Morphologic-genetic study of populations of salt-water gastropod \kur{Hexaplex trunculus} from Mediterranean sea
MACÍK, Jiří
Variability in genes and shell shape of salt water gastropod Hexaplex trunculus (Linné, 1758) was compared among the samples from three Croatian coastline localities, four localities on Greek island Lefkada and two localities from south France coastline in total number of 464 specimens. Genetical criteria were not found for separating individual populations. No variability were found in 683 bp long fragment of gene for michondrial cytochrome c oxidase subunit one (COI). Differences among populations were not significant, even in conection of my data with the data of recent portuguese study (sequences from GenBank). Differences among populations were found by the geometric morphometric method. Based on these results, morphotypes for certain habitats were determined. During the study, high level of tributyltin (TBT) pollution in the Mediterranean sea causing sexual malformation called imposex phenomenon, was proved in this species of gastropod.

Anabaena - Phenotypic and genotypic diversity of planktonic strains in fishponds and reservoirs of the Czech Republic
ZAPOMĚLOVÁ, Eliška
Morphological diversity of 61 Anabaena populations of 13 morphospecies was described under the field conditions of Czech fishponds and reservoirs. Polyphasic approach was then applied in classification of 45 clonal strains isolated from those populations. Detailed morphological analyses were performed and partial 16S rRNA gene sequences were obtained for 33 of the strains, and secondary metabolite production was evaluated in 20 strains. Plasticity of morphological characteristics under varied conditions of light, temperature, nitrogen and phosphorus was studied in selected strains, as well as their temperature and light growth requirements. The results were then discussed with respect to the delimitation of single Anabaena morphospecies. A new genus Sphaerospermum was defined for the morphospecies Anabaena kisseleviana, A. reniformis and Aphanizomenon aphanizomenoides, whose phenotypic and genotypic features differed considerably from all other Anabaena morphospecies. Unique information was provided on the occurrence and distribution of A. reniformis and Aph. aphanizomenoides in the Czech Republic.

Taxonomy of selected groups of the genus \kur{Caloplaca}
ŠOUN, Jaroslav
The thesis deals with phylogeny, taxonomy and nomenclature of selected groups of the lichen genus Caloplaca. Particularly, the C. cerina group was closely investigated using molecular methods (ITS sequences), morphology and chemistry, based on material from Europe, and to some extent also from North America and western Asia. This approach resulted in the description of three new species (C. sterilis, C. subalpina, C. thracopontica), and detected an unexpected richness of lineages. Nomenclature, taxonomy, morphology and ecology of C. aurantia and C. flavescens from the C. aurantia group were studied in detail, including selection of the neotype of the former species. Their distribution was reviewed for the territory of the Czech Republic. Poorly known taxon C. aurantiomurorum from Algeria was lectotypified and synonymized with C. aurantia. Apart from the two groups, C. phlogina and C. scythica, differing partly in thallus colour and distinctly in distribution, were examined using both molecular (ITS sequences) and phenotypic data and found to be conspecific.

French architectural terminology
MACHOVÁ, Petra
Title: French architectural terminology Supervisor: PhDr. Ondřej Pešek, Ph.D. Author: Petra Machová The diploma thesis is based on a list of vocabulary that are contained in French architectural dictionary Dictionnaire d'Architecture published by Editions Jean-Paul Gisserot. The theoretical part deals with a term in general and describes how the terms are taken over from ordinary vocabulary and back. Furthermore, it describes other ways of vocabulary origin. The practical part is focused on analysis of vocabulary from the dictionary. It studies ways of terms origin. The vocabulary is divided into three parts: loan words in French or words that are part of French lexical substrate, morphologically and semantically developped terms. The objective of the practical part is analysis of each specialised term regarding to its origin. By the end, the thesis contains the comparision of Czech and French architectural terms.
