Red deer occurs predominantly in vast areas of forest, i.e. mainly in the mountains bordering this country and several large forest units in the interior. The range of this species has been increasing along with the size of its population. Areas of its permanent occurrence may be generally characterized as regions largely covered with deciduous and coniferous forests and pastures, and regions with a more diverse landscape. Red deer does not occur in areas that are mainly arable or urban, or in areas covered with extensive water bodies and wetlands. As these animals prefer large forests, they occur mainly at high altitudes where the terrain is rugged. The Eurasian elk permanently occurs in the Czech Republic in a single area located between the state border and the right bank of the Lipno Dam. Its home range has been diminishing, presumably along with its numbers. The area of its permanent occurrence is characterized by an abundance of coniferous trees, some pastures and water bodies. The Eurasian elk does not occur in areas covered with arable and urban land but also surprisingly in areas with mainly deciduous forest. Both species prefer high altitudes, but Eurasian elk prefers areas with little difference in the terrain vertically.","PeriodicalId":11931,"journal":{"name":"European journal of environmental sciences","volume":"7 1","pages":"50-62"},"PeriodicalIF":0.8,"publicationDate":"2017-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42994894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chamber allows on-line determination of number/mass size distribution of aerosol particles formed by dispersion and subsequent sampling of size-segregated particles on filter media. The samples tested were lignite, power plant flue ash and overburden soil from the Nastup coal strip mine in Northern Bohemia. About 20 mg of the individual samples were pneumatically dispersed by 0.5 liter of pressurized air inside the chamber under defined temperature and humidity conditions. Then the dynamics of aerosol size distributions was recorded using an aerodynamic particle sizer with a frequency of 5 seconds. The lignite and flue ash contributed most to the mass of atmospheric aerosol particles smaller than 10/2.5 micrometer – PM10/ PM2.5. The re-suspended mass of the samples varied between 0.001% for overburden soil and 0.32% for mine road soil. The aerosolized lignite and flue ash samples, sampled by a Harvard Impactor and a Personal Cascade Impactor Sampler, revealed that the ash contained higher amounts of fine particles than the lignite and subsequent chemical analyses, carried out using SEM-EDX, reveals that the PM2.5 fraction formed by dispersion of the ash samples had the highest content of sulphur, and PM10 was dominated by Si. PM10 was closest to mullite, while the PM2.5 fraction contained sulphides, pyrites, pyrrhotites and polytypes of sulphide. The PM1 fraction was dominated by quartz glass. The fractions of sizes 2.5–1 μm and 0.5–0.25 μm were dominated by Si and S, respectively.","PeriodicalId":11931,"journal":{"name":"European journal of environmental sciences","volume":"7 1","pages":"14-26"},"PeriodicalIF":0.8,"publicationDate":"2017-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47941286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methods are based on dividing a monitored area into sectors using a common compass rose and obtaining hourly average concentrations of pollutants and relevant data on wind direction and speed over at least three seasons of a year. As a result, the relative contributions of all sources of air pollution in an area with a monitoring station are determined, together with the absolute contributions of single or groups of sources of pollution and the levels to which the emissions need to be reduced to meet the requirements of Directive 2008/50/ESt. The proposed methods are verified using data from measuring stations complying with that required by this Directive and are suitable for improving plans aimed at reducing air pollution as defined by the same document. This approach using data for a particular area revealed a total concentration of PM10 of 22.72 μg/m3, with the maximum permissible concentration of 12.33 μg/m3 this necessitates a reduction in concentration of the contributions from this selected group sources of 10.37 μg/m3. When these simple methods are used, further and more accurate apportionments of the source could be made using more complex mathematical modelling. However, this is only necessary in areas with many sources of pollution. Although these methods cannot compete with disperse and other types of modelling they may be useful in providing a basic overview of the situation in a particular area.","PeriodicalId":11931,"journal":{"name":"European journal of environmental sciences","volume":"7 1","pages":"27-34"},"PeriodicalIF":0.8,"publicationDate":"2017-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41617360","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Funneliformis mosseae (F) and Acaulospora laevis (A), on the growth of Phaseolus mungo subjected to salinity levels of 4, 8 and 12 dS m−1. Mycorrhizal fungi alone and in combination improved the growth of the plants at all the salinity levels over that of the untreated control plants. However, a combination of F. mosseae and A. laevis resulted in maximum root and shoot length, biomass, photosynthetic pigments, protein content, mycorrhization, nodulation, phosphatase activity, phosphorus uptake and yield at the 8 dS m−1 salinity level. Peroxidase activity and electrolyte leakage were minimum at the 8 dS m−1 salinity level due to improved water absorption as a result of the highest mycorrhization occurring at this level of salinity. Nitrogen and potassium uptake decreased with increase in salinity and highest uptake of these nutrient elements was recorded in the treatment with both mycorrhizal fungi at a salinity level of 4 dS m−1. The results of the present experiment indicate P. mungo inoculated with F. mosseae and A. laevis can be successfully cultivated of at salinity level of 8 dS m−1. Saline soils with an electrical conductivity of nearly 12 dS m−1 were not suitable for growing this legume.","PeriodicalId":11931,"journal":{"name":"European journal of environmental sciences","volume":"7 1","pages":"5-13"},"PeriodicalIF":0.8,"publicationDate":"2017-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42163766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
