The plant - habitat diversity relationship in the Křivoklátsko PLA
Nováková, Zuzana ; Chuman, Tomáš (advisor) ; Romportl, Dušan (referee)
The term biodiversity means biological diversity at different levels - from genetic diversity, species diversity to ecosystem diversity. The distribution of plant diversity on Earth is not uniform and it is influenced by various factors. In my thesis I emphasize physical-geographic factors, which include climate, soil and topography. Next I assess the influence of environmental heterogeneity, ecological phenomenons, biotic factors and disturbances. I also assess biodiversity gradients, which include altitude and latitude gradient and size and remoteness of habitats. Another part is focused on the plant-habitat diversity relationship because this relation will be researched in the second part of my thesis. Křivoklátsko PLA was chosen as a model area for its specificity, interest and high species and habitat diversity. The aim of my thesis is to determine the species-habitat diversity relationship in the selected area. Key words: plant diversity, habitat diversity, Křivoklátsko PLA

Physical-geographic aspects of alien plant species distribution in the Křivoklátsko Protected Landscape Area
Nováková, Zuzana ; Chuman, Tomáš (advisor) ; Matějček, Tomáš (referee)
Plant invasions are becoming increasingly more discussed issue, primarily due to a negative impact on global biodiversity. It has also an economic impact and it affects human health. It is therefore important to study the introduction of plant species and their distribution, and monitor them in some way. This is particularly applied to protected areas, where rare species of plants are often endangered. In this work were described factors that affect distribution of alien plant species in the level of plant communities, landscape and large territories. For the practical part of the work has been selected the Křivoklátsko PLA as a model area, mainly because of detailed botanical mapping. There were analysed diversity, origin and distribution of alien plant species. Also the effect of selected factors on distribution of alien plant species in the Křivoklátsko PLA were assessed. The average altitude is the strongest factor. The second strongest factor is the fraction of anthropogenic habitats and moderate factor is the habitat diversity. The length of rivers is weak predictor and the length of roads is very weak predictor of number of alien plant species.

The influence of topography and geology on the functional plant diversity in the Křivoklátsko PLA
Radoměřský, Tomáš ; Chuman, Tomáš (advisor) ; Romportl, Dušan (referee)
Geological evolution resulted in continual changes of the natural environment. These changes are occuring even today and will take place in the future as well. The present form of nature is the result of conflicting effects of endogenous and exogenous processes. The natural environment is increasingly disturbed and transformed by human activities. The final appearance of the landscape has a decisive influence on the distribution of vegetation. In my work I deal with the influence of topography on the distribution of plant functional types. First I summarize in short the paleogeographic evolution of the Křivoklátsko and the near neighborhood from the time of Upper Proterozoic to the present. Further I describe individual physiogeographic factors and theirs influenceon the distribution and diversity of plants. These include geological substrate, topography, soil, climate and disturbance. Shortly after that I characterize the geology, geomorphology, soils, hydrologyand vegetation of the Křivoklátsko PLA. Later I describe ways of expressing the diversity of plantswith accent on the diversity of functional types. My research is based on the analysis of functional diversity of plants and evaluation of the relationship of individual functional vegetation types and the topography. Results of the work...
