Miocene fish fauna from the Cheb and Sokolov Basins: taxonomic overview and palaeoecology
Hakalová, Pavla ; Přikryl, Tomáš (advisor) ; Mazuch, Martin (referee)
The aim of this thesis is to present an overview of Miocene fish fauna of the lacustrine sediments in the Cheb and Sokolov Basins, geological settings of this area, and fish associations in individual biozones. Sediments of Cheb and Sokolov Basins were deposited during time interval from Eocene until Miocene in the subtropical zone of the North hemisphere. Volcanic and post-volcanic activities of the Ohárecký rift influenced development of these basins. It's possible define two time sections within development of these basins: early and later; both of them provide rich record of fossil fishes. For the early period of the development is typical smaller range of the lake and its shallow depth. The relicts of this stage are limited to Cheb Basin mainly. Fish fossil record is limited, with three species only: Esox sp., Palaeotinca egeriana and Leuciscus (Palaeoleuciscus) socoloviensis. Low fish diversity could have been affected by poor living conditions or lower taxonomic diversity in general during this time. The later developmental period was much longer. The lake was much bigger - it spread to Sokolov Basin also. The fish fauna diversity is much higher, including taxons Paleotinca egariana, Leuciscus (Palaeoleuciscus) socoloviensis, Aphanius chebianus, Paralebias egeranus and Gobius sp. It is...

Review of representatives of the genus Diplocynodon [Diapsida, Crocodylia] from Czech Republic
Chroust, Milan ; Mazuch, Martin (advisor) ; Přikryl, Tomáš (referee)
The genus Diplocynodon is a basal alligatoroid with a range of endemic distribution in Europe. The oldest known founds are from Late Palaeocen and the youngest known founds are from Late Miocene. Fossils of this specimen are known also from the Czech republic. In the Master thesis were collected more than 600 founds, mostly fragmentary. In the collections of University of Vienna was found almost complete skull of probably genus Diplocynodon darwini from the Czech republic. The main goal of Master thesis is to make a complexe catalogue of Diplocynodon material from the Czech republic. Key words: Crocodylia, Diplocynodon, Czech republic

Analysis of selected fish coprolites from the Loučka locality (Moravia; Oligocene, "menilitic Formation")
Vala, Vladimír ; Přikryl, Tomáš (advisor) ; Zajíc, Jaroslav (referee)
The submitted thesis deals with the analysis of selected fish coprolites found in the Loučka site (Moravia; Menilite Fm.). Eleven specimens was selected (provisionally numbered I-XI) of which two were macerated (specimens I and II). The remaining nine specimens were examined at the surface of the sedimentary layers. Recognizable elements were classified to the following taxa: Keasius parvus, Alopias exigua, Squalus cf. alsaticus, Sardinella sardinites, Anenchelum glarisianum, Palimphyes sp., Palaeogadus sp., Gonostomatidae (gen. et. sp. indet.), Perciformes (gen. et sp. indet.), and Teleostei (gen. et sp. indet.). Composition of the studied coprolites I, II and IV suggest that these were produced by shark species Alopias exigua and Squalus cf. alsaticus. Studied coprolites V, VIII, X and XI were produced by some type of undetermined predatory fish (probably piscivore predator). For coprolites III, VI, VII and IX producer can not be determined.

Evolution of crocodiles (Crocodilia, Archosauria)
Chroust, Milan ; Mazuch, Martin (advisor) ; Přikryl, Tomáš (referee)
Crocodiles (Crocodilia) during their evolution have created many diverse forms. In this work is described their phylogenetic progress with a description of the important groups and taxonomical classification into the families. The classification is based on elder literature upgraded by actual commentaries. The work describes some of their anatomic and morphologic characters mostly of the recent species, which differentiates them from other reptiles or birds groups. In the Czech Republic were founded some crocodile's fragments belongs to genus Diplocynodon from Most Miocene basin. This work includes previous research of these finds. Key words: Crocodilia, evolution, Diplocynodon, Czech Republic

Developmental Morphogenesis of Outer Gills in vertebrates
Crkvová, Barbora ; Černý, Robert (advisor) ; Přikryl, Tomáš (referee)
This study is focused on external respiratory structures of vertebrate larvae. Developmental morphogenesis of the external gills of Senegal bichir (Polypterus senegalus) and Mexican axolotl (Ambystoma mexicanum) was examined together with development of external gill filaments of weather loach (Misgurnus fossilis). Scanning electron microscopy was used to describe external aspects of developmental formation of outer gill structures and classic histology and cryosections with imunohistochemical staining helped to understand internal morphology and developing tissue context. My data revealed that external respiratory structures are in each species formed by dissimilar developmental modes which can clearly be characterized by tissue-specific formation. Whereas external gill filaments of weather loach were found to develop as simple filamentous prolongations of outer ectoderm, in the Mexican axolotl instead, major components of external gill formation seem to be mesenchyme of neural crest and mesoderm origin, which differentiate into extensive connective tissue and muscles, respectively. In the Senegal bichir, interestingly, the lateral expansion of the pharyngeal endoderm was found to be responsible for the early formation of the external gills and this mode of formation is probably derived from the specific...

Research of Cenozoic fish faunae of the selected localities of the Czech Republic
Přikryl, Tomáš
The submitted PhD thesis is presented as a collection of commentaries of fish faunas and its paleoecology at 10 selected localities of Czech Republic. The results were supported by specimens also from other geographical regions. The fish faunae were studied on following localities: Kel , Rožnov pod Radhošt m, Liten ice, Krumví , Vážany nad Litavou, Strachotín, Opava - Kate inky, Ku lín u Bíliny, By ov and Bechlejovice. The summarized results: a) There were recognized direct evidences about feeding habits in following taxa from Menilitic and Ždánice-Hustope e formations: Scopeloides glarisianus, Anenchelum glarisianum, Lepidopus glarisianus, Trachinus minutus, Serranus budensis, Merluccius latus, Oligophus moravicus. b) The partial trophic diagram has been constructed within Menilitic and Ždánice-Hustope e formations (for the region of the Czech Republic). The first trophic assemblage (group A) is composed of species Scopeloides glarisianu, Anenchelum glarisianum, respectively Lepidopus glarisianus, gadiform fishes and invertebrate members. The second one (group B) is characterized by species Serranus budensis, argentinid fishes and in some part of European region (e.g. in Poland) also genus Holosteus. The species Trachinus minutus is not possible to include into any of two above mentioned groups for lack of...

The role of the first (re)lapse in the aftercare - client's and therapist's views
Pavlovská, Amalie ; Přikryl, Tomáš (referee) ; Kuda, Aleš (advisor)
On the background of the attachment in the aftercare center and interest in relapse prevention I chose the question if the first (re)lapse plays some role in the aftercare and what role is it for the topic of my bachelor work. The aims are to map and compare clients' and therapists' views on the same event of the client's first (re)lapse; emphasize that the first (re)lapse needn't to lead to the original stage of addictive behaviour but on the contrary can play a positive role in client's life and process of the aftercare; and critically assess the current status of using of the relapse prevention terminology in practice. (...) All clients of the aftercare center create the basic sample. Two clients were chosen to the sample, experienced a (re)lapse during their aftercare, processed it with the therapists and continue in the programme. The interviews were realized with clients' therapists. The statements of clients and therapists are not too different. There is the question if similar views are result of their joint work or if the clients are under the influence of the opinions of the therapists that they describe an event in this way. I point out the important difference in sights on (re)lapse at all, clients see it especially in the negative way, as a failure, but both therapists describe it rather in the...
