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.
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.
