Microstructure of a tribosphenic molar - comparative analysis
 ŠPOUTIL, František
The proposed thesis concerns in the study of tribosphenic molar, the key apomorphy of mammalian clade, mainly in structure and development of its enamel coat. As the main model species served us European vespertilionid bat Myotis myotis. The aims of this thesis are: (1) to describe structure and microstructure of enamel in tribosphenic molars in detail; (2) to compare it with unicuspid teeth of the same dentition; (3) to describe mineralization process and enamel maturation in insectivorous dentition; (4) to describe late odontogenesis in molars of insectivorous dentition and its interlacing with enamel maturation, and how they come to occlusion.

The proportion of minerals in the soil of selected layers in the region of Stropnicko
 KOTOUSOVÁ, Zdeňka
My work targets the change in content of the organic soil karbon and basic cations in relation to changes of area usage and agricultural management of the chosen special {--} interest places of Stropnicko. In the monitored period from 2001 till 2007, the soil organic mass markedly fell off. The greatest decline was in the forest ecosystem in all researched basins. Decline of organic soil karbon content was also found on permanent grass growth, but it was much less than in the forests. On the contrary mild improvement turns out on the arable land. Next pH value of soil leach was monitored. The greatest change was shown in the forests. The greatest increase of PH value was at the area of Pasecký potok. In other basins, expected Veverský potok, pH value increased too. On the contrary, there is decline of pH value on the permanent grass growth and arable land . There were not statistically great advancements between 2001 and 2007 in the soil mineral reserve, especially of the basic soil cations. The significant decline of sodium is the exception. I have suggested steps that lead to the steady way of farming in the agricultural foothills. I have recommended to increase supplied barnyard manure into arable land, the optimalization of cow units for pasture area and the gradation of the forest communities to deciduous, eventually mixed stands, according to the vegetation levels.
