摘要

原生生物会影响土壤微生物组的组成和功能，从而有可能促进废弃物分解和植物生长。然而，不同的原生生物物种（单独或组合）在调节微生物介导的垃圾分解过程中的作用，以及这些相互作用是否会对植物生长产生反馈作用，目前仍是未知数。通过对三种原生动物物种组合与细菌和真菌群落进行全因子设计，我们发现只有一种原生动物物种能使垃圾分解量减少 19%，其他物种和组合均不影响垃圾分解。尽管植物生长与垃圾分解之间存在正相关，但我们并没有观察到原生动物诱导的植物生长变化。总之，我们的研究结果突出表明，原生动物以物种特有的方式影响着垃圾的分解，包括减少垃圾的分解。

Species-specific impact of protists in controlling litter decomposition

Protists affect soil microbiome composition and functioning, potentially increasing litter decomposition and plant growth. Yet, the role of different protist species, individually or in combinations, in regulating microbial-mediated litter decomposition remains unknown, as well as if these interactions feedback to plant growth. Using a full-factorial design of three protist species combinations with bacterial and fungal communities, we found that only one protist species reduced litter decomposition by 19%, with other species and combinations not affecting litter decomposition. Despite a positive correlation between plant growth and litter decomposition, we did not observe protist-induced changes in plant growth. Overall, our results highlight that protists affect litter decomposition in a species-specific manner, including reducing litter decomposition.
