Most of the volumes of the series "Süßwasserflora von Mitteleuropa" are written in German language, the volumes 2/1 - 2/4 dealing with the Bacillariophyceae (diatoms) as well. They enable the user to identify all diatom-species and provide him with the taxonomic and ecological information. Since the number of the known diatoms-taxa has increased considerably it is extremely important to distinguish the different species. This was until now restricted to the limnologists, biologists and geographers capable of understanding the German language. This additional volume 2/5 presents all the dichoto Süßwasserflora von Mitteleuropa (2/5): Bacillariophyceae - Kurt Krammer, Horst Lange-Bertalot od authora Kurt Krammer, Horst Lange-Bertalot a nakladatelství za skvělé ceny na e-shopu Martinus. cz.
