摘要

尾矿的原生演替是尾矿植被形成的先决条件。包括细菌、真菌和原生生物在内的微生物在这一过程中起着重要的推动作用,是改善营养状况的动力。与细菌和真菌相比,原生生物种群在尾矿中的作用很少被研究,特别是那些与初级演替有关的尾矿生物。原生生物是真菌和细菌的主要消费者,它们的捕食行为促进了固定在微生物生物量中的营养物质的释放,以及营养物质的吸收和周转,影响了更广泛的生态系统的功能。本研究以3个演替阶段(原始尾砂、生物结壳和芒草草地)的3种不同类型的尾矿为研究对象,对原始演替过程中原生生物群落的多样性、结构和功能进行了研究。一些被归类为消费者的成员主导了尾矿中微生物群落的网络,特别是在原始裸地尾矿中。绿藻门和海藻门的重点光养菌在生物结壳和草地根际的相对丰度最高。此外,原生生物与细菌类群的共生现象表明,原生生物光养生物的比例在原生演替过程中逐渐增加。此外,原生生物代谢势的宏基因组分析表明,在尾矿初次演替过程中,许多与光合作用相关的功能基因的丰度增加。综上所述,这些结果表明,尾矿的初次演替驱动了原生生物群落的变化,反过来,原生生物光养生物促进了尾矿的初次演替。本研究初步揭示了尾矿生态演替过程中原生生物群落的生物多样性、结构和功能的变化。

Primary Succession Changes the Composition and Functioning of the Protist Community on Mine Tailings, Especially Phototrophic Protists

Primary succession in mine tailings is a prerequisite for tailing vegetation. Microorganisms, including bacteria, fungi, and protists, play an important role in this process in the driving force for improving the nutritional status. Compared to bacteria and fungi, protist populations have rarely been investigated regarding their role in mine tailings, especially for those inhabiting tailings associated with primary succession. Protists are the primary consumers of fungi and bacteria, and their predatory actions promote the release of nutrients immobilized in the microbial biomass, as well as the uptake and turnover of nutrients, affecting the functions of the wider ecosystems. In this study, three different types of mine tailings associated with three successional stages (original tailings, biological crusts, and Miscanthus sinensis grasslands) were selected to characterize the protistan community diversity, structure, and function during primary succession. Some members classified as consumers dominated the network of microbial communities in the tailings, especially in the original bare land tailings. The keystone phototrophs of Chlorophyceae and Trebouxiophyceae showed the highest relative abundance in the biological crusts and grassland rhizosphere, respectively. In addition, the co-occurrences between protist and bacterial taxa demonstrated that the proportion of protistan phototrophs gradually increased during primary succession. Further, the metagenomic analysis of protistan metabolic potential showed that abundances of many functional genes associated with photosynthesis increased during the primary succession of tailings. Overall, these results suggest that the primary succession of mine tailings drives the changes observed in the protistan community, and in turn, the protistan phototrophs facilitate the primary succession of tailings. This research offers an initial insight into the changes in biodiversity, structure, and function of the protistan community during ecological succession on tailings.
