Abstract
Diatoms are a widespread group of organisms with well-known ecological preferences. Knowledge of their diversity is of great importance for assessing the environmental status of different aquatic ecosystems. The present study was based on 55 different localities that included rivers, streams, channels, accumulations and salt marshes throughout Serbia. The results of this study expanded the diatom checklist by 80 taxa, including two new recorded genera (Fistulifera and Microfissurata) for Serbia. The data were obtained by combining light microscopy (LM) and scanning electron microscopy (SEM) that provided reliable identification, which is very important in diatom diversity studies.
Highlights
Species diversity is one of the main factors in assessing the environmental state of various aquatic ecosystems
A total of 80 diatom taxa belonging to 33 genera have been noted for the first time in Serbian diatom flora
On the territory of Serbia, c. 800 diatom taxa have been recorded to date
Summary
Species diversity is one of the main factors in assessing the environmental state of various aquatic ecosystems. It has an important role in ecosystem processes and functioning, food chains and ecosystem integrity [1]. The first diatom data in Serbia date from 1883 [16] It was only in the second half of the 20th century that extensive research into diatoms began [17,18,19,20,21], and in the last twenty years the number of new recorded diatom taxa for Serbian flora has increased [20,21,22,23,24]. The aim of this paper was to report new records of diatom taxa from different sites throughout Serbia in order to supplement the diatom checklist
