Investigating associations of saproxylic beetles with forest structure through the analysis of species composition and feeding guilds
KOZEL, Petr
The thesis contains studies focusing on various forest biotopes of Central Europe and saproxylic beetles as a model group for forest ecology research. In the review, current knowledge about the threats for forest biota, mainly saproxylic beetles are discussed in the context of species composition and trait-based approach. Various stages of succession in the patches of disturbed forests, their connectivity, the introduction non-native tree species, and the assessment of feeding guilds using stable isotopes are studied in the relation to saproxylic beetles in separate chapters.

Supporting grassland biodiversity through small-scale fallows
Fabšičová, Martina ; Frei, I. ; Jiroušek, M. ; Smetanová, S. ; Šipoš, Jan ; Trnka, F. ; Vymyslický, T. ; Winkler, J. ; Zdražílková, M.
The main goal of the methodology presented here is to propose a system of recommendations for applying fallow in nature conservation based on our experiments. Due to the independence of agricultural land outside specially protected areas with direct payments from the Ministry of Agriculture, it is currently important to apply the methodology, especially in large protected areas where the primary objective is to preserve natural and cultural heritage. Annual and perennial fallows, i.e. biotopes adapted toregular soil disturbance, offer suitable habitats for a number of now-threatened plant and animal species. This is a technically and economically easy solution, but it is challenging to select a suitable location to achieve maximum efficiency. Ploughing must not be used in species-rich grasslands which would lead to ruderalization and degradation of the native vegetation. Furthermore, it must not be carried out on land at risk of erosion. Linear grassland margins, which have been ploughed in the past, recently grassed fields, fallows, and field margins should be selected for fallow management. Nearby populations of invasive plant species can be a problem. Our recommendations for the use of fallow management relate primarily to land in lowland and upland areas with a lower soil nutrient supply.

Nástupnictví v rodinných podnicích
Slavíková, Lucie
This thesis focuses on the topic of succession in family firms. It focuses on the handover of the firm to the next generation and the measures that both, the transferor and the successor, have to take to make the handover successful. The topic of succession has been very topical in the last few years for family firms in the Czech Republic, which started to be established after 1989. The founders are now approaching retirement age and are dealing with who to pass their business on to, whether the descendants will build on their success and whether generational change will take place. The aim of this thesis is to define the main factors that influence the succession and to propose the optimal way of handing over the company to the next generation, based on the conducted expert research on this issue. In the practical part, selected family businesses with whom in-depth interviews are conducted are presented. On the basis of the evaluation of the obtained information, measures leading to the easiest possible succession transfer in a family business are proposed.

Stav a potenciál přirozené obnovy po kalamitě na revíru Polana, LS Jablunkov
Dyrčík, Vojtěch
The aim of the presented thesis was to evaluate the status and potential of natural regeneration in relation to the condition of surviving individuals of the parent stand after a bark beetle calamity. The locality of interest was the Polana forest district, located in the territory of the Jablunkov forest administration. Five representative stands were selected for the field survey, where after the death of the spruce stand component, there remained in the upper stage individuals of the parent stand, mostly beech (Fagus sylvatica L.). As the number of beech (Fagus sylvatica L.) individuals in the parent stand increased, so did the frequency of rejuvenation of this tree species. In places where there was less beech (Fagus sylvatica L.), spruce (Picea abies (L.) Karst) and white birch (Betula pendula Roth) became more prominent. The most abundant species in the parent stand were beech (Fagus sylvatica L.), sycamore (Acer pseudoplatanus L.) and larch (Larix decidua Mill). A relationship between the rejuvenation of beech (Fagus sylvatica L.) and the condition of the parent stand was also found in the area where the regeneration inventory was repeated. Here, the natural regeneration of Norway spruce (Picea abies (L.) Karst) was more pronounced,as well. In contrast to beech (Fagus sylvatica L.), its abundance in the regeneration decreased after two years.The areas of interest can be considered as restored to 94 % of the total area, of which 77 % was created by natural regeneration alone and 17 % by combined regeneration. In 6 % of the area, rejuvenation gaps need to be filled.

