We tested for fire‐induced (5–6 years post‐fire) changes in the structure and functioning of the soil food web along a 3000‐km north–south transect across European Russia, spanning all major forest types in the northern hemisphere outside the tropics. The total biomass of the detrital food web, including microbes and invertebrates, was not affected by fire. However, fire reduced the biomass of microfauna and mites, but had no impact on mesofauna or macrofauna. Fire also reduced rates of carbon (C) mobilisation by soil biota. Our results demonstrate that fire‐induced shifts in soil food webs have significant short‐term effects on forest soil C cycling, but that these effects vary across forest types and geographic locations.

森林大火引起土壤食物网的短期变化，从而影响碳循环

我们测试了整个欧洲北半球3000公里南北横断面的火灾引起的（火灾后5-6年）土壤食物网的结构和功能的变化，该变化跨越了北半球所有主要森林类型热带。碎屑食物网的总生物量，包括微生物和无脊椎动物，不受火的影响。然而，火减少了微型动物和螨的生物量，但对中型动物或大型动物没有影响。火灾还降低了土壤生物群落中碳（C）的迁移速度。我们的结果表明，火在土壤食物网中引起的变化对森林土壤碳循环具有重大的短期影响，但这些影响因森林类型和地理位置而异。
