Two hundred species of vascular plants were identified in grasslands on the Popielno Peninsula, in the part used for agricultural purposes. Species diversity in plant communities, measured by the Shannon-Wiener index, was found to depend on soil type, land use type and phytosociological affiliation. Greater species diversity was observed in communities that developed on mineral soils, are used as pastures, and belong to the class Molinio-Arrhenetheretea. The biodiversity of grassland communities on the Popielno Peninsula is affected by habitat conditions. The relationship between vegetation biodiversity and habitat quality is difficult to grasp due to its multidimensional character. The methods of multivariate statistics may prove useful in this respect.

Phytoplankton in the littoral and pelagial zone of the urban Lake Jeziorak Mały were studied between April and October of 2002, 2003 and 2005. The relation between the abundance and biomass of green algae and selected physiochemical water parameters, species diversity and dominants in the total abundance and biomass of green algae were analyzed. The statistically significant relationships was noted between water temperature, oxygen content, total nitrogen and the biomass of green algae at the coefficient of multiple correlation R = 0.4722. Increased the abundance and biomass of green algae were followed by a decrease in water temperature and increase in oxygen content and total nitrogen concentration during their growth in a temperature range of 10.0oC to 18.8oC. The maximum biomass of green algae was noted in September and the maximum their abundance in October at the highest total nitrogen concentration. In the case of abundance, dominated taxa typical of plankton (Micratinium pusillum, Chlamydomonas spp., Golenkinia radiata, Golenkiniopsis sp., Koliella variabilis and Monoraphidium concortum) and biomass one – filamentous forms as a component of plant periphyton (Spirogyra sp., Stigeoclonium sp. and Ulothrix tenuissima).

2002年4月至10月，2003年至2005年，对城市池湖Mały沿岸和近海浮游植物进行了研究。分析了绿藻丰度和生物量与选定的水体理化参数、物种多样性和绿藻总丰度和生物量的优势之间的关系。水温、含氧量、总氮与绿藻生物量之间的多重相关系数R = 0.4722，均具有显著的统计学意义。在10.0 ~ 18.8oC的温度范围内，绿藻在生长过程中丰度和生物量增加，水温降低，氧含量和总氮浓度增加。总氮浓度最高时，绿藻生物量在9月最大，丰度在10月最大。在丰度的情况下，主要是浮游生物的典型分类群(微藻、衣藻、辐射Golenkinia radiata、golenkinopsis sp.、变异Koliella variabilis和单根藻)和作为植物周围植物组成部分的生物量单丝形态(Spirogyra sp.、Stigeoclonium sp.和Ulothrix tenuissima)。Zmiany iloŚciowe I jakoŚciowe zielenic na tle fizyczno-chemicznych parametrÓw wody w ŚrÓdmiejskim jeziorze jeziorak maŁy

In this study the suitability of various feeds in mass rearing of burbot Lota lota (L.) larvae under controlled conditions was determined. During the rearing the fish were fed with: artificial fodder, live Artemia nauplii and decapsulated cysts of artemia. The experiment continued for 20 days and it was conducted from hatching of the larvae. The initial density of fish during rearing was 1000 individuals dm –3 . Rearing water temperature was set at 12oC. The parameters such as: average body length and height of the larvae and survival after completion of rearing period, were recorded. The Artemia nauplii proved the most suitable for feeding burbot larvae during the initial rearing. Additionally, high mortality of larvae was recorded during the period of filling the swim bladder.
