Effectiveness of protective measures against spruce bark beetle (\kur{Ips typographus} (L.)) at selected localities of LZ Boubín
 VAČKÁŘOVÁ, Tereza
The efficiency of various protective measures against the Spruce bark beetle (pheromone-baited traps, trap trees, poisoned traps - tripods.) and the impact of insecticide-treated trap trees on non-target organisms were studied in weekly periods in areas in the altitude of 1000m above sea level. Tree traps proved to be of much higher effectivity with an average of 3307 caught spruce bark beetles in comparison with pheromone-baited traps with only 457 beetles within the same period. Poisoned traps ? tripods baited with pheromone (FeSex Typo, producer ? Karel Ubik, CR) were more effective than pheromone traps and the average number of caught beetles was 1226. Among non-target insects caught in these traps were 61 species included 7 orders. The most common species was Thanasimus formicarius.

Issues of specific disorders of children at an elementary school in the České Budějovice
 VAČKÁŘOVÁ, Tereza
The Thesis studies the issue of specific learning disorders of pupils attending the first grade of primary schools. It is divided into two parts. The theoretical part describes the issue and the theory of specific learning disorders, such as dyslexia, dysgraphia and dysortographia. The Thesis aims especially to diagnose the specific learining disorders and the possibilities of reeducation and compensation of such disorders. The second part of the Thesis is practical. A reservoir of themes and materials was made for teachers to help to work with the diagnosed pupils. The goal of the Thesis was to help the teachers to improve the education of children with such specific learning disorders in the first grade of primary schools.

Relationship between \kur{Ips typographus} outbreak and Norway spruce ecosystem status in the Černá hora Mt. and Smrčina Mt. (Šumava National Park)
 VAČKÁŘOVÁ, Tereza
The aim of the thesis was to find out whether there is a relation between spruce-bark beetle infestation and health condition of spruce stands. The field work was conducted in Šumava National Park on two research plots ? Černá Hora and Smrčina. In order to determine the health condition of spruce stands the methodology according to Cudlín et al. (2001) was used. The emphasis was put mainly on monitoring the percentage of individual parts of tree crowns, total defoliation, defoliation of primary structure and percentage of secondary shoots. According to the parameters the rate of crown structure transformation was identified and the trees were classified into four stress categories. All the monitored research plots, founded in spring 2009, with an exception of plot ?B? in Černá hora, were infested with a spruce-bark beetle. Only a single tree infested in 2009 was identified in plot ?C?. The methodology according to Jakuš et al. (2009 and 2010) was used to periodically monitor spruce-bark beetle invasion and individual reaction phases of the spruce stands. Furthermore, according to the data obtained a layer of tree occurrence in various stages of bark beetle infestation was constructed in GIS platform using ArcView 9.3 programme. It enabled us to determine the degree into which the bark beetle infestation and consequent colonization of surrounding trees is dependent upon the trees´ mutual position and their crown conditions. A hypothesis that a spruce-bark beetle prefers trees with a more transformed crown structure (Moravec at al. 2002) was proved only on the plots in Smrčina. The thesis should contribute to the study of mutual dependence between bark beetle infestation and spruce stands health condition as well as to their development in reaction to such infestation.
