Influence of meadow management on the migration behavior of selected species of butterflies
Bubová, Terezie ; Langrová, Iva (advisor) ; Farkač, Jan (referee)
Migrations are the key process and one of the basic biological features, which allow survival of endangered species in fragmented landscape. In the last decades, agriculture intensification, industry and urbanization caused that number of natural butterfly habitats has significantly decreased. The localities originally suitable for butterflies are currnetly converted to farmland or building plots. This PhD thesis aimed to find a compromise solution of meadow management, which should allow a commercial use and concurrently do not jeopardize the continued existence of endangered or threatened species. The main idea of this study was in the intentional emigration causing in the middle of flight period, which should lead into resettlement of the population to another (potentially more suitable) locality. Possibility of aimed manipulation with butterfly emigrations would be considered as a major breakthrough in their protection.
The investigated species Phengaris nausithous (Bergsträsser, 1779) and Phengaris teleius (Bergsträsser, 1779) are both considered to be flagship species for protection of European butterflies at open meadows. This study is based on research, which was carried out in 2013-2015 at 17 patch in localities Dolní Labe, Czech Republic. In above mentioned years, one selected meadow was mowed in the middle of flight season and the emigrations were then monitored using mark-release-recapture method. Results of population and migration characteristics were calculated in MARK 8.1 software. Subsequently, the effect of mowing on emigration (comparison of emigrations from the meadow before and after mowing) was evaluated using Statistica 13.
The hypotheses of this study were based on the assumption, that the loss of resources after well-timed mowing should increase the activity of adult butterflies. During the monitoring, number of emigrations was increased only in flight season 2015. Unfortunately, the statistical evaluation did not show significant effect of mowing on migrations. On the other hand, the hypothesis dealing with colonization of nearest meadows was confirmed.
Effect of intentional emigration caused by management interventions was unfortunately not proved. However, we found out, that even though the population at one mowed meadow decreased clearly, the metapopulation size at the locality remained more or less stable.
At investigated (mowed) meadow, there was observed a sharp decline of P. nausithous abundance. On the other hand, P. teleius population was only slightly reduced. It is therefore conceivable, that P. teleius are not as susceptible to innapropriate term of mowing. The results obtained in our research conclusively displayed no possible positive effect of mowing in the middle of flight season and a necessity of suitable management maintenance at localities inhabited by Phengaris butterflies.

Navigation of mobile robots
Rozman, Jaroslav ; Matoušek,, Václav (referee) ; Šolc, František (referee) ; Zbořil, František (advisor)
Mobile robotics has been very discussed and wide spread topic recently. This due to the development in the computer technology that allows us to create better and more sophisticated robots. The goal of this effort is to create robots that will be able to autonomously move in the chosen environment. To achieve this goal, it is necessary for the robot to create the map of its environment, where the motion planning will occur. Nowadays, the probabilistic algorithms based on the SLAM algorithm are considered standard in the mapping in these times. This Phd. thesis deals with the proposal of the motion planning of the robot with stereocamera placed on the pan-and-tilt unit. The motion planning is designed with regard to the use of algorithms, which will look for the significant features in the pair of the images. With the use of the triangulation the map, or a model will be created. The benefits of this work can be divided into three parts. In the first one the way of marking the free area, where the robot will plan its motion, is described. The second part describes the motion planning of the robot in this free area. It takes into account the properties of the SLAM algorithm and it tries to plan the exploration in order to create the most precise map. The motion of the pan-and-tilt unit is described in the third part. It takes advantage of the fact that the robot can observe places that are in the different directions than the robot moves. This allows us to observe much bigger space without losing the information about the precision of the movements.

