The Significance of Stone Moroko, Pseudorasbora Parva (Temminck and Schlegel), in the Small-Sized Fish Assemblages in the Littoral Zone of the Heated Lake Licheńskie
The aim of the study was to determine changes in the seasonal abundance of stone moroko, Pseudorasbora parva (Temminck and Schlegel), and to identify the role this alien species plays in the littoral zone of a heated lake. This study also aimed at defining the habitat preferences of this species and describing the relations between the relative abundance of stone moroko and the occurrence of submerged vegetation. A significant dependence was determined of the degree to which the lake bottom is covered with macrophytes and the occurrence of stone moroko. The fish caught belonged to 14 species and 2 families. Stone moroko preferred habitats that were abundantly overgrown with submerged vegetation and avoided areas devoid of macrophytes. Thus, as the bottom cover increased, so did the relative number of this fish. In light of habitat availability and its food preferences, the abundant occurrence of this species poses a serious threat to the endemic ichthyofauna.

Ciliates on the Macrophytes in Industrially Heated Lakes (Kujawy Lakeland, Poland)
The ciliate assemblage on the macrophytes was examined in 2005 during the vegetation period in the Konińskie Lakes which are heating by post-cooling waters from thermal electric plants. As a result of changed temperature regimen the alien thermophilic macrophyte Vallisneria spiralis is becoming increasingly common in the littoral zone. A total of 150 ciliate taxa belonging to 27 orders were found. Greater ciliate species diversity was found on architecturally complex, submerged forms such as Ceratophyllum demersum and Myriophyllum spicatum. By contrast the ciliate compositions on emergent macrophytes with simple architecture in their submerged parts, such as Typha, Sparganium, or Acorus, were less species rich. Despite the simple architecture of Vallisneria leaves, the ciliate diversity on them was high. The results show that replacement of native macrophytes by the alien form V. spiralis in heated lakes did not impoverish the ciliate diversity.
