AbstractĎugova O., Barančokova M., Krajči J., Barančok P.: Soil micromycetes and vegetation changes associated with vegetative cover destruction on chosen localities of Tatry Mountains - first approach. Ekologia (Bratislava), Vol. 32, No. 2, p. 158-172, 2013.Species composition of soil micromycetes and vegetation and its changes associated with vegetative cover destruction were observed in four localities of Tatry Mts. Three research plots with different extent of vegetation destruction on each locality were subjectively chosen: control plots with almost no destruction of vegetation and soil cover (C), partially disturbed plots (B) and plots with high level of soil cover destruction where cover of herb layer was less than 20% (A). Plant species composition of control plots was characterised by the highest level of taxonomical diversity, highest cover of herb and moss layer and represented by alpine herb and grass communities on siliceous bedrock (Juncion trifidi alliance) and alpine and subalpine plant communities on calcareous bedrock (Seslerion tatrae alliance). Devastation of soil and vegetation on B and A plots was performed particularly by decreasing of herb layer cover and changes in species composition: species as Vaccinium myrtillus, Vaccinium vitis-idaea and Calluna vulgaris were absent, whereas Poa alpina, Potentilla aurea, Agrostis rupestris or Avenella flexuosa occurred on devastated plots often. From investigated soils 43 species of soil micromycetes were identified. Control plot of each locality was represented by the highest taxonomical diversity of soil micromycetes. The number of species significantly decreased on plots with successive destruction of vegetation cover (B and A). Several species were identified in just one case (Penicillium digitatum (pers.:Fr.) Sacc., Chrysosporium keratinophilum D.Frey ex J.W. Carmich. etc.). The outcomes showed that soil microorganisms as well as vascular plants react on destruction of soil cover very sensitively.

AbstractNowakowski J.K., Chruściel J., Muś K.: Does mist-netting provide reliable data to determine the sex and age ratios of migrating birds? A case study involving the Great Tit (Parus major) and the Blue Tit (Cyanistes caeruleus). Ekologia (Bratislava), Vol. 32, No. 2, p. 173-185 , 2013.Ringing results of tits caught at two stations on the Polish Baltic coast were used to check if mistnetting could be successfully used to analyse the composition of sex and age classes of migrating birds. Four hypotheses are discussed, describing the distribution of age and sex classes during migration, and the consequences these distributions might have for the catching results. We analysed records of 59 000 Blue Tits and more than 84 000 Great Tits that were caught and we found a similarity in the results of catches at stations 188 km apart, and a higher similarity among catching sites 0.5-16 km apart. These results proved that mist-netting provides reliable data on the sex and age structure of migrating flocks, and that these data can generally be interpreted as representative for at least the area in a radius of more than 10 km. The results also showed a migratory divide through the central part of the Polish Baltic coastline between irruptive Blue Tits in the west and regular partial migrants in the east. Great Tits showed no tendency for irruptions anywhere in the study area. A high correspondence in the age and sex ratio was found for Great Tits and Blue Tits, in particular where both species are regular migrants. We found that the ratios of females and immatures did not differ by more than 1% over many years of study in these areas.

AbstractKuklova M., Kukla J.: Transfer of risk elements in soil-bilberry system. Ekologia (Bratislava), Vol. 32, No. 2, p. 211-219, 2013.Transfer of Al, Cr and Ni in the soil-plant (Vaccinium myrtillus L.) system was examined in four forest ecosystems in the localities Muraň (skeli-humic podzols) and Hliniky (dystric cambisols) in the protected zone of the NP Slovensky raj. In case of Al, the transfer coefficients were low, exceeding 1 only in the litter horizon on the damaged plot in the locality Muraň. The Al content in soils was the highest at a depth of 60-70 cm (10 249 mg kg-1) on the undamaged plot in Hliniky. The amounts of Al accumulated in bilberries were higher than the background value in plants, and they made 11-22% of the maximum Al contents detected in Ooh horizons of the studied soils. Cr on the damaged plot in the locality Muraň displayed higher transfer coefficients (range 1.09-11.3) in comparison with the other plots (0.03-0.59). Considering the value representing the maximum Cr amount detected in Ooh horizon in the corresponding locality as 100%, the content of Cr in bilberries growing on the damaged plot in Muraň was 109%, in contrast to 2% on the damaged plot in Hliniky. The concentrations of Ni in soils exceeded limit values in the surface humus horizons on all studied plots. Ni displayed higher transfer coefficients, exceeding 1 only on the damaged plot in the locality Muraň. Bilberries had accumulated 6-28% Ni in the locality Muraň, and 2-6% in the locality Hliniky of the maximum amounts detected in Ooh horizons of soils. The differences in mean values of transfer coefficients for Al, Ni and Cr were statistically significant (p < 0.05).