Přirozená obnova po odumřelém smrkovém porostu na Školním lesním podniku „Masarykův les“ Křtiny
Krásenský, Jiří
The aim of this thesis was to determine the state and potential of natural regeneration under dead spruce stands. The research was conducted at two locations in the vicinity of Brno within the University Forest Enterpise Masaryk Forest in Křtiny. A research plot was established at each location, consisting of three consecutive variants: stand, partial cut and clearcut. A network of circular sample plots was established in each variant to determine the state of natural regeneration. The investigation also included an analysis of seed fall in the stand and partial cut variants. It was found that the lowest mortality occurred under the dead spruce stand, compared to the other variants, and the largest number of seedlings were found there. The most common tree species that regenerated under the dry stand was spruce. The seed bank under the stand contained a more diverse range of seeds than under the partial cut.

Ecology of bryophytes in post mining sites
Fatková, Lucie ; Frouz, Jan (advisor) ; Mudrák, Ondřej (referee)
Mining sites offer a mosaic of spoil heaps of different age, with diverse substrate characteristics. Especially problematic for vegetation development can be toxic spoil heaps with substrate from the Tertiary rocks characterized by low pH values and a high content of heavy metals. Under such conditions, bryophytes survive amongst other groups of organisms. In the frame of this master thesis occurring bryophyte species were analysed on toxic, nontoxic and recultivated spoil heaps of different age. Soil parameters (pH, conductivity, content of heavy metals, organic matter and percentage carbon and nitrogen content) were tested and further environmental variables like coverage of vegetation layers were recorded to analyse the importance of these factors for bryophyte community composition on differently managed spoil heaps. In total 37 species of bryophytes were identified on spoil heaps in Sokolov. On old non-toxic spoil heaps bryophytes reached the highest diversity. Young non- toxic recultivated spoil heaps contained the lowest number of species although they were holding the highest coverage of bryophytes. Toxic spoil heaps bore less diversity than non- toxic spoil heaps. In early stages of succession short living life forms and short functional groups of bryophytes dominated. Successional...

Selected issues of international law of succession
Zahrada, Tomáš ; Pfeiffer, Magdalena (advisor) ; Zavadilová, Marta (referee)
Selected Issues of International Law of Succession The topic of this thesis is selected issues of international law of succession. These primarily target European succession law and its basic principles regulated by Regulation (EU) No 650/2012 of the European Parliament and the Council of 4 July 2012. Using the literature and case law of national and international courts, the author provides a brief insight into the basic principles contained in the individual provisions of the legislation and answers the question of to what extent they provide legal certainty and predictability to the testator and other persons when trying to plan an inheritance with an international element. In examining the shortcomings of the current European succession law in the context of legal certainty and predictability, the author compares the various expert opinions on the subject and adds his perspective. The thesis consists of three chapters, further divided into subchapters. In the first chapter, the author discusses the reasons for adopting legislation in the field of succession with an international element and then introduces the various sources of European succession law. In the second chapter, the author briefly describes the basic principles of European succession law, namely the uniform succession statute, the...

Monitoring of floodplain vegetation of the Hučina stream (Černý Kříž, Šumava) eight years after a hydric restoration
DEJMEK, David
The thesis is focused on the monitoring of the Hučina stream (Černý Kříž, Šumava) eight years after hydric restoration. The monitoring occurred in 14 permanent quadrats delineated in the open meadow part of the floodplain along three transects. In the studied quadrats, the groundwater level was measured, phytocenological relevés were recorded, and individual species' frequency and total coverage were determined. The results were compared with works by Lazárková (2012), Stachová (2014), Pechačová (2019), and Kratochvílová (2021) from previous years.
