Hodnocení welfare v chovu dojnic
Sovadinová, Simona
Animal welfare enhancement requires specific problems being reliably identified and corrective actions being defined afterwards. This diploma thesis evaluates the level of animal welfare on Czech farms with dairy and dual purpose cattle. The thesis uses the European project Welfare Quality®, which is a tool for a comprehensive assessment of livestock living conditions. WQ® gives the farms one of four final marks – excellent, enhanced, acceptable, and not classified. Most farms in this research were marked as acceptable. The organic farm received the best rating of all farms. Barns were most deprived of animal feeding, while animal housings were rated well. This research considers welfare as a multidimensional complex and also assesses specific aspects of dairy farming.

The degree of preparedness of the population for emergency survival
ŠAFROVÁ, Veronika
Awareness and readiness of people during emergency survival is a issue, which is not as easy to fix as it can seem on a first sight. Lifestyle and the ability of people to get their food resources is very different then it was before year 1989. As the society grows in a global and modern way, the level of independence is decreasing. All services, products and foods are within our arm's reach. We can state, that we live in a time of affluence - for now. This began to change rapidly two years ago, when the pandemic started or the corona virus as we know it. Many households have realized, that during quarantine they are dependent on their friends and family, because without shopping food, they wouldn't endure longer than 10 to 14 days. The corona virus epidemic wasn't the only test during the last two years that a lot of people had to go through. Another catastrophes were large floods, recent tornado in Moravia or ongoing safety threat in Ukraine. Another ongoing catastrophe is large wild fire in Bohemian Switzerland. This wild fire is a threat to properties, health and life to people and animals, but also protection of national park Bohemian Switzerland. This rapid downhill during last few months is a clear indicator, that the situation on our continent is shifting. Therefore population should slowly return to a partial independence, because if someone wouldn't do this in time, they might pay the highest price in the future. The issue of awareness and readiness of population for emergency survival based on author's research is very low. New generation is dealing with completely different habits, than our grand parents and great grand parents. Therefore author decided to do her own research and it confirmed her assumption. Result of the research confirmed, that actual readiness of population for emergency survival in crisis situations or catastrophes is truly very low. Author of these results got her answers based on her own research through electronic questionnaire. 555 households answered this questionnaire and 1188 individuals showed their interest. Another results of this test is, that if we compare our generation or generation of our parents, results are almost zero. Although results confirmed, that there is a huge difference in generation of our grand parents. Awareness of population in general across generations is on better level, however readiness is low as many people and households won't admit any catastrophes. Even though last few events show something else. Author decided to choose a questionnaire survey and based on these results do an examination and assessment of the level of readiness of the population for emergency survival. As another goal of the thesis the author processed basic characteristics of emergency survival of individuals or households. This characteristic can partially help novices to get prepared for upcoming situations. In foreign countries they use words as prepper or survival, which describes someone who is getting ready for extraordinary events or crisis situations. This basic characteristic can help people to gain knowledge and increase protection. This knowledge can also increase their safety. Because most of household consist from more than one individual, it's important to learn again how to safely take care of their own and their close ones. We mustn't depend on others or on the country to take care of us. It is needed to partially get back to our roots, knowledge and skills from our ancestors. We never know when we can benefit from these experiences or when they can even safe our lives. Result of this thesis is to lead respondents to change their way of thinking about this issue of emergency survival. Goal wasn't to scare or convince respondents, however to point on certain situations that could happen, so that they can prepare better.

Traditional versus modern way of children education - their relationship to old age and its impacts on society
DOBALOVÁ, Iveta
This bachelor thesis deals with the differences between traditional and modern way of children education and their relationship to old age an its impacts on society. In the theoretical part of my thesis I divote the traditional intergenerational cohabitation and todays modern family, where seniors are no longer part of close family, but (it they are self-sufficient) they live alone or in some sanitary facilities. This thesis deals with respect for seniors, intergenerational solidarity and behaviour of children to seniors. The practical part of my bachelor thesis includes usearch based on questionnaire, that focused on opinions of seniors and parents on this problematics.

