Biodiversity of green roofs
Matoušková, Kateřina ; Sedláček, Ondřej (advisor) ; Šípek, Petr (referee)
Green roofs offer interesting multifunctinaly solutions to many problems at once. In a small area they bring benefits to people and nature. They thermally insulate buildings, improve the local microclimate and reduce the city's heat island efect. Green roofs improve air quality and also help retain water in the landscape. In combination with solar panels and retention tanks, green roofs can contribute to the modern trend of building green - sustainable - buildings. Green roofs can be used for growing food sources and for relaxation as well. Wild plants can spontaneously colonize green roofs and thereby expand their habitats in cities. The plants create habitats for many animals (especially invertebrates) and provide nectar sources to pollinators. Except food habitats, they offer birds habitat for nesting and resting place during their migration. The aim of this thesis was to evaluate the contribution of green roofs to urban biodiversity. At present, howewer, most scientific studies deal with the advantges of green roofs in connection with enviromental protection or the technical side. A small part of the studies examines the biodiversity of green roofs. My goal was to find out which factors influence a biodiversity of green roofs the most and to design an ideal roofs solution with the greatest...

Analysis of Presentation of Motif of Slum and Life in it in Czech Media in 2010-2017
Kučerová, Zuzana ; Klabíková Rábová, Tereza (advisor) ; Soukup, Martin (referee)
The thesis deals with the media presentation of world slums in the Czech environment throughout 2010-2017. According to the latest estimates, more than one billion people live in slums today. It is safe to assume that the population in these slums will grow in the next decades. Most slums are located in the urban areas of developing states, which have higher urbanisation rates compared to the more developed countries. Slums are crowded places in cities where the residents live in substandard conditions that includes lack of drinking water, poor sanitation, lack of sewerage and health care and so on. The thesis focuses on the media coverage of five slums (Kibera, Dharavi, Khayelitsha, Ciudad Neza and Orangi Town), which rank among the biggest in the world. The work briefly summarizes the social construction of reality theory according to T. Berger and P. L. Luckmann, the media construct of reality and news value. It explains the concepts of slum, developing country, urbanisation, and the refugee crisis. It examines the texts by combining quantitative and qualitative content analysis. Quantitative content analysis is based on three research questions and six hypotheses. Newton Media database used for the research provided relevant contributions from newspapers, magazines and their internet mutations,...

Effect of urban gradient on composition of bat communities in Central European landscapes.
Kočí, Jakub ; Lučan, Radek (advisor) ; Andreas, Michal (referee)
Bats (Chiroptera) are usually considered as a group greatly endangered by destructing their habitats through the human activity. However, a significant part of bat species at the central Europe use human buildings as shelters, moreover the natural shelters are marginal or unknown in several species. Considering the linkage of the great part of our bat species to the fragmented area and in connection with a long term human influence on the central european landscape we ask whether at least part of our species see human activity through providing proper shelters as positive. Based on the analysis of landscape structure and ruggedness effect on density, diversity and population structure of bat assamblages acquired by standardized mist net captures located in lowlands (elevations below 500 m) of Czech Republic (204 localities, 3585 bats, 22 bat species), we found that even though most of reactions were species specific and few species seemed to be positively associated with urban environments, most of the bat species rely on the broad-leaved forest cover and other natural habitats such as water bodies. The most significant factor influencing sexual segregation for bats was ruggedness of surrounding landscape. Keywords: Bats, Chiroptera, fragmentation, Europe, temperate zone

Species traits and ecological conditions linked to bird colonisation of cities
Grünwald, Jan ; Reif, Jiří (advisor) ; Sedláček, Ondřej (referee)
Human settlements are a novel habitat type and species must respond to its ongoing expansion. For effective conservation of biodiversity, it is important to understand the mechanisms underlying these responses. This thesis focuses on urbanization in birds, from both the individual and community perspectives. The aim of this thesis is to find out if there are any "pre-adaptations" in some bird species to be successful city dwellers or if all birds can potentially exploit the urban environment when local conditions allow. According to the reviewed literature, I conclude that the urbanization in birds is not a universal pattern, but there are some specific traits shared by most of the urban birds. The successful urban species are mostly omnivorous or granivorous, they breed in trees or in cavities and, they are often ecological generalists. They are sometimes represented by non-native species occurring in the cities all over the world.

New Old Brno Return of living to the city centres
Lysá, Karolína ; Kaštánková, Jana (referee) ; Františák, Luboš (advisor)
The thesis deals with the topic of return of housing to the city centers. It is divided into three sections. In the first part I analyze the area concerned. The analytical part is followed by an urban study, which offers a solution to the reurbanization of the site. The last section is devoted to urban detail - a residential block divided into eight apartment buildings, four of which I work on at the level of an architectural study.

Effects of urbanization on the landscape of a Modern City in Ghana: A case study of sunyani
Boateng, K. A. ; Mensah, Caleb ; Agyei, Thomas ; Švik, Marian
Changes in land use through urbanization and agriculture are the key anthropogenic effects of climate change. Thus, the preservation of natural environment of urban areas is essential for conserving water and soil, while still adjusting the microclimatic variables (temperature, precipitation, relative humidity, etc.) and stabilizing the natural ecological system from destruction. It has been observed that most parts of city's green vegetation have been lost due to housing developments and commercial activities. This study was carried out to assess the effect of the change in land use on a modern city like Sunyani, by observing the significant changes in vegetation cover from LANDSAT TM imagery over a 31-year period (1986 – 2017). From the study, there was significant decline of vegetation cover from 1986 to 1999, and no significant change from 1999 to 2017. There were also significant changes in the built-up areas from 1986 to 1999 and no significant change from 1999 to 2017. Adoption of sustainable and environmentally friendly technologies that maintain open green vegetation is recommended for future city planning.

On the assessment of urbanization application in weather forecasting model
Nováková, Tereza ; Halenka, Tomáš (advisor) ; Žák, Michal (referee)
Built-up areas represent an artifiial impait to natural environment with large spatial variability and speiifi meihaniit radiationt thermal and ihemiial properties. Despite of inireasing horizontal resolution of numeriial weather prediition modelst the impait of loial built-up area on mesosynoptiv weather phenomena is still not well resolved. Therefore it is neiessary to use some of urban environment modelst whiih were designed to parameterize speiifi urban prosiessest not expliiitly resolved inside the grid box. In the thesis main urban iharaiteristiis are explained (impait on the struiture of boundary layert radiation and heat balanie of urban environment or urban heat island)t basii priniiples of urbanization appliiation in the numeriial weather model are desiribedt as well as different urban parameterizations available in numeriial model WRFe (Weather Reseaih and Feoreiasting). Number of validation experiments were performed for summer and winter episode in non-hydrostatii mode at 3t3 km resolutiont where different urban parametrizationst antropogenii heat adjustment and impait of mosaii land-use were tested. April 2018 Prague weather foreiast was verifiated in ionsideration of urban heat island.
