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.

Fragments of LSU rDNA and COI mtDNA genes were sequenced in Paramecium tetraurelia strains originating from different continents, i.e. from Australia (Sydney), Europe (Spain, Poland), Asia (Israel, India, Japan) and North America (Indiana) in order to investigate intra-specific polymorphism in this species. Phylogenetic trees (based on analyses using the NJ, MP and BI methods) revealed that P. tetraurelia strains from Australia, Europe, North America and Asia (Israel, Japan) belong to one group divided into two main clusters, while a strain from India is separate and belongs to a different group. The Indian strain groups together with strains representing different species of the P. aurelia complex: P. septaurelia, P. octaurelia, and P. dodecaurelia. Polymorphism within P. tetraurelia was confirmed, however, it seems that the applied markers did not explain the ways of divergence of strains within species (Indian strain and others), and also did not show correlations between geographic origin of strains and their genetic diversity. Some species of the P. aurelia complex seem closely related.

The presence of Paramecium sexaurelia from the Paramecium aurelia complex was recorded for the first time in China (Beijing). RAPD fingerprints (band patterns) of P. sexaurelia strains, the new strain from China and others from Asia, as well as from Europe and Puerto Rico, showed polymorphism within the species as several groups of genotypes characterized by different band patterns.

The first stand of Paramecium octaurelia in Europe (Germany) is described and interesting intra-specific polymorphism is compared within the species using strains originating from different continents (Europe, N. America and Asia). Sequenced fragments of 5. LSU rDNA and COI mtDNA revealed that the studied strains form two groups, one with strains from Germany and USA, and a second group from Israel.

The presence of P. biaurelia and P. triaurelia was recorded in one habitat, i.e. the Prutec stream, in the village Mykulychyn, the Gorgany Mts. Especially interesting seems the finding of a new habitat of P. triaurelia in Ukraine, and the first time in the Carpathians. It extends its range in Europe to the east.

The investigations were carried out in the borderland of the ?redni (Makowski) and Wyspowy Beskids (the Carpathians). In the River Bogdan?wka flowing out from the range of the Koskowe G?ry Mts (the Carpathians) Paramecium biaurelia was found. The results of the present work together with the previous data (KOMALA 1997, 1998) indicate that Paramecium biaurelia is more common in the investigated Carpathian region than other species of the aurelia complex. The results also indicate that this species is much more adaptive for acidic waters. Perhaps this ability makes the species capable of invading the marginal ecological niches more easily than is the case with other species of the group.

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 investigations were carried out in the region of Rabka, a well-known health resort, situated in a valley between the ranges of the Wyspowy Beskid and Gorce Mts (The Carpathians), on the River Raba. The Poniczanka stream which is a tributary of the River Raba has recently undergone investigation. This is a stream in which the presence of a very rare species of the P. aurelia complex, i.e. Paramecium tetraurelia, was found in 1961 (DUBIS, unpublished data). The present study revealed a significant acidification of the stream and the absence of the Paramecium tetraurelia. Among the species of the genus Paramecium only Paramecium caudatum was found, this morphological species, composed of several genetic ones, seems to be less sensitive to acid waters.

The investigations were carried out in a valley on the border of the Wyspowy and Sredni (Makowski) Beskids (the Carpathians). Paramecium biaurelia was found in several streams flowing into the main river. Paramecium novaurelia was found in one habitat only. The obtained results indicate that P. biaurelia is far more typical of the examined region - than other species of the Paramecium aurelia complex occurring in the Carpathian chain. They also indicate that P. biaurelia is a pioneering species of the complex.

Genetic distances among strains of P. sexaurelia were compared by sequencing the mitochondrial cytochrome b gene. The relationships of P. sexaurelia with representative strains of other species of the P. aurelia complex and related species, i.e. P. schewiakoffi, P. jenningsi and P. multimicronucleatum were evaluated. All investigated P. sexaurelia and P. dodecaurelia strains grouped together with high support. This P. sexaurelia/P. dodecaurelia cluster was furthermore composed of three distinct, strongly supported subgroups. Two of these groups contained both P. sexaurelia and P. dodecaurelia strains, suggesting that these species are not monophyletic. The third branch was composed of strains from Sevilla, Spain and was deeply separated (12-14 % p-distance) from the other P. sexaurelia/P. dodecaurelia clades. This illustrates the urgent need for further work and more intense sampling of these .rare. species, in order to understand the status and the relationships of P. sexaurelia and P. dodecaurelia within the P. aurelia species complex. We recommend that general investigations on the speciation process be conducted within and between species of the P. aurelia complex due to the high genetic variation combined with observations that for some of the species possible cryptic speciation may have occurred. This is emphasized by data showing that for some species within this complex, species status may be less static and more dynamic than originally thought.

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.

The presence of Paramecium decaurelia from the Paramecium aurelia species complex was demonstrated in Yaroslavl, Russia, (European part, northwestern Russia) and in the Altai Mts (Asiatic part of Russia, western Siberia). RAPD-PCR fingerprints of the newly identified strains of P. decaurelia, rare throughout the world, were compared to those characteristic for the other known strains of the species. P. decaurelia strains show some polymorphism within species, strains from Russia have 60% similarity of band patterns, and strains from USA and Japan about 70% similarity of band patterns.
