Abstract

Abstract During an investigation on the diatom communities of volcanic lakes of Northeastern China a new species belonging to the “Cyclotella comta species complex” was observed. This taxon forms relatively large populations in the phytoplankton of Lake Tuofengling Tianchi, a 33m-deep, oligotrophic, crater lake located in Inner Mongolia. In this paper, the valve morphology and ultrastructure of this taxon is described using light and scanning electron microscopy and a new name, Lindavia khinganensis sp. nov., is proposed. A discriminant analysis based on morphological LM and SEM data confirmed that L. khinganensis is distinct from other Lindavia species with a similar morphology such as L. comta (Ehrenberg) Nakov et al., L. radiosa (Grunow) De Toni & Forti, L. balatonis (Pantocsek) Nakov et al., L. praetermissa (Lund) Nakov et al. and L. tenuistriata (Hustedt) Nakov et al. In addition, the seasonal and interannual distribution of L. khinganensis was investigated using sediment trap samples collected over a two-year period. Limnological data from Lake Tuofengling, including water chemistry and temperature recording from a thermistor chain provided complementary information about the ecology of this new species. This species was not found in any other lakes from Northeastern China that we investigated.

属于Cyclotella comta (Ehrenberg) k tzing复合体的一种新中心硅藻的形态和生态学:大兴安岭Lindavia khinganensis sp. nov.

摘要在对东北火山湖硅藻群落的调查中，发现了一种属于“Cyclotella comta种群”的新种。该分类群在内蒙古托峰岭天池湖浮游植物中形成了相对较大的种群。托峰岭天池湖是一个深33米的贫营养火山口湖。本文利用光镜和扫描电镜对该分类群的阀瓣形态和超微结构进行了描述，并提出了一个新名称linddavia khinganensis sp. nov.。基于形态学LM和SEM数据的判别分析证实，L. khinganensis不同于L. comta (Ehrenberg) Nakov等人、L. radiosa (Grunow) De Toni & Forti、L. balatonis (Pantocsek) Nakov等人、L. praetermissa (Lund) Nakov等人以及L. tenuistriata (Hustedt) Nakov等人等形态相似的林达属植物。此外，利用沉积物诱捕器采集了2年的样品，研究了兴安草的季节和年际分布。沱峰岭湖的湖泊数据，包括水化学和热敏电阻链的温度记录，为该新种的生态学提供了补充信息。本种在我们调查的东北其他湖泊中均未发现。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
