Structuralism for the 21st Century
Vojtíšek, Martin ; Štojdl, Václav (referee) ; Rozwalka, Szymon (advisor)
Nomos is partly a theoretical project that explores differences between Dutch Structuralism and Japanese Metabolism and tries to find a contemporary architectural system, that is intended as a contemporary interpretation of these movements. The project emphasizes an underutilization of the changeability of our environment and tries to incorporate it into the design of the system so that the user can customize it. It explores ways to combine the benefits of organic growth and modular design through the simulation of a reaction-diffusion. The application of the system shows a possible solution in a specific context with the design of a fragment.

Vliv smíšení porostu na dynamiku růstu borovice lesní (Pinus sylvestris L.) ve Finsku
Vyčítalová, Hana
Mixed stands excel in their species richness and they theoretically have a better precondition for coping with disturbances than monocultures. On the other hand, there is interspecies competition, which may result in the oppression of individual species in the ecosystem. A total of 12 research plots in the province of North Karelia (Finland) were selected to approximate the effect of forest mixing on the growth of Scots pine (Pinus sylvestris L.). In growing season 2018, stem volume changes and drought stress responses were observed in monocultures and with the admixture of one or both of the species Norway spruce (Picea abies L.) and Silver birch (Betula pendula Roth.). The measurement of volume changes was performed using point dendrometers installed on individual pines, the temperature and soil moisture were monitored by a TMS-4 sensor located in the soil in the middle of each research area. It was found that in all cases, Scots pine grew only in dependence on rainwater, not groundwater. It was discovered that individuals in monoculture grew up to twice as much as in both types of mixed stands. They also showed a better ability to saturate the tissues with water after it had been spent for transpiration during the July drought. In August, however, the response to drought stress was comparable in monocultures and mixed stands. The measured results show that interspecific competition may have a negative effect on the growth and drought tolerance of Scots pine in the short term. However, at a time of escalating extreme climate events around the world, this issue needs to be further explored in order to create optimal conditions for the growth of future forests.

Porovnání užitkových vlastností mezi plemeny králíků velký světlý stříbřitý a kalifornský
Sysel, Zdeněk
In the literary part, the bachelor thesis deals with the history of rabbit breed-ing and their quantity in the Czech Republic. It is also mentioned classification of breeds based on their weight and the technology used in small-scale and farm breeding. Next part deal with performance, such as growth rate and car-cass yield. In connection with the performance characteristics, rabbit meat and fur production are characterized. The experimental part describes the comparison of performance character-istics of Californian and Great Light Silver breeds in small-scale breeding. Ob-served animals were weighed regularly from 6 weeks old and slaughtered at 18 weeks old. The Great Light Silver breed achieved better daily growth, on aver-age 35.84 g before weaning and 22.25 g after weaning. The highest growth rates in both breeds were observed in the 7-11 weeks of age. After slaughter, the carcass yield was calculated and the carcasses of both breeds were com-pared again. The average slaughter weight of the California breed was 2262 g and the carcass yield was 54%. The Great Light Silver breed was weighed an average slaughter weight of 2777 g and the carcass yield was calculated to be 56%. The Californian breed excelled in the weight balance of individuals regard-less of gender, the VSS breeds females had better growth ability than males.