AbstractSharif A.J., Elias Z.R., Omar M.F.: Water flow model for the Harrier basin, Kurdistan of Iraq. Ekologia (Bratislava), Vol. 32, No. 2, p. 242-247, 2013.The study includes computer topographic and morphologic simulation of water flow produced using a watershed modelling system that uses hydrologic and physical data from the study area. The DEM module, TIN module, Map module and Hydrologic module were used in this study. A land use data, a soil data and rainfall data were used to produce a curve that illustrates quantity of water flow versus time of water flow across the Harrier basin. The calculated water loss rate can be attributed to a number of factors such as joints, faults, bedding and land use (agriculture and forest). Land use and soil characteristics are both important factors affecting water flow rates. The climate in the Harrier basin is semi-arid. Simulated flow data indicate that the top flow rate is 32 m3/s and that water can reach to the basin outlet in 3 hours and 10 minutes.

AbstractIsajev V., Lavadinović V., Lučić A., Rakonjac L.J.: Serbian spruce (Picea omorca /Panc./ Purkyne) variability in the artificial populations in Serbia. Ekologia (Bratislava), Vol. 32, No. 3, p. 277-282, 2013. A great part of the genetic variation and the potentials of Serbian spruce natural populations have been incorporated in several plantations in the Western Serbia at the site Quercetum fraineto-cerris s.l., Salicetum fragillis s.l and Pinetum nigre s.l. and in other similar occurrences In this way, it becomes much more available for the research and future utilization. The intensive research of the plantations started by the classification of trees into phenogroups which were considered to be significant for forestry and horticulture. The differences between flowering years, plantations and individual trees in the regularity and abundance of micro- and macro-strobiles are major indicators f genetic variability in the reproductive cycle of Serbian spruce. The interaction of environmental characteristics and genotypes of extreme and average trees illustrate the reproductive ability of Serbian spruce on different sites and indicates that this species achieves the coenological and not the ecological optimum at its natural sites. Application of genetic/selection programmes can lead to the production of planting stock of desired and defined properties, which could survive the stress environmental factors, thanks to its morphological and physiological properties.

AbstractPopović V., Lavadinović V., Bjelanović I., Lavadinović V.: Dependence of Douglas-fir mean height on geographic origin of Canadian provenances in seedlings nursery conditions. Ekologia (Bratislava), Vol. 32, No. 3, p. 328-334, 2013. Seed and seedling tests, performed with the aim of acquiring knowledge about the genetic potential of selected provenances, are generally one of the first trials in a complex system of comparative examinations to be conducted upon the introduction of alien tree species. This paper presents the results of the investigation of the dependence of the mean height of 14 Canadian origin Douglas- -fir provenances, originating from latitude 49o 10’ to 51o 35’, longitude 11 o 20’ to 120o 10’ and the altitude of 488 to 1,070 m, on the geographic origin. Understanding the variations in the mean height of a seedling is of major importance for acquiring knowledge on genetic potential of selected provenances, which are one of the key parameters for the introduction of Douglas fir into relevant forest sites in Serbia.

