Opis:
The paper presents the classification of the hydromorfological condition of the Breń River according to the River Habitat Survey (RHS). The research of the hydromorphological assessment of the Breń River, which is a right-bank tributary of the Vistula River and almost entirely flows through the area of the Dąbrowa Tarnowska district was conducted in June 2015. The research sites were situated on the border of the Tarnów Plateau and the Vistula Lowland. The Breń River in these sections flows through rural areas used for agricultural purposes with low-density housing. The analysis of qualitative parameters describing the morphological characteristics were based on two synthetic indices of stream quality: Habitat Quality Assesment (HQA) and Habitat Modification Score (HMS).The calculated numerical values of the two indices proved that the sections of the Breń River correspond with the third and fifth class, which means a moderate (III) and very bad (V) hydromorphological condition.
W artykule przedstawiono klasyfikację stanu hydromorfologicznego rzeki Breń z wykorzystaniem metody River Habitat Survey (RHS). Badania oceny hydromorfologicznej rzeki, będącej prawobrzeżnym dopływem rzeki Wisły i niemal w całości przepływającej przez obszar powiatu dąbrowskiego (województwo małopolskie), przeprowadzono w czerwcu 2015 r. Pomiary wykonywano na Płaskowyżu Tarnowskim i Nizinie Nadwiślańskiej. Rzeka Breń na tych odcinkach przepływa przez tereny użytkowane rolniczo z rozproszoną i zwartą zabudową. Analizy parametrów jakościowych opisujących cechy morfologiczne bazowały na dwóch syntetycznych wskaźnikach jakości cieku dotyczących naturalności siedliska (HQA) oraz przekształcenia siedliska (HMS). Uzyskane wyniki liczbowe dwóch wskaźników pozwalają zakwalifikować badane odcinki rzeki Breń do III i V klasy, co oznacza odpowiednio umiarkowany i zły stan hydromorfologiczny.

Opis:
In an age of changes in species’ geographical ranges, compounded by climatic and anthropogenic impacts, it become important to know which processes and factors influence plant populations and their persistence in the long term. Here we investigated dynamic and fitness components in twelve populations of Malaxis monophyllos (L.) Sw., situated in different geographical (regions) and ecological (type of habitat) units. Although M. monophyllos is a rare species, characterized by highly fragmented, boreal-montane distribution range, in last few decades it successfully colonized secondary habitats in Polish uplands. Our results indicate that M. monophyllos is represented mainly by small populations, which annual spatial and temporal changes might be very high, what affects the ephemeral character of these populations, regardless of the region and type of habitat. This dynamic structure, in turn, is caused by intensive exchange of individuals in populations, as well as by their short above-ground life span. Despite the large range of variation in size and reproductive traits, we can distinguish some regional patterns, which indicate boreal region as the most optimal for M. monophyllos growth and persistence in the long term, and with montane and upland/anthropogenic populations, due to lower reproductive parameters, as the most threatened. Although it should be considered that anthropogenic populations, despite their lower reproductive parameters and instability in the long term, present an intermediate, geographical and ecological character, therefore they may be valuable in shaping, both M. monophyllos’ future range, as well as its potential for response on ongoing and future changes. In general, reproduction is the main factor differentiating of M. monophyllos populations in regions, and we can suspect that it may become the cause of the future differentiation and isolation of these populations, occurring with progressive range fragmentation.

Opis:
Changes in the floristic composition of meadows and pastures may provide information on the human impact on the habitat conditions and intensity of land use. The aim of the study was to present the floristic diversity of the Lolio-Cynosuretum association and its relation with the habitat conditions evaluated using the phytoindication method with Ellenberg indicators. The study was conducted in five river valleys in the years 1999-2012. For the analysis, 100 relevés were selected, which were subject to floristic, habitat (phytoindication), and statistical analysis. In the Lolio-Cynosuretum phytocoenoses, the total number of 178 taxa of vascular plants from 33 families was recorded. It was demonstrated that the differentiation in the floristic composition of Lolio- -Cynosuretum phytocoenoses remains in relation with the habitat conditions, which may be evaluated basing on the ecological preferences of plant species that form the taxa. The species were established as differential for the lower units, that is four subassociations and eight variants.

