摘要

2017年，分析了波兰上西里西亚四条河流中硅藻群落的组成。所研究的硅藻组合反映了采矿活动引起的人为盐碱化。以盐度最高为特征的河流（Bolina和Mleczna）中的组合显示出相对较低的分类学丰富度。硅藻群落以微咸水或海水的典型物种为主。人为影响最小或较弱的河流（Centuria和Mitrega）分别支持具有细颗粒基质的中海拔硅质或钙质溪流的分类丰富的硅藻组合。发现了一个新物种，Planothidium nanum sp.nov.的存在。新物种表现出一系列独特的形态特征，包括体型小；它的椭圆形轮廓以及胸骨瓣（窦）上间隔很宽的中央条纹和中缝瓣上间隔很广的中央条纹使它能够与其他类似的Planothidium分离。

Mining salinisation of rivers: its impact on diatom (Bacillariophyta) assemblages

The composition of the diatom assemblages was analysed in four rivers of Upper Silesia, Poland in 2017. The diatom assemblages studied were found to reflect anthropogenic salinization caused by mining activities. The assemblages in those rivers characterised by the highest salinity (Bolina and Mleczna) showed a relatively low taxonomic richness. The diatom assemblages were dominated by species typical of brackish or marine waters. The rivers with a minimal or weak anthropogenic impact (Centuria and Mitrega) supported taxonomically richer diatom assemblages typical of mid-altitude siliceous or calcareous streams (respectively), that have a fine particulate substratum. The presence of a new species, Planothidium nanum sp. nov., was revealed. The new species shows a unique set of morphological characters, including small size; its elliptical outline as well as very widely-spaced central striae on the sternum valve (sinus) and widely-spaced central striae on the raphe valve allow to separate it from other similar Planothidium.

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.