Zhodnocení růstu a základních ukazatelů jatečné hodnoty jehňat kříženců plemen romney marsh a clun forest
Minářová, Tereza
The aim of this thesis was to evaluate the growth and basic indicators of carcass value of romney marsh lambs (RM) and crossbreeds of romney marsh and clun forest (CF x RM). The study was carried out in 2019 on the family organic farm in Budeč. The first part of this work is a literature summary that represents problematics of growth and carcass value of lambs. It also deals with the possible effects of various factors on the parameters of growth ability and carcass value of lambs. The next section presents characteristics of the farm and monitored breeds of sheep. The growth was evaluated on the 25 male lambs sample. Live weight was measured at birth, at 70 days, at 100 days and at 130 days. Based on these live weights average daily gain at each interval was calculated. Further, the effect of genotype and interaction of genotype and litter size on live weight and daily gain were evaluated. The genotype had no significant effect on any of the live weights. In terms of average daily gain, the genotype had a significant effect only at some intervals of lamb´s life. Higher live weight at 100 days of age (28.2 kg) and higher daily gain from birth to 100 days (234.9 g) were found out in RM lambs. The effect of the interaction of genotype and litter size was found for most of the monitored live weights and average daily gains. In RM lambs, higher live weight at 100 days (32.0 kg) and higher daily gain in the interval from birth to 100 days (268.4 g) were found in singles. But in CF x RM lambs, these results were higher for twins. For control slaughter 10 male lambs were slaughtered of which 5 of them were RM and 5 of them were CF x RM. As part of the assessment basic indicators of carcass value and the influence of genotype on these indicators, the live weight before slaughter, carcass weight, weight of skin, weight of selected internal organs and right leg weight were determined. Meatiness and fatness were also subjectively evaluated. Slightly better results were found in CF x RM male lambs. In terms of the influence of genotype on carcass value and weight and proportion of viscera, none of the results of the control slaughter were statistically significant.

Maternal effect on body size in the Madagascar ground gecko Paroedura picta
Píchová, Veronika ; Starostová, Zuzana (advisor) ; Vrtílek, Milan (referee)
The maternal effect is a phenotypic process in which the mother influences her offspring through her phenotype, her behaviour and also through the environmental condition that affect her. This non-genetic effect can have a variety of manifestations. One way that mothers of oviparous vertebrates can affect their offspring is through the size of their eggs. This thesis aims to investigate whether and how female of the gecko Paroedura picta can influence the growth and final body size of their offspring. Females of this species can reproduce at an early age and increase the size of their eggs during their lifetime. Therefore, I investigated whether this difference in energy allocation to the eggs would affect the size of the hatchlings and subsequently their growth and final body size. The result shows that the eggs mass increases with female body size and larger hatchlings were born from larger eggs. However, smaller hatchlings from smaller eggs grow faster compared to larger ones and exhibit so called compensatory growth. Only the sex affects final body size of an individual, but this effect is not apparent at hatching. In this gecko, the maternal effect is only apparent in the egg size and hatchling size but it does not affect the growth or final body size of an offspring later in the ontogeny.

Influence of probiotic feed supplements on the growth and health calves
ŠEBKOVÁ, Anna
Thesis contains informations about right stabling and nutrition of calfs. It´s include importance of probiotic supplements and their influence to growth and health of cows. Newborns weight in seven days after birth was similar (54 kg) in every of three groups. Significant diferences were registered at the end of these monitoring, in ninety days after birth. First Group witch consumed RumiForm Digest had average wight 126 kg. Groups witch consumed RumiForm Digest with bacteria mixture, had average weight 146 kg. In every monitored groups diarrheal was detected. The biggest frequency was detected at group, witch consumed RumiForm Digest with bacteria mixture. There was detected 9% diarrheal diseases in total 48 calfs. Deads were detected only in the group of calfs whitche eat RumiForm Digest with probiotics during the experiment. Total mortality was less thas 2%. There wasn´t shown influence of probiotics to calfs growth (p-value (calves weight on the 7th day after birth) = 0,63; p-value (calves weight on the 90th day after birth) = 0,31, p-value greater than 0,5), either to calfs health (p-value (comparison of diarrhea rates) = 0,67; p-value (death) = 0,82, p-value greater than 0,5). Can not be said, that the eating of probiotics supplements had pozitive influence to calfs grow and health.

Zhodnocení přežívání a růstu dvou invazivních raků v teplotně suboptimálních podmínkách
MARKOVÁ, Kateřina
Biological invasions of non-native species are one of the most serious threats negatively impairing global biodiversity. The negative influence of these invasions is especially noticeable in freshwater ecosystems also exemplified by the populations of native crayfish species in Europe. Dominance of non-native species of crayfish over native ones is relatively well known and studied, but the interactions between individual non-native invasive species are significantly less explored. As the range expansion and numbers of non-native crayfish species constantly increases, it becomes apparent that the non-native species will dominate in European waters. However, it is not clear which of these invasive species, and under which conditions will perform better. The goal of this bachelor thesis was to create a literature review focusing on factors that negatively influence the population of the native species (mainly the issue of non-native species and crayfish plague which these species often transmit). Consideration was paid to the importance of the water temperature for the crayfish and to the focused species used in the experimental part the marbled crayfish Procambarus virginalis Lyko, 2017 and signal crayfish Pacifastacus leniusculus Dana, 1852. The experiment was focused on the evaluation of survival, growth, damage to the claws, and the maturation of these species at the water temperature of ~16 °C, which is in the optimal range for signal crayfish, but suboptimal for marbled crayfish (yet, within a range presumably allowing its successful reproduction). If these species should meet more frequently in the wild, it is important to understand their relationships.