Celem pracy było przedstawienie zróżnicowania florystycznego zespołu Lolio-Cynosuretum oraz jego powiązanie z warunkami siedliskowymi ocenionymi metodą fitoindykacji z zastosowaniem wskaźników Ellenberga i in. Badania prowadzono w pięciu dolinach rzecznych w latach 1999-2012. Do analizy wybrano zbiór 100 zdjęć fitosocjologicznych, które poddano analizie pod względem składu florystycznego, wymagań ekologicznych gatunków oraz statystycznym. W fitocenozach Lolio-Cynosuretum zanotowano łącznie 178 taksonów roślin naczyniowych z 33 rodzin. Wykazano, że zróżnicowanie składu florystycznego fitocenoz zespołu Lolio-Cynosuretum pozostaje w związku z warunkami siedliskowymi, które można ocenić na podstawie preferencji ekologicznych budujących je gatunków roślin. Gatunki te uznano jako wyróżniające dla niższych jednostek, tj. 4 podzespołów i 8 wariantów.

Opis:
A rare and protected species of the sedge Carex secalina was recorded in Dulsk near Inowrocław (Kujawy-Pomerania Province) in June 2014. It occupied the shores of ephemeral midfield water reservoirs in the complex of intensively used crop fields. Two subpopulations of this sedge with 36 tussocks in total were found. In the first subpopulation, the tussock diameter reached up to 25 cm, with 12–16 generative shoots per a tussock, while in the second subpopulation, the diameter was up to 10.5 cm, with 2–11 generative shoots. The rapid spread of this halophyte species is probably connected with the presence of permanent soil seed bank. This observation indicates a high potential of Carex secalina to colonise new habitats.

Opis:
Changes in habitat conditions in the area of Eastern Poland (Polesie Podlaskie), often associated with anthropopressure, cause a reduction in the number of locations and population size of valuable and rare bog plant species, including a Pleistocene boreal relict, Salix myrtilloides. The aim of this study was to determine the current conditions of occurrence of this species based on the physico-chemical parameters of peatland piezometric groundwater. The results confirm the declining trend in the number of locations and abundance of this species in the past few decades, but at the same time they confirm the wide range of amplitude of the many investigated factors. Among the groundwater parameters studied, the low level of nitrogen fractions, phosphorus fractions, cations, and DOC can be considered to be a set of conditions promoting the preservation of the Salix myrtilloides population. The higher concentrations of phosphates, sulfates, Na, Ca, and Mg as well as higher pH and electrolytic conductivity can be considered to be presumably unfavorable. The lack of significant differences in the values of the piezometric water factors investigated for the sites with different population sizes of the studied species requires the identification of other limiting factors and the implementation of programs for its active protection in Poland.

Opis:
The aim of the study was to examine the morphology, and selected aspects of biology (seed germination capacity, biomass productivity) of reed canary grass (Phalaris arundinacea L.) growing in two locations with different soil conditions near Wrocław. Habitat 1 was characterized by low to moderate contents of nutrients, slightly acidic pH, and low organic matter content in the soil, whereas habitat 2 had soil richer in nutrients, a neutral pH, and higher organic matter content. During the growing period, phytosociological relevés were taken and biometric measurements were performed. In controlled conditions, the germination rate and biomass productivity were estimated in the initial growth stage. The soil conditions that were more favorable for P. arundinacea growth (neutral pH, higher content of organic matter and nutrients) promoted its dominance, and substantially limited the occurrence of other taxa. The floristic composition in the less fertile habitat was considerably richer and the abundance of P. arundinacea was much lower in it, compared with the other location. Phalaris arundinacea plants growing on the nutrient-richer soil were higher and had longer leaf blades and panicles with a greater number of spikelets per panicle than specimens growing on the poorer soil. Seeds collected from plants growing on the more fertile soil exhibited greater germination capacity than seeds from plants originating from the poorer habitat. However, there were no differences in the quantity of biomass produced in the controlled conditions.
Celem pracy była ocena wzrostu oraz niektórych cech biologicznych (zdolności kiełkowania nasion) mozgi trzcinowatej (Phalaris arudinacea L.) występującej w okolicach Wrocławia, na dwóch stanowiskach o odmiennych warunkach glebowych. Siedlisko nr 1 charakteryzowało się niską do średniej zawartością składników pokarmowych, lekko kwaśnym odczynem i niską zawartością materii organicznej, natomiast siedlisko nr 2 posiadało glebę bardziej zasobną w składniki pokarmowe, o odczynie obojętnym i większej zawartości materii organicznej. W trakcie wegetacji wykonano zdjęcia fitosocjologiczne i pomiary biometryczne P. arundinacea. W warunkach kontrolowanych wykonano ocenę zdolności kiełkowania i przyrostu biomasy w początkowym okresie rozwoju. Korzystniejsze dla rozwoju P. arundinacea warunki glebowe (odczyn obojętny, większa zawartość materii organicznej i składników pokarmowych) sprzyjały silniejszej dominacji tego gatunku, co znacznie ograniczyło występowanie innych taksonów. Skład florystyczny siedliska mniej żyznego był znacznie bogatszy, a pokrycie P. arundinacea w płacie znacznie mniejsze niż na siedlisku żyznym. Rośliny P. arundinacea rosnące na glebie bardziej zasobnej w składniki pokarmowe były wyższe, o dłuższych blaszkach liściowych i wiechach oraz z większą liczbą kłosków przypadającą na jedną wiechę niż osobniki rosnące na glebie uboższej. Nasiona P. arundinacea pochodzące z roślin rosnących na glebie zasobnej posiadały większą zdolność kiełkowania niż nasiona roślin z uboższego siedliska. Nie wykazano natomiast różnic w ilości wytworzonej biomasy w warunkach kontrolowanych.

