Historický vývoj zooplanktonu Starolesnianskeho plesa (Vysoké Tatry, Slovensko) v kontextu globálních změn / Historical development of zooplankton of the Starolesnianske lake (the High Tatra Mountains, Slovakia) in the context of global changes

Blechová, Magdalena January 2016 (has links)
The aims of the thesis were to document the history of the Cladocera (Crustacea) community structure in the Starolesnianske Lake (the High Tatra Mountains, Slovakia) with regards to environmental changes (e. g., Medieval Warm Period, Little Ice Age, anthropogenic acidification, recovery from acidification), and to analyze in detail the development of zooplankton (Cladocera, Copepoda, Rotifera) during the peaking acidification and recovery from acidification (1978 - 2015). Based on results of both the approaches, the appropriateness of using historical data on zooplankton in Tatra lakes between 1909 - 1913 (Minkiewicz, 1914) as a reference condition for the evaluating biological recovery from acidification should have been assessed. The methods used were paleolimnological analyses of lake sediment (namely subfossil Cladocera), analysis of recent zooplankton, and analyses of lake water chemistry. It was found that in the historical record, relative abundances of Cladocera species significantly changed cca 150 years ago (at the end of the Little Ice Age and, in the main, in the period of anthropogenic acidification). The lake, though, has had a very stable species composition of Cladocera during the last cca 2,000 years, represented by four species: Alona quadrangularis, Alonella excisa, Ceriodaphnia...

Fytoplankton tatranských ples: faktory ovlivňující druhové složení a biomasu / Phytoplankton of the Tatra lakes: factors influencing taxonomic composition and biomass

Červenková, Lenka January 2010 (has links)
The aim of this diploma thesis was to describe species composition and biomass of phytoplankton in the Tatra Mountains lakes (Slovakia, Poland) and environmental factors influencing them. The surface layer of 89 lakes was sampled in September 2004. Flagellates from Chrysophyta, Dinophyta and Cryptophyta most frequently dominated the phytoplankton biomass. Lake in the same valley usually differed in their dominant taxonomic group as a result of different lake morphometry, catchment type and detailed geological structure. Based on the level of phytoplankton biovolume, the majority of lakes were ultraoligotrophic and oligotrophic, however, mesotrophic and even eutrophic conditions were recorded in some forest and meadow lakes. An allometric relationship between phytoplankton biomass and chlorophyll a was revealed. Specific chlorophyll content did not differ among taxonomic groups. Altogether 233 species were determined, the most diverse group were Chlorophyta. Species richness of lake was 3-46 and it was negatively correlated with altitude and positively correlated with lake area. The majority of species were rare both in term of biomass and number of lakes occupied by a particular species. Average local species biomass was positively correlated with regional distribution. The similarity of species...

Pastevectví na území národních parků ve Východních Tatrách. Kulturně-ekologické souvislosti v současnosti / Pastoralism in the East Tatras national parks. Cultural and ecological context in present

Bohušová, Ivana January 2016 (has links)
Shepherd's expansion into the Eastern Tatras valleys started latest in the 14th century. The peak of the pastoralism was Walachian colonization in the 16th century. Shephards usually used to drive out their herd (to pasture) to an altitude over 2000 meters above the sea level. The damage caused by grazing has grown to such proportions that pasturage was prohibited in some areas. After the establishment of the Tatra National Park the pastoralism in the High Tatras and Belianske Tatras in Slovakia was completely banned. In Poland shepherding was recovered in the form of cultural pasture, which is being regulated under strict conditions to prevent damage to the environment, after about 30 years long pause in the territory of Tatrzański Park Narodowy. The main objective of my thesis is to find out whether it would be possible to bring back the grazing to the territory of the Tatra National Park. If yes, then under what specific conditions, with what advantages or disadvantages, in its comprehensive perspective, not only natural but also socio-cultural. I took inspiration from the cultural pasture in Poland, and I was interested in the negatives of regulated grazing as well. I made my research in the form of semi-structured interviews with experts and with general public. The results of the empirical...