Vyhodnocení růstu a zdravotního stavu telat v závislosti na různých chovatelských podmínkách
DUŠEK, Jan
The goal of every livestock farmer should be a viable, well-growing healthy calf that passes on its genetic information to future generations. This thesis deals with the impact of growth and health of calves depending on the selected breeding technology in chosen farm of Holstein cattle. The aim was to compare various ways of housing calves in operating conditions. The chosen hypothesis predicts to achieve better results of calves housed in an individual system (VIB) compared to a group system (VSB). In 2020 a group of calves (n 41), divided evenly into various housing systems (individual /group), was monitored in the selected farm. The experiment lasted from the birth to the 85th day. Based on the results of the experiment, the calves of both observed groups received quality colostrum (average value of 26.17 % Brix) in the sufficient amount (average amount at the first drink 3.45 l). Calves are not weighed at birth in this farm (calves are assigned a value of 30 kg, regardless of sex). The average measured birth weight was 38.4 kg. It would be good to adjust this value in the in-house system to reflect reality better. On the basis of the results of observations, the original hypothesis can be rejected. There was no statistically significant difference between the two groups of calves when compared. It is not possible to confirm / exclude the degree of susceptibility of individual groups of calves to infectious pressures and diseases objectively (statistically) due to a small number of observations. Diarrheal diseases were more serious problem. These diseases occurred most in calves up to one month of their age, with a disease prevalence of 25 % and an average mortality of 7,4 %. No statistically significant difference was found when weight gains were compared. Weaned calves of the VIB housing system showed higher profitability, on average CZK 313 per calf, CZK 2.92 per kg of weight gain. From the point of view of animal welfare, there were problems with scraped backs of the calves housed in plastic sheds (Calf - Tel) because of their height at the shoulder. These sheds had a low entryway (95 cm). In the farm, the milk fed calves are fed from free surface; the teats are not used here. It would be worth considering and testing whether a change of a calf feeding method had a positive effect on the prevalence of diarrheal diseases. This could lead not only to a reduction in costs of potential veterinary care and medicine, but also to an increase in weight gain and thus to higher economic yields.

Beneficial and toxic effects of REE in algae and plants
ASHRAF, Nermeen
Lanthanides mainly represented by REE are the most frequently occurring elements as compared to arsenic and lead. REE consist of a group of elements associated with each other in terms of common physical and chemical properties, with studies concerning phytoremediation and physiological effects of such elements on living biota, is important to be addressed as these elements are frequently being considered as emerging pollutants because of excessive mining and release into the environment. Very important is to study the toxic effects of lanthanum in microalgae under environmental conditions. Experimental trials are evaluating especially potential risks on growth and photosynthesis under nanomolar-dose, with promising decrease and acute toxicity. To this end, the two most promising La-binding protein is currently investigated in green microalgae (Desmodesmus quadricauda) with high affinities. Subcellular localization patterns of La have been also shown to predict possible expression sites and to understand the metabolic response of La in microalgae. We also identify accumulator plant species for LREE in contaminated mining areas for phytoremediation purposes, aim of this study was conducted in the Brazilian mining area for REE and as well as identifying the bioavailable content which can help in predicting the promising species. This field study was done for finding new accumulators which are involved in concentrating LREE in above-ground parts. Our study suggests toxic effects of La and identified preferentially good hyperaccumulator plant specie Christella dentata for phytomining of lanthanides. This could be used as a predictive bioaccumulator in phytoremediation and its further analysis can be a part of future studies for insight mechanisms using analytical techniques, involving the identification of La-binding proteins in Desmodesmus quadricauda.
