Parasites in nutria (Myocastor coypus)
Urbanová, Beáta ; Langrová, Iva (advisor) ; Nechybová, Stanislava (referee)
The aim of this work was published data concerning parasites coypu (Myocastor coypus).
The first part describes the anatomy and the ethology of a coypu. Nutria is a relatively large rodent, native from South America. It lives near the water areas in small family groups which are lead by the old female. Its body is adapted to the life in water. Nutria is herbivores, which eats littoral and aquatic plants. It is a polyestric animal which gives birth to about six nidifugous pups. The nutria is the non-native species in the Czech Republic. The first import of nutrias was held in 1924 from Argentina. After that they escaped from the farms and due to they got into the wild.
The second part of this work characterizes parasites that have been diagnosed in nutrias. Protozoa diseases cause the coccidia and Toxoplasma. The coccidia are parasites of the genus Eimeria and belong to the most dangerous diseases for nutrias. The trematodes (Fasciola hepatica) also occur in nutrias and causing obturation and destruction of the liver. Anoplocephala sp., Hymenolepis octocornata and Rodentolepis avetjanae from tapeworms parasitize in nutria. Additionally nutrias serve as intermediate hosts of Echinococcus granulosus, Multiceps serialis and Taenia tenuicollis. The diseases, caused by parasitic nematodes from class Nematodes, are caused by parasites Trichinella spiralis, Trichuris myocastoris, the worms of genus Strongyloides (Strongyloides myopotami), and the worms from superfamily Trichostrongyloidae (Trichostrongylus retortaeformis, T. myocastoris). Among the most ectoparasitic diseases frequently belong the scabies (Myocoptes myocastori, Chirodiscoides caviae) and Demodex spp.

Slivanská, Jana ; Kocmánková Menšíková, Lucie (advisor) ; Boukalová, Kateřina (referee)
This thesis deals with participants of local development. The aim of the thesis was to find out activities of micro-region CHOPOS. This micro-region is an actor in local development and the aim of this thesis is to monitor its activities. The thesis is focused on finding out how local actors contribute to the development of the site in accordance with the principle of an endogenous approach to development.
The theoretical part defines terms related to the issue of regional development. The findings of a secondary analysis of projects micro-region CHOPOS shows that the highest total costs of the projects for the period 2001-2008 were in 2003 (7,903 419 CZK). Most projects implemented by LEADER for the period 2007-2013 and implemented by the municipality Postupice and Teplýšovice, both municipalities made two projects (Postupice 1,529,961 CZK and Teplýšovice 1,033,657 CZK). Teplýšovice realized the most of the projects for the period 2001-2008, a total of 21 (with a value of 6,857,826 CZK).
Evaluated data from semi-structured interviews with mayors of micro-region CHOPOS shows that all the mayors see nothing but benefits in membership in the micro-region. And all other municipalities consider as rather active. Actors considered the most successful project of lookout of Špulka. These interviews were also found reason for the subsequent entry into the union one of the municipalities. The reason was indecision of council.

Change trajectories of wetlands in the landscape of lowlands and uplands in the Czech Republic
Richter, Pavel ; Skaloš, Jan (advisor) ; Dagmar, Dagmar (referee)
Wetland habitats are of great multifunctional importance in landscape. In particular, they have the capacity to retain water during its surplus and then in the dry season to release the water. In this work the dynamics of change in wetlands coverage was analyzed, including the representation structure of different categories of wetlands over the past 180 years in the landscape of lowlands and uplands in the Czech Republic. The historical maps of Stable Cadastre, current orthophoto and current GIS layers of localization and classification of different types of land use/cover and landscape types were used as data sources. The area of wetlands has dramatically decreased from 5 762 hectares in the period 1825-1843 (more than 9.5 % of the area) to 54 hectares in 2014 (0.9 %). Based on the study of available documents three types of wetland habitats were classified: wet meadows, wet meadows with trees and swamps . Although, the most of the historic wetlands were constituted of wet meadows (89 %) these days the swamps (48 %) form the largest part of the wetlands. Half of the historic wetlands were transformed to arable land because of increasing production of agriculture. According to the evaluation of monitored changes by predictors it was found that more pressure on the degradation of wetlands was in the areas with more suitable climatic conditions for agriculture (e.g. The Danube basin, Moravia, soil types in the lowlands, Corn agricultural production area etc.). In these areas the swamps were formed as new wetlands in places of historical watercourses localization more significantly than elsewhere in monitored area. The aim of this work was also to describe the main driving forces and pressures that have influenced the changes in wetlands. The outcome of the paper can be used in landscape planning with regard to the protection and management of wetlands.

