    Pollution of aquatic ecosystems continues to be a problem in developed countries, resulting in a reduction in the biodiversity of organisms associated with these habitats. In many countries, macrophyte indices are used to assess surface water pollution. They apply both to determining the ecological status of lakes and rivers. The presence of aquatic plants informs, among others, on the level of water eutrophication, and the analysis of the content of metals in plants indicates the pollution of water ecosystems with metals. Failure to reach the key objective of the Water Framework Directive, i.e. good water status, by 2015 forces the search for new ways of water management, including cheap and environmentally friendly methods of treatment of contaminated and used waters. The results of research on the possibilities and limitations in the functioning of individual species of aquatic plants in polluted and used waters allow for the rational selection of plants for phytoremediation of aquatic ecosystems. The aim of this review was to discuss the biological features of common mare's tail and its habitat and to determine the plant’s ability to develop in waters contaminated with biogenic compounds and metals, and to determine its ability to uptake metals measured by the effectiveness of removing contaminants. It was found that mare's tail occurs in waters with variable concentration of biogenic compounds and metals. Irrespectively of the concentration of nitrogen, phosphorus and potassium in the plant growth medium, each introduction of lead, zinc, copper, manganese and iron into the plant growth medium, in quantities corresponding to the limit values for V class water quality, caused their increased uptake by mare's tail. The accumulation of these elements reflects the state of water pollution with metals. Nevertheless, water pollution with some metals causes the biomass of the plant to be reduced. Due to high efficiency of removing various impurities by mare's tail, the plant can be used in the hydrophytic systems of wastewater treatment but its best use is for the purpose of after-treatment of municipal wastewater.

    Roadside Tree-Lined Alleys in Wolin Commune Open Landscape. Part I
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2018) Dusza-Zwolińska, Elżbieta; Gamrat, Renata; Saran, Edyta; Department of Ecology, Environmental Protection and Management, West Pomeranian University of Technology, Szczecin, Poland; Department of Ecology, Environmental Protection and Management, West Pomeranian University of Technology, Szczecin, Poland; Department of Ecology, Environmental Protection and Management, West Pomeranian University of Technology, Szczecin, Poland
    In the years 2016–2017, dendrological and landscape studies were carried out in the selected area of the Wolin commune. Five alleys with a total length of 16 km between the forest ecological corridor and the Szczecin Lagoon were selected for the study. The aim of the study was to confirm the fulfilment of the natural and protective functions of these trees in the definition of ecological areas. The compositional-spatial features of the roadside have also been analysed. The study trails consisted of seven tree species ranging from 100 m to 1800 m, the most numerous of which were Acer platanoides (458) and Quercus robur (258). In terms of natural values, Acer platanoides (24–30 points) and Tilia cordata (23–27) gained the highest values, among the alleys – planting no II (26 points), I (22), III and V (20). The absence of traces of devastation of roadside trees and the presence of 15 wind turbines, would indicate a high ecological awareness of farmers and understanding for the use of renewable energy. Assessed ecological functions of alleys and their location indicated on their significant contribution to the conservation of biodiversity and protective functions. The health condition of the investigated alleys points out no significant threat factors. Biometric measurements of trees in the analysed alleys showed that the tree-lined roadside meets the requirements of ecological areas. Despite of the presence of wind turbines, which are strong visual dominant, the value of the studied area was highly valued, mainly due to the compositional and landscape diversity.

    Zróżnicowanie zbiorowisk ląkowych w dolnej części doliny Iny na tle warunków siedliskowych

    In the years 2000–2002 floristic and phytosociological investigations were carried out around of eleven permanent sites in the Ina River valley between villages Sowno and Przemocze. Nineteen phytocoenosis on the eleven humidity habits were selected. Ascertain ecotone zone of vegetation were dependent on site. The biggest surface were occupied by the floral assemblage situate the most closer to the Ina River on the fresh and wet habitation. Next, along with distance accrue ascertain occurrence of strong wet and wet habitation as well as dry seasonally humidified habitation on the higher areas of researched area. The high value of synanthropisation and apophytisation indexes indicated the negative changes on the meadows communities. Two protected plant species and ten protected animals species (including insects, amphibians, birds) were found on the studied area.
