Water utilization in ZOO Brno
Hejsková Pekárková, Marie ; Zlámalová Gargošová, Helena (referee) ; Kotlík, Josef (advisor)
Master's thesis deals with water utilization in exposition of arctic wolf and canadian beaver in ZOO Brno. Theoretical part describes water utilization in ZOO and processes in water connected with nutrient enriching and uprising of water bloom. Practical part focuses on monitoring water quality in April and May 2012 and concept to solute water filtration in ponds.

Seasonal variation of the territorial behaviour of the European beaver (Castor fiber L.).
Kadlecová, Hana ; Horáček, Ivan (advisor) ; Červený, Jaroslav (referee)
The presented thesis deals with the temporal and spatial changes in activity of the European beaver (Castor fiber L.) during different seasons. Basic dataset was obtained by continuous telemetric monitoring of selected individuals in years 2008 and 2009 in two different geographical areas, namely in the Bohemian forest and in southern Moravia. The scope of the thesis was to record, evaluate and interpret the behavior of European beaver during the year. I focused myself especially on the beginning and end of activity in relation to incidence of sunrise and sunset, duration of stay in the field, changes in the size of actively-used area and time-duration and length of the movement. In cases where there were more active individuals monitored within the studied area, I also watched for their mutual interaction. In statistical analysis of gained data I also took into account the sex and age of the individuals. Beaver's behavior varies during the year. They are most active in spring and autumn, while in winter their activity decreases significantly. This observation is valid not only for the time duration and length of movement trajectories, but also for the size of actively-used area. The beginning of activity is strongly correlated with the sunset, while the end does not show any correlation with...

Bottleneck and selection effects on MHC genes variability in relic and newly formed Eurasian beaver populations
Náhlovský, Jan ; Munclinger, Pavel (advisor) ; Bryja, Josef (referee)
MHC glycoproteins are an essential part of adaptive immunity and may also play a role in mate choice. In addition, MHC genes are the most variable of all known genes. For these reasons, they have been intensively studied for several last decades. However, research is complicated due to extreme variability and frequent duplications. The Eurasian beaver seems to serve as an interesting model. It underwent a dramatic bottleneck culminating in the end of 19th century, when only about 1,200 individuals survived in several isolated relic populations. Thanks to numerous reintroductions, beavers of various origin meet in newly established populations. However, knowledge of beaver MHC was very limited. Only a single MHC gene has been investigated in a detail, and some relic populations were not sampled. Utilising additional relic populations and additional MHC locus, I verified a significant reduction of the variability of beaver MHC genes and also found signs of selection in the past. Then I sequenced MHC loci in two newly formed populations. I confirmed the ongoing selection by the disruption of cytonuclear equilibrium and the advantage of divergent alleles. We therefore can have a unique insight into the several periods of the history of beaver populations: In the past, MHC diversity was shaped by a...

Predictions of financial distress of a company through financial analysis methods
Mišík, Igor ; Strnad, Lucien (advisor) ; Schönfeld, Jaroslav (referee)
The subject of the processed work on theme analysis of the company in distress is a business Olšanské papírny a.s. which has entered bankruptcy proceeding on 2.19. 2009. The aim of the work was to determine whether the methods of financial analysis can predict the fall of business in the future. The work consists of a theoretical part, which is a description of the methods used in the practical part and includes definitions of business in distress and division of system of ratio indicators according to their properties as well. The second, practical part, briefly describes the company and analyzes the various methods of financial analysis applied to a particular company. It also includes a table of individual bankrupt models with probabilities that predict bankruptcy of a company and graphical inter-company comparison with sector through the Spider analysis.
