Carbon sequestration in grassland ecosystems at various spatial scales
BUREŠOVÁ, Renata
The aim of this work was to get information about the carbon sequestration in selected types of the grasslands ecosystems of regional study area (upper part catchment area of the Stropnice river), and upscale these results to the total area of regional study, eventually to larger areas on the base of maps with different size of minimal mapped unit.Three aspects of the carbon sequestration at sampling sites were studied: biomass production, quantity and quality of litter and decomposition rate. Appropriate aproach to up-scaling method and possibility of usage less detailed mapping layer Corine-LC for carbon stock study was verified through the biotope valuation method (BVM). This method allowed to compare the results on different levels of sample site data generalization.
Bionomics, diurnal behaviour and habitat selection of a vulnerable butterfly \kur{Erebia aethiops} in South Bohemia Bohemia
KLEČKOVÁ, Irena
Erebia aethiops (Esper, 1777) is a lowland representative of prevailingly mountain butterfly genus Erebia (Dalman, 1816). As many other butterfly species, it is declining in Central and Western Europe. I carried out an extensive mark-recapture study of its large population inhabiting Vyšenské Kopce Natural Reserve, the largest complex of calcareous grasslands in South Bohemia, Czech Republic. This thesis relates the demographic parameters to behavioral information, which indicate its habitat use. It also provides original observations of diurnal behaviour and bionomics of this little-studied and ecologically unusual species.