Consumption of fiber in old age
ŠÁLEK, Jan
The theme of this bachelor thesis is the Consumption of fiber in the old age (seniors). Formerly, the dietary fiber was considered unnecessarily burdensome for human organism. Later, it was found that it has a relatively large impact on human health, especially by serving as a prebiotic for symbiotic bacteria inhabiting the gastrointestinal tract. There is still prevailing opinion that roughage divides into a soluble and insoluble, despite that some types of fiber cannot be definitely classified and placed into any of these groups because they have characteristics of both of them. The daily recommended dose is 30 g. The qualitative research was used for elaboration of the practical part. The first goal was to find out how much fiber seniors consume. The second aim was to compare the consumption of fiber among elderly people living alone and the elderly living in retirement homes built for them. The research group, at the first research question, consists of 20 seniors from the Southern Region aged over 65 years. The research group, at the second research question, consists of five retirement homes from the whole Czech Republic. All respondents were given a record sheet for one week, and instructions on how to fill it. Acquired menus were subsequently re-calculated through the program "Nutriservis Professional". The results show higher consumption of fiber than the average in the Czech Republic, but there is still almost a half missing to get the recommended daily dose. There was observed BMI and its impact on the consumption of fiber. No significant effect was found, because overweight had all interviewees except one respondent. The financial limit is visible for evaluated diet of homes for the elderly, therefore, there are no whole grain products, vegetables and almost no fruit. Despite these limitations, the average consumption of fiber is almost equal to elderly people living alone. In conclusion, there is a proposition how to, despite the low funds, increase the intake of roughage, and avoid or, at least, reduce the problems associated with its low consumption. Recommendations for respondents are individual and given under each evaluation.

Diets for food allergies
DOBRUSKÁ, Klára
I have chosen topic Diet with Food Allergy as a topic of my bachelor thesis. This illness is quite common these days. It affect infants mostly but allergy of cow´s milk protein of children under three years disappears itself mostly. There is increasing amount of causes when patient suffers more allergies. Number of people who have the most serious reaction the anaphylactic shock, icreeases. It can end with death. Doctors recommend to patients to strictly follow the elimination diet which is basic treatment of this illness. The most accurate diagnosis of illness (immunological or not) is another important factor for effective treatment. I have chosen three aims for this bachelor thesis. First to find out if patients are informed about their illness. Second to map eating habbits of people with food allergy. Third the evaluation of correctness of daily menus. I used approach of guality research. Research group consisted of six respondents with different food allergy. Those respondents wrote down their weeks menus. Menus were evaluated with program Nutriservis and it was assessed if it follows recommended dietary value. Suitable intake of energy and essential nutrients was calculated for every respondent. It was evaluated if respondents follows priciples of rational diet and if their diet contains sufficient amount of minerals and vitamins. Questionnaires were another key point of this research. Questionnaires were about illness know-how of patients and who has instructed them about it. It was found out the patients hasn´t got enough information about their illness and half of them has no idea which essential nutrients, minerals and vitamins could lack in their diet. It resulted from menus simultaneously that five of six respondents do not follow principles of rational diet and eat very monotonously. Only one respondent follows strictly elimination diet others violate diet exceptionally. Respondets would appreciate other research would focus on creation of special centres and training of doctors and nutritional therapist who would be focused on food allergies. Spreading the information about illness not only to patients but to public also is really important. Another important point is to increase amount of books about food allergies at the market.

How to prevent the proliferation of Legionella pneumophylis in hot water in the hospital Czech Krumlov
TUREK, Jan
This diploma thesis deals with microbiological quality of hot water in a hospital in Cesky Krumlov as well as hot water piping condition with respect to Legionella. It also deals with arrangements for improving the quality of hot water in this hospital. The subject and target of this thesis are the findings of the mentioned parameters based on own observations, technical documentation and analysis of warm water performed by an accredited laboratory. The hospital in Cesky Krumlov, the construction of which began in 1909, was built in 1911 as the 'Nemocnice Císaře Františka Josefa I.' As the time went by, new buildings were built up. The hospital was renamed to 'Všeobecná veřejná nemocnice' in 1942. In the following years the hospital expanded until the current condition. Water quality and presence of Legionella is a world-wide issue, which we must fight against. The thesis is divided into two parts. First, theoretical part, which includes both general and specific knowledge about Legionella, its health risks, the environment in which it occurs, possibilities of eliminating, suitability of the material for hot water pipes, gained in professional literature and a part of the Czech legislation dealing with public health protection, the law 'No. 258/2004 Coll.' in actual version and quality of drinking water and hot water. In the second, empirical part, I focus on the situation of the hospital in Cesky Krumlov from 2009 till 2015, concerning newly built boiler room and the whole distribution system of hot water regarding Legionella. Particularly I focused on materials used for ecologisation of the gas boiler room and materials used for hot water pipes and actual state of water distribution in individual buildings of this health care facility. I mentioned the analysis of the water samples performed by an accredited laboratory with corresponding technical documentation, which concerns the water distribution system, provided by the medical facility. I used secondary data analysis to evaluate these documents. Regarding the results from 2009 to 2015 the microbiological quality of warm water doesn't meet the limits defined in the Attachment No. 3 of the above mentioned law Order 252/2004 Coll. Limit value for colony forming units of Legionella is set to maximum of 100 CFU. In most of the samples this limit was exceeded by series of units up to hundred thousands of units. The last results in 2015 prove improvement of the unfavorable situation. In that year the analysis was tested three times. First in February, where the CFU units were 'only' in hundreds, with the top value of 550 CFU in the Postacute Care ward. Second analysis was performed in June that same year. Results were acceptable. The highest value was 64 CFU. Last analysis in the hospital was performed in December. Increased concentration of Legionella was again in the Surgery building. There were established of 1400 colony forming units. There were 300 CFU in the Postacute Care ward and the limit value of 100 CFU was in the ward of Internal medicine. The answers to research questions 'How to prevent reproduction of Legionella peumophylis in the water distribution system of the hospital in Cesky Krumlov?' and 'How to ensure a sufficient amount of quality hot water in the medical facility?' are included at the end of the stated recommendations. A risk factor causing the fast reproduction of Legionella is the old water distribution system in most of the buildings and low water temperature of water leaving the boiler, which is 55°C. All mentioned results and evaluations are included in this thesis as well as attached pictures, which show the environment and situation within the Health Care Institutions.

