    water retention
    Opis:
    Based on results concerning the forest impact on water cycling an attempt was undertaken to evaluate water retention in forests. The economic value of water retention was established assuming the cost of water storage in small reservoirs built in forest areas. Calculations did not account for differences resulting from different functions of naturally retained water and that stored with the use of technical methods. Considering volume and time of water retention in forests, the annual value of natural water retention in forests calculated per average hectare of the country area was estimated at 800 zł.
    Wobec potrzeby racjonalizowania gospodarowania zasobami leśnymi podjęto próbę oceny i wyceny naturalnych retencyjnych właściwości terenów leśnych. Ocenę wpływu lasu na wielkość i czas spowolnienia odpływu wody przeprowadzono na podstawie wyników długoletnich badań w małych zlewniach rzecznych. W procesie retencjonowania wody wyróżniono wpływ lasu na zwiększenie ogólnej ilości odpływu i udziału odpływu półrocza letniego w odpływie rocznym oraz zmniejszenie nierównomierności odpływów rocznych i wielkości wezbrań kulminacyjnych. Obszary leśne magazynują w średnim roku niemal 70 mm wody w różnych formach. Ogólna, sumaryczna wielkość retencji związanej z lasem, wyznaczona w skali roku dla statystycznego hektara powierzchni Polski (28% lesistości), wyniosła 193,5 m³. W dalszej kolejności określono koszty związane z magazynowaniem wody w małych zbiornikach retencyjnych wybudowanych w ostatnich latach na terenie leśnym, przyjmując 4,15 zł·m-³. Wycenę ekonomiczną wody retencjonowanej przez las obliczono jako iloczyn jej objętości i ceny. Wartość ekonomiczną naturalnych właściwości retencyjnych lasu dla statystycznego hektara powierzchni Polski można oszacować na 800 zł·rok-¹ oraz na 2668 zł w ciągu roku z 1 ha lasu. Ze względu m.in. na różne znaczenie naturalnej retencji wodnej lasu i efektów retencyjnych, osiąganych w wyniku inwestycji technicznych, należy tę kwotę traktować jako orientacyjną.

    Opis:
    The study concerned changing status of water retention within an unique nature complex of the Białowieża Primeval Forest. The retention was evaluated based on an analysis of research results on water outflow from the lowland catchment of the river Łutownia – representative for physiographic conditions as well as those of habitats and tree stands in Poland’s part of the Forest. The catchment in the lowland hydrometric dissection at the Pogorzelce village – Old Białowieża Wilderness, covers the area of 120.1 km2 with natural flow conditions preserved. A unified sequence of measurements carried out since 1966 using unchanged methodology with respect to precipitation, air temperature and forest management status allowed to separate different phases of changes occurring in water resources of this protected forest complex. There were appraised periodical runoff changes and cycles including a decrease in water resources which occurred at the turn of the century. The retention capacity of the catchment was determined based on periodical changes in rainfall-runoff relations and the ongoing process of deteriorating water conditions of forest ecosystem was interpreted.

    Opis:
    Recurvoides infernus sp. nov., one of the oldest representatives of the superfamily Recurvoidacea (Foraminifera), is described from a thin black claystone overlying the manganese deposits of the Krížna Unit in the Western Tatra Mountains (Poland). These manganese carbonates/silicates were laid down around a shallow−water exhalative submarine hydrothermal vent that was active in the early Toarcian. The microfossils are possibly the first described Jurassic foraminifera associated with hydrothermal vents. The assemblage is characterized by a high abundance and dominance of this new species. The primary lamination of the black claystone, the lack of any macrofauna, and an elevated TOC content point to oxygen−deficient conditions during sedimentation of these deposits. Furthermore, the nearly exclusive occurrence of agglutinated foraminifers suggests a low pH level. It is likely that the foraminifers colonized vent−related bacterial mats which acted as a rich and stable food source. Modern shallowand deep−water hydrothermal vents may represent similar habitats.

    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.

    Opis:
    We describe the new foraminiferal genus and species Plectoeratidus subarcticus n.gen. n.sp., from the Upper Cretaceous deep-water deposits of the Kviting and Kveite formations in the western Barents Sea. The genus is characterised by its planispiral-biserial-uniserial chamber arrangement, terminal aperture and lateral compre- ssion. The biometric analysis of test ontogenesis has been applied to document its dimorphism attributed to megalospheric and microspheric generations. This taxon may represent an evolutionary transition between the Cretaceous genera Spiroplectammina or Bolivinopsis and the Cenozoic genus Eratidus. The taxon appears to be endemic to the flysch-type agglutinated foraminiferal assemblages in the Norwegian Sea area.

    Opis:
    Although beneficial properties of mineral waters are acknowledged by law in many countries, the use of water for medicinal purposes is not universally accepted. Notably numerous waters (especially mineral and curative ones) have high concentrations of mineral and trace elements. These mineral waters are common on the market and their availability is not regulated by law. Due to the hazard of overdosing, quantification of trace elements and minerals seems to be necessary. The World Health Organization, European Standards and Polish Standards recommend different methods for elemental determination, i.e. spectrometry, photometry for zinc determination, colorimetry or spectrometry for copper, and ionic chromatography for calcium, chloride and fluoride. In this paper, alternative, electrochemical methods have been applied to determine zinc, copper, calcium, chloride and fluoride in most popular natural and curative waters from southern Poland. The determined elemental content varied between 3.85-33.54 μg L-1 for zinc, 85-15.33 μg L-1 for copper, 2.8-2433.63 mg L-1 for chloride, 0.4-1.66 mg L-1 for fluoride and 11.05-478.48 mg L-1 for calcium. The voltammetric method was tested according to the validation procedures, taking into account the following parametes: linearity range, limit of detection and limit of quantification and precision. The results show that the applied electroanalytical methods are suitable for determination of the selected elements in waters of natural origin, ensuring low instrumental and analysis costs while providing results comparable with ones achieved with recommended methods.
