Vliv způsobu obhospodařování lučních ekosystémů na výskyt samců chřástala polního ve vybrané části NP a CHKO Šumava / The influence of management of meadows ecosystems on the occurrence of male of corncrake (Crex crex) in the selected part of the Šumava National Park and Protected Landscape Area

PEKSA, Martin January 2011 (has links)
The aim of this work was to monitor the occurrence of males of corncrake (Crex crex) in the western part of the Šumava National Park and Protected Landscape Area and to find out the effect of meadows ecosystems management on its occurrence. The method of night counting of singing males of corncrake with the help of method of point transect was practised. Male territorial vocalization audio record was used as well. The monitoring lasted for the nesting season of corncrake from 2008 to 2010. The average altitude of studied localities was 879.57 metres above sea-level. Seventy four localities were studied. Corncrake preferred ungrazed and unfertilized perennial grasslands harvested after 15th July. It also preferred temporarily and permanently waterlogged localities. The localities grazed by farm animals affected the occurrence of corncrake negatively. The decrease in number of males was observed from 2008 to 2010 on studied localities. The numbers were even 61,5 % lower. From the above mentioned data it can be concluded that the best management as regards the occurrence of corncrake is ungrazed and unfertilized perennial grassland with late time of harvesting in the case of not fitting into an agroenvironmental programme protecting the corncrake.

Laboratorní výzkum nabíjení prachových zrn / Laboratory Investigation of Dust Grain Charging

Beránek, Martin January 2015 (has links)
The present thesis is focused on study of dust grain charging. The experimental part covers interaction between dust grains and high-energy electrons and self-discharging of grains by both field electron emission and field ionization. The second part of the thesis describes construction and evaluation of a linear electrodynamic trap of the novel design. We have observed charging of small dust grains towards high positive electric potentials when bombarded by the high-energy electron beam. We have described an increase of the secondary electron- electron emission yield from negatively charged grains due to the surface field. Further, self-discharging characteristics for both positively and negatively charged grains were measured. The relationship between discharging rate and the rate of the flow of atoms leaving the grain surface due to diffusion was observed for positively charged grains. This suggests significantly lower surface field necessary for ionizing such atoms compared to the ionization of atoms of surrounding gas and compared to the typically published field ionization thresholds. Based on the design published in the master thesis, a linear quadrupole trap of novel design was constructed. Testing measurements confirmed functionality and expected characteristics of the trap. In addition, effects of...

Britská pěchota a proměny evropského válečnictví na přelomu 18. a 19. století / British Infantry and Transformations of European Warfare at the Turn of the 18th and 19th Century

Prouza, Petr January 2015 (has links)
(in English): The author's main focus was on development and causes of military art changes which British infantry has undergone, especially in the years 1775 - 1815. In author's work, given the magnitude and the topic specificity, the only focus was primarily on the study of official documents, which were used for British infantry training and to form a tactical doctrine. Work is divided into five chapters, which consist of an introductory part to the topic issue and analyse warfare factors in the 16th and 17th century that survived throughout the 18th and early 19th century. The second chapter was devoted into two main streams, including tactical ways of thinking related to the 18th century, which Great Britain army faced and socialised with. The second part of the chapter deals with causes and ways of how the first infantry introduces its training with a prescription of all-army presence. The third chapter, as the most comprehensive part of my thesis, analyses the main training document that the British infantry used since 1792. This was meant to be a turning point to the introductory of similar legislation in the Great Britain. The fourth chapter deals with firearms, which the British line infantry used to use throughout the periods of process analysis. The last fifth chapter analyses the...

Vliv prostředí na vnitrodruhové rozdíly ve změnách početnosti polních ptáků / Intraspecific variability in population trends of farmland birds: influence of habitat and altitude

Hanzelka, Jan January 2012 (has links)
Farmland bird populations in Europe have been in decline for a long time. Agricultural intensification and growing a large share of crops that provide suboptimal breeding habitat could be the main causes of the observed decline. To explore these possible drivers, I focused on population trends of farmland bird species in different habitats in the Czech Republic over the periods 1982-1990 and 1990-2010. Specifically, I focused on the variability in trends within each species in respect to the differences in landscape management between the lowlands and mid-altitude areas before and after 1990. The expected effect of intensive farming in the lowlands until 1990 was reflected by a strong decline in populations of Northern Lapwing and Yellowhammer. The influence of less intensive farming in mid-altitude areas causing moderate population decline was confirmed rather by shrubs and trees species than farmland specialists. After 1990, less intensive farming in the lowlands should reduce the decline, which may have occurred, but compelling comparison of population trends between the two time periods was not possible for most species due to the lack of data. On the contrary, more intensive population decline in mid-altitudes after 1990, which should be the response to arable land abandonment, was not...

Možnosti zjištění zatížení lesních ekosystémů těžkými kovy pomocí jejich obsahu v parazitech zaječí zvěře

Štefek, Karel January 2014 (has links)
In this thesis the concentrations of heavy metals have been statistically appraised on the basis of samples gained from small intestines of European hare - Lepus europaeus and from an endoparasite Trichuris leporis (found by a washing method). Tha appraisal has been performed by atomic absorption spectrometry -- AAS, electrothermal atomization - ETA-AAS (for Cd, Cr, Ni, Pb), and means of atomization in the flame FAAS (Cu, Mn, Zn). The pieces of offal of hare game have been obtained from a common hunting in the localities of the Czech Republic represented by the region of South Moravia, Moravian-Silesian, Olomouc, and the Highlands. The sample collecting has been conducted from 2008 to 2012. Statistically significant differences of heavy metals concentrations have been found out between the individual localities. In addition, an endoparasite as a possible bioindicator of heavy metals load on the forest environment has been evaluated differently. Furthermore, in endoparasites there have been detected an exceeding of the hygiene limits for food. Conclusion made on the basis of all statistical analysis performed in this study says that Trichuris leporis indicates heavy metals load on ecosystems by wider range of heavy metals than the small intestine and more, considerably in the higher concentrations. Thus, Trichuris leporis can be used as a sentinel organism for the indication of heavy metals in the forest environment, at least in an area of the European hare territory.
