尽管原生生物在土壤微生物组和全球生态过程中发挥着重要作用，但它们的大尺度生物地理格局和预测因子的特征却很少。研究原生生物的多样性和分布对于理解其生物地理格局以及系统发育、生态和功能尺度上的潜在驱动因素至关重要。在这里，我们探索了原生生物群落的大尺度模式，并将其与土壤功能联系起来，这些土壤样本来自9个大气候梯度的森林遗址的107个土壤样本。结果表明，森林土壤原生生物群落的生物地理基本符合温度多样性梯度（TDG）、代谢生态位理论（MNT）和距离衰减关系（DDR）。引人注目的是，作为环境选择和随机过程的结果，原生动物的优势门，尾虫门（消费者）和顶虫门（寄生虫）沿着气候梯度遵循了高度不同/对比的生物地理模式。cercozoa在寒冷干旱的土壤中相对丰富，而顶复合体在热带潮湿的土壤中茁壮成长。均一化扩散对尾虫的分布有较强的影响，而生态漂变控制着顶复虫的分布。此外，我们发现原生生物网络模块化解释了57.5%的土壤养分矿化变化，表明cercozoa和顶复合体在养分循环中的关键作用。总的来说，我们揭示了TDG、MNT和DDR对土壤原生生物群落的普遍适用性，并揭示了原生生物消费和寄生生物在气候梯度上的生物地理格局对比。我们的研究强调了原生生物群落对森林土壤养分矿化的重要贡献。
Despite their essential role in soil microbiome and the global ecological processes, large-scale biogeographical patterns and predictors of protists are poorly characterized. Investigating the diversity and distribution of protists is crucial for understanding their biogeographic patterns and underlying the drivers across phylogenetic, ecological, and functional scales. Here, we explored a wide-scale pattern of protistan communities, and linked it with soil functions, in 107 soil samples from nine forest sites along a large climatic gradient. Our results showed that the biogeography of protistan communities in forest soils generally fitted the temperature diversity gradients (TDG), metabolic niche theory (MNT) and distance-decay relationships (DDR). Strikingly, the dominant protistan phyla, Cercozoa (consumer) andApicomplexa(parasite), followed highly different/contrasting biogeographic patterns along the climatic gradient, as a result of environmental selection and stochastic processes.Cercozoawere relatively more abundant in cold arid soils whileApicomplexathrived in tropical wet sites. Homogenizing dispersal had a stronger effect on the distribution of theCercozoa, while ecological drift controlled the distribution of theApicomplexa. In addition, we found that protist network modularization explained 57.5% of the variation in soil nutrient mineralization, suggesting the critical roles ofCercozoaandApicomplexain nutrient cycling. Collectively, we showed the general applicability of TDG, MNT and DDR to the soil protistan communities and revealed contrasting biogeographic patterns of protistan consumer and parasite along climatic gradients. Our study highlights the crucial contribution of protistan communities to nutrient mineralization in forest soils.
