Density, diversity and assemblage structure of Mesostigmata (cohorts Gamasina and Uropodina) were investigated in Scots pine forests differing in forest age (young: 9-40 years and mature: 83-101 years) in which wildfire occurred. This animal group belongs to the dominant acarine predators playing a crucial role in soil food webs and being important as biological control agents. In total, six forests (three within young and three within mature stands) were inspected in Puszcza Knyszyńska Forest Complex in May 2015. At each forest area, sampling was done from burned and adjacent control sites with steel cylinders for heat extraction of soil fauna. Data were analyzed statistically with nested ANOVA. We found a significant effect on mite density of both fire and forest age, with more mites in mature forests and control plots. In total, 36 mite taxa were identified. Mite diversity differed significantly between forest ages but not between burned versus control. Our study indicated that all studied forests are characterized by unique mite species and that the mite communities are dominated by different mite species depending on age forest and surface wildfire occurrence. Finally, canonical correspondence analysis ranked the mite assemblages from control mature, through burned young and burned mature, away from the control young.
在遭受过野火的不同林龄（幼龄林：9 - 40年；成熟林：83 - 101年）的苏格兰松林中，对中气门螨类（革螨亚目和尾足螨亚目）的密度、多样性和群落结构进行了调查。该动物类群属于优势螨类捕食者，在土壤食物网中起关键作用，作为生物防治剂也很重要。2015年5月，在克尼申斯卡森林保护区对总共六片森林（幼龄林中有三片，成熟林中也有三片）进行了检查。在每个林区，从火烧地和相邻对照地用钢筒采集土壤动物用于热提取。数据采用嵌套方差分析进行统计分析。我们发现火灾和林龄对螨类密度均有显著影响，成熟林和对照地中的螨类更多。总共鉴定出36个螨类分类单元。螨类多样性在不同林龄间差异显著，但在火烧地和对照地之间无显著差异。我们的研究表明，所有研究的森林都有独特的螨类物种，并且螨类群落因林龄和地表野火的发生情况而由不同的螨类物种主导。最后，典范对应分析将螨类群落从对照成熟林、火烧幼龄林和火烧成熟林依次排列，远离对照幼龄林。
