Energetika larev tří druhů čeledi Bibionidae
Frouz, Jan ; Šustr, Vladimír ; Kalčík, Jiří
Food consumption, defecation, assimilation and production were studied in three species of bibionid larvae (.i.Bibio marci, B. pomonae, Penthetria holosericea./i.) feeding either on leaf litter or their own excrements. Assimilation efficiency of larvae feeding on leaf litter was in all species higher then assimilation efficiency of the same species feeding on their own excrements. Larvae reared on excrements also lost weight, which indicated that excrements were insufficient as an exclusive source of energy. In .i. B. marci, P. holosericea./i. the effect of temperature on assimilation efficiency was studied. In .i. P. holosericea./i. assimilation efficiency decreased with increasing temperature. This trend was not observed in .i. B. marci. B. marci./i. was fed on pure cellulose to test if cellulose can serve as the only source of energy. Mortality of larvae feeding on cellulose was significantly higher than of those feeding on leaf litter and did not differ from starving larvae.

Povrchová aktivita osmi běžných druhů chvostoskoků ve smrkových lesích a na pasekách po kůrovcové kalamitě v Národním parku Šumava, Česká republika
Brůhová, Jindřiška ; Rusek, Josef
Surface activity of eight common epigeic species of Collembola were studied in spruce forests, dead spruce forests and clearings in the Šumava National Park, South Bohemia, Czech Republic: .i.Lepidocyrtus lignorum, Leidocyrus cyaneus, Pogonognathellus longicornis, Tomocerus minutus, Tetracanthella stachi, Allacma fusca, Entomobrya nivalis, Dicyrtomina minuta./i.. Five pitfall traps were exposed at each of the 9 sites in the summer and autumn periods to study the impact of spruce forest die-off after bark beetle attack (dead forests) and on clearings. Material comprising 79435 specimens was evaluated in this study using the non-parametric Kruskal-Wallis test for comparing Collembola activity between the sites and seasons. Complete linkage (Euclidean distances) cluster analysis was used for comparing the collembolan activity in all nine sites.

Analysis of the decision-making factors in freight forwarder selection process
Šrámková, Eva ; Novák, Radek (advisor) ; Cempírek, Václav (referee) ; Průša, Bohumil (referee)
The thesis analyses the factors of customer decision-making process by choosing a freight forwarder in the Czech Republic market. While applying factors by other relevant research studies dealing with the decision-making process of customers in non-European countries, the research examines factors characteristic for the Czech customers. Questionnaires and in-depth interviews as research methods are applied. Within the research, a new service quality instrument TARRQUAL was developed. The TARRQUAL was proved on a survey including 250 customers of freight forwarder Kühne+Nagel Czech Republic. As service quality measurement, TARRQUAL is supposed to be applied particularly in logistics business field. The project aims at providing input for empirical research in the field of service quality in container shipping, which is lacking in the Central and East European countries.

Analysis of projects implemented within ROP Central Bohemia in the municipality Rožmitál pod Třemšínem the programming periods 2004-2006 and 2007-2013
Havlena, Luboš ; Říhová, Gabriela (advisor) ; Jílek, Petr (referee)
This thesis focuses on the regional development of the territory, with particular emphasis on the development of the village Czech Republic. It provides a comprehensive view of the theoretical basis of regional development and regional policy of the European Union, including in particular its application to the territory. The thesis analyzes programs that have been co-financed by the European Union under the regional operational programs in the programming periods 2004-006 and 2007-2013. Then it evaluates each programming period and summarizes their impact on community development. To complete the development of the work is completed by a SWOT analysis of the village, where they outlined the strengths and weaknesses of the territorial unit, including possible development opportunities and threats.

