Group dynamics for a children's choir camp
Jůnová, Lenka ; Hanková, Zdeňka (advisor) ; Linková, Marie (referee)
The topic of my bachelor thesis falls within the field of leisure time pedagogy. It explores not only the relationships between the members of Sušice children's choir but also their development over time. In the theoretical chapters I focus on leisure education, play, summer camps and the Sušice children's choir. In the practical part I deal with the preparation and implementation of a summer camp with emphasis on group dynamics. The aim of this bachelor thesis is to observe and describe the progress of relationships within the members of SDS during the summer camp. Group dynamics will be described with the consideration of newcomers and their inclusion into the existing group. Based on interviews and observations, it is concluded that the choice of activities contributed to the development of group's relationships. Due to the composition of the teams and the choice of activities, the newcomers were successfully integrated into the existing group.

Effect of type of discrimination task on rate and effectiveness of discrimination learning to avoid aposematic prey in avian predators
Jůnová, Lenka ; Exnerová, Alice (advisor) ; Sedláček, Ondřej (referee)
During the proces of learning to distinguish between edible and inedible prey, predators can encounter different types of prey either sequentially (one at a time) or simultaneously. Sequential as well as simultaneous presentation are used as experimental designs for testing discrimination learning of bird predators in relation to aposematic prey. These tasks can differ in difficulty level for predator which can affect test results; however, rate and effectivity of discrimination learning in sequential and simultaneous tasks have never been experimentally compared. We tested effect of type of discrimination task on effectivity of discrimination learning and memorability of prey discrimination in adults and juveniles great tits (Parus major) in two sequential tasks (regular and random) and one simultaneous task (multiple- choice). The birds learned to discriminate between edible and inedible artificial prey on the first day, and we investigated memorability of prey on the second day. We used colour (alternative red/green) or pattern (alternative dots/stripes) as discrimination cue. Results showed that tits learned to discriminate by colour cue better than by pattern cue. Adult tits learned to discriminate better than juveniles independently on task type. Effect of age and sex was shown in some tasks...

Experimental studies of Müllerian mimetic complexes
Jůnová, Lenka ; Exnerová, Alice (advisor) ; Hotová Svádová, Kateřina (referee)
Mimicry is one of strategies which provides protection for the prey from predator attack. There are several kinds of mimetic relationships, one of them is Müllerian mimicry, i.e. mutualistic relationship between two unpalatable prey species. If there are more animal species in this relationship, it is called Müllerian mimetic complex. Relationships in mimetic complexes are affected by many factors like defence level and aposematic signals resemblance of particular species, their different frequencies, alternative prey, prey community structure or predator species and their experience level. These factors determine whether the relationship of the species involved is mutualistic or parasitic. They also affect predators behaviour and their learning rate, memory and generalisation between mimetic species. Powered by TCPDF (www.tcpdf.org)

"Bohemian Paradise" in the Perspective of Anthropology of Landscape
Jůnová, Lenka ; Pauknerová, Karolína (advisor) ; Šima, Karel (referee)
The thesis discusses how a landscape called the Czech Paradise was nationalized. It primarily shortly deals with the fact, that original Czech Paradise was situated in the area around Litoměřice, which was inhabited mainly by Germans. In the nationally explosive situation in the second half of the 19th century, it became necessary to relocate the Czech Paradise to a purely Czech area. The thesis follows the process of seeking and argues what the main factors for the localization of the new Czech Paradise into the area around Turnov were. The main focus of the thesis lies in following the process of performing concept of the national landscape called Czech Paradise. It is focused, how the landscape was manipulated so that national ideas were materialized. The background of the thesis is the attitude to a landscape, which identifies two movements in a landscape. In the first movement humans are acting on a landscape, in the case of the Czech Paradise a human is nationalizing the landscape and the other movement -is reverse, when a landscape is acting on a human. The thesis is mainly focused on the period from the 1880s to the era shortly before the First World War.