Biology, occurence and regulation possibilities of Viola arvensis Murray in grown plants
MACHÁČEK, Václav
This thesis concerns on biology, occurrence and especially, herbicide regulation of Viola arvensis Murray on arable land. On the land of the farm DZV NOVA Bystřice a small-plot experiment focused on monitoring and regulation of Viola arvensis was carried out. This experiment was carried out from September 2012 to January 2014 on three crops (winter wheat, winter barley and winter rape) in three locations. In the theoretical part we describe the biology and occurrence of this frequent weed. The aim of the thesis was to evaluate the abundance of Viola arvensis and other weed species and verify the effect of different herbicides on Viola arvensis and other weeds. The effectiveness of the tested herbicide combinations was statistically significant for Viola arvensis and also for the other weeds (P 0, 05). The exceptions were Veronica persica, Geranium pussilum and Hordeum vulgare, where the effectiveness of these agents was not proved (P > 0, 05). The results summarize the numbers of weed species and effectiveness of applied herbicides. Viola arvensis was the most frequent weed species found on the examined sites. The effectiveness of herbicide agents used against this weed was very high. The highest was by preparations Maraton + Glean 75 WG, Maraton + Logran 20 WG, Cougar Forte + Logran 20 WG a Sumimax + Glean 75 WG (100 %). Lower was by preparations Butisan 400 SC + Command 36 SC (80 %) a Butisan Star + Garland Forte (75 %). In the winter barley and winter wheat, the applied herbicides were 100% effective, only in the winter rape the effectiveness was lower (75 - 80%). I can confirm the initial hypothesis about the effectiveness of the different herbicides on field pansy because their effectiveness differed.

Evaluation of FGMRI provenance plot with European beech (Fagus sylvatica L.) on the locality Jíloviště, Baně (Central Bohemia)
Kuklová, Alena ; Podrázský, Vilém (advisor)
Buk lesní (Fagus sylvatica L.) je nejvýznamnější listnatou dřevinou České republiky. V minulých letech se jeho zastoupení velmi snížilo v důsledku nešetrné těžby, přírodních disturbancí a následně hlavně změnou lesního hospodaření, kdy se upřednostňovaly především jehličnaté dřeviny smrk ztepilý (Picea abies) a borovice lesní (Pinus sylvestris). Provenienční výzkum se, díky jejich preferování při pěstování, nejprve věnoval hlavně jehličnatým dřevinám, až v pozdější době se zaměřuje i na dřeviny listnaté. V současné době se naše lesní hospodářství k buku znovu vrací a jeho zastoupení se v našich lesích pomalu opět zvyšuje.
Úkolem diplomové práce je provedení terénního šetření na provenienční výzkumné ploše VÚLHM Strnady č. 82 Jíloviště, Baně ve věku 34 let (zjištění počtu rostoucích jedinců, tloušťkového a výškového růstu, tvárnosti kmene, větvení, úhlu větví, tloušťky větví), zjištěná a naměřená data statisticky zpracovat a vyhodnotit rozdíly mezi testovanými proveniencemi buku lesního.
V první části práce je zpracována literární rešerše, zaměřena na provenienční výzkum buku lesního, v další části jsou statisticky zpracovány kvantitativní a kvalitativní znaky zjišťované na výzkumné ploše. V poslední části jsou vyhodnocená data porovnávána s daty z minulých let.