Between Prague and Vienna. Hermann Bahr and J.S. Machar and the spaces of (Central) European Modernism
Kostrbová, Lucie ; Brabec, Jiří (advisor) ; Fialová, Ivana (referee) ; Vojtěch, Daniel (referee)
This thesis deals with the relations between Czech and Viennese literary modernism during the 1890s, key amongst which were the contacts between Hermann Bahr and J. S. Machar. The contextual underpinnings, nature and significance of these relations are analysed in two monograph chapters. Chapter One focuses on the formation and transformation of Bahr's modernist programme as it moved between Berlin, Paris and Vienna, and an analysis is made of the programme keywords (Nervenkunst, Nervenromantik, Überwindung des Naturalismus, die Moderne, das gute Europäertum, Entdeckung der Provinz), which from the early 1890s found a response among Czech critics (e. g. F. Zákrejs, J. S. Machar and F. V. Krejčí). Bahr's conception of Viennese modernism and Austrian culture and the programme of the Die Zeit review were substantially influenced by Parisian experiences of the plurality of artistic production. Chapter Two follows developments in the work of J. S. Machar after he moved from Prague to Vienna in 1889. Machar's experience in Vienna is analysed in texts of various genres (lyric poetry, correspondence, autobiography, polemics and essay writing) and on the basis of his varying literary and intellectual contacts, while attention is paid in particular to his relationship with Jaroslav Vrchlický and T. G. Masaryk. A...

Sukcese hmyzenek (Protura) a vidličnatek (Diplura) na haldách chemické továrny
Rusek, Josef
Primary succession of Protura and Diplura was studied on deposits of a former chemical factory at Petrovice u Karviné, NE Moravia, Czech Republic, in 1978-1979, 1993 and in 2002-2004. Chemically loaded deposits were 15, 25 and 60 years old in 1979 and a primary succession without plant re-cultivation took place there. The succession was delayed on small humps and slopes where the deposited substrate was covered by terrestrial algae, lichens and mosses. Protura did not enter the primary succession before a moss cover occurred on the 15 years old heap and they were represented only by .i.Acerentulus traegardhi./i.. Three species of Protura were established in the 20 years old grass-covered stage as well as on the 49 years old heap. They occurred in low densities up to the 74 years old stage (and older), in which a proturan community of 4-6 species was established.

Vliv různých travních směsí na společenstva pancířníků (Acari: Oribatida) v iniciálních sukcesních stádiích během obnovy květnatých luk
Starý, Josef
Altogether 400 quantitative soil samples were taken from 8 stationary plots in the localities Výzkum and Čertoryje in the Bílé Karpaty Mts. during the years 1999-2002. The present study is based on material of 10563 oribatid specimens belonging to 62 oribatid species. The lowest species richness and mean abundance were recorded on the plot with agricultural management.The highest mean abundance was found on the old sub-xerothermic meadow in Čertoryje. The eurytopic species .i.Scheloribates laevigatus./i. and .i.Tectocepheus velatus./i. as well as the heliophilous .i.Punctoribates punctum./i. were eudominant in all studied plots. These eudominant species were complemented by the dominant and recedent eurytopic species .i.Microppia minus, Hemileius initialis, Achipteria coleoptrata./i. and .i.Medioppia subpectimata./i.. The rare xerophilous species .i.Lucoppia burrowsi./i. was found in the plots sowed by different grass mixtures and in the fallow.

Potravní zdroje bezobratlých v Ardovské jeskyni a v jeskyni Domica - předběžné výsledky
Nováková, Alena ; Elhottová, Dana ; Krištůfek, Václav ; Lukešová, Alena ; Hill, P. ; Kováč, L. ; Mock, A. ; Luptáčik, P.
The chemistry (organic matter content and pH) of different substrates from the Ardovská and Domica Caves in the Slovak Karst National Park (Slovakia) and the composition of their microbial communities were studied. Differences in organic matter content and microbial communities were found between the substrates from the Domica and Ardovská Caves. A broad spectrum of photoautotrophic microorganisms (algae and cyanobacteria) was found in different cave microhabitats (cave sediment, rotten wood, earthworms casts and isopods faeces), but no algae were detected in the fresh bat droppings and in the intestinal tract of the isopod .i.M. graniger./i.. Microfungi and bacterial colonies play the primary role in transforming bat guano into a food source for saprophagous and microphytophagous invertebrates.
