“…Region 1 covered both V1 and V2 hypervariable regions, and region 2 spanned the V4 regions of the eukaryotic 18S rDNA sequences reported by Hugerth et al [38]. Both PCR target regions have been used in previous DNA barcode analyses of nematode communities using the next-generation sequencer Roche 454 [20,21,26,39] or Illumina MiSeq [22,23,25,27,28,40,41]. Regions 2 and 3 were newly examined in this study and spanned the V4 region and the V5-V7 regions, respectively ( Fig 1B).…”

“…These studies have shown that bacterial feeders, plant feeders, and fungivores often occupied significant fractions of the nematode communities in forest soils. A relatively high abundance of bacterial feeders has been commonly found; however, their proportions varied by the sampling sites and periods [58,62], age [56], and environmental status of the forests [25,52,55] or treatments such as clear-cut harvesting and fertilization [61,63]. Omnivores and predators were found in relatively minor fractions of soil nematodes in forest soils except in natural re-establishing subtropical forest [54] and coastal fir and pine forests [51,58].…”

“…The meadow steppe was treated as grassland with moderate disturbance of human activity due to the mowing each year (Cao et al 2019;Yan et al 2016). The grassland from forest-steppe ecotone was selected as the natural grassland with little disturbance and human activity (Du et al 2020). We hypothesized that grassland degradation will have negative influences on soil quality and soil biotic communities, with lower SQI index and diversity of soil biotic community observed in the degraded grassland compared with the meadow steppe and grassland from the forest-steppe ecotone.…”

“…Nitrogen enrichment caused by nitrogen deposition is one of the main reasons leading to species extinction and changes in species composition in grassland ecosystems (Zhang et al, 2014). Shifts in plant composition has an important mediation effect on soil bacteria, fungi and their consumers (Bezemer et al, 2010;Zhang et al, 2015;Du et al, 2020). Nematodes, as the most important microbial predators in soil, are good indicators for evaluating the structure and function of soil food webs because they are closely related to the soil environment and are sensitive to habitat disturbance (Yeates, 2003;Bardgett and van der Putten, 2014).…”