Analysis of sheep utility attributes in ecological and conventional flocks in the Czech Republic
Linhartová, Iveta ; Ptáček, Martin (advisor) ; Jan, Jan (referee)
The goal of this diploma thesis was to perform an analysis of sheep breeding of Suffolk breed in basic reproductive performance and meat production traits aspects. The information for rating these aspects was used from two farms. The first of them used conventional way of breeding (ZVOZD Horácko, družstvo) and the second one used ecological way (EkofarmaKosařůvmlýn, s.r.o.).
Fertilization, fertility, intensity and rearing belong among monitored reproductive indicators. These reproductive indicators are expressed in percentages. Regarding meat production traits rating in this thesis we compared influences of year of lambing, farming method, birth month, sex, litter size and age of dam. All these influences were judge according to birth weight (kg), weight at the age of 100 days (kg), average growth (g), depth of the longest dorsal muscle (mm) and according to depth of subcutaneous fat (mm). Reproductive performance and meat production were monitored in years 2011, 2012, 2013, 2014 and 2015.
In terms of reproductive performance with a few exceptions it was true that ZVOZD Horácko, družstvo reached the best values, and in most cases better than the national average. For example in terms of intensity values in 2012 ZVOZD Horácko, družstvo had 35,9% better results compared to national average. In the same year this farm reached 48,1% higher values of percentage rearing compared to national average. Ekofarma Kosařův mlýn, s.r.o. showed worse performances, however it was in most cases better than national average. In terms of intensity in 2011 Ekofarma Kosařův mlýn, s.r.o. had the same results as the ZVOZD Horácko, družstvo. Meat production properties were supported by statistical calculations and all of them were conclusive at least at the level of significance P < 0,05 in all cases except month of birth effect on birth weight. The best results of meat production in terms of effect of lambing had the year 2012, when the birth weight was one of the highest and the other properties (weight at the age of 100 days, average growth, depth of the longest dorsal muscle, depth of subcutaneous fat) were by far the highest in the period of 2011-2015. Next we found out that the ecological way of breeding (in this case Ekofarma Kosařůvmlýn, s.r.o.) has better results than the conventional way (ZVOZD Horácko, družstvo).
The effect of birthmonth has the significant influence on the indicators of meat production and the lambs born in April had the best results. In the case of sex rams are better. Litter size has very important influence on meat production the more lambs per one mother, the lower
birth weights, the lower weights until the period of weaning, the lower weights at the age of 100 days. It is affected by milkiness of the mother. Moreover, the age of mothers also play a significant role. In our research the highest birth weights had lambs of one year old mothers and all other indicators were the highest in the case of three year old dams.

Characteristics important for ensuring of sustainable and development of dairy cattle herds breeding
Lelek, Jaroslav ; Stádník, Luděk (advisor) ; Petr, Petr (referee)
The aim of this dissertation was to assess the influence of characteristics important for
ensuring of sustainable and development of dairy cattle herds breeding. The data investigated
describe approximately 5138 dairy cows in period of four years in selected farming´s of dairy
cattle in district of Jičín. There were these indicators of reproduction processed: conception
rate after first insemination, conception rate after all inseminations, interval of insemination,
index of insemination, service period and meantime; the data were collected from seven
stables of Bohemian Spotted cattle and from seven stables of Holstein cattle. The longevity
was investigated from the number of dairy cows at respective lactation of both investigated
breeds and from the average lactation in respective years. The results of investigation prove
that the average percentage representation of dairy cow at respective lactation between
2012-2015 ranged 33,4 % at first lactation, and 24,68 % at second lactation, and 18,13 %
at third lactation, and 11,48 % at fourth lactation, and 6,53 % at fifth lactation, and 3,32 %
at sixth lactation, and 2,36 % at seventh and more lactations.
The evident data from comparison prove, that till third lactation there is higher percentage
representation of Holstein cattle and from third lactation there are more cows of Bohemian
Spotted cattle, and also the average reached lactation confirms this the value of 2,75 lactation
for Bohemian Spotted cattle and the value of 2,3 lactation for Holstein cattle. The influence of
breed on the average length of lactation was quite weak. The results of rating indicators of
reproduction also have not proven any statistically important difference between both types of
cattle as concerns values reached by each cattle, but the original Bohemian Spotted cattle
reached better results in all indicators, and thus it is probably more suitable for the area of
district Jičín.
