is an endemic tree growing only on eight mountain stands on the Greek island of Crete. The aim of this study was to determine the structure of the assemblages and analyze the diversity of the arachnid assemblages living on , an endemic tree species in Crete. Material for the analyses was collected from tree trunks, oftentimes covered by bryophytes or lichens. In the examined material, 85 taxa were recorded. The most numerous groups represented in the analyzed material were Acari, including representatives of the orders Mesostigmata (78 ind. of 18 spp.) and Oribatida (1056 ind. of 51 spp.). In the order Mesostigmata the species represented by the highest numbers of specimens were (15 individuals) and sp. (13), which is probably a species new to science. In turn, representatives of the order Oribatida were much more numerous, with (284) and (210) being identified in the largest numbers. Among the eight sampled localities, Gerakari (646 ind. and 50 spp.) and Omalos (409 ind. and 43 spp., respectively) had by far the richest assemblages. Statistical analyses confirmed the highly diverse character of the arachnid assemblages at the individual sites, which is a consequence not only of the varied numbers of arachnids found, but also of the presence of very rare species, such as , or . These results highlight the high species diversity of the arachnids found on but also suggest the lack of connectivity between the isolated and fragmented forest stands on Crete.
是一种仅生长在希腊克里特岛八座山上的特有树种。本研究的目的是确定生活在克里特岛特有树种上的蛛形纲动物群落的结构，并分析其多样性。分析材料取自树干，这些树干常常被苔藓植物或地衣覆盖。在所检查的材料中，记录了85个分类单元。分析材料中数量最多的类群是蜱螨亚纲，包括中气门目（18个物种，78只个体）和甲螨目（51个物种，1056只个体）的代表。在中气门目中，标本数量最多的物种是（15只个体）和sp.（13只），后者可能是一个新的科学物种。相比之下，甲螨目的代表数量要多得多，其中数量最多的是（284只）和（210只）。在八个采样地点中，杰拉卡里（646只个体和50个物种）和奥马洛斯（分别为409只个体和43个物种）的群落最为丰富。统计分析证实了各个地点蛛形纲动物群落具有高度多样性，这不仅是因为发现的蛛形纲动物数量不同，还因为存在非常稀有的物种，如、或。这些结果突出了在上发现的蛛形纲动物的高物种多样性，但也表明克里特岛上孤立且破碎的林分之间缺乏连通性。
