Dynamics of moss overgrowth in ditches in restorated drained mires in area of Modrava bogs (Šumava NP)
Novozámská, Eva ; Mikulášková, Eva (advisor) ; Váňa, Jiří (referee)
Eva Novozámská Dynamics of moss overgrowth in ditches in restorated drained mires in area of Modrava bogs (Šumava NP) Abstract This thesis is devoted to a research of induced and natural Sphagnum overgrowth in dammed ditches in restorated drained mires of Šumava National Park within the "Programme of Peatland restoration". Induced overgrowth was studied on the peatlands Cikánská slať, Luzenská slať and Novohuťské močály and 36 permanent experimental sites were established for its study. In 2006 Sphagnum fallax or Sphagnum majus were placed in each site in dependence on the type of locality. For four years increase or decrease of Sphagnum were monitored. The study of natural overgrowth was investigated on the same localities as induced overgrowth. The Sphagnum cover was noted in the year 2009 at 65 sites. The depth of the ditch and the flow of water were the most important variables influencing natural overgrowth and the cover was almost the same on all localities. In the case of induced overgrowth the most important parameters were depth and width of the ditch, amount of the branch support and the interaction of depth and width. The depth of the ditch in the case of natural overgrowth was used to generate a model for prediction of Sphagnum cover. It was possible to compare the induced overgrowth with the...

.Impaired Communication Ability in Premature Infants
Mikulášková, Eva ; Klenková, Jiřina (advisor) ; Korandová, Zuzana (referee)
This Master's thesis deals with the topic of impaired communication skills in premature infants. The thesis is divided into theoretical and practical parts. The theoretical part consists of three main chapters devoted to the development of children's speech, premature babies and care for premature babies. The first chapter describes speech and language, the ontogenetic development of speech, language levels in the ontogenesis of speech and impairment of communication skills in childhood. The second chapter defines a premature baby and discusses the most common postpartum complications. The third chapter is devoted to the care of premature babies in the Czech Republic, describes the logopaedic care regarding such children and their prognosis. The practical part is based on the methods of qualitative research. A triangulation of research methods was chosen - document analysis, observation and interview. The main goal was to describe how impaired communication skills are manifested in premature infants. The partial goal was to find out what postpartum complications occur in premature infants. To achieve the goals of the research, five research questions were formulated. Five respondents were included in the survey, namely four boys and one girl. Based on the obtained data, case studies of individual...

Bryophytes of agrocenosis
Man, Matěj ; Soldán, Zdeněk (advisor) ; Mikulášková, Eva (referee)
This literary review is aimed to bryophytes of agrocenosis in Europe. Researchers usually do not put such interest to agrocenosis, because it is highly human affected biotope. Nevertheless some endangered or rare bryophyte species are found in agrocenosis more frequent than in other biotopes. Bryophytes of agrocenosis are limited by competition with vascular plants, vascular plant composition, soil pH, the way and timing of agricultural management. Factors like use of pesticide, use of fertilizer, or soil type are not significantly correlated with occurrence and diversity of bryophytes in agrocenosis. Bryophytes of agrocenosis have usually strategy of fast life cycle, good adaption to fast use of available resources, high biomass production, high resources allocation into reproduction, high viability of reproductive particles. As a part of my thesis, I compared bryophyte species richness in agrocenosis of European states, where research of bryophyte diversity was already done. (Slovakia, Lithuania, Great Britain and Ireland, Austria). 226 species of bryophytes in agrocenosis was recorded in Europe. I found 18 bryophyte species which was recorded in agocenosis of any of four states. Bryophytes of agrocenosis could comprise 9 - 21 % of national bryophyte species diversity in European states. Most of European...

Biology, ecology and invasion characteristics of Campylopus introflexus in the Czech Republic
Mikulášková, Eva ; Soldán, Zdeněk (advisor) ; Tribsch, Andreas (referee) ; Kučera, Jan (referee)
A B S T R A C T Ecological and economic impact of invasive plants to natural ecosystems is the subject of many studies; however, invasive bryophytes have been stud- ied only marginally. Campylopus introflexus (Hedw.) Brid. is one of the most strongly invasive bryophyte species in Europe. The species appears to be native in the Southern Hemisphere. In Europe, it was collected for the first time in the British Isles in 1941. The moss has expanded eastward and the first collection in the Czech Republic is dated to 1988. This thesis found that more than 70 localities were known known in the Czech Republic in 2006, and more than 100 localities became known by 2011. It has been further demonstrated that the Czech Republic was colonized repeatedly by generative spores and all populations have a unique genetic composition. Genetic variation of the populations is low, the genetic diver- sity of populations within the Czech Republic is not correlated with their geographic position or with any of the monitored environmental variables. At a fine scale within particular localities, the species disperses by vege- tative diaspores, while it uses generative spores for spreading over longer distances. In Central Europe, C. introflexus prefers open coniferous forests, especially plantations of either spruce or pine. It colonizes...
