Diatom taxonomy and environmental drivers of biodiversity in the Taleghan River and reservoir in Central Alborz, Iran
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.
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.
