Morphological Variability of Some Widespread and Rare Species of the Genus Navicula (Bacillariophyta)

Key Points

The study aims to analyze the morphological variability of several species of the genus Navicula.
Utilized scanning electron microscopy for detailed examination
Examined diatom algae from the Kilmez River
Quantified valve width and striae in 10 μm
Reviewed literature data for comparative analysis
Identified greater variability in quantitative characteristics of the species studied
Found significant differences in valve width, striae, and lineolae among species
Highlighted the importance of variability in algological research

Abstract

This scanning electron microscopy study was conducted to examine the morphological characteristics of a number of representatives of diatom algae of the genus Navicula (N. amphiceropsis, N. capitatoradiata, N. gregaria) from the phytobenthos of the Kilmez River. Some of the quantitative characteristics studied (valve width, number of striae and lineolae in 10 μm) and the analysis of literature data showed their greater variability, what needs to be considered when conducting algological research.
