Effect of castle ruins on diversity of vegetation in the landscape
Javorský, Tomáš ; Münzbergová, Zuzana (advisor) ; Prach, Karel (referee)
Medieval castle ruins undoubtedly create the face of the Czech landscape. Moreover, the few previous studies on this topic have shown that ruins are unique and extraordinary biotope. This work aims to characterize castle vegetation on thirty examined localities (thirty ruins). Phytosociological relevés and soil samples were collected, soil depth was measured and the cover of individual layers was observed - all of this on three spots on each locality. One of the places covered castle and the other ones the nearby forests (each one was chosen differently than the other). The castle walls were sampled separately. The results show that castles not only increase the diversity of forests by hosting a higher number of species but also by a different species composition - castles have a rather large set of species with high fidelity to ruins areas. Approximately half of the uniqueness of the ruins can be explained by the soil qualities, such as higher pH, higher quantity of calcium and magnesium, the other half remains unclear notwithstanding the usage of various explanatory variables. It is certain that castle ruins are from a biological point of view exceptional, unique and they surely deserve the attention which we owe them so far.
The effect of earthworms on plant communities
Čápová, Kateřina ; Frouz, Jan (advisor) ; Mudrák, Ondřej (referee)
The thesis provides a literature review, which mainly deals with the distinction of short-term and long-term effect of earthworms on the soil. The work describes the whole process of succession, succession on dump, the research part is carried out on land from dumps. The influence of plants on soil and the influence of soil on plants are described. As well as the effects of biota on soil and soil on biota. In particular, the effect of earthworms on the area and the distinction between short-term and long-term earthworm effects are described. The research part deals with the distinction between short-term and long-term effects of earthworms on the soil and plant growth. Above all, a detailed analysis of the soil on which the pot experiment took place. Aboveground and underground biomass and growth of early and late successive plant species were examined, as well as soil pH, conductivity, microbial respiration, PLFA, ergosterol, determination of NO3-, P, carbon, nitrogen, sulfur and C: N ratio. Thanks to these analyzes, we can better distinguish our investigative issue. The results of my work showed a significant effect of both the immediate presence of earthworms and long-term presence on plant growth and microbial activity. These interactions have been shown to have a complicated pattern during...

Rozdělení primární organické půdní hmoty v kambizemích a pseudoglejích oblasti Třeboňska
VRZÁKOVÁ, Miroslava
An assessment of the method of calculation of the humus content in soils by multiplying the factor 1 724 and Found That this conversion is unsuitably. The Western Třeboň Soil The new method has been Demonstrated in Patent MS 304,265th The main soil types and have a narrow cambisoils pseudogleys Trebon region and the high humus content the primary PPOH. Soil acidity is mikroedafonu causes limiting the activity of soil.
Koncepce a metodologie komplexního studia dlouhodobých trendů vývoje krajiny v užším a širším zázemí JE Temelín: Stanovení potenciálních změn kvalitativních a kvantitativních parametrů půd s ohledem na způsob a intenzitu jejich využívání a zranitelnosti vůči antropogenní zátěži na základě historických podkladů a aktuálních výsledků sledování

Podrobný popis geomorfologických a geologických poměrů sledované lokality. Byla navržena umístění kopaných půdních sond tak, aby zahrnula nejdůležitější půdní jednotky oblasti a současně napomohla upřesnění půdních map, zejména u přechodu zemědělská půda - půda lesní. Výsledky sledování - geomorfologické poměry, geologické poměry, výsledky fyzikálních a chemických analýz. Byla vytvořena pracovní verze nové digitální mapy půd zájmového území.
