Article
Full-text available
Baltic Sea is one of the World's most oxygen-depletes seas, so the region requires urgent mitigation measures to significantly reduce nitrogen and phosphorus inputs from land through rivers, which cannot be achieved without large-scale restoration of wetland buffer zones. The manuscript summarises the findings of the discrete choice experiment aime...

Full-text available
Fertiliser use in agriculture increases the non-point pollution of waters with nitrogen (N) and phosphorus (P). Wetland buffer zones (WBZs) are wetland ecosystems between agricultural lands and water bodies that protect surface waters from non-point source pollution. We assessed how vegetation harvesting within WBZs impacts their N and P removal ef...

The Floating Fern, Salvinia natans, is a species of fern associated with stagnant water, primarily oxbow lakes, but also ponds clay pits, low-flow drainage canals and ditches. In these ecosystems, it most often forms phytocoenoses of Salvinio natantis-Spirodeletum polyrhizae. Due to anthropogenic changes in the river valleys where this species and...

Mesotrophic rich fens, that is, groundwater-fed mires, may be long-lasting, as well as transient ecosystems, displaced in time by poor fens, bogs, forests or eutrophic reeds. We hypothesized that fen stability is controlled by plant stress caused by waterlogging with calcium-rich and nutrient-poor groundwater, which limits expansion of hummock moss...
Article
Wetland buffer zones (WBZs) are riparian areas that form a transition between terrestrial and aquatic environments and are well-known to remove agricultural water pollutants such as nitrogen (N) and phosphorus (P). This review attempts to merge and compare data on the nutrient load, nutrient loss and nutrient removal and/or retention from multiple...
Article
Full-text available
Large-scale re-establishment of wetland buffer zones (WBZ) along rivers is regarded as an effective measure in order to reduce non-point source nitrogen (N) and phosphorus (P) pollution in agricultural catchments. We estimated efficiency and costs of a hypothetical establishment of WBZs along all watercourses in an agricultural landscape of the low...
Article
Background: In fens, plant species composition is predominantly controlled by two environmental factors: root anoxia and low nutrient availability. Aims: We asked how these filters were reflected to the functional structure of plant communities in natural and drained rich fens. Methods: We analysed traits related to species response to anoxia and n...
Article
Full-text available
Little is known about the vegetation dynamics of fens, and especially of hydrologically undisturbed examples. We described the vegetation of an undisturbed mesotrophic rich fen (percolation mire) in 2006-2008 and 2016 and compared our results with vegetation records from the 1980s to identify any longer-term changes. Eight vegetation types were dis...
Article
Full-text available
A rapidly growing human population and the extirpation of numerous species make modern wetlands among the most threatened of ecosystems. One of the endangered wetland plants in central and eastern Europe is Betula humilis. B. humilis forms comparably abundant populations on both well-preserved and drained fens; thus, we aimed in this paper to inves...

Erratum to: Hydrobiologia DOI 10.1007/s10750-013-1783-3Due to an unfortunate turn of events, the Acknowledgments section was omitted in the original publication causing a funding agency not to be properly acknowledged. The correct information is published here and should be treated as definitive by the reader.
Article
Full-text available
The aim of the present study was to use the analysis of surface water chemistry to understand vegetation succession pathways in terrestrializing polyhumic lakes. We hypothesized that Sphagnum mire development was accompanied by a decrease in the mineral content in water. A total of 111 vegetation plots along 23 transects were analysed in 11 lakes a...
Article
Full-text available
We explored the background of differences in long–term stability between two parts in an undisturbed mire system (Rospuda fen, NE Poland). We re-constructed the Holocene history of the mire and compared it with current vegetation, water level dynamics, water chemistry and nutri-ent availability in two basins: A, where the mire terrestrialised a dee...
Article
Full-text available
The steppe vegetation has been destroyed to the greater extent than any other type of zonal vegetation in Europe. Ancient mounds (barrows, kurgans, tumulus) persisted in the large-scale, intensively cultivated land and constitute the isolated micro-hot spots of steppe biodiversity. In the present paper floristic value of 26 kurgans among 120 visite...
Article
The list of verified and confirmed Betuia humilis (Betulaceae) localities in Poland is presented. The paper presents the results of a literature survey (1945-2008) and field verification (2004-2012).
Article
Full-text available
Plant species diversity in Eurasian wetlands and grasslands depends not only on productivity but also on the relative availability of nutrients, particularly of nitrogen and phosphorus. Here we show that the impacts of nitrogen:phosphorus stoichiometry on plant species richness can be explained by selected plant life-history traits, notably by plan...
Article
Full-text available
The historical development of the hydroseral vegetation of three humic lakes was studied. We applied a combination of methods to reconstruct the past vegetation (plant macroscopic remains, peat decomposition, sediment chemistry and radiocarbon dating). The contemporary environment of these lakes was assessed by vegetation and water chemistry analys...
Article
Full-text available
Betula humilis is an endangered plant species in Central Europe. In order to protect this species, it is necessary to document its genetic diversity in this region and to identify areas for conservation prioritisation. As molecular investigations conducted throughout the ranges of many plant species have shown that the highest genetic diversities a...
Article
Full-text available
Habitat studies were conducted on three rare plant communities dominated by Nuphar pumila, Nymphaea candida and Hydrilla verticillata in lakes of north-eastern Poland. The comparison of habitat properties of these three types of phytocoenoses with those of Nuphar lutea common in the area under study was also performed. It was demonstrated that the...
Article
Betula humilis is a shrubby species growing on fen peatlands, with a biogeographical range extending from Germany to Central Siberia. The aim of this study is to revise the variability of vegetation with B. humilis in Central Europe and to assess its ecological status. The results explain divergent observations of various authors and present the va...

Paper available from: http://www.tandfonline.com/eprint/A96puTqApZHa6zDC4iMT/full In Europe, 21% of vascular plant species are threatened. One of the endangered taxa is the shrub birch (Betula humilis Schrk.) The main reason for its disappearance is the development of brushwood and forest canopy as a consequence of the human management of the envir...
Article
Full-text available
The probability of population extinction seems to differ within the species range. Populations occupying former glacial refugia could harbor substantial genetic resources, hence they should be less prone to extirpation. It was hypothesized that the shrub birch Betula humilis could have survived the Last Glacial Maximum (LGM) at the current southwe...
Article
Full-text available
Although conservation of percolation mires is very important for the European biodiversity, our understanding of their functioning is still insufficient, as most of the studied sites are to some extent degraded. We present a study on the relationship between vegetation patterns, hydrochemical gradients and water level fluctuations carried out in th...
Article
The aim of this study was to determine and compare the floristic value of kurgans distributed over an area of approximately 32,100 km spreading in four climatic-vegetation zones (steppes and forest steppe) in southern Ukraine. Among the 450 kurgans visited during the growing seasons 2004–2010, 106 best preserved kurgans were investigated. Of 721 sp...

The habitats of 356 phytocoenoses dominated by 15 species of aquatic plants were investigated. Among the properties of water, Na+, pH, total Fe, Ca2+, NO3−, SO42−, hardness and COD-KMnO4 were the most important in differentiating the habitats of the phytocoenoses studied. Considerable physicochemical differences were found between the waters of the...
