Abstract

Microeukaryotic plankton communities are keystone components for keeping aquatic primary productivity. Currently, variations in microeukaryotic plankton diversity have often been explained by local ecological factors but not by evolutionary constraints. We used amplicon sequencing of 100 water samples across five years to investigate the ecological preferences of the microeukaryotic plankton community in a subtropical riverine ecosystem. We found that microeukaryotic plankton diversity was less associated with bacterial abundance (16S rRNA gene copy number) than bacterial diversity. Further, environmental effects exhibited a larger influence on microeukaryotic plankton community composition than bacterial community composition, especially at fine taxonomic levels. The evolutionary constraints of microeukaryotic plankton community increased with decreasing taxonomic resolution (from 97% to 91% similarity levels), but not significant change from 85% to 70% similarity levels. However, compared with the bacterial community, the evolutionary constraints were shown to be more affected by environmental variables. This study illustrated possible controlling environmental and bacterial drivers of microeukaryotic diversity and community assembly in a subtropical river, thereby indirectly reflecting on the quality status of the water environment by providing new clues on the microeukaryotic community assembly.

亚热带河流中微真核浮游生物的进化制约因素可通过环境和细菌的不同分类分辨率来解释。
微真核细胞浮游生物群落是保持水生初级生产力的关键组成部分。目前,微真核细胞浮游生物多样性的变化通常由当地生态因素而非进化限制因素所解释。我们利用扩增子测序技术,对一个亚热带河流生态系统中的微真核细胞浮游生物群落的生态偏好进行了研究。我们发现,与细菌多样性相比,微真核细胞浮游生物多样性与细菌丰度(16S rRNA 基因拷贝数)的相关性较低。此外,环境效应对微真核浮游生物群落组成的影响大于细菌群落组成,尤其是在细分类水平上。微真核浮游生物群落的进化限制随着分类学分辨率的降低而增加(从 97% 到 91% 的相似性水平),但从 85% 到 70% 的相似性水平变化不大。然而,与细菌群落相比,进化约束受环境变量的影响更大。这项研究说明了亚热带河流中微真核生物多样性和群落组合的可能控制性环境和细菌驱动因素,从而通过提供微真核生物群落组合的新线索间接反映了水环境的质量状况。
