Figure 3B: Relative abundance of tychoplanktonic and non-planktonic (acidophilous) diatom taxa - Lama Lake
POI!!! (NE Norilsk, W Siberia),
C. comensis and C. gordonensis) characterized DAZ-7, In DAZ-8, C. kuetzingiana var.
radiosa and C. comensis contributed 20 % each to the diatom assemblage, Strongly fluctuating
proportions of taxa in the planktonic group marked DAZ-9, terminating with a maximum
frequency of Fragilaria tenera (13 %),
