种中气门目）以及从山毛榉落叶层采集的样本（68种——48种甲螨目和20种中气门目）中鉴定出的物种数量最多。分析材料中数量最多的物种是 ，它在山毛榉树桩上的苔藓以及山毛榉树干上（0.5米和2.0米处）的苔藓中被归类为超优势种，这两个微生境最为相似。相比之下，腐朽木材和沼泽落叶层中的螨类群落差异很大。
