Phosphorus in sediments of small rivers
Zborovská, Jarmila ; Hrich, Karel (referee) ; Malá, Jitka (advisor)
This thesis deals with assessment of two small water courses Leskava and Troubsky brook. Streams are evaluated from two aspects: content of three forms of phosphorus TP, Panorg and Porg and hydromorphological assessment. Total phosphorus was determined by sample mineralization by H2SO4+H2O2. Pinorg and Porg were determined by a method published by Pardo. Hydromorphological assessment was done by methodology Králová at al.

Morphological strategies of photoautotrophic protists under various environmental conditions.
Ševčíková, Tereza ; Kulichová, Jana (advisor) ; Pichrtová, Martina (referee)
The aim of this thesis is to provide a comprehensive overview of morphological adaptation of photoautotrophic protists to various environmental conditions and to describe the influence of their shape and size for different life strategies. Thesis summarizes overview of the main factors affecting the natural mikroalgal community and shows their relevance for life of photoautotrophic protists. These factors include availability of nutrients, pH, temperature, penetration of light and predation. Next part focuses on different methodological approaches and attitudes, how to investigate, measure and explain morphological features.

Factors determining soil respiration rate in herbaceous wetland ecosystem
STARÁ, Alžběta
Annotation: Soil respiration represents an important flow of CO2 between atmosphere and soil. Carbon bounded in the process of photosynthesis may be fixed in soil, but also may be released back to atmosphere in the form of CO2. An accurate evaluation of global carbon balance is a key for the estimation of future development of atmospheric concentration of CO2 and prediction of climate changes. The soil respiration of selected wetland biotopes with graminoid vegetation was studied in relation to concentration of soil carbon, nutrient availability, soil moisture and soil temperature during the vegetation season 2008. The observed wetlands included a locality located near the village of Hamr with mineral soil and the nature reserve Záblatské meadows with organic soil. Soil respiration was measured as CO2 release from soil with the use of the equipment LiCor 6400 with soil chamber. The influence of fertilizer application on CO2 release was not proved for either locality. A relationship between soil respiration and soil moisture was found on Záblatské meadows, where the CO2 release declined with increasing soil moisture.
