The scattered in the literature data on the occurrence and distribution of the Paramecium aurelia spp. complex in Europe are compiled in the present communication. The number of investigated clones and habitats as well as the ratio value (r.v.), i.e. the number of habitats for a defined species to the total number of habitats of the area were taken into consideration when the frequency of species occurrence was estimated. Among 8 species present in Europe, P. novaurelia is a dominant species (r.v. 0.45), P. biaurelia is a frequent one (r.v. 0.37), and P. primaurelia less frequent (r.v. 0.27). Other species are rare, i.e. P. tredecaurelia, P. pentaurelia, P. sexaurelia, P. triaurelia, and P. tetraurelia.

13 habitats (17 sampling places) in the Slovak Tatra National Park were investigated with regard to the Paramecium aurelia species complex and other zooplankton. No species of the aurelia complex were found, only paramecium bursaria and P. caudatum were recorded at some sampling places. In the studied water bodies acidification of water was noted. This caused impoverishment of their zooplankton composition including ciliates.

The genetic differentiation of strains within Paramecium triaurelia was studied by intra- and inter-strain crosses of the Spanish strains from Castile and Andalusia and the standard one (strain 324 from Florida, USA).The clones of both generations F1 obtained by conjugation and F2 by autogamy, in intra- and inter-strain crosses showed a high survival rate.It was found that strains coming from remote regions were not genetically differentiated within P.triaurelia, which confirms the moderate inbreeding type of the breeding system of the studied species.

The clones of the P. aurelia spp. originated from Lake Beysehir from Turkey (Anatolian Upland) were identified as Paramecium novarelia. It is the first recorded habitat of that species outside Europe. Probably the species, common in Europe, has a wider range than had been supposed and its other habitats might be found in Asia.

The results of intra- and inter-strain crosses carried out in and between the strains from Spain, Poland, and Turkey, and the standard one (510, Scotland) of Paramecium novaurelia are presented. The inter-strain crosses were also made between the studied strains. The results showed that strains coming from the distant regions of Europe (i.e. from Spain, Poland, Scotland) and from Asiatic part of Turkey were not genetically differentiated within P. novaurelia. In the studied species of the P. aurelia complex there exists a type of breeding system which can be called moderate inbreeding.

On the studied territory the presence of Paramecium primaurelia (in two habitats),P. triaurelia (in 4 habitats), and P. novaurelia (in 8 habitats) was recorded. In three habitats last two species appeared together. The results confirm the appearance of P. novaurelia in Europe in many investigated places, and extend the range of P. triaurelia in Europe to the east.

The results of intra- and inter-strain crosses carried out between the Ukrainian strains and the standard one are presented. Also inter-strain cross was made between strains from distant regions of Europe, i.e. from Spain and Ukraine. The results showed that strains coming from different localities in Ukraine as well as from the distant regions of Europe, i.e. Spain and Ukraine, or even originating from Europe and the USA, were not genetically differentiated within P. triaurelia. The studied strains can interbreed in spite of their geographical isolation. The results indicate that in the studied species of the P. aurelia complex there exists a type of breeding system which can be called moderate inbreeding.

In the samples collected on the territory of the recently studied region of the Eastern Carpathians, i.e. in the Gorgany Mts, the presence of P. novaurelia was recorded in the samples collected from the bog situated on the Jab?onica Pass at an altitude of 1100 m. This is the first record of the presence of P. novaurelia in the Gorgany Mts.

In the samples collected from the water bodies situated on the territory of the recently studied regions of the Eastern Carpathians in Ukraine no Paramecia belonging to the Paramecium aurelia species complex were found.Only the presence of the related taxonomic species Paramecium caudatum and Paramecium multimicronucleatum was recorded.The studied water bodies were oligotrophic and the composition of planktonic organisms in them was rather poor.The crucial factor which affecting the plankton composition may be the water chemistry, determined by the subsrtatum, and considerably dependent also on the season of sampling.

A high percentage of surviving clones of F1 and F2 generations was observed in intra- and inter-strain crosses of the studied Romanian strains. A similar survival was also found in the inter-strain crosses of the Romanian strains with the standard (324) strain of the species, and in the crosses of both Romanian strains with the strains from Spain. Hybrids of the inter-strain crosses did not show any cytological disorders in the nuclear apparatus. The results prove the absence of genetic barriers between the studied strains, coming from Romania and Spain, and the American one.

The results of crosses carried out between the strains originating from regions of Europe distant from each other, i.e. from Spain and Hungary as well as between them and the standard strain of P. pentaurelia from Pennsylvania, USA are presented. It seems that the studied strains are not genetically differentiated within P. pentaurelia and that the species is characterized by moderate inbreeding.

In the present paper the results are given of the studies, i.e. intra- and inter-strain crosses carried out between the Polish and the Czech strains (from the Sudeten Mts) and the standard one. Also inter-strain crosses were made between strains from remote regions of Europe, i.e. from Poland and Romania, and from Poland and Spain. The results showed that strains coming from different habitats of the Sudeten Mts as well as from the remote regions of Europe, i.e. Poland, Spain, and Romania, or even originating from Europe and the USA, were not genetically differentiated within P. triaurelia. The studied strains can interbreed in spite of their geographical isolation. The results indicate that in the studied species of the P. aurelia complex there exists a type of breeding system which can be called moderate inbreeding.

Inter- and intra-strain crosses were made in Paramecium biaurelia of the P. aurelia species complex for studying the relation of strains within the species. Altogether ten strains originating from Scotland, Spain, Romania, Czech Republic, Ukraine, Italy, Germany, Russia, and Poland (two strains) were studied. A high percentage of surviving clones in both generations, F1 (obtained by conjugation) and F2 (obtained by autogamy), was observed in strain crosses, indicating a strong relation between the strains, and absence of genetic barriers between them in P. biaurelia.

As a result of the present study Paramecium biaurelia was found in the ponds of the Botanical Garden in Krakow. It was the only species from the aurelia complex present in the ponds. The finding confirms previous observations (KOMALA 1997, 1998 a,b) indicating that Paramecium biaurelia is a species which invades marginal habitats more easily than do the other species of the complex.
