Zooplankton in the artificial pond of the Botanical Garden of the Jagiellonian University in Kraków.

Paramecium caudatum and the predominant zooplanton organisms were registered in the studied pond of the Botanical Garden of the Jagiellonian University in Kraków. The finding of Stentor coeruleus indicates an improvement in the environmental conditions in Kraków, connected with the partial liquidation of the huge steelworks.

Zooplankton in the ponds with tropical plants in the greenhouses of the Botanical Garden of the Jagiellonian University in Kraków.

The presence of P. tetraurelia was found in the pond in "The Palm-House" greenhouse.

Paramecium aurelia species complex in the catchment area of the River Raba mountain course (the Carpathians).

In the water bodies of the Beskid Wyspowy Mts three species of the Paramecium aurelia complex have been found, i.e. P. biaurelia, P. tetraurelia and P. novaurelia. P. tetraurelia, which in Europe is a very rare species, was for the first time recorded in this region of the Carpathians.

Paramecium aurelia species complex in the River Raba (southern Poland).

This report reveals a significant acidity of the River Raba at all the investigated sampling points, and rather poor differentiation of the zooplanktonic organisms. At one sampling point the presence of Paramecium biaurelia was registered.

Notes on the zooplankton of a water body on the southern slope of Mt Babia Góra (the Carpathians).

The seepage of water on the Gubernasówka clearing in the forest (alt. about 850 m) was investigated from the point of view of the occurrence of the Paramecium aurelia species complex and other zooplanktonic organisms. Though, none of the species of the complex was found, another morphological species of the Paramecium genus, i.e. Paramecium caudatum was registered.

Further investigations on the zooplankton of water bodies in the Botanical Garden of the Jagiellonian University in Kraków.

The aim of this study was to register the zooplanktonic organisms in water bodies in the Botanical Garden of the Jagiellonian University in Kraków, especially from the point of view of the occurrence of species of the Paramecium aurelia complex. In one pond, artificially constructed, the presence of P. tetraurelia was revealed.

Zooplankton of some water bodies of the Zoological Garden in Kraków.

The aim of this study was to register the zooplanktonic organisms in water bodies in the Zoological Garden in Kraków, especially from a point of view of the occurrence of species of the Paramecium aurelia complex. Only P. caudatum was found in one habitat, in several sampling places. The species seems very resistant and can survive in poor or polluted habitats in which the P. aurelia ssp. are eliminated.

Paramecium aurelia species complex in a natural but newly reconstructed pond of the Botanical Garden of the Jagiellonian University in Kraków.

In a natural but newly reconstructed pond the presence of P. biaurelia was revealed. The previous studies conducted in 1992 did not reveal the occurrence of any species of the Paramecium aurelia complex here.

Notes on the use of invertebrates, especially ciliates, in studies on pollution and toxicity.

After treatment of the paramecia with 0.0005% cartap solution a high mortality of the paramecia in the postautogamic experimental group was observed. In the studied postautogamic experimental daily isolation line some defective paramecia were found. The abnormality was manifested by a defective separation of animals during binary fission resulting in the formation of chain forms.

Paramecium triaurelia and other species of the aurelia complex in the Kaczawskie Mts and Plateau (western Sudeten).

The present investigations revealed the occurrence of Paramecium triaurelia on the territory of the Kaczawskie Plateau, while its presence was confirmed in the Kaczawskie Mts. In Poland, the presence of this species was recorded only in the Western Sudeten, in spite of many years of investigation. As the result of the studies also the occurrence of P. biaurelia and P. novaurelia was recorded on the territory of the Kaczawskie Mts and the Kaczawskie Plateau.

Effects of atmospheric pollution on Paramecium sp. cells.

The toxicity level of heterocyclic compound fractions obtained from dust in Silesia for Paramecium primaurelia was studied. For the estimation of their toxicity a special scale elaborated for this material was used. It was found that the level of toxicity of investigated fractions differed, depending on the sampling place and season of the year.

Studies on the distribution of the Paramecium aurelia species complex of Poland.

Species of the Paramecium aurelia complex occurred in the studied regions of the Carpathians and the Sudetes Mts with varying frequency. P. novaurelia appeared most often, P. biaurelia occurred less frequently but was also very characteristic, both species prevailed over P. primaurelia. P. tetraurelia and P. triaurelia were very rare.

Toxicity of Fastac 10 EC, a pyrethroid insecticide, to Paramecium primaurelia and Tubifex sp.

The pyrethroide, Fastac 10 EC was tested on the paramecia and Tubifex sp. The results showed that both tests are valid for estimation of the toxicity of the pesticide. However, the Paramecium test is more sensitive when one is investigating the direct toxicity of the compound. The great validity of the Tubifex test lies in the possibility of tracing the teratogenic effects of the pesticides.

Species of the Paramecium aurelia complex in the middle Sudeten of Czecho-Slovakia.

On the investigated territory three species of the complex were identified, namely Paramecium biaurelia, P. triaurelia, and P. novaurelia. P. novaurelia dominated over the other species with regard to the number of clones established from nature as well as to habitats.