Vliv metazachloru a jeho metabolitu metazachloru OA na raná vývojová stádia raka mramorovaného
ZÁVORKA, Milan
Metazachlor is a selective herbicide used for controlling monocotyledonous and dicotyledonous weeds in oilseed rape and other cruciferous plants. It is mainly used as a pre-emergence herbicide. Metazachlor OA is one of the major degradation products of metazachlor. The aim of this study was to evaluate the effect of metazachlor and its major metabolite metazachlor OA on the early live stages of marbled crayfish (Procambarus virginalis). The effect of metazachlor and metazachlor OA was evaluated on the basis of behaviour, growth, biomarker of oxidative stress, antioxidant biomarkers, ontogenetic development and occurrence of morphological anomalies. The toxicity test was performed at five concentrations, two concentrations of metazachlor (3.2 micrograms/l and 22 micrograms/l) and two concentrations of metazachlor OA (3.2 micrograms/l and 22 micrograms/l) and one control (C). The test exposure was 40 days under defined laboratory conditions. The exposure of metazachlor and metazachlor OA at all tested concentrations caused statistically significantly higher mortality, delayed ontogenetic development and slower growth of crayfish. Metazachlor exposure in concentration 22 micrograms/l and metazachlor OA in concentrations 3.2 micrograms/l and 22 micrograms/l caused statistically significant reduction of antioxidant enzymes (SOD, CAT, GR, GST and GSH) levels in whole-body crayfish homogenate. Metazachlor OA showed a more pronounced adverse effect on the early live stages of marbled crayfish than its parent compound, metazachlor. Based on the results of this study we can point out the suitability of crayfish, especially their early live stages for toxicity tests and the possibilities of their use for biomonitoring of aquatic environment herbicides and their metabolites.

Ontogeny of soldier behaviour and its polyethism in termites
Homolka, Petr ; Šobotník, Jan (advisor) ; Frouz, Jan (referee)
The presence of soldier caste is an important synapomorphy of group Isoptera. The adaptation of this caste to defense tasks is more than obvious and some of their morphological or even behavioral adaptations can be quite impressive. The polyethism in termites is relatively well known inbetween rather worker caste. If there are such a studies pointing at polyethism in soldiers, they are connected with soldier polymorphism. The morphological differences are of course important stimulus to role separation. The goal of this thesis was to examine the polyethism in the species of the termite with monomorphic soldiers - Prorhinotermes simplex. I did behavioral experiments with it in enclosed arenas, recorded on specific days. The data shows, that there are differences inbetween individuals and it would be benefical to invest further time to subsequent studies. The thesis bring out new point of view to defensive behaviour of termites and suggests, that even termite species without polymorphic species may have soldiers with different tasks. Besides I managed to map ontogeny of soldier behaviour in the first two weeks after moulting from presoldier instar. Key words: Isoptera, polyethism, soldiers, ontogeny, defensive behaviour Powered by TCPDF (www.tcpdf.org)

Automated monitoring of behaviour as a new paradigm in the research of depressive disorder
Revayová, Anna ; Valeš, Karel (advisor) ; Kubik-Zahorodna, Agnieszka (referee)
The rapid antidepressant effect of ketamine changed the direction of the research of potential antidepressants and its effect was also evaluated in this thesis. However, the main focus of this thesis is a new methodological approach to the research of depressive disorder. The main interest lies with the evaluation of automated monitoring of behaviour in this research. The first aim of this thesis was to evaluate the antidepressant effect of ketamine in the forced swimming test using software enabling automated monitoring of behaviour. The second aim was to meassure the change in phosphorylated Mammalian target of rapamycin (mTOR), using Enzyme-Linked ImmunoSorbent Assay (ELISA). The last, but the most important aim of this thesis was to implement the utilization of Phenotyper boxes in the automated behavioural evaluation of the olfactory bulbectomy model of depressive disorder and also evaluate the effect of ketamine in this model. Ketamine did not show an antidepressant effect in forced swimming test, however this observation could be influenced by chosen dose and mouse strain. Sensitivity of the test to chosen experimental protocol shows insufficient validity of this test. Observed change in level of phosphorylated mTOR corresponded with the behavioural results. Data collected from Phenotyper...

Influence of external conditions on egg incubation in lapwings (genus Vanellus) in temperate and subtropical climate
Pešková, Lucie ; Šálek, Miroslav (advisor) ; Hořák, David (referee)
During incubation, most birds require the presence of at least one parent to ensure suitable incubation conditions for embryo development. The main factors that affect the development of the embryo are temperature, humidity and egg turning. In this work, incubation conditions were investigated in two biparental Lapwing species (genus Vanellus), the Northern Lapwing (Vanellus vanellus), which faces the risk of egg cooling in temperate areas, and the Red-wattled Lapwing (Vanellus indicus), which faces the risk of egg overheating in the subtropics. A laboratory experiment testing the thermal properties of the Red-wattled Lapwing nest lining showed that it selects lining material that slows down temperature growth during egg heating, thus ensuring suitable thermal conditions during parental absence at high ambient temperatures. Temperature and egg turning during incubation were recorded by an artificial egg with a built-in sensors placed in the nests of both target species; data collected by the sensors were stored by a base-station located nearby. The average egg temperature was 32.5 řC for the Northern Lapwing, and 35.0 řC for the Red-wattled Lapwing. Egg temperature in both species fluctuated significantly, affected by many factors. Egg temperature increased with increasing ambient temperature, it...
