Clearance rate and food selectivity of bdelloid rotifers (Rotifera) in soil
 HLÁVKOVÁ, Daniela
This thesis is focused on food selectivity and clearance rate of bdelloid rotifers in soil. There is small information about these creatures and so the work was made with data known for planktonic species (monogononts and bdelloids) and bdelloid species live in the dendrothelms Habrotrocha thienemanni. The result is complex of factors affecting the clearance rate and food selectivity of planktonic species that could have a similar role in bdelloids.

Reaction of Soil Rotifers on Chemical Stress in Substrates of Spoil Heaps
 BIZOS, Jiří
Abundance and species composition of soil rotifer communities was investigated in two seasons and six sites on dumps in the Sokolov mining area (Czech Republic). Every site was split into three plots, which differed in toxicity for vegetation and chemical composition of spoil material. The ability of soil rotifers to live in environment of spoil materials and the effect of pollution were studied in field conditions. According to results, abundance and species composition did not correspond to chemical environmental characteristics. Species composition of rotifer communities was affected by environmental variables such as vegetation, more likely than direct effect of chemical composition of spoil material.
