Micrasterias thomasiana var. notata

The variety notata is very more common than the type variety. This optical transversal section of the desmid cell shows the outline, the surface texture of the chloroplast with many pyrenoids and the nucleus at the center of the cell. This picture was built up using appr. 20 high resolution DIC frames with manual stacking technique. The scale bar indicates 50 µm.
 
Sample from sphagnum pond situated in the northern alpine region of Austria near Salzburg. Images were taken using Zeiss Universal with Olympus C7070 CCD camera.

Die Varietät notata ist erstaunlicherweise viel häufiger als die Typusvarietät Micrasterias thomasiana. Der optische Querschnitt zeigt den Umriss und die Oberflächenstruktur der Chloroplasten mit vielen Pyrenoiden und den Kern in der Zellmitte. Tiefenschärfe durch Multiebenenabbildung aus 20 Bildebenen, manuell gestapelt. Der Messbalken markiert eine Länge von 50 µm.

Probe aus einem Moor in den nördlichen Kalkalpen von Österreich in der Nähe von Salzburg. Mikrotechnik: Zeiss Universal, Kamera: Olympus C7070.
