Genome size evolution in the Zingiberaceae
Pospíšilová, Monika ; Fér, Tomáš (advisor) ; Kolář, Filip (referee)
The purpose of this study is to evaluate the existing knowledge on the evolution of genome size and also to focus on genome in the phylogenetic context. Among angiosperms we find a wide range of C-values (1C = 0.63 pg ? 1C = 127.4 pg), but the modal value is 0.6 pg. We still do not know much about the nature and mechanisms of plant genome size evolution, but we are learning more and more every year. There are already dozens of studies dealing with the dynamics of genome size of smaller taxonomic groups and on four of these they demonstrate possible approaches. Researching within higher taxonomic groups such as families is difficult and so more valuable. New research on the evolution of genome size in the family Zingiberaceae has started and my master thesis dealing with the Globbeae tribe should be part of it.

Genome size evolution in tropical tribe Globba (Zingiberaceae)
Pospíšilová, Monika ; Fér, Tomáš (advisor) ; Zedek, František (referee)
The variability of the genome size reaches several grades even within relatively close groups of plants. The study of the genome size in the phylogenetic context provides interesting results which characterize the evolution of the individual groups of plants. In this respect, tropical plants have yet not been studied. Tropical genus Globba (ca. 100 species) belongs to an economically significant family Zingiberaceae. The diversity centre is found in Thailand but it spreads from east India and southern China up to Indonesia and the Philippines. It is a polyploid complex which exists in two cytotypes within one genus (2n = 32 a 2n = 48); it is characteristic minimally in three out of seven distinguished sections. The aim of this thesis has been a reconstruction of the group phylogeny, discovering the role of the polyploid and evaluation of the genome size evolution of the Globba genus in the phylogenetic context. To this end, modern biosystematic methods were used (flow cytometry, chromosome counting, sequencing of the nuclear and chloroplast DNA regions). Many types of software and statistical methods were used to process and interpret the data. In this group, the genome size was measured for the first time. Out of 87 individuals, the smallest size was measured with Globba nuda (2C = 1.11 pg). The...

Family Planning in the Catholic Church
Pospíšilová, Monika ; Ovečka, Libor (advisor) ; Matějek, Jaromír (referee)
Family planning in the Catholic Church The objective of this research is to understand the difference in theoretical and practical approach to family planning in Catholic Church. Contemporary family planning doctrine is not acceptable for some couples within the Church. This work contemplates separation aspect of the conjugal and procreative aspect of the marital intimate life. This research suggests a need to establish an acceptable birth control solution for married couples who due to medical or other reasons cannot utilize methods based on natural feminine cycle. Keywords: natural family planning, anticonceptive methods, Catholic Church's doctrine, theology of marriage, control of conception
