摘要

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。

Fistulifera alcalina sp. nov. (Naviculales, Stauroneidaceae) a new alkaliphilic diatom species from Lake Okeechobee, Florida (USA)

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).

期刊介绍： Diatom Research is the journal of the International Society for Diatom Research. The journal is published quarterly, in March, June, September and December, and welcomes manuscripts on any aspect of diatom biology. In addition to full-length papers, short notes and reviews of recent literature are published which need not contain all the sections required for full-length papers; we see these as being necessary to record information which is of interest but which cannot be followed up in detail. Discursive “Opinion” papers are encouraged which would not necessarily follow the normal lay-out. If extremely long papers are to be offered, the author(s) should contact the editors first to discuss any problems. Book reviews, obituaries and meeting reports can be published. All papers will be subject to critical review by the editors and referees, as appropriate to their content. Papers will be accepted in English only.
