Changes of volume activity of radon in soil gas in dependence on the meteorological parameters
Hrušková, Gloria ; Matolín, Milan (advisor) ; Jáně, Zdeněk (referee)
This work engages in radon in soil gas, measuring its volume activity and atmospherical influences on its volume activity. Atmospherical (or meteorological) influences are a pressure, temperature and moisture of the air, wind and its velocity, a condition of the sky and a rate of precipitation. The measurement results from the period 2000-2012 done by the Charles University in Prague, Faculty of Natural Science (The Institute of Engineer Geology, Hydrogeology and Applied Geophysics, Department of Applied Geophysics) in the radon comparisoning areas Cetyně, Bohostice, Buk were used for the assessment.

Fenologie lesních dřevin v měnících se podmínkách prostředí s ohledem na výškový gradient
Vránová, Kristýna
This thesis if focused to assessment of phenological characteristics of European beech (Fagus sylvatica L.) and European larch (Larix decidua Mill.). The observation was performed in two mixed forests of the same age situated at different altitudes 300 and 600 meters, respectively. Main meteorological variables were measured on both sites in order to describe the mezoclimate of the site. Observation of phenological phases was conducted in regular intervals twice a week. The results of the study confirm the strong dependence on both air and soil temperature. Collected data show the importance of temperature at the end of winter and early spring. Starting time of spring phenological phases depends on reaching of species specific temperature limits. The highest variability among individual years shows the time of beginning of budbreak. The temperature increase results in earlier beginning of spring phenological phases as well as shortening of their duration. For similar reason, also autumnal phenological phases are shifted towards the winter time. This fact causes longer vegetation period at the expense of winter dormancy.
