Abstract

Ciliates are core components of the structure of and function of aquatic microbial food webs. They play an essential role in the energy flow and material circulation within aquatic ecosystems. However, studies on the taxonomy and biodiversity of freshwater ciliates, especially those in wetlands in China are limited. To address this issue, a project to investigate the freshwater ciliates of the Lake Weishan Wetland, Shandong Province, commenced in 2019. Here, we summarize our findings to date on the diversity of ciliates. A total of 187 ciliate species have been found, 94 of which are identified to species-level, 87 to genus-level, and six to family-level. These species show a high morphological diversity and represent five classes, i.e., Heterotrichea, Litostomatea, Prostomatea, Oligohymenophorea, and Spirotrichea. The largest number of species documented are oligohymenophoreans. A comprehensive database of these ciliates, including morphological data, gene sequences, microscope slide specimens and a DNA bank, has been established. In the present study, we provide an annotated checklist of retrieved ciliates as well as information on the sequences of published species. Most of these species are recorded in China for the first time and more than 20% are tentatively identified as new to science. Additionally, an investigation of environmental DNA revealed that the ciliate species diversity in Lake Weishan Wetland is higher than previously supposed.

微山湖湿地淡水纤毛虫(原生纤毛虫,纤毛虫)生物多样性研究进展。
纤毛虫是水生微生物食物网结构和功能的核心组成部分。它们在水生生态系统的能量流动和物质循环中起着至关重要的作用。然而,国内对淡水纤毛虫的分类学和生物多样性,特别是湿地纤毛虫的研究还很有限。为解决这一问题,2019年启动了山东省微山湖湿地淡水纤毛虫调查项目。在这里,我们总结了迄今为止关于纤毛虫多样性的发现。共发现纤毛虫187种,其中种级鉴定94种,属级鉴定87种,科级鉴定6种。这些物种具有高度的形态多样性,可分为5个纲,即异口虫纲、立口虫纲、原口虫纲、寡膜虫纲和螺旋体虫纲。记录的种类最多的是少膜蜂。建立了包括形态数据、基因序列、显微镜载玻片标本和DNA库在内的完整的纤毛虫数据库。在本研究中,我们提供了检索到的纤毛虫的注释清单以及已发表物种的序列信息。这些物种大多数是首次在中国记录到的,超过20%被初步确定为科学上的新物种。此外,环境DNA调查显示,微山湖湿地的纤毛虫物种多样性高于之前的假设。补充信息:在线版本包含补充资料,提供地址为10.1007/s42995-022-00154-x。
