Význam remízků a jejich ekologických vlastností pro ptáky v intenzivně obhospodařované zemědělské krajině / The importance of woodlots and their ecological characteristics for birds in an intensively managed agricultural landscape

Rajmonová, Lenka January 2019 (has links)
Various types of woody vegetation are a key biodiversity refugee in intensively managed agricultural landscapes. However, the role of woodlots, representing an important type of such a vegetation, remains overlooked so far. Whereas the previous studies focused on the effect of their area, shape and isolation, consequences of variation in their habitat quality for biodiversity were not assessed up to now. This thesis is thus one of the first studies focusing on woodlots as a specific habitat for birds in agricultural landscape. My goals were: (I) to find out what is the bird community composition of woodlots in a Czech landscape, (II) to find out, what are the key habitat predictors of bird species richness and abundance in woodlots, (III) to describe differences in habitat preferences among various guilds and (IV) to formulate recommendations for conservational practice. I surveyed birds in 82 woodlots in an intensively managed landscape in Central Bohemia, Czechia, and measured variables describing woodlots' habitat quality together with woodlots' area, shape, isolation and types of surrounding land-use. I recorded numerous forest and non-forest bird species (57 in total), including some endangered farmland birds. The habitat variables showing significant relationships to bird community...

Magnetické stavy spinového ledu v umělých magneticky frustrovaných systémech / Magnetic spin ice states in artificial magnetic frustrated systems

Schánilec, Vojtěch January 2018 (has links)
Uměle vytvořené systémy spinového ledu jsou vhodným nástrojem pro zkoumání neobvyklých jevů, které se v přírodě dají jen těžko pozorovat. Speciálním případem umělého spinového ledu je kagome mřížka, která umožňuje zkoumat kolektivní chování spinů v látce. Tento systém má řadu předpovězených exotických magnetických fází, které zatím nebyly změřeny a prozkoumány v reálném prostoru. V rámci této práce se zabýváme úpravou kagome mřížky tak, aby mohla být využita ke zkoumání exotických stavů v reálném prostoru. Experimenty provedené na naší upravené mřížce ukazují, že jsme schopni detekovat nízko i vysoko energiové stavy, a tedy, že námi navržená úprava kagome mřížky je vhodná pro zkoumání exotických stavů v reálném prostoru.

Aplikace pro zpracování dat z oblasti genového inženýrství / Application for the Data Processing in the Area of Genome Engineering

Brychta, Jan January 2008 (has links)
This masters thesis has a few objectives. One of them is to acquaint with the problems of genome engineering, especially with fragmentation of DNA, the macromolecule DNA, the methods for purification and separation of the nucleic acids, the enzymes used for modification of these acids, amplification and get to know with cluster and gradient analysis as well. The next aim is to peruse the existed application and compare it to the layout of the proposed application, that is the third aim. The last one from the objectives is the implementation and the report how was the application tested by the real data. The results will be discussed as well as the possibilities of the further extension.

Drobní zemní savci podél přirozených a antropogenních krajinných bariér / Small terrestrial mammals along natural and anthropogenic landscape barriers

BOHDAL, Tomáš January 2011 (has links)
The dissertation summarises the result of the study of small terrestrial mammals (Eulipotyphla, Rodentia) along natural (watercourses) and anthropogenic (road, highway) landscape barriers. It points to an interesting phenomenon of road drainage ditches as a transitional migration environment, further it assesses the level of locomotion activity, the rate of structure of subpopulations and the frequency of crossing watercourses in the case of selected rodent species. It contributes with its results to solving problems concerning the effect of these landscape structures on the species diversity, ground mobility or genetic structure of small terrestrial mammals. ˙˙˙˙

Fragmentace a savčí predátoři v lesních habitatech: faktory ovlivňující jejich distribuci a výběr prostředí / Fragmentation and mammalian carnivores in forest habitats: variables which affect carnivores distribution and habitat choice

PAVLUVČÍK, Petr January 2010 (has links)
The human use of landscape causes fragmentation and loss of original habitats. Different species vary in their sensitivity to habitat loss. Especially carnivores can be more sensitive to decrease of their habitat because of lower abundance of their prey. On the other hand several opportunistic carnivores can profit in human modified habitats. This study was carried out in the České Budějovice basin, Czech Republic during the years 2008 and 2009 and the aim of this study was to determine carnivore{\crq}s habitat preferences in the fragmented landscape. During these two years were seven carnivore species monitored in forest patches by using scent stations. Records of this monitoring were compared with physiognomy of these patches and structure of surrounding landscape.

Nestacionarita konstrukce národu v současné Evropě: Časoprostorová diferenciace v podpoře a vlivu faktorů regionálního nacionalismu v Katalánsku / Nonstationarity of nation-construction in contemporary Europe: Time-space differentiation in support for and factors behind regional nationalism in Catalonia

Lepič, Martin January 2021 (has links)
Regional nationalism and consequent separatist tendencies have a significant impact on the territorial (dis)integration of many countries across the globe, and Europe is no exception. These processes contributed to changes in the traditional academic understanding of states as uniform, cohesive, and continuous political entities. Nevertheless, research on territorial and societal cohesion and continuity within regional nationalist movements has so far been neglected, even though this aspect seems to be key to the successful mobilization and goal achievement of separatist movements in heterogeneous democratic societies. This thesis aims to examine the limits of uniformity and continuity, that is, a time-space differentiation in political affiliations to secessionist regional nationalism in Catalonia, including the explanation of a time-space nonstationarity in the effects of factors behind the affiliations. Catalonia is an example of region with intense cultural and inclusive-assimilationist nationalism which proliferates within an ethno-culturally heterogeneous and segregated society. In the last decade, the region has shifted from a phase of everyday, "banal" nationalism to an explicit and dynamic nationalist mobilization, which has been brought about by (and further intensified) the deterioration...

Pokročilé nástroje pro měření výkonu / Advanced Tools for Performance Measurement

Smrček, Jaromír January 2008 (has links)
This thesis presents the I/O layer of Linux kernel and shows various tools for tuning and optimization of its performance. Many tools are presented and their usage and outputs are studied. The thesis then focuses on the means of combining such tools to create more applicable methodology of system analysis and monitoring. The practical part consists of applying SystemTap scripts for blktrace subsystem and creating a fragmentation monitoring tool with graphical output.

Efektivní správa paměti ve vícevláknových aplikacích / Effective Memory Management for Multi-Threaded Applications

Vašíček, Libor January 2008 (has links)
This thesis describes design and implementation of effective memory management for multi-threaded applications. At first, the virtual memory possibilities are described, which can be found in the latest operating systems, such as Microsoft Windows and Linux. Afterwards the most frequently used algorithms for memory management are explained. Consequently, their features are used properly for a new memory manager. Final design includes particular tools for application debugging and profiling. At the end of the thesis a series of tests and evaluation of achieved results were done.
