Abstract

ABSTRACT In the present study, a new species, Nitzschia haloserbica Vidaković, Ector, C.E.Wetzel & Krizmanić, sp. nov., is described from alkaline saline ponds and channels from Vojvodina Province (Serbia). In 2019 the new species was found in four saline ponds: Bela Bara, Čoka Kopovo, Velika Rusanda and Slatina. The same species was recorded four years ago in saline lakes in Hungary, but the authors listed it as Nitzschia sp. 2. The sigmoid valve outline of the new Nitzschia Hassall species is similar to N. austriaca Hust. but differs in striae density and fibulae distribution. In N. haloserbica sp. nov. the transapical striae are so dense that they are not visible in light microscopy. Both species have fibulae that are quite regularly distributed along the raphe canal, but in N. austriaca the central two fibulae are more widely spaced, reflecting the presence of central raphe endings, which are absent in N. haloserbica sp. nov. At the type locality (Bela Bara) both species were found with relative abundances of 94.93 % for N. haloserbica sp. nov. and 1.21 % for N. austriaca (of the 400 valves counting per slide). The valve morphology, ultrastructure and autecology of the new species are discussed and compared with morphologically similar taxa.

标题塞尔维亚盐沼一新种(硅藻科，硅藻门)

摘要在塞尔维亚伏伊伏丁那省(Vojvodina)的碱水池塘和河道中发现了一新种Nitzschia haloserbica vidakoviki, Ector, C.E.Wetzel & krizmaniki, sp. nov.。2019年，在四个盐沼中发现了新物种:贝拉巴拉、Čoka Kopovo、Velika Rusanda和斯拉蒂纳。同样的物种四年前在匈牙利的盐湖中被记录，但作者将其列为Nitzschia sp. 2。Nitzschia Hassall新种的s形瓣轮廓与N. austaca Hust相似。但纹密度和腓骨分布不同。在N. haloserbica sp. 11 .中，跨根尖条纹非常密集，在光学显微镜下看不见。这两个物种都有沿中缝沟道规律分布的小管，但在奥地利白麻中，中间的两个小管间隔更宽，反映了中缝末端的存在，而在11月黑麻中则没有。在模式区域(贝拉贝拉)，这两个物种的相对丰度分别为94.93%和1.21%(每片400个瓣)。讨论了新种的瓣形态、超微结构和解剖学特征，并与形态相似的分类群进行了比较。

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.