Genetic Diversity of Semi-captive Population of Western Derby Eland (Taurotragus derbianus derbianus) in Senegal and Phylogenetical Relationships between Western Derby Eland (T. d. derbianus) and Eastern Giant Eland (T. d. gigas)
Zemanová, Hana ; Lukešová, Daniela (advisor) ; Jarmila, Jarmila (referee)
Representatives of family Bovidae are subjects of many studies concerning with their phylogeny, phylogeography, time of divergence or genetic diversity. Taxonomy is solved by comparison of morphological characteristics or by genetic approaches, genetic diversity could be solved by pedigree or by genetic analyses too. Tragelaphinae number nine species of two genera, Tragelaphus sp. and Taurotragus sp. The antelopes of the genus Taurotragus (T. derbianus and T. oryx) belong to the largest antelopes of the world. Derby eland (Taurotragus derbianus) has two subspecies, Western Derby eland (T. d. derbianus) and Eastern Giant eland (T. d. gigas), which are distinguished on the basis of morphological characteristics. Western subspecies (T. d. derbianus) is classified as critically endangered. There lives the only population in Niokolo Koba National Park in Senegal, which numbers fewer than 200 individuals. For the conservation, the semi-captive breeding programme has been established in 2000. It was created by six founders (one male and five females), which are presumed to be non-related. The population within this programme had 95 living individuals in 2013, living in seven herds in Bandia and Fathala reserves in Senegal. The population is under breeding management, which efforts to minimize kinship of the individuals. Studbook was established for the Western Derby eland (T. d. derbianus) in 2008 and is published annually. It acts about small population with low number of founders and no gene flow, which is threatened by inbreeding and genetic drift. Genetic diversity of the population was evaluated by means of microsatellite markers and the results were compared with the results of pedigree analysis. Pedigree analysis showed the highest genetic diversity in the generation of founders (FOUNDERS). It decreased in the generation of founders' offspring (OFFSPRING 1; born in season 2007/2008), due to the fact, that the only male took part in the reproduction. And it increased again in the generation of offspring of founders' offspring (OFFSPRING 2; born in the season 2009/2010), because more individuals were included into the reproduction. Fifteen individuals and five polymorphic microsatellite loci (from the total number of 13 tested loci) were chosen for the genetic study. The parameters of genetic diversity (HE and HO, Ar and deviations from Hardy-Weinberg equilibrium, and FIS and FST) were evaluated. Not any deviations from Hardy-Weinberg equilibrium were found out. The results of genetic analysis confirmed the highest genetic diversity in the population of founders (Ar = 2.79; HE = 0.664; HO = 0.750; FIS = --0.154). In both generations of offspring values of allelic richness and observed and expected heterozygosity decreased (Ar = 2.15; HO = 0.580; HE = 0.586 in OFFSPRING 1 and Ar = 2.14; HO = 0.370; HE = 0.480 in OFFSPRING 2). Contrary to the results of pedigree analysis, there was not been observed any improvement in OFFSPRING 2. The resultant values of genetic diversity parameters were quite satisfactory, despite of the low number of founders and mating of related individuals.

The spatial final cut optimisation
Kašpar, Jan ; Marušák, Róbert (advisor) ; Lstibůrek, Milan (referee)
For more than 150 years, timber indicators have been used for forest harvest scheduling in the region of current Czech Republic. With social changes and increased importance of forest yields and functions, there has been significant changes in forest management during this time. The changes in ownership structure after 1989 are most problematic from a sustainability standpoint. Also, the timber indicators cannot consider forest age structure, which is not ideal because even small changes related to abiotic and biotic disturbances may inhibit forest planning efforts. These changes to forest ownership and structure combined with current timber indicators make it difficult to ensure sustainable harvest levels over long time horizons. Methods of operations research, such as mathematical programming and heuristic methods, provide alternatives to historical harvest scheduling methods because they can account for forest age structure and spatial relationships over long scheduling horizons.

Fišer, Michal ; Hůnová, Iva (advisor) ; Matějíček, Luboš (referee)
This diploma thesis is focused on a comprehensive assessment of ambient ozone concentrations in the Šumava Mts. Meteorological station Churáňov showed spring and summer maxima. The highest values were recorded between April and June each year. Second maximum appears in August. Minimal values were recorded during autumn and winter months, the lowest values appeared between November and January. Data from the 15-year period 1995 - 2009 were compared. The annual averaged concentration of ozone was 79,4 µg.m-3 . The highest AOT40F values within the entire measuring period were recorded in 2006 (34,9 ppm.h) and 2003 (32,9 ppm.h), the critical level for forest is 5 ppm.h. In this thesis the dependence of surface ozone at selected meteorological factors (temperature, rainfall, humidity, wind speed and solar radiation) and polution factors (NOx and NO2) such regression. The non-parametric Mann-Kendall test has been developed for detecting and estimating monotonic trends in the time series and applied in our study at annual values: mean, 98th percentile and median. Trend in the annual value ozone 98th percentile was determined as statistically significant at Churáňov site during the 1995-2009 period. Trends in the annual ozone mean and median were determinated as statistically not significant. The thesis...

