Attitudes of the Czech Public to Climate Change on Earth – August/September 2023
Čadová, Naděžda
In a survey conducted from the end of July to the second half of September 2023, the CVVM SOÚ AV ČR dealt with the long-standing and highly debated topic of climate change on Earth. We were interested in what the Czech public thinks about this topic. Just three-fifths (60%) of respondents are somewhat worried about the impacts of climate change (15% very worried, 445 somewhat worried), while 38% are not worried.\n\nMore than a half (51%) of respondents are interested in the issue of climate change, with 8% 'very interested' and 34% 'somewhat interested'. More than a quarter (27%) of respondents think that human activity contributes 'fundamentally' to climate change, 37% think it contributes 'a lot' and just under a third (31%) think it contributes 'a little'. Only 3% of respondents believe that human activity is 'not contributing at all' to climate change. 42% of respondents feel personally responsible for climate change on Earth, while the majority (56%) do not feel personally responsible.

Historical and present anthropogenic gradients in landscape
Staněk, Ondřej ; Vojta, Jaroslav (advisor) ; Klinerová, Tereza (referee)
My bachelor thesis is concerned in determining and classification of main anthropogenic influences in various ecosystems. Intensity and direction of landscape transformations such as nutrient income, terrain changes, disturbance, biomass removal or fragmentation is discussed and evaluated. Other landscape factors taking part in ecosystem endurance like different structure and pH of soils or various microclimatic conditions are also taken in notice. It seems that intensity of human influence varies depending on it's nature and it is difficult to propose a linear scale of these changes. From this point of view German hemeroby concept is discussed as possibly suitable scale of human influence.

How human beings influence an amplifying business responsibility in society
Bubnová, Tereza ; Sládek, Karel (advisor) ; Matějek, Jaromír (referee)
The goal of this diploma thesis: The fluence of man on increasing corporate social responsibility is describe the meaning of social responsibility and options how to increase it. Is possible to increase responsibility of corporation by employee or customer? How we can recognize that their behaviour isnť only good promotional tactic as a public relation and commercial? How government can support this behaviour and is realistic to force corporate to be morale with using the right? The result of this thesis will be find out what does it means social responsibility for normal people nowadays and what saying companies especially in Prague. Keywords Social responsibility, corporate social responsibility, ethics, individual ethics, business ethics, environment, human influence, commercial, state, law

Historical position of alpine timberline in the Krkonoše Mts. derived from antique maps and photographs
Vágner, Tomáš ; Treml, Václav (advisor) ; Lipský, Zdeněk (referee)
The purpose of the diploma thesis is the analysis of alpine timberline shifts in the Giant Mountains between 18th and 21st century. The altitudinal position of alpine timberline is a sensitive indicator which reflects human impacts as well as the climatic changes. Methodical approach included the reconstruction of alpine timberlines from the old maps (published in 1765, 1851-52, 1879, 1906) and their comparison with the newer data, which were evaluated from a series of aerial photographs dated 1936 and 2002 (actualized 2005; data provided by supervisor). Data obtained from the old maps and aerial photographs (1936) were compared and verified with old photos and postcards from Giant Mountains. The average altitude of alpine timberline increased during the study period. The increase in elevation of alpine timberline is significant between 19th and first half of 20th century, e. g. in period when the human influence in Giant Mountains decreased. It is concluded that position of alpine timberline in Giant Mountains depended on human influence. Key words: tree line, alpine timberline, human influence, Giant Mountains

Antropogenní vliv na biodiverzitu v komplexu Páramos de Santurban (Kolumbie)
Aparicio Vásquez, Diana Libeth ; Sklenář, Petr (advisor) ; Kovář, Pavel (referee)
Paramo is the name of the region encountered in the upper belt (3 000m - 4 800m) of the Andean mountain ridges from Venezuela to the North of Peru. Paramo ecosystem occupies only 2% of the area of those countries. Nevertheless, paramo flora is the richest high mountain flora of the world (over 3500 species, 60% of endemism). High mountain region of the Northern Andes were almost uninhabited until the arrival of the Conquistadores. At the time of the conquest, livestock and new crops were introduced to the Andean ecosystems. Since that time, paramo has been used mainly for extensive cattle grazing and cultivation of potatoes and onions. During the last three centuries an abrupt intensification of the agricultural practices has occurred. The main aim of this study is to investigate the effects of human intervention, by mean of farming, on species diversity of the paramo vegetation. The study area was selected in the paramo belt of Santurban, Colombian Eastern Cordillera. Ordination techniques were applied to analyze the relation between plant species composition, environmental variables and management variables. We found plant species diversity is influenced by cattle grazing and cropping, but the vegetation changes are mainly determined by the altitudinal gradient. Intensity of human impact is also...

Synanthropic flora of villages on altitudinal gradient in southern part of the Czech Republic
JENČOVÁ, Dana
The study is a floristic survey of 131 villages in southern part of South Bohemia. In total 27.773 floristic records were collected with occurence of 585 taxa of wild vascular plants recorded, 548 taxa were further used in statistical analyses. Environmental factors with potencial effect on village flora composition and diversity were recorded along or extracted from various sources. Relations of diversity (number of species) and environmental factors were studied. Species composition was compared with these variables using multivariate statistical methods.
