    Opis:
    The studies included 2 water bodies in Cracow (Kraków), 6 water bodies in the commune of Zabierzów (Cracow County) and 4 in the commune of Niepołomice (Wieliczka County). The studies were carried out in June 2018 and May 2019. The ways on management of the water bodies were compared. Problems related to revitalization were identified. One of these problems is the preservation of biodiversity. In some cases revitalization reduces biodiversity. This can happen due to the liquidation or limitation of the reed bed zone. Such a situation was observed in the water bodied of Zelków and Karniowice (com. Zabierzów). Both have ornamental functions now. Removal of most of reed does not disturb mallards (Anas platyrhynchos), but makes it impossible to nest for other birds such as moorhen (Galinula chloropus). Moorhens were observed in two former fish ponds in Staniątki (com. Niepołomice) and in the pond of the Kaczeńcowa street. In one of them revitalization caused the diminishing of the water area, but did not change the character of the water body. Bird species were recorded at water bodies.

    Opis:
    The purpose of this study was to assess the contemporary conditions of the lichen biota in the eastern part of the “Paprocie Serpentynitowe w Masywie Ślęży” ecological area in the Sudetes Foothills. The studies were carried out at three localities selected from 10 sites that were designed to protect the Asplenium fern genus. A total of 47 lichen species were found in the three localities. For each of the recorded species, the state of preservation in the Ślęża Massif area was assessed according to three factors: frequency at all three localities, general viability of the thalli, and stability in occurrence on the habitat. Stability was defined based on contemporary and historical data. From the analysis, most of the species (17) were classified as taxa with “moderate preservation status” in the study area. However, the preservation status of the 18 newly recorded taxa was defined as “insufficient data” due to the lack of previous records. Other species received a “very good preservation status” (three taxa) and “good preservation status” (nine taxa). The analyses allowed us to document the current number of taxa, determine their health condition, and indicate trends in the transformation within the lichen biota of the serpentinite rocks in the study area. Moreover, some actions were proposed to actively protect the valuable lichens in the ecological area of “Paprocie Serpentynitowe w Masywie Ślęży.”

    Opis:
    Genetic variability of three sympatric crucian carp (Carassius carassius) populations from NW Poland was studied within a research project aimed at assessing the utility of those populations for stocking in inland waters. DNA samples were collected from 65 individuals. Restriction analysis was performed using 4 enzymes (HaeIII, HinfI, FspBI, TasI) of known restriction sites. The restriction profiles obtained were classi fied as belonging to a single haplotype (H-1). Selected DNA products were sequenced; the subsequent comparison made it possible to detect the presence of substitutions in the genome fragment analysed.