Impacts of corruption and fiscal evasion on selected sectors of the economy
Rodonaia, Elizbar ; Šrédl, Karel (advisor) ; Kopecká, Lenka (referee)
Corruption is one of the most famous and also the most serious problems of the contemporary world. The aim of the processing of the dissertation is to create the actual characteristics of corruption and fiscal evasion, both from theoretical and practical point of view, specify their manifestations in economies of Georgia and Czech Republic in conditions of contemporary globalization, as well as to express the effects of corruption and fiscal evasion on selected sectors of the economy. The international organization Transparency International compared corruption in different countries based on the values of the Corruption Perception Index (CPI), which measures the degree of corruption perception from a subjective point of view. Every year the index captures the current view on corruption in the public sector and surveys used for the compilation include issues related to the misuse of public power for private benefit. The Czech Republic has 51 points and is on the 53th position in the rankings, right behind her at the 54th position ranked Slovakia with 50 points. This placement reflects very bad situation in the state administration, poor functioning of political parties and the lack of anti-corruption policy of the state. From the collected data and time series was concluded a conclusion about the high correlation and the correlated indicators of corruption CPI and GDP per capita in PPP. Although among the least corrupt countries in the world in 2014 ranks developed economies such as Denmark, New Zealand and Finland, less sophisticated Georgia was able to stay 50th position ahead of Czech Republic and Slovakia. It is due to the fact that with the advent of the Governments of President Saakashvili and Prime Minister Ivanishvili underwent a major reform of the state administration, including the security forces. This testifies to the fact that the underdevelopment of the economy is far from being the main factor for the elimination of corruption and fiscal evasion in a particular country. Reducing scope of tax evasions and departures of companies to tax havens are aims of the electronic records of sales and changes in the procurement system. Transparency of decisions on the allocation of public contracts should be solved and carry out an inspection utilization of public funds. Limitation of the influence of officials in the public service would undoubtedly help to eliminate small (petty) corruption. More than the total elimination of corruption endeavour currently states on its reduction or elimination of its consequences.

Possible solutions to the restoration of overmature forest stands in the Lány game enclosuregame-park
Ambrož, Robin ; Vacek, Stanislav (advisor) ; Igor, Igor (referee)
Possible solutions to the restoration of overmature forest stands in the Lány game enclosure -- this is a problem that generations of foresters in the Křivoklátsko region have been faced with. The restoration has often been postponed; as a result, there has been a remarkable increase in the number of such stands in the game enclosure. Currently, almost a third of the game enclosure is covered by stands, predominantly beech, older than 160 years, and the suggestions on how to restore these stands are by no means unified, not only within the framework of the relevant authorities, but also among the management of the Lány forestry administration. In the past, the disintegration of stands in the highest age class was dealt with by a massive planting of large-sized plants in the whole area of the game enclosure, which has brought and will continue to bring about a remarkable increase in the forest protection costs. The aim of this PhD thesis is to answer the questions concerning the restoration of the local beech stands and to propose a solution that would be efficient in the long term. The basic questions have been phrased as follows: In what condition are the extensive large-sized plant plantings? What is the number of overmature forest stands in the Lány game enclosure and what will their future development be? Are these stands still capable of producing a sufficient number of beech seeds to ensure successful natural regeneration? In what way should we restore these overmature forest stands? How should we protect them from the game damage? It was necessary to find some of the answers within the framework of intermediate scientific tasks; however, the finding of a conceptual solution to the restoration of the game enclosure remained the main goal of this work. To fulfil the goals of this thesis, it was necessary to perform the inventory of large-sized plant plots; it was found out that the total number of individuals planted in the Lány game enclosure until the end of 2011 was 28,994 at 840 plots. The plantings established in 2011 were surveyed as to their vitality and height increment between the years 2011 and 2014. In 2015, a sample was selected on which the condition of the root system was analysed according to the type of a container used for the raising of large-sized plants. It is evident from the results that despite considerable investment in fencing, the large-sized plant plantings are very often damaged by game and have to be repeatedly reinforced. The root system analysis revealed that a significant number of individuals show serious root system deformations. Consequently, the optimization of large-sized plant planting was proposed. The condition of the beech stands at PRP was ascertained with the aid of the FieldMap technology; the stand development prediction was carried out by the growth simulator SIBYLA. The verification of the fertility of the overmature beech stands took place at smaller plots demarcated within PRP. The results show that the occurrence of game eliminates natural regeneration in these stands; thus, it is necessary to find a way which will not be only efficient, but also economical. The fertility verification proved that despite their advanced age, the beech stands preserve their ability to produce seed material, which could be used for regeneration under a shelterwood. Finally, a model regeneration block presenting two possible reproduction methods (with maximum utilization of natural regeneration and accelerated one) was designed on the basis of both the differentiation of the game enclosure and the localization of stands with the highest degree of regeneration urgency.

