The species representation of the epigeic invertebrates was found on the grounds of Miroslav. I compared oilseed rape, wheat and maize. The invertebrate capture was done using the method of soil traps. In each crop, I set up 5 ground traps on 28. 4. 2018. I pick up samples from the soil traps at ten-day intervals. The last collection was made on the day of the harvest of the crop (oilseed rape 20. 6. 2018, wheat 9. 7. 2018, maize 5. 8. 2018). I focused on the family of ground beetles (Carabidae). I totally caught 488 individuals from 25 species. In the oilseed rape I caught 231 individuals of 19 species, 102 individuals of 17 species in wheat and 155 individuals of 16 species in maize. I have divided species in the bioindicator groups: E 48%, A 52%. I used ecology characteristics to compare field crops: presence, absence, dominance, Simpsons index, constance, species diverzity, equitability and faunistic similarity.

Structure and function of soil microbial communities in montane spruce forest Martina Štursová Abstract Coniferous forests are spatially heterogeneous environments and represent an important ecosystem that acts as carbon sink under current climate storing large amounts of carbon in standing biomass or as soil organic matter. The formation of organic matter via decomposition of dead biomass and transformation of rhizodeposited organic compounds is primarily mediated by microbial community of forest topsoil. Despite growing insight into the composition of these soil communities, little is known about the microbes actually responsible for those transformation processes, about the drivers shaping these communities or their response to increasing numbers of severe disturbances. Studies presented in this thesis contribute to filling the information. The studies were carried out in unmanaged spruce forests in the highest elevations of Bohemian Forest, in both, the undisturbed areas as well as those affected by bark beetle outbreaks at different time periods. Combination of methods including culturing of fungi, enzymatic activity measurements or high throughput sequencing were used to describe the microbial communities, their distribution in space and time, and factors involved in shaping these communities in those...

This thesis is about the graduates from the Social and Cultural Ecology program of College of Humanities, Charles University, Prague. The theoretical part discusses the subject of values and education from two points of view - in first case as content which is transferred in the educational process, in second it analyzes the result and how education is valued in society - both in postmodern and historical contexts. Section discussing graduate research topics, the evolution of tertiary education in the Czech Republic and the Social and Cultural ecology program is the joining idea between the theoretical and empirical parts of the thesis. The empirical part of the thesis contains survey data from graduates of the Social and Cultural Ecology program from Charles University. The survey targets issues associated with typical degree program progression, subsequent employment, retrospective evaluation of their studies and how they have affected their personal lives.

The purpose of this diploma thesis is to analyze social-spatial structure of the town Most from the point of view of human ecology. The period under consideration is from 1991 to 2011. There is attempt to define local typology of the city, i.e. areas with similarities in the socioeconomic characteristic, its changes and also describe a transformation processes behind it. Trends in spatial differentiation of people are analyzed according to factor ecology. It means that there are used methods of multidimensional statistics like factor analysis and cluster analysis, because of defining the type and strength of certain factors which are specific to the urban areas.

More and more attention of scientists and artists is paid to the effect of sound to human and ecosystems. Due to technology development and growing urgency of human impact new approaches are being formed. This thesis is based on concepts of acoustics ecology by R. M. Schafer. In addition to noise mapping, Czech geographical research does not reflect the growing urgency of sound environment issues. In this thesis I present terminology, concepts and some methods which are used in acoustic ecology or soundscape ecology. A literature search shows the application of these terminology, concepts and methods in a geographical research, specifically in urban and landscape planning, geography of tourism, leisure, health geography or landscape ecology. In an empirical part I followed a pioneering idea of acoustic landscape typology. I used qualitative research, listening walk and narrative conversation, to obtain data about soundscapes. Through these data I critically evaluated and compared acoustic typology of landscape by Hendrych and Hynek (2008). I used recording of soundscapes and spectrograms as secondary methods. Recordings and spectrograms are availabled in ArcGIS Online application. I found out the typology according to Hendrych and Hynek appropriately describes soundscapes from the perspective of...

Population biology and ecology of the species Phyteuma orbiculare L. Abstract This diploma's thesis deals with Phyteuma orbiculare L. (Round-headed Rampion) from family Campanulaceae. According to the law (MŽP ČR 395/1992 Sb.) the studied species is classified as a seriously endangered species of the Czech flora. Two of its distinguished subspecies (subsp. montanum and flexuosum) are on the Red list of vascular plant species (Procházka 2001) of critically endangered species. One of the outputs of this thesis are grid maps of all localities of the species in the following time intervals: until 1949, 1950 - 1989, 1990 - 1999 and 2000 - 2010. As information sources about location of P. orbiculare I used herbaria collections, literature, botanical databases, and Protected Landscape Area Administrative reports. Some data were obtained from botanical experts and some from my personal field-work. One of the main results of thesis is comparison of the distribution of historical and recent localities of the species. I studied chemical composition of soil, species composition and number of flowering plants amount of populations in 21 recent and 19 historical localities in Czech Republic. Recent localities are richer in species and poorer in nutritive substances than the historical localities. Number of flowering...