Diverzita zooplanktonu tatranských jezer v prostoru a čase / Diversity of zooplankton of Tatras lakes in space and time

Čablová, Radka January 2021 (has links)
This thesis is the first of its kind that evaluates the species composition, species richness and species abundance of zooplankton in littoral samples of 90 Tatras lakes (Western and High Tatras of Slovakia and Poland) collected in September 2004 in the context of environmental parameters of lakes and spatial relationships of individual lakes. The most frequently occurring species in the Tatras lakes in 2004 were also evaluated in terms of their occurrence in the lakes a century ago (Minkiewicz 1914, 1917 and Lityński 1913, 1917), during the period of acidification (Ertl & Vranovský 1964, Ertl et al. 1965, Hrbáček et al. 1974, Stuchlík et al. 1985) and during the period of recovery of the lakes from acidification (Hořická et al. 2006, Sacherová et al. 2006). Relationships between variables were analysed using Poisson regression, cluster analysis with multinomial regression, canonical correspondence analysis, Mantel tests and multiple negative binomial regression. Using analyses, lakes were divided into four clusters (A, B, C, D). Each cluster consisted of lakes with the same environmental and spatial factors and similar species composition. Thirteen zooplankton species (Acanthocyclops vernalis, Acroperus harpae, Alona affinis, Arctodiaptomus alpinus, Ceriodaphnia quadrangula, Cyclops abyssorum...

Kreativní centrum – Kopřivnice / Creative centre - Koprivnice

Křížová, Lucie Unknown Date (has links)
Right in the city center, there is a plot with old factory halls. These halls are fascinating and have great potential. But now, they are more of an obstacle. They form a barrier, they are in poor condition, and it robs the city of its values. In my diploma thesis entitled Creative Center in Kopřivnice, in addition to the design of the creative center, I will also deal with how to use the beauty and potential of these old halls, further, how to create beautiful and modernized buildings with a new value. I want to open the whole area, to create a place where people would like to meet and where various functions will be mixed- a place for fun, relaxation, culture, education or even just a shopping or walk. The work is very diverse - from the urban design of the entire plot, through the revitalization of old industrial halls and the layout of a new building, to the interior design of a new gallery.

Výroba zbraní pro Wehrmacht a armády spojenců Německa v českých zbrojovkách za Protektorátu Čechy a Morava v letech 1939-1945 / Production of Armament for Wehrmacht and German Allied Armies in the Protectorate of Bohemia and Moravia, 1939 -1945.

Pojikar, Pavel January 2011 (has links)
The Thesis with title " Armament production for Whermacht and the Army of Aliance in Protectorate of Bohemia and Moravia (1939 - 1945) is interested in detailed description of armament production within quality and quantity armoured of vehicles and infantry weapons made in war years 1939 - 1945 in Czech munition factories. Foreword part deals with Czech production efore Munich agrément,suitable conditions for militarization and empowerment German Army nor the use in industry either for strategy location. In following chapters the work describes main munition factories (Škoda Plzeň - Skoda Werke, ČKD Praha - BMM, Munition faktory Brno)and due to occupation our country,Czechoslovakia,maximal use of technical and human potenciál in Protectorate.The same it documents sale of spare weapons (cannons and munition) and presents German production,too. In other chapters it directs to confrontal of weapons,thein improvement,following development,army tanks, (mainly tank ŠKODA vz. 35, tank ŠKODA vz. 35,light tank LT vz. 38 and later fighter tank and offensive cannons from útočná ČKD Prague , Marder III, Hetzer, Grille), infantry weapons made in Brnopěchotní (Carabine Mauser K98 and gunmachine MG34, MG42, MG131). It mentios the biggest problem of German armament industry during War,that was critical shortage of raw...

Neužitečné věci / Useless Things

Maloušková, Drahomíra Unknown Date (has links)
Useless things. I normally use trash things like pattern in painting still life. My father suffers from obsessive compulsive disorder – accumulation of things. In addition to painting, I also work with objects themselves. My interest also closely related to how the concepts of the subject, object and artifact are appliing in contemporary art. There are the tradition of imitation fact, principle of ready-made, the issue of technical reproducibility and virtual reality of things in history of art. As a central theme of my thesis, I selected the part of bodywork Tatra 613, which carries all the testimony about ,,useless and hopeless "situation in which it is located. It is also an object monumental and visually very aesthetic. Yet it is not my intention to settle for the principle of redy-made. Asked about artwork as intermediaries art and its seemingly useless producing and reproducing, I want to try to create another such usless situation. That's why I make a cardboard copy (1: 1) of this object. I also make video with motive 3D copy of the same object. I like to create some voltage between that useless object and valuable art practice. I think, it does not just mean such futility when these objects will be viewed as an art.