ICT support for regional development
Očenášek, Vladimír ; Havlíček, Zdeněk (advisor) ; Vostrovský, Václav (referee)
There are many of different rankings in the world, which relate to information and communications technology. For example, United Nations e-Government survey evaluates expansion of e-government administration in 193 countries in the world every two years and publishes worldwide ranking of EGDI (e-government development index). Since 2003 web portals of the capitals of the largest countries in the world are evaluated evaluated by - Digital Governance in Municipalities Worldwide (Holzer et al., 2014) every two years. This rating is organized by the "The E-Governance Institute" which is part of Rutgers University Newark. Prague (15 in) was included for the first time in 2007. Prague was ranked in excellent 2nd place in 2009, in the period 2011 - 2012 was in 4th place and in the period 2013 - 2014, Prague ranked 10th. Our methods of evaluation are based on methods of Digital Governance in Municipalities Worldwide, which is focused on regional web portals. We evaluated 6 regional web portals using 40 parameters in the area privacy, usability, content, services, citizen and social engagement. For instance, we evaluated if web portal provides: online publications, multilingual access, GIS, calendar of events, searchable database of articles, accommodation reservation etc. For evaluation of regional web portals, we chose two regional touristic headquarters (Centrála cestovního ruchu -- Jižní Morava (www.ccrjm.cz), Jihočeská centrála cestovního ruchu www.jccr.cz)), one regional touristic web (Posázaví - vítejte v turistickém regionu kolem řeky Sázavy (www.posazavi.com)), two Austrian web portals, which represents cross-border cooperation between Austria and Czech republic (Urlaub am Bauerhof -- dovolená na selském statku (www.agroturistika-v-rakousku.cz), Rakousko -- přijeďte a ožijete (www.austria.info/cz)) and official touristic web portal of Switzerland (Officielle Website von Schweiz Tourismus (www.mojesvycarsko.com)). As it turned out during our model usage, which took into account five important areas, level of regional web portals significantly differ. Some criteria are fulfilled across the all sites, but some of them are partly or completely missing. Individual solutions therefore often prefer different criteria, thus providing different perspectives on the region and its issues. If all criteria were met, the informational content and thus even usefulness of the individual portals would rise. Theoretically, this would lead to a "content compatibility" of individual solutions, which would ultimately bring profit to users and consequently the visitors of their respective regions.

Selected factors affecting the performance of racehorses
Jirásková, Petra ; Vostrý, Luboš (advisor) ; Karel, Karel (referee)
The aim of this thesis is the selection of most significant factors influencing the performance of racehorses and a subsequent analysis of selected factors in terms of influence on the performance of racehorses in the Czech Republic. Furthermore, the scientific hypothesis was that the obtained databases would allow for an exact analysis of the influence concerning selected factors (gender, age, season of birth and others) on the performance of racehorses in the Czech Republic
The horses´ performance depends on a larger number of factors, which can be divided into two groups. The first group is the internal factors (genetic preconditions, build, constitution, temperament and character) and the second group is external factors, i.e. factors influenced by the environment and independent of a horse. The conditions of the environment along with the horses´genotype influence horses´performace the most.
There is a wide range of external factors, e.g. season in which the horse was born, weight at birth, rearing of a foal, preventative health care, nutrition, moving regime, training, conditions of a particular race, the impact of age and gender.
The aim of this thesis was to evaluate the influence of selected factors on the performance. The general handicap has been used as the basic indicator of performance in individual horses, which is the performance evaluation of a horse in races in a particular year. The final database has been created in Excel, in which some calculations and graphs have been carried out as well. The very statistical processing has been done in the R program.
The influence of the birth season, gender and age on the horses´ performance has been gradually evaluated. It has been found that in two-year horses the birth period significantly influences the age when starting races for the first time (i.e. the later the horses were born, the earlier they were able to start racing). Moreover, a connection between the amount of prize money and the gender in two-year horses has been found, with mares reaching higher prize money. A lower number of days from the birth to the first start in a race has been found in mares. An interesting connection has been found between the age of the first start and the general handicap rate (participating in the first race at the age of two had a positive influence on the handicap rate at the age of three.)
