Undertaken studies on diversity and prevalence of yeast-like fungi aimed at presenting the role of a hydrophyte treatment plant in cleaning municipal wastewater from potentially pathogenic fungi. One hundred and six isolates of fungi were obtained. The highest diversity of species was found in the sedimentation tank and in I and II reed beds. The dominating species were: Trichosporon beigelii, Candida albicans, Candida glabrata, Candida dubliniensis, Candida krusei, Candida utilis and Candida lipolytica – isolated also from hospitalized patients. The number of fungal cells decreased progressively from uncountable in the sedimentation tank to 2,060 cfu/dm³ in the polishing pond. Reduction of the number and changes in species composition of yeasts like fungi take place in the hydrophyte treatment plants.

In the southern part of Poland, ground beetle fauna was studied in the first large-scale Bt maize experiment. The aim of this study was to determine the long term impact of the Bt maize cultivar in comparison to conventional plants, on selected non-target arthropods. The DKC 3421 YG cultivar (Bt maize) and the respective isogenic non-Bt varieties (DKC 3420) were cultivated at two locations: (a) Budziszów near Wrocław and in Głuchów near Rzeszów in the south-eastern region of Poland, in the 2008-2010 growing seasons. For comparative analysis, two additional non-Bt cultivars sprayed with a lambda-cyhalotrine insecticide were also included. To monitor population density of surface-active invertebrates of the Carabidae family, eighty pitfall traps were used at each location. The average number of ground beetle populations in the Bt-maize cultivar DKC 3421 YG did not significantly differ from the number of beetles in the conventional ones. Significant differences between the number of beetles occurred on individual dates only. Usually, these differences related to the considerably smaller total number of beetles in the whole replication. Probably, the variation in the number of beetles was caused by climatic factors or the terrain layout, therefore it cannot be related to the cultivar effect.

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 10.0℃ to 18.8℃. 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).

Soil waterlogging is among abiotic stresses that influence species composition and productivity in numerous plant communities. The aim of the study was to find answer to the question of how waterlogging caused by beavers’ activity induces quantitative and qualitative changes of vegetation and soil seed bank levels of variable-moist meadows. An immediate effect of the waterlogging at the level of vegetation was the decline in species richness and a decrease in the values of the biodiversity index. Water stress inhibited growth and development of plants already present and, primarily, impeded recruitment of new individuals of species characteristic of variable-moist meadows, e.g. Cirsium rivulare, Filipendula ulmaria and Lythrum salicaria, which were replaced by Carex acutiformis. Prolonged waterlogging did not induce equally substantial changes in the soil seed bank as in the vegetation. Both in the waterlogged and control patches, slightly decreased species richness and biodiversity index were recorded. After waterlogging withdrawal, the reserves of the soil seed bank were slightly higher than the initial values. The differences were not statistically significant. In the waterlogged patch, the qualitative floristic similarity between taxa identified in the soil seed bank and vegetation cover declined, which was evidenced by the value of Jaccard’s index decreasing from 0.46 to 0.36. A reverse relationship was found in control patch, where the value of the similarity index slightly increased from 0.41 to 0.48.

The food retail trade in Poland is undergoing significant structural changes. The changes basically consist in a dynamic increase in the number of large-format stores, and also in the processes of integration and concentration of trade. In the food trade there are also qualitative changes taking place, in the form of implementing innovations and modern methods of managing the stores. These questions are brought up in this article.

Ruminants are a group of animals that process and assimilate their food in a unique manner. The functioning of the digestive tract of these animals is closely related to the abundance and composition of microbes in the forestomach, which is a complex ecosystem of bacteria, protozoa and fungi. Microorganisms present in the rumen, and in particular their effect on physiological processes in the body, influence the animal’s physical condition and state of health. Microbiological examination of rumen microbiota ecology is hindered by a lack of selective growth media, as well as by difficulties in isolating bacteria in vitro and accurately identifying them. The aim of the study was to evaluate the effect of food consumed by red deer (Cervus elaphus) on the diversity of their rumen microbiota. Microbes were compared in two study periods. In autumn the animals’ diet came exclusively from natural plant sources, while in winter, supplementary feeding was introduced, including specially prepared fodder. The study showed that in deer that did not receive the special fodder in winter, but only natural plant components, the abundance of bacterial flora decreased significantly compared with what it was in autumn, unlike in animals that did receive the fodder, whose composition and caloric value substantially increased the activity of rumen microbes. In winter, changes in proportions of different morphological forms of rumen bacteria were observed, as well as a decline in their total number, particularly in the animals that did not receive the pellets. A similar decline was also observed in the populations of yeasts and protozoa in winter. To sum up the results of the study, the use of the specially prepared high-calorie fodder in winter was shown to influence the rumen ecosystem of red deer. The most significant factor improving the condition of deer receiving supplementary fodder during this period is the stabilization of bacterial flora in the rumen, which directly contributes to the efficiency of digestion.