AbstractLavadinović V., Popović Z., Ristić Z., Beuković D.: Threats and international tools for sustainable brown bear (Ursus arctos L.) management. Ekologia (Bratislava), Vol. 32, No. 4, p. 345-351, 2013.Negative relation between humans and large carnivores with unprofitable management caused a decrease in abundance of the latter within their natural habitat. Main reasons for negative attitudes of humans towards large carnivores are damages, fear and unfamiliarity with their characteristics. Brown bear (Ursus arctos) is a European autochthonous large carnivore. Although it is not threatened at the global level, its abundance in Europe is limited to several populations. Protection has an important role in brown bear conservation, since they face different threats, mainly by negative human activities. Conservation of the brown bear is complicated due to its habitats overlapping with the human environment and also because brown bears require large territories. In order to protect brown bears more efficiently, it is important to identify the threats and to conduct the species protection by international recommendations and agreements. In this paper, we analysed brown bear distribution in Europe, abundance limitation factors and international conservation instruments.

AbstractThe first part of this investigation studied complex nature of chemical oxygen demand (COD ) parameter on local and overall effluents, which were obtained from two pulp and paper mills, located in the Northwest region of Russia. Contribution of individual compounds and fractions of matters having different chemical nature to COD for these effluents was established. The second part of this study shows that, qualitative and quantitative characteristics of priority pollutants and their contribution to COD for different pulp and paper mills are not the same, though these mills use similar technologies and produce similar products.
Ground level ozone effects in individual growth phases of central european submountain beech forests
Authors: Kellerová Daniela , Janík Rastislav 
Published: May 2015

AbstractWe observed ground level ozone concentrations on a series of five beech experimental plots, one representing the original stand and the other four generated and modified by cuts of graduated intensity. The study was carried out in a beech ecosystem in the Kremnické vrchy Mts, the Western Carpathian region, in years 1999-2008. The plots, established in 1989, were evaluated and compared statistically before and after the cutting modification in 2004. The level of significance of the effect of this intervention was 99% on the plot representing small-area clear-cut and on the plot treated with medium cut. Differences, though not significant, were also found in the other plots. Apart from the effects due to the stocking reduction, the whole post-intervention period was characterised with the influence of progressively increasing average air temperatures and similarly increasing ozone concentrations. Globally, the ozone concentrations on all plots were lower (average value 39 μg m

AbstractVanková V., Petluš P.: Water temperature influence on selected properties of surface river water throughout the year (river Nitra). Ekológia (Bratislava), Vol. 33, No. 2, p. 151-159, 2014.Assessment of chosen surface water properties was realised as a part of broader research on environmental aspects of urban environment. Analyses of selected physical and chemical water properties, oxygen and temperature regime, neutralisation capacity, selected nutrients and measurements of air temperature was done in monthly intervals during 2012 at three localities. Two of the assessed localities are at river Nitra: Nitra Communal Services and housing estate Chrenová I. The third locality is the oxbow lake of Malá Hangócka river at Nitra City Park. We have assessed the volume of oxygen concentration (O2, mg/l) and oxygen regime, phosphates (P-PO4 -3, mg/l), ammoniac nitrogen (N-NH4 +, mg/l), nitrites (N-NO2 -, mg/l), pH and water temperature (°C) from the collected samples. Out of these analyses the values of the above mentioned indicators, their annual fluctuation and water quality of observed localities were obtained. The influence of human activities on water properties and its quality was further assessed. Statistical methods such as two-factor dispersion analysis without replication and correlation coefficient were applied to validate the correlation of selected surface water properties, water and air temperature and to compare observed localities.

AbstractThe identification of parameters to monitor the ecosystem services delivered at a site is fundamental to the concept’s adoption as a useful policy instrument at local, national and international scales. In this paper we (i) describe the process of developing a rapid comprehensive ecosystem service assessment methodology and (ii) test the applicability of the protocol at 35 long-term research (LTER) sites across 14 countries in the LTER-Europe network (www.lter-europe.net) including marine, urban, agricultural, forest, desert and conservation sites. An assessment of probability of occurrence with estimated confidence score using 83 ecosystem service parameters was tested. The parameters were either specific services like food production or proxies such as human activities which were considered surrogates for cultural diversity and economic activity. This initial test of the ecosystem service parameter list revealed that the parameters tested were relatively easy to score by site managers with a high level of certainty (92% scored as either occurring or not occurring at the site with certainty of over 90%). Based on this assessment, we concluded that (i) this approach to operationalise the concept of ecosystem services is practical and applicable by many sectors of civil society as a first screen of the ecosystem services present at a site, (ii) this study has direct relevance to land management and policy decision makers as a transparent vehicle to focus testing scenarios and target data gathering, but (iii) further work beyond the scale investigated here is required to ensure global applicability.

