土壤无脊椎动物和微生物是凋落物分解的两个主要驱动力。尽管无脊椎动物和微生物在生物地球化学土壤循环和土壤食物网中的重要性已经得到了研究，但与其他生物相比，无脊椎动物对真菌的影响还没有得到很好的了解。在这项工作中，我们研究了土壤无脊椎动物对真菌的影响，这是养分循环研究中不可忽视的因素。结果表明，等足类动物对白腐菌的放牧具有传递性和持久性。被放牧的真菌出现了“补偿性”生长。放牧后真菌生物量增加。放牧增加了与养分循环有关的酶的活性。酶谱图显示，放牧区酶热点区和酶活性显著增加。结果表明，无脊椎动物放牧能显著提高未放牧区真菌生物量和酶活性，加速凋落物分解。无脊椎动物的放牧效应对促进森林生态系统的养分循环具有重要作用。本研究对揭示土壤无脊椎动物、真菌与土壤生物地球化学循环的关系具有一定的参考意义。
Soil invertebrates and microorganisms are two major drivers of litter decomposition. Even though the importance of invertebrates and microorganisms in biogeochemical soil cycles and soil food webs has been studied, the effects of invertebrates on fungi are not well understood compared to other organisms. In this work, we investigated the effects of soil invertebrates on fungi as a factor that cannot be ignored in the study of nutrient cycling. The result showed the grazing of isopods on white-rot fungi was transitive and persistent. The grazed fungi appeared “compensatory” growing. The biomass of fungi increased after grazing. The activities of enzymes associated with nutrient cycling were increased under grazing. The zymography images showed the enzyme hotspots and activities also increased significantly in the grazing area. The results suggest that invertebrate grazing can significantly increase the fungal biomass and enzyme activity, accelerating litter decomposition in the unreached grazer area. The grazing effects of invertebrate plays an important role in promoting the nutrient cycling of the forest ecosystem. We believe that this study will be a good reference related to showing the relationship between soil invertebrates, fungi and soil biogeochemical cycles.
