Evolution of the genus Malus with a particular reference to old and local cultivars
Polcar, Václav ; Urfus, Tomáš (advisor) ; Macková, Lenka (referee)
The following work deals with the genus Malus in terms of the significant diversity that this genus represents. It summarizes a basic knowledge about the taxonomic position and world centers of the genus evolution. Part of the thesis also discussed reproductive mechanisms as a source of the genus diversity. The thesis then focuses on the species Malus domestica, its evolution and the hybrid origin. In this context, old varieties of apple trees, their significance and pomologically important regions of the Czech Republic are presented. An integral part of this work is also devoted to the protection of old varieties, its limits and possibilities. The protection of old varieties also encompasses the extensive orchard as an important agroecosystem. Finally, different Czech regions are compared with respect to the quantity of reported old varieties.
Reconstruction of the fishpond system of Dymokury region
Kupka, Jiří
The article presents the results of the research on the historical cultural landscape in the administrative district of the Poděbrady Region carried out within the NAKI II project Practical Approaches to the Territorial Protection of Historical Cultural Landscapes. The research included the definition of units and units of historical cultural landscape and then a detailed analysis of the partially relict landscape of the former fishpond system of Dymokury Region. A partial output of the project was a map reconstruction of the fishponds and dykes to the state of 1713, from which the description of the ponds on the estate survived, presented in the form of an interactive map. The text presents the sources used, among which the archival maps stand out, especially the first military mapping, confronted with cadastral maps, aerial photographs and a digital relief model. On the basis of the analysis, 91 fishpond sites were identified in the study area, which were entered into the map and described and documented in detail. Thirty of them have been preserved to date, the rest of the water bodies have disappeared. Several larger ponds have survived on the Štítarský Brook, on the Smíchovský Brook and on the Záhornický Brook. Some of the fishponds have remained wet meadows, others have disappeared completely, but they are visible in the terrain, including the dykes that are still prominent today. The results of the analyses show that even a seemingly ordinary and uninteresting agricultural field landscape has a number of historical landscape structures, moreover with historically proven potential for water retention in the landscape.
Methodology of the Principles of Rehabilitation of Cultural Heritage Buildings
Balík L. ; Nedvědová K. ; Šimůnek I. ; Kudrnáčová L. ; Bolom-Kotari S.
The aim of the presented methodology is to summarize the rehabilitation principles that can be applied in the context of the repair of historic buildings. The methodology defines the fundamental influences that affect the approach to rehabilitation and also specifies the individual steps that are part of the actual implementation. Attention is paid to three basic areas of rehabilitation measures. These are addressing moisture and related problems, modifying the indoor microclimate, and restoring or strengthening the structural function of the building. Concerning conservation aspects, the principles presented are directed predominantly towards conserving and prolonging the life of the existing structural elements, taking into account future use and operation. The preservation of the original forms and functions of the individual structures is pursued as far as possible. The target group of users of this methodology is conservation officers, designers, owners, and managers of historic buildings. The methodology provides these users with the basic information for initiating the restoration of monuments.

Appropriate restoration practices to preserve traces of stone working. The use of close-range photogrammetry to evaluate the suitability of restoration procedures
Cihla, Michal ; Frommeltová, E. ; Hodač, J. ; Kovářová, K. ; Pavelka, K. ; Panáček, M. ; Valach, Jaroslav
This preservation procedure is the result of the research project entitled „Building stone surface topography and its application in the field of stone features restoration“ No.DG20P02OVV021, supported by the Ministry of Culture of the Czech Republic. The aim of the preservation procedure was to verify the suitability and applicability of precise measuring methods in order to assess the degree of restoration intervention in the area of traces of stone surface working. The method of close-range photogrammetry was chosen as a tool to evaluate the changes in the topography of stone surfaces bearing traces of working.
Methodics of using UAV technology for documentation of interiors & exteriors of historical monuments
Škobrtal, Milan ; Škobrtal Zlámalová, Aneta ; Buršík, Dalibor ; Čadilová, Michaela ; Krátký, Vít ; Meiser, Tomáš ; Petráček, Pavel
Methodics deals with process of documentation of exteriors of historical objects by UAV, including adequate legislative. But the main issue is documentation of interiors of arthistorical value by drones - through our unique safe documentation method. Methods accompanies case studies, included are general informations about drones and digitalization of historical mouments.

Conservation genetics of Galápagos mockingbirds: from immune genes to genomes
VLČEK, Jakub
In this thesis I have dealt with the population genetic processes of mockingbirds in the Galápagos Islands ( Mimus ) in relation to the limited island area, from the perspective of two types of immune genes and the genome-wide approach. The thesis starts with an introduction to population genetic concepts relevant to conservation genetics followed by description of immune genes: the major histocompatibility complex (MHC) and the Toll-like receptors (TLR). In the final part of the introduction, I address how genetic drift, selection and inbreeding shape genome-wide genetic patterns in small populations. The introduction is followed by four chapters, beginning with an examination of MHCII polymorphism in populations of mockingbirds in the Galápagos Islands. The study of the relationship between MHCII and the abundance of ectoparasites is the content of the second chapter. The third chapter shows how polymorphism of TLRs is shaped by interaction of genetic drift and natural selection. The last chapter deals with the effects of limited island size on inbreeding and genetic load, supported by inferences of the past demography of mockingbirds. The thesis concludes with a summary of the results and their potential implications in the field of conservation genetics.
Restoration, conservation and technological research as infrastructures of art history - and vice versa
Klípa, Jan ; Dienstbier, Jan

Methodology of Research, Revision and Passporting of Historical Library Collections
Šípek, Richard ; Mašek, Petr ; Hájek, Pavel ; Paličková, Tereza
The aim of the methodology is to present a clear synthetic guide and tool for the care of the historical book collection, its analysis in terms of content, chronology and provenance and its synthesizing evaluation in the form of a study. In addition to a comprehensive secondary bibliography on the issue of the historical book collection in the broadest sense and an overview of current legislation, it also contains a clear guide to the global treatment of the historical book collection according to its specific type, as well as recommendations for its long-term management and care. The methodology also includes advice on the selection of books for conservation and restoration and on ensuring appropriate storage conditions for the historic book collection.

Stanovení in vitro stravitelnosti organické hmoty kukuřičné siláže pepsin-celulázovou metodou
FOUS, Dominik
Silage, and especially maize silage, is the most abundant roughage both in the Czech Republic and in Europe. Silage compensates for a large part of the energy needed for the proper performance of animals. Stable efficiency and its increase can be ensured only by a constant and balanced composition of the feed ration throughout the year. Due to the importance of preparing quality feed, additives are often used. It is possible to add homofermentative bacteria to the ensiled mass with silage additives to rapidly lower the pH of the silage, or to add heterofermentative bacteria which improve aerobic stability in the silage, it is also possible to combine these bacteria or use other silage additives.