Opis:
Ostericum palustre Besser is a species protected by the domestic and EU laws. In Poland it occurs in about 150 sites one of which is located in the area covered by Natura 2000 “Lisi Kąt”. The population existing there, estimated as 35,000 individuals, covers the acreage of 342 ha. The species persists there mostly in over-dried and transformed-by-meadow-management reed beds with the share of Carex acutiformis and C. gracilis, in phytocenoses of Scheuchzerio-Caricetea nigrae with a large share of mosses, in overgrowing patches of the alliances of Molinion as well as sporadically within reed beds with Carex pseudocyperus. Its share in similar phytocenoses coincides with the reports in literature in the region of the Noteć Valley. In most cases those are heavily disturbed systems, transitional in nature, which must have been the reason for a relatively high level of species variation. The habitat preferences of Ostericum palustre, determined with Ellenberg's indicator values (L, T), correspond to the values optimal for the species. Soil, on the other hand, can be referred to as slightly acid, average fertile and mostly moist.

Opis:
The influence of water conditions on the condition and growth of tree stands has been analysed in the context of the climatic and hydrological functions forest plays. Long observational series obtained for precipitation, outflow and depths below the surface of the water table have been put together with measured increases in the breast-height diameters of Scots pines and the severity of crown defoliation observable in selected tree species growing on the Polish Lowland, in order to determine the overall scope to the reaction stand condition manifests in the face of ongoing variability of water conditions within forest. An overall improvement in the condition of stands over the last 20 years does not disguise several-year cyclicity to changes capable of shaping the situation, i.a. departures from long-term mean values for precipitation totals and groundwater levels. The condition of stands is seen to worsen in both dry and wet years. Analysis of the degree to which pine, spruce and broadleaved stands experience defoliation points to spruce stands responding most to extreme hydro-climatic conditions. Extreme situations as regards water resources were seen to involve a response over two-year time intervals in the case of coniferous stands. Unsurprisingly, optimal growing-season (June-September) precipitation totals correspond with long-term average figures, while being slightly higher for spruce (at 384 mm), than for Scots pine or broadleaved species (375 mm). The relationships reported gain confirmation in analysis of periodic change in breast-height diameter increments characterising Scots pines, whose growth is seen to depend closely, not only on precipitation, but also above all on the depth of the water table in the summer half-year. Optimal depths of the water table proved to be different, being around 20 cm below ground in the case of marshy coniferous forest, 80 cm in wet habitats, and 135 cm in fresh habitats. Depending on the possibilities for water to soak into the rooting zone of trees there were even twofold differences in measured growth increments in Scots pine (as the dominant species in Poland’s lowland habitats). The maintenance of stable water conditions (as the most variable environmental factor in forest) should be an overriding aim of management activity in this habitat. When account is taken of the influence of the state of water resources on biomass production, and then on the intensity of evapotranspiration and the absorption of carbon dioxide from the atmosphere, it is seen how important it is to achieve improvements in water conditions in forests, as such an important factor in combating climate change.

