After treatment of the paramecia with 0.0005% cartap solution a high mortality of the paramecia of 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.

In 1977 the Babia Gora National Park (the BPN) was included by UNESCO in the list of the international network of the Biosphere Reserves that comprise the world's protected ecosystems.The investigation, which is being carried out in the area of the BPN, aims at finding and recording species of the zooplankton as well as the Paramecium aurelia species complex occurring in the lakes of Mt Babia Gora. The investigation was carried out in Mokry Stawek, one of the largest lakes in the area. This is a preliminary report. It reveals a significant acidity of the lake and that so far none of the examined species of the Paramecium aurelia complex have been found. However, some predominant zooplanktonic organisms were registered.

The present investigations are a continuation of the previous studies on the zooplanktonic organisms in the waters of the Babia G?ra massif and its buffer zone (Komala 1996, 1997a,b, 1998a). In particular, the lakes situated on its southern slope were studied at present from the point of view of the occurrence of the Paramecium aurelia species complex and other zooplankton. So far none of the investigated species of the complex have been found, however, some dominant zooplankton was registered.

The study revealed an impoverishement of the zooplankton community in the investigated water bodies of the Szczawnica region. The results were compared with data obtained from 1977-1983 in this area.

The present investigation are a continuation of the previous studies on the zooplanktonic organisms in the waters of the enclave situated in the borderland of Sredni and Wyspowy Beskids (the Carpathians). In particular, the streams in the valley of the River Krzczonowka and the waters of the Krzczonowka itself were studied from the point of view of the occurrence of the Paramecium aurelia species complex and other zooplankton. Recently, the waters in the region have shown a significant acidity in comparison with pH values noted in the sixties. So far, none of the species of the aurelia complex have been found in the streams as well as in the river. However, some predominant zooplanktonic organisms were registered. Previously (Komala 1998d) P. biaurelia was found in the Bogdanowka stream which flows into Krzczonowka, the main river of the valley.

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 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.

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.

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.

The present work reports a recent preliminary analysis of the zooplanktonic organisms in selected water bodies of the village Zubrzyca Gorna in the Orawa valley. As far as the genus Paramecium is concerned, Paramecium caudatum was found. No species of the Paramecium aurelia complex were recorded although in previous years Paramecium biaurelia and P. novaurelia were found in the Orawa valley waters. It seems that the absence of species of the aurelia complex in a given water body may be caused by an increase in the water acidity.

The occurrence of animal communities in certain water bodies of the Babia region (the Upper Zawoja and its vicinity) was studied. Some problems of environmental pollution and impoverishment of the plankton organisms in the waters of the region are discussed.

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.

This preliminary report reveals a significant acidity of the lakes on the Babia Gora massif, and rather poor differentiation of the zooplanktonic organisms. So far none of the investigated species of the Paramecium aurelia complex have been found. However, some dominant zooplankton was registered in all six investigated lakes.

Some predominant zooplanktonic organisms were registered in several water bodies of Mt Babia Gora.

The investigations were carried out in the village Letownia situated at an altitude of 470-625 m in the picturesque enclave on the border of the Makowski and Wyspowy Beskids. The new habitat of Paramecium biaurelia was found in the River Letowka.
EN
In the water bodies in the region of the Orawa Valley (Carpathians) new habitats of Paramecium biaurelia and P. novaurelia were found. The species are the most common also in the other studied parts of the Carpathians as well as in the whole Poland.
EN
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.

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.

The aim of this study was to register the zooplanktonic organisms in water bodies in the Botanical Garden of the Jagiellonian University in Krak?w, 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.
