Natural forest disturbances palaeoecology
Moravcová, Alice ; Pokorný, Petr (advisor) ; Novák, Jan (referee)
This Bc. thesis deals with the disturbances, which form an integral part of many ecosystems. The main foci are natural disturbances (in contrast to anthropogenic ones) of temperate and boreal forests. I deal with the causes of major disturbancy factors (fires, storms, disease and insect pathogens) and their impact on the ecosystem. I focused in detail on fires, because they represent an essential factor in the development of many ecosystems. Moreover, they can be studied in the past by using several tools of palaeoecological analysis: dendroecology, anthracology and pollen analysis combined with micro-charcoal particles quantification. The last part of the thesis discusses the role of disturbances in the secular succession of Holocene vegetation in Central Europe. It contains a chapter that describes a research strategy focused to the study of natural disturbances through paleoecological methods in a specific location (Rynholec, Central Bohemia). Key words disturbances, vegetation dynamics, fire dynamics, secular succession, palaeoecological methods

Environmental Factors In the Pathogenesis of Type 1 Diabetes Mellitus
Horáková, Lucie ; Novák, Jan (advisor)
Type 1 diabetes mellitus is autoimmune disease that is due to the interaction of environmental factors with genetically susceptible terrain. The increasing incidence of T1DM in western countries suggests the existence of environmental factors responsible for the increasing incidence of the disease. The identification of this putative factor is crucial for the development of strategies to prevent type 1 diabetes mellitus. By the analysis of literature, we identified the susceptible factors such as infection (coxsackie virus or cognate rubeola), early exposition to the cow's milk toxins etc. There exist even opposite theories such as hygiene hypothesis suggesting that the development of T1DM might be a result of the lack of protective environmental factor. Available data do not allow to detect causal relation between any of susceptible factors and the development of T1DM and do not allow to develop any strategy to prevent type 1 diabetes mellitus

Soul Care and the Problem of Education
Novák, Jan ; Pelcová, Naděžda (referee) ; Hogenová, Anna (advisor)
Care of the Soul and Problem of Education The Czech philosopher Jan Patočka shows two different modalities of soul concepts while thinking about Jan Amos Komenský's heritage for contemporary pedagogy. The close-set soul conceptus supposes simply recognizeable world, modern ideas of its controllability and scientific structure scheme. Education, which means care of the soul in three ways - care of the soul in the sense of cosmos order, in the sense of public and in the personal way, means (following close-set conceptus) formation, preparation and setting up the undone young being for life in the modern society. Reflexions of our contemporary situation find out, that modern situation appears as a crisis. This crisis demands a new approach to education, which could be found in the open-set soul concept. The open-set soul could be described as something incomplete, which is searching its fundamentals all the time. Another characteristic shows affinity of the soul for something superior or sense of own finality. Education in this way unveils itself like repeatedly reached humanity. This kind of education does not mean formation or setting up, this kind of education means revealing context of the world, society and finally own personality. Open-set mind should bring responsibility through this revealing. Every...

Natural restoration of mining sites: Vegetation succession and soil development: A case study from granodiorite quarries and dumps near the town Skuteč
Chuman, Tomáš ; Šefrna, Luděk (advisor) ; Novák, Jan (referee) ; Hradecký, Jan (referee)
Ir !ntroduction Environmenta| impaď caused by mining is considerab|e' The impact of mining on re|ief and landscape character is particularly substantial as could be documented on earth material transfer. While transfer of earth material caused by natural processes (erosion, sedimentation) is about 4 millions of cubic meters per year, anthropogenic transfer is close to 330 millions (Kukal' 2006) and material transfer due to mining represents the greatest proportion' lt is estimated that the surface minera| extraďion already covers 1% of the |and surface (Wa|ker & del Moral 2003). |n the czech Republic the extent of mining sites reached 0,8% in 2006 (Statistical Environmental Yearbook of the Czech Republic 2008). Miningcausesineversib|emodificationofre|ieíremovesvegetationandsoi|cover causing loss of biotopes. on the other hand mining creates new sites in the landscape e'g' water bodies, rock walls and screes. These sites are often unique and contrasting with the surrounding landscape and might harbor specific species afrer mine/quarry abandonment. Traditional approach to restoration was considered to be the restoration (reclamation) of production, whether agricultural or forestry, causing elimination of potential site diversity by morphology adjustment' topsoil application and tree planting or trefoil-grass...

Analysis of administrative management in conservation focusing on protected trees in Chrastava (Czech Republic) and its surroundings
Štochl, Štěpán ; Skalický, Milan (advisor) ; Novák, Jan (referee)
The first work theme was a description of an administrative procedure in the process of a protected trees approval. First it was necessary to set up legal viewpoints for the possibility to announce a protected tree. Next it is mentioned what is the reason to announce the protected tree and what is the procedure of a protected tree announcement proposal. It is described how to keep a record of the announced protected trees, how to mark them and what is the way to reach a care measures permission. The possible preservative care measures that are, except for cutting, the most important part of the old trees care are also explained . Next work theme is an analysis of the foreign system of a protected tree approval and announcement. From the historical point of view there is one of the widest base and the highest number of old trees at all in Great Britain and so it is possible to assume that the quality of tree preservative care is better than in our country. Speciffically the legislation of England, the law Tree Preservation Order, was chosen for these purposes. A comparison of both systems, Czech and English, was made. The systems do not differ much on a number of counts, for example in terms of tree value judging, a protected tree announcement proposal, a request and a care measures permission. The main difference is the 6 month long temporary tree preservation that can be used in the extreme cases as a protection against building companies and developers. Next part is devoted to the project of saving gene pool of protected trees. It describes the results and informs about the progress. The last part of the work was the documentation of protected trees in Chrastava and surrounding administrative region. 11 protected trees were evaluated, measured and photoed. The data acquired by this documentation will serve as completion of information about these trees in the Nature Conservation Central Register.
