Zemanová, Pavlína ; Vášová, Lidmila (advisor) ; Rösslerová, Klára (referee)
The master thesis deals with the importance of the book in evolution of the children's imagination. The first part includes short introduction to problems of children's imagination. The second part is engaged in ontogeny of child from prenatal period to the middle childhood and in progress of key competences. It analyzes selected psychological approaches, which had the imagination as a subject of the research. The thesis explains and defines basic terms and processes of the imagination. It deals with a specific phenomenon of the children's imagination and with the evolution of the imagination. The third part introduces typical children's literature, directs on the traditional fairytale and it specifies problems of the literary characters too. It describes the historical development of the Czech book illustration, importance of the illustration in books for children and it also describes children's drawings. The fourth part applies all of previous pieces of knowledges into the work experience in kindergarten. It also describes relations between child and school or child and book. The final part of the master thesis includes summary of the information. [Author's abstract].
Ontogeny of trilobites
Laibl, Lukáš ; Fatka, Oldřich (advisor) ; Budil, Petr (referee)
The thesis summarizes the current state of knowledge about the ontogeny of trilobites. The introductory chapters describe the basic morphology and anatomy of trilobites, and also mention their ecology, occurrence and feeding habits. In the main part of my thesis, I first summarized the existing research in this area, and also dealt in detail with methods of preservation of trilobite larvae, their reproduction, growth, embryology, postembryonal development, segmentation and ecology. I also mentioned the possible usage of this knowledge in other fields (stratigraphy, biogeography, etc.). The last section is a contemporary view on the systematics of trilobites and their position within the Arthropoda.
Vocalization of the common cuckoo chicks: ontogenesis and influence of the host species and acoustic environment
Žabková, Klára ; Honza, Marcel (advisor) ; Linhart, Pavel (referee)
Brood parasitism is a breeding strategy which imposes significant selection pressure upon the host as well as the parasite. Consequently, specific adaptations were formed on both sides. One of the adaptations could be vocal behaviour of brood parasite juveniles. Several conducted studies suggested that juveniles of the common cuckoo (Cuculus canorus) adapt the form of their begging calls according to the host species they parasitize on. However, the outcomes of these studies were ambiguous. Therefore one of my tasks was to verify those findings. Two reed warblers - the great reed warbler (Acrocephalus arundinaceus) and the reed warbler (Acrocephalus scirpaceus) - living in sympatry were selected as the hosts. The structure of begging calls of common cuckoo juveniles raised by these two host species did not differ in any of the measured parameters (syllable duration, minimum and maximum frequency, peak frequency, frequency bandwidth and calling rate). On the contrary the structure of begging calls of own host juveniles varied significantly among the individual species. Moreover, a considerable individual variability was detected in both groups of cuckoo juveniles. Recent studies have revealed that juveniles already perceive sound and acquire knowledge of their parents' voices in the process of...
Ontogeny of personality or repeatability in behavioral and cognitive tests
Pšeničková, Eliška ; Landová, Eva (advisor) ; Sedláček, František (referee)
Individual stability is important for the development of personality, and above all two patterns of consistency - structural and differential. The main goal of this diploma thesis was to monitor changes in the repeatability of behavior over time (i.e., differential consistency) during ontogenesis and to compare the consistency of selected elements of behavior in behavioral tests and a selected cognitive test. Testing of a model species of squamate reptile, the common leopard gecko (Eublepharis macularius), in standard behavioral tests and in a selected cognitive test across ontogenesis over three life stages (juvenile, subadult and adult phase) showed, after statistical examination, high estimates of repeatability and significant influence of ontogenetic phase. Behavioral consistency between juveniles and adults could increase or decrease for certain behaviors or remain consistent in only one phase of life. In the subadult period, the behavior was generally inconsistent, except for vocalization in the reactivity test, where it was demonstrated by high estimates of repeatability. The aim of testing in the selected cognitive test was to determine the non-cognitive component of variability, which could be explained by different personalities. Yet, cognitive styles associated with personality have not...
Manipulation of physical environment and cognition in primates: Ontogenetic development
Kolářová, Anna ; Nekovářová, Tereza (advisor) ; Hradec, Michal (referee)
Cognition is a crucial factor for primates as it allows properly perceive and respond to the surrounding environment. This thesis is devoted to cognitive phenomena, which are often associated with understanding the physical environment and object manipulation. Much attention is focused on causal reasoning, object permanence and tool using. Particular emphasis is placed on the ontogenesis of these cognitive abilities. One of the main questions is how development differs between humans and non-human primates. Despite the fact that non- human primates, just like humans, have a very complex knowledge of the laws of the physical environment, causal reasoning and object permanence develops in a very similar way for these related species, but far from the same way. A large disparity is observed mainly in the area of the pace of development. Tool use in humans and non-human primates is strongly influenced by social learning and traditions. Key words: primates, physical environment, cognitive abilities, causal reasoning, object permanence, object manipulation, tool using, ontogeny
Nautiloidea of Upper Cretaceous epicontinental seas in Europe
Frank, Jiří
The post-Triassic Nautiloidea are not as popular theme within fossils cephalopods research as for example ammonites. They are not very abundant in the fossil records except some rare localities and areas, their morphology is quite conservative and due to the usually poor preservation, their determination and assigning to the species even to genera level is often complicated. Exceptional are taxa with very specific morphology and short stratigraphic and endemic occurrence, which are even suitable for biostratigraphic interpretations. Problematic is also the often poor taxonomical representation of the type material and revision of many taxa is needed. Still nautilids are often represented by reasonable amount in the paleontological collections of natural history museums due to the long history of fossils collecting. Also the scientific literature has been dedicating at least some space to this group since 19 century. The aim of this study is to create an overview about the post- Triassic, especially Upper Cretaceous nautiolidea in the European region of epicontinental seas and prepare a good basement for extensive study of this group. Due to this aim the study is primarily focused on determination of morphological features and also problematic with their interpretation according to the variable...
