Chemical and physical parameters of surface waters of streams in the Novohradsko area.
BERNASOVÁ, Tereza
The content of the bachelor thesis was the comparasion of chemical-physical parameters of surface waters in Novohradsko. The data, which were used in the thesis, were taken in 2014. Individual sampling points were differed in their management practices and types of ecosystem. The monitored parameters are associated with eutrophication: conductivity, pH, KNK4,5, nitrates and phosphates. Based on the results we can claim that the sampling points of agroecosystems reached higher values of the selected parameters. The biggest differences were detected in conductivity. The values of conductivity were oscitalled from 51,8 mS cm-1 to 164,4 mS cm-1.

Chemical parameters of surface waters in selected model ecosystems of the cultural landscape.
STRNADOVÁ, Johana
The aim of this study was to determine and compare the concentration of chemical parameters in five streams in Novohradské hory. Individual sampling points were different with their types of ecosystem, management practices, vegetation composition of growth and subsoil. Monitored parameters in forest ecosystems were: conductivity, pH, sulfate and calcium. In agrosystems observed parameters: electrical conductivity, pH, calcium, chloride and nitrate. The collected data generated graphs for the years 2005 - 2010. Based on the results we can say that natural mixed forest resists concentrations of sulphates and prevents the acidification of surface water. In contrast with spruce monoculture where surface water has the lowest pH because the sprice forest captures haigher quantitty of sulphates. Chemistry of water in agroecosystems corresponds to the flow through the landscape, which is used for economic activity. This was most evident in the stream, which in the upper sampling point flows through spruce monoculture and conductivity there was only 65 ?S.cm-1. On the contrary conductivity was substantially higher 175 ?S.cm -1 in the lower sampling point. Conductivity value of stream flowing through wet meadows, was 191 ?S. cm1. The measurement results confirmed that the water reaches the higher conductivity in the managed landscape.

Sustainable management of forest ecosystems - indicators of biodiversity
HOŠKOVÁ, Jana
This bachelor thesis is devoted to the topic of biodiversity and indicators for sustainable production of forest ecosystems. The work is conceived as a literature review of the problems and tries to view the various topics, with the problems that are closely related. Attention is focused on the individual chapters in particular summary (search) basic knowledge related not only to the nature and persistence of forest ecosystem functions of forests in terms of their environmental stability and durability, especially the work was focused on the identification of the main methods for monitoring biodiversity in forest ecosystems. The main objective of this work is to compare conventional and natural regeneration of forest ecosystems, and on this issue was also seen in terms of soil organisms (invertebrates), which can be considered as indicators of changes in biodiversity in forest ecosystems.