AbstractThe experiment was set up in the forest ecosystem with diverse vegetation zones in the area of Istria and the Croatian Littoral. Research included the following systematic soil units: lithic lepto-sols, rendzic leptosols, rendzic leptosols - eroded, mollic leptosols, chromic cambisol and chromic luvisols. The average quantity of the forest litter in the studied systematic soil units reaches 13.36 t/ha (Tables 1-3). The “wealth” of organic matter in the studied soil units can be presented with the following series: chromic cambisols (CMx) > mollic leptosols (LPm), organogenic, rendzic leptosols (LPk) > lithic leptosols (LPq) > chromic cambisols (CMx) - Terra rossa, chromic luvi-sols (LVx) > rendzic leptosols (LPk) - eroded. As expected, the lowest value of total nitrogen was found in the lithic leptosols in relation to almost all the other soils, except when compared with chromic cambisol and rendzic leptosols (p ⋋ 0.05). The statistically justified higher values of the percentage share of P

Published: May 2015

AbstractThis article investigates response of vegetation on gravel bars to management measures and floods. The management measures consisted of the partial removal of gravel and vegetation cover, and were applied to six gravel bars on the Ostravice River, Czech Republic. Unexpected floods occu-rred in 2010, with the amplitude of 5- to 50-year repetition. Research of vegetation on the gravel bars consisted of vegetation survey before the management works; the monitoring of vegetation development over the following year and the verification of the relationships of species diversity, successional stages and the biotope conditions with the help of multivariate analysis (detrended correspondence analysis). Vegetation on the gravel bars was at different successional stages, and had higher diversity and vegetation cover before the management measures and floods. The mul-tivariate analysis revealed a shift toward initial successional stages with high demand on moisture, temperature and light after both management measures and floods.

AbstractMany authors (Akbari, Taha, 1992; Čaboun, 2008; Klein, 2013; Keresztesová, 2013) proved the influence of vegetation on microclimate as well as on the decrease of heat islands. We were interested in how different ratio of vegetation and open spaces influences microclimatic factors. From April to July 2012 microclimatic factors of two different localities with respect to various ratios of vegetation and open spaces were observed in Nitra, Slovakia. More specifically we observed the air temperature, relative air humidity and surface temperatures of four selected points in both localities. We have found out that in the park, i.e. in the locality with a higher portion of vegetation than open space was the course of temperatures more balanced, thanks to the attribute of vegetation to keep a stable microclimate. We have not observed any major Differences between the monitored points variously located in the vegetation in one locality, but on the other hand, we have observed remarkable differences between the two monitored localities. We may allege that the ratio of vegetation and open spaces makes significant contribution to microclimatic conditions of urban environment.
Soil Heterogeneity Reflected in Biogeography of Beech Forests in the Borderland Between the Bohemian Massif and the Outer Western Carpathians

Published: May 2015

AbstractSoil environment characteristics naturally affect the biogeographical classification of forests in central Europe. However, even on the same localities, different systems of vegetation classification de-scribe the forest types according to the naturally dominant tree species with different accuracy. A set of 20 representative natural beech stands in the borderland between the Bohemian Massif (Hercyni-an biogeographical subprovince) and the Outer Western Carpathians (Westcarpathian subprovince) was selected in order to compare textural, hydrostatic, physico-chemical and chemical properties of soils between the included geomorphological regions, bioregions and biotopes. Differences in the soils of the surveyed beech stands were mainly due to volume weight and specific weight, maximum capillary capacity (MCC), porosity, base saturation (BS), total soil nitrogen (N

AbstractThis paper presents the perspectives of FORKOME model use regarding the simulation of fre and its impact on forest stands. The calculation of probability of forest fres and predicting its effect on forest stands are analysed as well. The model is supposed to examine the impact of fres on pine stands, which ultimately leads to a decline in the viability of those trees. As a result of fre activity there were determined the following categories of trees - undamaged, slightly damaged, heavily damaged and destroyed. Moreover, by conducting simulations on forests with Scots pine
