This dissertation focuses on treatise of an Italian verb and its development from different points of view of various grammarians through comparison of eighteen Italian grammars from 15th until 19th century. It is looking at the verb from three standpoints: morphological, syntactical, and the aspect. Morphological view - it is examining the way of its classification based on individual grammatical categories: occurrence, description, and its contents. Syntactical view - here the issue of choosing the auxiliary verb is observed in compound tenses, the issue of concord and verbal valency. Verbal aspect, as a separate grammatical category, is not being dealt with by Roman linguistics before 20th century. This dissertation studies if and how authors of older grammars perceive and describe effects that belong to this category, predominantly the expression of perfective and imperfective aspects. Keywords: verb, Italian grammar, morphology, syntax, verbal aspect

This Master's thesis deals with diversity within the Micrasterias papillifera/ M. radiosa (Desmidiales) species complex. Both species are inhabitants of endangered biotops, like peat-bogs and, like other desmids, are used for biomonitoring. Many described varieties for both of them can be found in taxonomic literature, but their morphology is overlapping and revision of this species complex seemed to be necessary. All strains were isolated from peat-bogs and lakes across Europe and my dataset was properly completed by strains from algal collections. Results of phylogenetic analysis of sequences for ITS and psaA showed, that the real intraspecific diversity of Micrasterias papillifera Brébisson ex Ralfs was overestimated. Although I could find a little intraspecific diversity within the ‚papillifera' lineage in the phylogenetic tree based on ITS sequences, it did not correspond with a morphology of isolates. M. papillifera possess unexpected morphological plasticity and also some isolates designated as Micrasterias radiosa Ralfs were present in this lineage. On the contrary, there were only a few isolates in the lineage ‚radiosa'. This species seems to be relatively rare and probably has limited distribution. Both species are morphologically well delimited from each other on the basis of several characters...

This thesis deals with geographical distribution and taxonomy of Steccherinum genus in the Czech Republic. Members of this genus are corticioid fungi of Meruliaceae family, characterized by odontioid hymenophore, small spores and encrusted pseudocystidia. Presence of nine species was confirmed in Czech Republic on the basis of herbarium specimen revision and study of my own collections. Analysis of ITS and LSU nrDNA gene regions was used to create phylogenetic trees. These trees show relations in Steccherinum genus and related species. Selected traits in specimens of S. ochraceum s. l. (number of spines, their length, spore size and pseudocystidia size) were measured. This was followed by investigation of morphological variability in individual specimens and in relationship to ecological conditions (substrate and elevation). Morphology of selected individuals was compared with molecular data afterwards. Two clades were defined in S. ochraceum s. l. - existing differences between them are presumably caused by intraspecific genetic variability. S. rhois could not be separated as individual species on the basis of phylogenetic analysis. Dependence of fruiting body morphology on ecological conditions wasn't supported by results. Maps of geographic distribution of individual species of Steccherinum genus are...

In this Master's thesis I engage in the problematics of the species concept of green subaerial alga Trentepohlia (Ulvophyceae, Chlorophyta). This genus has been studied intensively since the 18th century. For more than 200 years, Trentepohlia species have been delimited using various morphological criteria. However, recent molecular studies showed inadequacies in this approach Therefore, my goal was a precise morphological study of the European Trentepohlia species and the re-evaluation of their phylogenetic position using rbcL gene sequencing. During the period 2013-2015, I carried out a detailed study of the oldest references of Trentepohlia species and compiled a delimitation key of the European species. Based on this research I concluded that it would be desirable to synonymize T. odorata with T. jolithus, as well as T. uncinata with T. arborum. I also sampled Trentepohlia species within Europe and carefully studied and described their morphology. Fresh Trentepohlia thalli were molecularly characterized by cloning, which revealed a common mixture of Trentepohlia species in what on a first sight appears to be a homogenous crust. Phylogenetic analyses based on the rbcL confirmed the ongoing inconsistencies among morphologically and molecularly delimited species and also the existence of cryptic...

Location and climate factors governing morphological features of ice wedge polygons in arctic zone Abstract This thesis reports the geometry of active soil and ice-wedge polygonal network located along the Canadian Arctic and in Alaska. This High Arctic periglacial environment was chosen to ensure active thermal-contraction cracking of permafrost in Holocene allowing comparison of observed ice-wedge polygons with existing climatic data. Geoinformatic software (Google Earth, ArcGIS) was used to obtain and digitalize satellite images of polygonal networks located around Eureka, Mould Bay, Churchill, Rankin Inlet, Inuvik, and Kotzebue. Defined polygonal networks were statistically analyzed in order to define predominant environmental factors controlling morphological parameters of these polygonal networks. Polygon size (overall influence computed on the basis of coefficient of determination) is determined mostly by the duration of development (18 %), frequency of cyclonic passage (17.8 %) and winter air temperature (16.1 %). Conversely, polygon regularity results mainly from nature of the substrate (21.8 %), winter wind speed (15.1 %) and snow cover thickness (12.2 %). Dominant polygon elongation in the polygonal network follows closely the winter wind direction (3/4 of all networks) as the result of snow...

