尸体的埋葬导致节肢动物活动减少和殖民模式中断。在这里，螨类群的分布和多样性进行了研究，在浅埋猪尸体（猪）的分解阶段。从三个猪浅坟中共收集了300只螨（88种），而从相同深度的对照（裸露）土壤样品中收集了129只螨（46种）。阿卡里较高的类群和家庭的演替模式进行了观察，和物种丰富度和生物多样性波动整个分解，而活跃的腐烂表现出最大的生物多样性。中气门螨是最丰富的“尸体土壤”的寄生螨的丰度有显着差异，而甲螨（真正的土壤螨）是最丰富的控制土壤。某些螨种与腐烂阶段显着相关：Cornigamalphum lunaris与“膨胀”，Gamasodes spiniger与“活跃”，Eugamalphum sp.和Lorryia reticulata与“先进”，Macrocheles matrius和Ramusella clavipectinata在“干”。Scheloribates laevigatus是一个标记裸露的土壤在一个浅的深度和Vulgoramartillemberti的掩埋分解，而不是特定的任何腐烂阶段。对头、躯干和后躯螨类组合的分析表明，外翻寄生螨和M. matrius被吸引到大腿下方，而L.网状到头部下方。本研究强调了螨类作为分解及其阶段的指示种的价值，证实了（1）埋藏遗骸上的阿卡里的演替和（2）身体区域的种特异性。在线版本包含补充材料，可通过10.1007/s10493-021-00663-x获得。
The burial of a cadaver results in reduced arthropod activity and disruptions in colonisation patterns. Here, the distribution and diversity of mite taxa was studied across decomposition stages of shallowly buried pig carcasses (Sus scrofa domesticus). In total 300 mites (88 species) were collected from three pig shallow graves compared to 129 mites (46 species) from control (bare) soil samples at the same depth. A successional pattern of Acari higher taxa and families was observed, and species richness and biodiversity fluctuated throughout decomposition, whereas active decay showed the greatest biodiversity. Mesostigmata mites were the most abundant in ‘cadaver soils’ with a significant difference in the abundance of Parasitidae mites, whereas Oribatida mites (true soil mites) were the most abundant in control soils. Certain mite species were significantly associated with decay stages: Cornigamasus lunaris with ‘bloated’, Gamasodes spiniger with ‘active’, Eugamasus sp. and Lorryia reticulata with ‘advanced’, and Macrocheles matrius and Ramusella clavipectinata in ‘dry’. Scheloribates laevigatus was a marker of bare soil at a shallow depth and Vulgoramasus remberti of buried decomposition, not specific to any decay stage. Analysis of mite assemblages associated with head, torso and posterior body showed that Parasitus evertsi and M. matrius are attracted to beneath the thighs, whereas L. reticulata to beneath the head. This study highlights the value of mites as indicator species of decomposition and its stages, confirming (1) a succession of Acari on buried remains and (2) species specificity to body regions.
