Potential factors affecting the occurrence of filamentous algae include the morphometry of water bodies, the type of substrate and physicochemical conditions of the habitat. This study attempts to describe the individual filamentous algae species recorded in Poland, taking into account the trophic and ecological characteristics based on our own research and available literature data. Filamentous algae attached to the substrate as well as those forming free-floating patches (loose or dense mats) and crusts occur in all types of water bodies. Among the representatives of filamentous algae species, Cladophora have the greatest time-spatial range for they grow abundantly in all types of water bodies. In other parts of Poland, Cladophora species are most common in rivers and shallow lakes. In the typical filamentous algae community, Cladophora, Spirogyra and Oedogonium occur with the highest frequency; Zygnema, Mougeotia, Microspora and Rhizoclonium are also present, but with smaller frequency. According to our studies, distribution of filamentous algae species is correlated with the eutrophic index (PO43-, N-NO3-, Chl a), chlorides of anthropogenic origin and TDS.

Przedstawiono warunki optymalizacji procesu wytwarzania ekstraktu z biomasy glonów na potrzeby przemysłu kosmetycznego. Proces optymalizacji omówiono w trzech obszarach: pozyskiwania biomasy ze środowiska naturalnego, ekstrakcji za pomocą ditlenku węgla w warunkach nadkrytycznych oraz wymogów formalnych, umożliwiających zastosowanie ekstraktu dla celów komercyjnych, w tym jako składnika preparatów kosmetycznych.

The occurrence of algal-cyanobacterial metaphyton mats in field (Konojad village) and artificial ponds (Poznań city) was investigated in the Wielkopolska region. The surface area of algal mats ranged between ca. 45% (natural pond) and 10% (artificial pond) of the total water surface, and the mats occurred from the water surface to the bottom; the algal diversity was similar in both types of ponds, i.e. about 10 taxa. The most frequently recorded and dominant taxa in small water bodies were: Spirogyra spp., Cladophora fracta in the artificial pond and Oedogonium spp., Cladophora rivularis in the natural pond. The dynamics of macroalgae demonstrated a pattern comprising different phases of taxa dominance. For example, April regarded as the first phase was characterized by a small amount of metaphyton, represented by Tribonema and Ulothrix taxa. In May, these species disappeared and were replaced by: Oedogonium spp. and Cladophora spp. which formed large aggregations in the field pond, and Spirogyra spp. which abundantly proliferated in the artificial pond. From June, however, Oedogonium and/or Cladophora significantly dominated in the mat structure and at the same time covered a large area of the water surface. The algal community was dominated by common algal taxa, among which single filaments of other taxa could also occur.

The paper presents virtual model of the unit for strip till, fertilization and corn sowing, developed by the Industrial Institute of Agricultural Engineering (PIMR) in Poznan under the project PBS1/B8/4/2012. We discuss the construction of the unit with a particular attention to the position of fertilizer seeder, which sows fertilizer behind soil loosening teeth, and corn seeder, which sows corn in strips of cultivated soil.

Ulva flexuosa subsp. pilifera previously known from northern Poland, from the channel near Szczecin and ponds near Łódź, has recently been found in the Malta Reservoir in the Wielkopolska (West Poland) region. Specimens collected in the Wielkopolska region were examined in detail, also under a transmission electron microscope (TEM). The morphometric analysis of Ulva thalli (both young and mature specimens) was performed in order to study the differences in the ultrastructure of vegetative cells. Rectangular cells in young thalli measured from 32.21 - 55.81 μm to 20.24 – 35.12 μm, and they formed clear longitudinal rows, while cells in the mature specimens ranged from 25.09 – 47.66 μm to 18.90 – 31.56 μm. This study indicates that vegetative cells of the mature thalli show tendency towards distortions of both the longitudinal and transverse cells arrangement. This distortion is determined by the development of possible carbonate calcium crystals on the thalli surface. The ultrastructural analysis (TEM) confirmed that the structure and placement of thylakoids is genus/species specific.