Comparison of Old Norse and Proto-Norse Noun Declension The purpose of this thesis is to follow the development of noun declensions from Proto-Norse to the Old Norse (Old Icelandic) language. The first of the three chapters seeks to give a comprehensive overview of Proto-Norse noun declensions. This overview is based on the evidence of the older runic inscriptions and on reconstruction using relevant linguistic literature. Each of the declensions is presented in the form of a paradigm accompanied by commentary and quotations of preserved grammatical forms. The second and largest chapter presents a survey of Old Norse (Old Icelandic) noun declensions. The survey has two aims. The first aim is to provide a synchronic description of the Old Norse noun declension system which would not be encumbered by an excess of diachronic approach as is often the case in the traditional grammars of Old Norse. At the same time, however, it should show how Old Norse inflectional exponents and classes continue the Proto-Norse declensions as presented in the first chapter. There is also a discussion of some of the systemic causes leading to morphological changes in inflection. The third chapter sums up the previous diachronic analysis and questions the validity of the traditional designations of declension classes based on...

(in English): Typology of verbal suppletion on the ground of Indo-European languages is the focus of the thesis Verbal suppletion in Indo-European languages. The diachronic approach is of special interest. Description of verbal suppletion in the oldest stages of the IE languages and reconstruction of their Proto-Indo-European forms is thus aimed for (for each of the ten well-described IE language branches, one sample language is chosen, and its verbal system and suppletive verbal paradigms are described). Besides the descriptive data from individual language branches, the outcome of the thesis comprises the evaluation of the data by typological means from diachronic and synchronic view-point and its assessment in relation to frequency, semantic fields and Semantic relevance hierarchy. The thesis delivers a review of Proto-Indo-European roots in suppletive paradigms and their mutual relationships.

The aim of this thesis is to devise a method for objective classification of floodplain based on spatially accurate data from UAV that allows identification of the fundamental features of floodplain and channel arising from or affecting by the floods activities. Background research is focused on floodplain forming processes; types of flood on our territory and its geomorphological effects, as well as a brief description unmanned aerial vehicle and their applicability in natural science and the flood. Proposed method was carried out on the test section - a part of meander of Javoří stream in Šumava Mountain - then was tested on complex meander belt of the same stream. Proposed method is based on applicability of standard objective classification. Elementary products from photogrammetric analysis - 2D orthophoto and 3D digital surface model - are used as basic input data. Another aim of theses is to discuss applicability of this method for assessment of fluvial form, its limits and potential development. The results indicated that success of classification will increase significantly the involvement of 3D data to classification, which from standard data from the UAV, despite the lack of absence multispectral bands doing a very valuable source of information for mapping and analysis, for example, the...

This diploma thesis deals with the defectiveness of present converb in contemporary Russian language. The first part outlines the theoretical solutions of converb in Russian language, its origin and diachronic development. The second part presents basic grammar books illustrating the codification of defectiveness of present converb during the 20th and early 21st century. The grammars of Lomonosov, Grech and Vostokov, which illustrate the state of codification in the previous period, are composed to supplement. On the basis of theoretical knowledge and data from the grammars most often forbidding forms of the converbs were chosen and then submitted to corpus analysis. The aim of the corpus analysis was to verify the actual usage of the forbidding forms of present converbs in literary texts. key words: morphology; Russian; converb; codification; use; corpus

Introduction: Genetic determination of human face is clearly visible in family members. The resemblance between monozygotic twins who are genetically identical is especially remarkable. So far the possibilities of reliable prediction of the complex morphology of facial traits on the basis of genome analysis and the ability to capture the variability of human facial morphology through genotype variability are highly limited. Complete genetic basis of the physiological variability of craniofacial traits remains more or less unknown. This master's thesis was created as a pilot study of the shared project of the Laboratory of 3D Imagining and Analytical Methods and the Laboratory of Molecular Anthropology on Department of Anthropology and Human Genetics. Material and Methods: The specimen collection is composed of DNA samples derived from 30 families (29 with 4 members, 1 with 5 members) who fulfilled required criteria. Nine single nucleotide polymorphisms were chosen based on the available information. Eight of them are linked to normal facial variability and one was chosen based on the assumed function of the gene where the polymorphism is located. There were two methods of genotyping: RFLP method with the use of restriction endonuclease and SNaPshot method. Morphological data were provided by the...
