The main objective of the study was to analyse, for the first time in Romania, the relationships between five experimental grasslands and Mesostigmata fauna, considering: (1) the structural differences between mite communities; (2) the variations in some important abiotic factors (vegetation cover, soil temperature, soil moisture content, pH, soil resistance at penetration); and (3) the influence of these abiotic factors on the structures of Mesostigmata mite communities and the dispersal rates of these communities between the investigated plots. In total, 250 soil samples were analysed in July 2017, revealing the presence of 30 species, with 1163 individuals. Using the multivariate analysis, we observed that each experimental plot was defined by characteristic environmental conditions, i.e., vegetation cover, soil moisture content, and soil temperature differed significantly between the experimental grasslands. Each experimental plot was characterised by a specific indicator species and population parameters (numerical abundance and species richness). The effects of these soil variables were even demonstrated at species level: , and were influenced by vegetation cover, and by soil temperature. The dispersal rates of mite communities from one plot to another were higher in the grasslands, where there were euconstant-constant species.
本研究的主要目的是首次在罗马尼亚分析五个实验性草地与中气门螨类动物群之间的关系，具体考虑以下方面：（1）螨类群落之间的结构差异；（2）一些重要非生物因素（植被覆盖度、土壤温度、土壤湿度、pH值、土壤穿透阻力）的变化；（3）这些非生物因素对中气门螨类群落结构以及这些群落在调查样地之间扩散速率的影响。2017年7月共分析了250个土壤样本，发现有30个物种，共1163个个体。通过多变量分析，我们观察到每个实验样地由特定的环境条件界定，即实验性草地之间的植被覆盖度、土壤湿度和土壤温度存在显著差异。每个实验样地都有特定的指示物种和种群参数（数量丰度和物种丰富度）。这些土壤变量的影响甚至在物种层面也得到了体现： 、 和 受植被覆盖度影响， 和 受土壤温度影响。在具有常栖 - 恒栖物种的草地中，螨类群落从一个样地到另一个样地的扩散速率更高。
