Abstract

In this work, we propose and describe a novel diatom species, Fistulifera alcalina sp. nov., isolated from Port Mayaca on Lake Okeechobee, Florida (USA). This new diatom species represents a distinct lineage within the genus Fistulifera, which includes F. iranensis (Hustedt) Lange-Bertalot, F. saprophila (Lange-Bertalot & Bonik) Lange-Bertalot, F. pelliculosa (Kützing) Lange-Bertalot, and F. solaris S. Mayama, M. Matsumoto, K. Nemoto & T. Tanaka. Morphometric and molecular phylogenetic analyses of the 18S rRNA and rbcL genes strongly support Fistulifera alcalina as a new species. Fistulifera alcalina sp. nov. is cultured in media with moderate salinity and high bicarbonate concentrations in contrast to the other species of Fistulifera which show ecological preferences for high salinity and eutrophic or oligotrophic waters. This is also the first record of Fistulifera in the southeastern United States (Florida, USA).

Fistulifera alcalina sp.nov.（Naviculales，Stauroneidaceae）一种产于美国佛罗里达州奥基乔比湖的新型嗜碱硅藻

在这项工作中，我们提出并描述了一种新的硅藻物种，Fistulifera alcalina sp. nov.，分离自美国佛罗里达州奥基乔比湖的玛雅卡港。这一新的硅藻物种代表了fisstulifera属中一个独特的谱系，其中包括F. iranensis (Hustedt) Lange-Bertalot, F. saprophila (Lange-Bertalot & Bonik) Lange-Bertalot, F. pelliculosa (k tzing) Lange-Bertalot和F. solaris S. Mayama, M. Matsumoto, K. Nemoto和T. Tanaka。18S rRNA和rbcL基因的形态测定和分子系统发育分析有力地支持了该属新种的存在。在中等盐度和高碳酸氢盐浓度的培养基中培养alcalina sp. 11 .与其他种类的fisstulifera相比，它们表现出对高盐度和富营养化或少营养化水域的生态偏好。这也是在美国东南部(美国佛罗里达州)首次记录到的fisstulifera。

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.
