摘要

摘要/ ABSTRACT摘要:synnedropsis abuflosensis sp. 11 .是在亚热带咸淡水栖息地记录的第三种，与极地分布相反。本种与本属其他种的区别在于，在瓣的两端的顶端狭缝区有不同数量的狭缝(即，末端4个有边缘狭缝，末端5个没有边缘狭缝)，一个顶端导向的边缘狭缝和3-4个无孔的环形带。它的栖息地与所有已知的Synedropsis Hasle, Medlin和Syvertsen物种不同，因为它要么是底栖的，要么是附生的，而不是浮游的或与海冰有关的。该新物种在电导率为7.1µS cm-1(盐度为3.3 psu)、温度为33°C的水中被发现。根据光镜和扫描电镜观察描述了新种的形态特征。本文对稻穗草(S. abuflosensis sp. 11 .)与形态相似的种进行了比较。

Synedropsis abuflosensis sp. nov., a New Araphid Diatom (Bacillariophyceae) from the Shatt Al-Arab River, Southern Iraq

ABSTRACT Synedropsis abuflosensis sp. nov. is the third species of the genus recorded from a sub-tropical brackish water habitat as opposed to a polar distribution. This species is differentiated from others in the genus by having a different number of slits in the apical slit field at opposite ends of the valve (i.e., 4 at the end possessing a rimoportula versus 5 at the end lacking a rimoportula), an apically oriented rimoportula and 3-4 non-porous cingular bands. Its habitat is different than that of all known Synedropsis Hasle, Medlin & Syvertsen species as it is either benthic or epiphytic in algal mats rather than planktonic or associated with sea ice. The new species was found in waters with a conductivity of 7.1 µS cm-1 (salinity 3.3 psu) and a temperature of 33 °C. Morphological characters of the new species are described based on light and scanning electron microscopy observations. A comparison of S. abuflosensis sp. nov. with morphologically similar species is provided.

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.
