<abstract xmlns="http://www.w3.org/1999/xhtml"> The formation or activation of landslide movements in Podtatranska kotlina is quite common, as it is flysh and volcanic area. There is a high incidence of sandstones in this area. The sandstones crumble and weather, and this is the reason why the subsoil becomes unstable. The rainfall is accumulated, and there is a danger of soil sliding down. There was located groundwater level in the central part of the slope (in the height of 30 cm), and in some parts, the water accumulation occurred in the depression places on the landslide body. There were created small landslide lakes, where the water was held during the year. The slope was soaked and the erosion started to increase. The slope with its instability has pushed the construction of road that leads underneath the heel of the slope. Neglected and improper construction in areas of slope landslides has become a relatively common phenomenon. Stabilization measures are often made up only when real problem occurs. An anthropogenic activity usually starts this problem. This refers to deforestation, grassing or deformation of slope stability in the heel by improper construction. The landslide was not the first one in the area. In 1898, there was the first landslide, but it was not as intensive as this one. Retaining wall was the only one stabilization measure which was built in that time. It also had a drainage outfall. However, during the summer months in 2010, the stabilization measure was disrupted and cracked. This occurrence started after the slope separation and by the foremost pressure on the given wing wall. During our measurements, we found out that in that area, there was a loss of plant cover, erosion accrued and soil physical properties changed. Our aim is to show the seriousness of the situation and propose appropriate stabilizing measures.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"> The aim of this paper was to analyze and evaluate sediments of selected water reservoirs Počúvadlo, Malá Richňava, Veľká Richňava, Windšachta, in order to determine the concentrations of copper in the monitored water reservoirs in the Banská Štiavnica region. The analyses of the sediment samples were carried out by flow electrochemistry and atomic absorption spectrometry. In the study area, the samples were collected from 2001 to 2010; we found the following concentrations of copper in the range from 1.66 mg.kg-1 to 14.0 mg.kg-1 Cu of dry matter. The copper concentrations in the sediments were well below the risk limit according to “The Methodological Instruction of the Ministry of Environment of the Slovak Republic no. 549/98-2”. Based on the calculated dependency index, it is possible to assess the development of changes in the concentrations over the years as highly dynamic, and unsatisfactory for natural environment.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"> The paper is a part of the park reconstruction project. Following the historical information of a formal promenade existence in the park composition from the 19th century, there was a need to confirm this assumption. Non-invasive measuring with georadar X3M equipped with 500 MHz shielded antenna from Swedish company MALA was selected as a method. As much as 12 measurements were made, crossing the park in different directions- either parallel or perpendicular to the main axis of the park - as the promenade was parallel with the main axis. Afterwards, the measurement results were processed by Rad Explorer 1.41 and GroundVision 2 software. The visual interpretation of radargrams showed root crowns of trees, probable placement of the promenade and, of course, engineering infrastructure (water pipes); however, the exact identification of all elements has to be proven by invasive methods.</abstract>

PODPOVRCHOVÝ PRIESKUM HISTORICKÉHO PARKU V SANTOVKE / UNDERGROUND EXPLORATION OF HISTORICAL PARK IN SANTOVKA

<abstract xmlns="http://www.w3.org/1999/xhtml"> Land consolidation projects have reached the state where there is sufficient sample of projects with lots of valuable information in the Slovak Republic (planimetric and hypsographic measurements, updated maps of soil-ecological units, concepts of local territorial systems of ecological stability, plans for the general principles of functional organization of the territory, etc.). However, their longer-term utilization is questionable, because there is no central data archiving of the projects. Documents remain on a CD somewhere in the documentation of land offices in most cases. In worse cases, documentation might have been lent and later irretrievably lost. This paper describes concept for a new system that would provide a coherent overview, especially for the graphical outputs of land consolidation projects. It is called System OKTOPUS, and with its help we can analyze, process and archive the data generated in land consolidation projects and/or in other documentation. Spatial data are included into the catalog of topics and the topics are divided into registries in the OKTOPUS System. The presented model area is the catchment area of Žitava river, on which we illustrate the OKTOPUS System, including examples of possible use cases. The final aim of the OKTOPUS System is publishing data on the web using platform(s) that allow users sharing/editing the geographic data.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"> European mistletoe (Viscum album) is an evergreen, perennial, hemiparasitic shrub, which is able to infect more than 450 woody species. Besides mechanical pruning, a hyperparasitic fungus (Phaeobotryosphaeria visci) could be a successful candidate to develop an effective biocontrol agent against mistletoe. It was necessary to find antibiotics which make the isolation easier and do not effect mycelia growth negatively under strain. Furthermore, we wanted to define a medium for optimal growth under in vitro laboratory conditions. Three different media (potato-dextrose agar, modified oatmeal agar, ¼ PDA + V8 agar) and four antibiotics (kanamycin, ampicillin, rifampicin, nystatin) were tested. Oatmeal agar and potato-dextrose agar are optimal to maintain the fungal strains, the colony diameter was 9 cm on the 12th day. All tested antibiotics are useful, except nystatin.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"> The selected SCS-CN method is used worldwide and adapted to the conditions of Slovakia. GIS environment provides an opportunity to simulate changes in land use, and then to calculate the total volume of water from the river and peak water flow in the river bed of the stream. The simulation was done for two rainfall events, 72 mm and 42.6 mm, which were measured in precipitation station in Jelenec (a village situated next to the area of interest). The calculation was made for 4 possible scenarios - current land use, forest, arable land and grassland and pasture. Culmination discharge and time of outflow from rainfall 72 mm for current land use were calculated using the NRCS method. The calculation of water runoff volume showed that similar values were measured for the rainfall of 72 mm and rainfall 42.6 mm in case of AMC-III. The highest values of water runoff volume were marked in the case of arable land in all calculations, the lowest one for forest. Comparison of designed stream cross section and calculated culmination discharge allowed us to determine the point of outflow from the river bed of the Drevenica stream.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml"> The study focuses on appearance and development of villa gardens which were established in the interwar period in the territory of the Czechoslovak Republic. In the introduction I outlined the historical context, which - to a certain extent - contributed to the development of villa gardens. Furthermore, in the introduction you may find a basic range of the current research work in the field. A special focus is dedicated to archive material retrieval. The field research chapter provides basic information on historical gardens preservation. The facts retrieved from archives and the field research define function, composition and contents of villa gardens. Varied range of information serves as basic literature which will be further exploited while formulating methodology procedures which can be adopted in conservation and maintenance of villa gardens in the period of the First Republic.</abstract>
