Odonata in the urban landscape
Fiala, Bohumil ; Černý, Martin (advisor) ; Harabiš, Filip (referee)
Urbanization is currently one of the main causes of landscape destruction, endangerment of species and homogenization of natural communities. Dragonflies are an important part of freshwater ecosystems. Due to their amphibious life cycle, they are influenced by environmental factors both in a water and on a dry land. Despite the negative impact of urbanization on the environment, the urban landscape has the potential to host a great diversity of organisms, including dragonflies and damselflies. The best way to support local diversity of Odonata is by appropriate management of freshwater habitats, including promoting diversity of aquatic, litoral and riparian vegetation, preserving the original bottom and banks of both lotic and lentic waters and improving water quality in cities. The connectivity of individual localities in the landscape and the reduction of ecological traps are also important ways to ensure the stability of urban populations. Small artificial water reservoirs and well-preserved secondary habitats have the highest conservation potential in most cities. Dragonflies can also play the role of umbrella species for the protection of freshwater communities (not only) in urban areas.
Modification of a diesel generator for parallel operation with the grid
Černý, Martin ; Ctibor, Jiří (referee) ; Knobloch, Jan (advisor)
This works applies the idea of adjustment an engine-generator, so it is possible to connect an engine-generator, or other type of a generator, to the electricity. Consequently, the machine can transform the power supply without an outage. This work concerns the complex approach, provides the descriptions of particular parts, sensors and active components of a motor-generator and includes the explanation of their function. Further research is focused on designing and drawing a plan with a choice of a control unit for the whole system. Finally, the work deals with the complex implementation and testing the machine in real operation.
Uplatnění vybrané plodiny v rámci programu "fair trade"
Černý, Martin
This work deals with Fairtrade sugar trade, maps terms related to the Fair Trade organization and Fairtrade trade. It also deals with the growing of the sugar beet and sugar cane and compares its growing demands, describes differences between production of sugar from the sugar beet and sugar cane and the importace of both plants and sugar for Czech republic. The second part of the work is research mapping knowledges about fairtrade, related terms and respondents interest in the origin of sugar they consume.
Analýza druhového složení vegetace ve vinicích vybraných vinařských obcí
Černý, Martin
Diploma thesis of theme: Analysis of Species Composition of Vegetation in Vineyards of Selected Wine-Growing Villages deals with the evaluation of weed species composition in wine-growing villages Hlohovec, Moravský Žižkov, Sudoměřice and Horní Dunajovice. Observations were made in July 2018 and the composition of weed species was evaluated by using the phytocoenological surveys. Recorded data were statistically processed by DCA analysis, followed by RDA analysis and their output was ordination diagrams. 172 species were observed in all vineyards. In the vineyards of the wine-growing village Hlohovec were mainly species: Chenopodium hybridum, Artemisia absinthium, Consolida regalis. In the vineyards of the wine-growing village of Moravský Žižkov were mainly species: Plantago major, Festuca rubra, Carduus acanthoides, There were species in the vineyards of the wine-growing village of Sudoměřice: Festuca pratensis, Daucus carota, Picris hieracioides. In the vineyards of the village of Horní Dunajovice were mainly species: Trifolium repens, Hieracium pilosella, Cirsium arvense.
Marine Mammals as Apex Predators
Slavíčková, Tereza ; Černý, Martin (advisor) ; Storch, David (referee)
Amongst marine mammals there are many predators, however only four species can be considered truly apex predators. Polar bears, killer whales, leopard seals and sperm whales all dominate their environments, moreover, killer whales and sperm whales hold their position at the top of trophic relationships globally. Apart from being generally abundant and being large in relation to their closely related species, these four predators share very little. They differ in social structure, foraging ecology, life histories and levels of intraspecific cooperation. Very few studies focus on what characteristics makes each one of them such a dominant predator. Considering how abundant these species and their prey are, there is not enough research exploring predatory and non-predatory interactions with other large mammalian predators of our oceans. Our understanding of trophic relationships, large predators' influence on species hierarchy and ecosystem balance is poor. Considering the influence human population has on the oceans and large marine predators, more future research should be focused on exploring the complex interspecific relationships.
Apartment house
Černý, Martin ; Hrochová, Žaneta (referee) ; Sedláková, Markéta (advisor)
The subject of the bachelor's thesis is the design of an apartment building in Humpolec. It is an apartment building, which has four floors above ground and one underground floor. On the first floor part of the house is designed for administration. The building is built on a slightly sloping terrain and is free-standing. Main entrance with entrance to the collective garage is situated to the southwest, where the existing access road is. Nine different housing units are designed. The construction system is made of ground ceramic blocks. The ceilings are made of prestressed panels and the roof is single skin. The work contains project documentation of the actual implementation.
The law is the same for all but ignorance of law is no excuse
Černý, Martin ; Cvrček, František (advisor) ; Maršálek, Pavel (referee)
The law is the same for all but ignorance of law is no excuse. Abstract: This work discusses the comprehensibility and accessibility of law by the general public. Its goal is to analyse the barriers that make it difficult for the public to understand law. The instability and bad quality of statutes are identified as the key issues of law-making. The main reason for both of these problems is the motivation of politicians to present themselves as active legislators and gain publicity. The law publication is currently undergoing a transformation in the Czech Republic. This is due to the implementation of the e-Collection and e-Legislation. A great improvement will be achieved by the publication of consolidated texts. A personalized dissemination of legal information could be one of the future steps. The application of law by the Czech judiciary is of a very high standard but suffers from long proceedings. I confronted the theoretical conclusions with available research. I also tested selected government solutions. The Czech Republic is investing in digitalization, but the results are still unsatisfactory due to the poor quality of the services. In the last part of my work I suggested a solution based on the parallel between legal systems and software applications. My proposition is to divide law into three...
Genetic diversity of central European Cyclopsspecies
Krajíček, Martin ; Černý, Martin (advisor) ; Hudec, Igor (referee)
I studied the genetic diversity of central European Cyclops (Crustacea, Copepoda) species. The present thesis deals with all species of the genus Cyclops known from the Czech Republic (C. strenuus, C. vicinus, C. abyssorum, C.insignis, C. singularis and C. furcifer); the occurrence of C. singularis and C. heberti there is recorded herein for the first time. Other two species under study are C. ochridanus, an endemic species from the Ohrid lake, and an apparently new species of the genus Cyclops from the Retezat Mts. in Romania. Populations of Cyclops abyssorum from Romania, Slovakia and Switzerland were studied as well. The amplification of a part of the COI mitochondrial gene, using the universal arthropod primer (Folmer et al. 1994) or primers derived from it, was successful only in less than half of the populations under study. In contrast, amplification of a part of the 12S srRNA gene, using the primer of Machida et al. (2002), worked very well in all the populations. Cyclops abyssorum, a morphologically and ecologically variable species, showed very low between-population sequence polymorphism. The ecotypes "praealpinus", "divulsus" and "tatricus" seem to lack a species or subspecies status. They are likely to be, as Einsle (1980) supposed, morphological variations only. Populations of C....
