Anabaena - Phenotypic and genotypic diversity of planktonic strains in fishponds and reservoirs of the Czech Republic
ZAPOMĚLOVÁ, Eliška
Morphological diversity of 61 Anabaena populations of 13 morphospecies was described under the field conditions of Czech fishponds and reservoirs. Polyphasic approach was then applied in classification of 45 clonal strains isolated from those populations. Detailed morphological analyses were performed and partial 16S rRNA gene sequences were obtained for 33 of the strains, and secondary metabolite production was evaluated in 20 strains. Plasticity of morphological characteristics under varied conditions of light, temperature, nitrogen and phosphorus was studied in selected strains, as well as their temperature and light growth requirements. The results were then discussed with respect to the delimitation of single Anabaena morphospecies. A new genus Sphaerospermum was defined for the morphospecies Anabaena kisseleviana, A. reniformis and Aphanizomenon aphanizomenoides, whose phenotypic and genotypic features differed considerably from all other Anabaena morphospecies. Unique information was provided on the occurrence and distribution of A. reniformis and Aph. aphanizomenoides in the Czech Republic.

Analysis of climatological time series for selected places in Europe in the years 1961-2010
Míka, Tomáš ; Helman, Karel (advisor) ; Bašta, Milan (referee)
This bachelor thesis preoccupied with the analysis climatological time series mesured at seven selected meterological stations located throughout the European continent. The underlying data for this analysis were obtained from publicly available European database of ECA&D. The analysis is focused on calculation of the basic charakteristic and decomposition of time series. The aim of this bachelor thesis is to examine development of the time series of average monthly temperatures and precipation in the period 1961 - 2010 for individual weather stations and these data analyzed to compare with each other and explore similiraties and differences in temperature and precipation from individual station, not only in term of time but also terms of space. This thesis is divided into two parts. The first part is theoretical and generally discribes statistical methods. The second key part (practical) is devoted data processing and analysis of the time series.

Application of the Universal USB Module LabJack
PŘIBYL, Vojtěch
This thesis describes applications of general-purpose USB module LabJackTM. This thesis acquaints with individual measuring modules by LabJackTM Company. It describes the selected modules LabJack U12TM and LabJack U3-HVTM at great length. This thesis contains selected themes acceptable for the application with modules LabJackTM and selection and implementation of sensors usable in selected themes. In this thesis is the signal way through measuring chain from sensor of physical quantity to final signal evaluation through the software eSimLab in detail described, propounded, in practice implemented and checked by measurements.

Analysis of water demand depending on the level of temperature and precipitation
Malý, Vítězslav ; Slavíková, Lenka (advisor) ; Petŕužela, Lubomír (referee)
The demand for water is a very specific variable determined by many factors. The thesis aims to explain how does weather condition influenced the overall character of water demand. Predictions of climate change shows that in terms of CR it can expect changes in total precipitation during the seasons, the increase in average temperatures and a change in the variability and intensity of extreme events. The analysis therefore focuses on clarifying the impact of the level of temperature and precipitation on water withdrawals from public water supply. Analysis used daily data on the collection of water from public water supply for each interested location and daily hydrological data on the level of average daily air temperature and daily rainfall.

Study of temperature and wetness climate of the sedge-grass littoral during the vegetation season
RANDLOVÁ, Monika
Work is focused on studying thermaly-hygric clime sedge overgrowth concerning to his produce parametres and cubic heterogeneity. In construed baccalaureate work i focused on relation of production above-ground biomass slim sedge (Carex acuta L.), with dampness and thermal clime. Slim sedge (Carex acuta L.) is dominant plant in flood part of damp grass fields. Work lie in destructive following overhead biomass along vegetative season. Highest performance live above-ground biomass was analysed in July 1820 g × m-2, but as compared to next takings to be almost constant, in August was analysed 1670 g ×m-2 and in September be signed growth of live above-ground biomass on 1789 g ×m-2. Dry matter overhead biomass decrease with toward the end of vegetative season. In July value of weight dry matter come to 801 g, in August 676,6g and in September were to be signed lowest value 530 g. Weight measured in September was considerably effected downstream that the persisted from second half of August. With those values relate and diminishing value of LAI that the reached values in July 2,44 m2/m2, in August 1,24 m2/m2 and in September 0,59 m2/m2. Work primary lie it measuring thermal and hygric values. Temperature and dampness differ in growth and above growth. Temperature in growth reached lower values than above growth with whereby bears measured higher values dampness in growth. Baccalaureate work was processed in terms of experimental intention agricultural faculty MSM 600*7*665806 ? permanent tenable management techniques of agricultural economy in foothills and mountain regions focused on making harmony between produce and non-produce use".
