Abstract

The taxonomic composition of the diatom flora of the Taleghan River and reservoir in Iran is described. The Taleghan River is one of the main tributaries of the Sepid Roud River, which is the second-longest river in Iran (∼ 670 km). Its headwaters are located in the Alborz Mountains in northwestern Iran and discharge into the Caspian Sea (North Iran). The current study was conducted from November 2017 to October 2018. A total of 167 taxa belonging to 49 genera and 27 families were identified. Nitzschia (28 spp.) Navicula (20 spp.), Cymbella (12 spp.), and Gomphonema (10 spp.) were the most abundant genera. The identified taxa can be classified as oligosaprobic to eutrophic and Canonical Correspondence Analysis (CCA) showed that temperature, NO3 2−, salinity, turbidity, EC, Si, and DO were the most significant environmental variables influencing diatom assemblages across seasons and sites in the river.

伊朗中部Alborz的Taleghan河和水库中硅藻分类和生物多样性的环境驱动因素

描述了伊朗塔勒甘河及其水库硅藻区系的分类组成。塔勒甘河是伊朗第二大河(约670公里)赛皮德河的主要支流之一。它的源头位于伊朗西北部的阿尔博尔斯山脉，流入里海(伊朗北部)。目前的研究是在2017年11月至2018年10月进行的。共鉴定出27科49属167个分类群。尼氏属(28种)、Navicula属(20种)、Cymbella属(12种)和Gomphonema属(10种)数量最多。典型对应分析(CCA)表明，温度、no32 -、盐度、浊度、EC、Si和DO是影响硅藻群落在不同季节和地点分布的最显著环境变量。

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.
