Possible effect of patogens on fttness of selected duck species
Langrová, Anna ; Votýpka, Jan (referee) ; Musil, Petr (advisor)
In total, 76 birds, mainly breeding females, were captured in years 2007-2009. Birds were inspected for the presence of avian influenza (AI) viruses and the AI antibodies. They were inspected as well for the presence of bacteria Borrelia burgdorferi s. l. and Anaplasma phagocytophilum and protozoan Leucocytozoon simondi in blood. The feces were examined for the oocysts and eggs of intestinal parasites. AI viruses were found in 4 cases, while over 80% of inspected birds had AI antibodies. Bacteria B. burgdorferi s. l. and A. phagocytophilum were found in 2 and 1 case respectively. Protozoan L. simondi was not found in any blood smear. The oocysts from protozoan genera Eimeria and Tyzzeria and eggs from roundworm genera Capillaria, Amidostomum and Echinuria were observed in feces. Statistical analyses were due to the small size of our data set inconclusive.
GEOMORPHOLOGY OF VELKÝ AND MALÝ BLANÍK
Bártová, Jitka ; Votýpka, Jan (advisor) ; Verner, Kryštof (referee)
Thie thesis consists of three main parts: an introduction, a description of physical conditions in the studied area and a main part which includes results of geomorphologic research and mapping. The area of interest is situated in central Bohemia in preserved area called Blanik. In the region there are two structural hills where the research was done. The names of these hills are Velký and Malý Blaník. Geologic structure of the region is built of Proterozoic - Paleozoic metamorphic rocks of Moldanubicum. Moldanubicum is represented here by muscovite - biotite orthogneiss (called blanicka ) and muscovite - biotite paragneiss. Both hills are created by muscovite - biotite orthogneiss so all the landforms are of its origin. There were classified structural, cryogenic, fluvial and other landforms in this thesis. Special attention was paid to cryogenic forms: frost - riven cliffs, cryoplanation plateaux, pseudocirques, block fields and many others. Almost 1000 measurements of joints were done. Cloose` s rosettes show systems of joints which prove tectonic system in the region and determine different mezoforms. Mapping brought some more results. Fluvial erosional and accumulative forms were classified as well as the anthropogenous forms. Powered by TCPDF (www.tcpdf.org)