Study on dynamics of spinning apparatus of some wolf spiders (Araneae: Lycosidae) during their life cycle
Dolejš, Petr
Current knowledge of the spinning apparatus comes namely from studies on orb web spiders and their relatives, whereas that of wolf spiders were more or less neglected. Therefore, developmental changes of the spinning apparatus of four wolf spiders were studied throughout their life cycles. Each of these lycosids possesses stenochronous life cycle with similar number of instars (7-10) but of different length (1-3 years). There is only one period of reproduction in spring/summer in all four species. Sperms are being formed just after the final moult; diplotene in some species is peculiar. The courtship behaviour reflects the microhabitat occupied by the concrete spider species; the copulations are species specific. Ontogeny of the spinning apparatus of developing spiderlings was observed: The spinning apparatus initiate its function in the first instar. Secondary ampullate, all piriform and all but four aciniform glands are tartipore-accommodated; they do not moult in situ. The tartipores, vestigial structures corresponding to spigots of the previous instar, appear on the spinning field starting with the second instar. Tartipore-accommodated glands play roles also during proecdysis and their evolution corresponds with the way how do the spiders secure themselves when moulting. Hence, the not yet...
Eocrinoid echinoderms from mid-Cambrian of the Barrandian area
Nohejlová, Martina
This thesis deals with the topic of eocrinoid echinoderms from the Barrandian area (Příbram- Jince Basin, mid-Cambrian, Drumian). The thesis is presented as a compilation of five published papers and an introduction. The introduction is an overview of current knowledge about eocrinoid echinoderms. It also includes links to new information from the five included papers, and serves as a unifying element for these professional publications. The topic of the thesis is focused on a revision of selected specimens of eocrinoid echinoderms, and the study of their ontogeny, phylogeny, palaeoecology and systematic position. This thesis has also improved our understanding of early evolution of basal blastozoans. This is the first study of Cambrian ontogenetic development on eocrinoid material from the Czech Republic. Complete ontogeny was described on the genus Akadocrinus, and it was possible to establish two basic phases in the development of this genus: pre-epispire-bearing phase and epispire-bearing phase. The new primitive blastozoan Felbabkacystis is described from the Jince Formation - its unique body plan highlights evolution of the body wall among blastozoans. Palaeoecology and phylogeny of the genus Vyscystis was studied, and phylogenetic analysis suggests a basal position of lepidocystoids among...
Ontogenesis of episodic memory in preschool children
Píšová, Martina ; Nekovářová, Tereza (advisor) ; Petrásek, Tomáš (referee)
Episodic memory enables us to remember and recall life events from the past. Episodic memory is a specific type of long-term declarative memory, which undergoes changes in ontogeny. To examinate of episodic memory, "episodic-like memory model", was developed. This model focuses on three basic components of episodic memory: "What happened", "Where did it happen" and "When did it happen". The aim of this diploma thesis is to develop and to validate of particular tests of episodic memory with consideration for their feasibility for preschool children. In order to study episodic memory we used an "episodic-like memory model" and experiments which focused on: children's verbal ability, differentiation of two perspectives during remembering of events and timing memories on an autobiographical axis. We aimed to inspect the effect of age on performance in these tests, possible links between performance in these experiments and the effect of level and the three components of episodic memory on number of errors made. In our dataset we found a significant effect of the age of children in Sentence repetition test and in test of Object collection in the virtual house, in the same test we found a effect of the level on number of errors. We also found a significant correlation between correct responses in verbal...
Ontogeny of the human bone robusticity
Königová, Viktória ; Sládek, Vladimír (advisor) ; Rmoutilová, Rebeka (referee)
Measures of bone robusticity are used in order to reconstruct habitual activity of past populations. The aim of this bachelor thesis is to summarize the development of bone biomechanical properties and to create an overview of the factors affecting the ontogeny of human bone robusticity. The covered influences include genetics, ecogeographical environment and subsistence strategies. An emphasis is put on the mechanical load as it is considered a key determinant of postcranial robusticity. Additionally, the interplay of these factors and its influence on the adult robusticity is discussed. Key words: bone functional adaptation, habitual activity, ontogeny, robusticity, strain