The study objects were Aldrovanda vesiculosa L., an endangered species and fifty five water sites in Poland. The aim of the present work was to test the Self-Organizing Feature Map in order to examine and predict water properties and type of trophicity for restoration of the rare plant. Descriptive statistical parameters have been calculated, analysis of variance and cluster analysis were carried out and SOFM model has been constructed for analysed sites. The results of SOFM model and cluster analysis were compared. The study revealed that the ordination of individuals and groups of neurons in topological map of sites are similar in relation to dendrogram of cluster analysis, but not identical. The constructed SOFM model is related with significantly different contents of chemical water properties and type of trophicity. It appeared that sites with A. vesiculosa are predominantly distrophic and eutrophic waters shifted to distrophicity. The elevated model showed the sites with chemical properties favourable for restoration the species. Determined was the range of ecological tolerance of the species in relation to habitat conditions as stenotopic or relatively stenotopic in respect of the earlier accepted eutrophic status. The SOFM appeared to be a useful technique for ordination of ecological data and provides a novel framework for the discovery and forecasting of ecosystem properties constituting a validation of the SOFM method in this type of studies.

Opis:
There is increasing number of trees dying in large urban agglomerations. The problem is mostly pronounced in the case of street trees. In Polish cities, apart of pollutions generated by traffic, an important factor that causes death of trees is high salt concentration as a result of winter salt application for de-icing of streets. The aim of the study was to assess the growth of limes (Tilia cordata) planted along highly trafficked Warsaw street and exposed, among others, to salt in a form of saline aerosol. The assessment of shoot length, tree height and crown volume, based on the photographic method of the three increment assessments, showed very restrained growth of the studied limes. In the years 2006-2008 the trees performed so poorly as in similar period of 2003-2005 and grew worse than limes form natural habitats. In 2009 we even observed decrease in size of street trees as compared to 2008 which suggests both very bad condition of street habitats and the studied trees. Salt concentration measured on the surface of tree buds and shoots (EC) was higher in street trees than in trees from natural habitats, which indicates that saline aerosol is the source of sodium chloride. We observed highly diversified reactions of individual trees to the whole complex of street conditions. It is therefore recommended to select for propagation individuals from among most tolerant and vigorously growing plants (genotypes) to be used in street planting.

The paper shows the use of Kohonen's network for classification of basaltoides on the base of chemical properties of soils and Polypodium vulgare L. The study area was Lower Silesia (Poland). The archival data were: chemical composition of types of basaltoides from 89 sites (Al2O3, CaO, FeO, Fe2O3, K2O, MgO, MnO, Na2O, P2O5, SiO2 and TiO2), elements contents in soils (Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, S, Ti and Zn) and leaves of P. vulgare (Ca, Cd, Co, Cu, Fe, K, Mg, Mn, Mo, N, Ni, P, Pb, S, Ti and Zn) from 20 sites. Descriptive statistical parameters of soils and leaves chemical properties have been shown, statistical analyses using ANOVA and relationships between chemical elements were carried out, and SOFM models have been constructed. The study revealed that the ordination of individuals and groups of neurons in topological maps of plant and soil chemical properties are similar. The constructed models are related with significantly different contents of elements in plants and soils. These models represent different chemical types of soils and are connected with ordination of types of basaltoides worked out by SOFM model of TAS division. The SOFM appeared to be a useful technique for ordination of ecological data and provides a novel framework for the discovery and forecasting of ecosystem properties.

The morphology of Calamagrostis canescens and C. stricta recorded in the Małopolska Upland (the vicinity of Zbijów Mały, ca. 10 km northeast of the town of Skarżysko-Kamienna, Central Poland) was examined due to intermediate individuals found in sympatric populations of these species. Both putative parents as well as individuals that appeared hybrid-like were found in an extensive, wet hay-meadow. Various vegetative and reproductive characteristics were studied to identify hybrids. Interestingly, Polish accessions of C. ×gracilescens exhibited some degree of morphological intermediacy but resembled C. stricta in spikelet morphology. Branching of the mid-culm, the number of nodes per culm, callus hair length and relative callus hair length are the best characters to distinguish the Polish C. ×gracilescens. AFLP analysis proved to be suitable for detecting recent hybridization events between C. canescens and C. stricta. Analysis of the Bayesian clustering analysis showed that C. ×gracilescens were subjected to gene flow from the C. canescens gene pool as well as from the C. stricta gene pool.