Previous studies of the relationship between egg size and the embryonic development time showed a positive correlation between the two variables at interspecies level, thus offering the idea that the evolution of the latter could be a limiting factor for enlarging the size of eggs during evolution. Some research into interspecies and intraspecific level of reptiles doesn't confirm this correlation. At the same time, the relationship between the development time and egg size is influenced by many factors, such as shifts in ontogenetic stages of the embryo at the time of ablation of eggs, due to temperature and humidity, the presence of embryonic diapause during embryogenesis or synchronization of hatching time, of which the authors of previous studies took no account or filtered out inaccurately. I think that most of these factors can be well controlled in intraspecific studies, but, variation in egg size within species also tends to be small, which prevents a reliable test for correlation. The solution can be to compare closely related species with high variability in the size of the eggs, in our case the geckos of the genus Paroedura and family Eublepharidae. I eliminated temperature effects by comparing the time of incubation in two equal constant temperatures. The results show that, in this...

The food of the stone marten (Martes foina) was studied in synantrophic enviroment in four localities. Localities were choosen with the aim to follow an urbanization gradient from the center of the city, through its periphery to small villages. The composition of a diet was studied by non-invasive method, by analysis of faeces. Macroscopic remains of the food were divided into eleven categories (mammals, birds, bird eggs, fish, unidentified vertebrates, invertebrates, fruits, vegetative plant parts, anthropogenic material, stones and unidentified remains). 104 different animal and plant taxa were identified. There was often found anthropogenic material. Differences in the diet according the type of enviroment as well as seasonal changes were investigated by comparing of frequency of occurrence and procentual weight of remains. There were found differences between marten's food in urban and rural enviroment, especially as concerned the categories mammals, birds and fruits. Consumption of mammals follows the urbanization gradient, in urban enviroment it is the lowest, in rural localities it is higher. On the contrary, bird frequence was higher in urban environment, in rural enviroment it was lower. Weight of fruit remains was higher in rural localities than in urban ones. There were also seasonal...

The decomposition of plant biomass is associated with changes of the associated fungal community which is crucial in the process of degradation due to their production of extracellular enzymes. Moreover, fungal communities as well as enzymatic activity are specific for soil microhabitats. This thesis focused on the importance of fungi associated with the roots of Norway spruce (Picea abies) trees. Forest with dominating Norway spruce, located in the School Forest Enterprise Křtiny area in Moravia, was selected for the experiment. The aim of this thesis was to compare the community composition of fungi in the roots, rhizosphere and bulk soil and to describe the gradual development of this community after the death of the roots. The next aim was to isolate, describe and characterize those fungi that decomposed roots 5 and 9 months after tree harvest. Identification of fungal isolates was based on DNA sequencing. Degradation capabilities were determined as the activity of enzymes involved in the degradation of lignocellulose. Composition of fungal communities was described by sequencing of environmental DNA on the Illumina platform. Before the flow of assimilates from the live trees stopped, communities of ectomycorrhizal fungi dominated with 60 % of all sequences. Increased abundance of saprotrophic...

Polyploidization is a key mechanism of rapid speciation, with many phenotypic consequences which extent, however, is poorly understood. A deeper understanding of the evolutionary implications of genome duplication is limited due to lack of knowledge of the links between changes in genome, the phenotype of the individual and environmental constraints. Natural lineages closely related to model species represent the ideal systems for addressing such questions. The thesis is thus focuses on highly promising yet overlooked di-polyploid system within Arabidopsis genus. In the western Carpathians morphologically distinct populations of diploid and tetraploid plants of Arabidopsis arenosa grow along a marked altitudinal gradient. Using high-throughput DNA sequencing, measuring morphological characteristics and collecting ecological data of high alpine and foothill populations I try to reveal main trends of genetic and morphological variability of these populations. Additionaly, using morphometrics of natural and experimentally planted populations we want to test the hypothesis whether morphological divergence of alpine and foothill populations has a genetic basis or is driven by phenotypic plasticity. The presented thesis is an important multidisciplinary combination of genetic research on natural related of model...
