Population density of the roe deer (Capreolus capreolus) in Hartmanice district (SW Bohemia, Czech Republic)
Večeřová, Petra ; Červený, Jaroslav (advisor) ; Rohla, Jan (referee)
This diploma thesis was based on frequently discussed topic of population density in hoofed game. The monitored area is in the south-west of Bohemia, in Hartmanice. The greater part of the territory extends into the conservation area and a smaller part od the Šumava National park, with this work focusing on the population density of roe deer. To determine population densities, two methods were used, one direct method and one indirect method. For the direct method, a census method was used for the roe deer from a high seat and the indirect method, a method of counting droppings was used on a sample of regulary cleaned surfaces. Counting was carried out on transects of 200 m2 (100 x 2 m) or (50 x 4 m). The present results indicate that the population of roe deer is seeing a long downward trend. Most roe deer prefer the brushwood at lower altitudes, at an altitude of 525 to 650 m above sea level (asl), with less occuring in the positions of the altitude of 950 to 1125 m asl. The habitat least preferred by roe deer was forests aged 81 years and older.

Effect of hunting pressure on red deer activity
Rohla, Jan ; Ježek, Miloš (advisor) ; Obleser, Petr (referee)
In this work, I dealt with the impact of hunting pressure on the activity of red deers (Cervus elaphus) in Doupov mountains. The main goal was to find out, whether intensive killing will change the activity of deers, and also hinds. Evaluated data should be useful for easier reduction of these animals not only in Doupov Mountains. Numbers of deers have been very high in the last few years and it would be necessary to achieve effective reductions, which would reduce the population to a tolerable limit. That should contribute to decreasing animal causes in forests and agriculture crops. Decreasing the numbers of deers should also lead to improving the quality of this spiecies not only in terms of trophies, but also the overall physical condition. It turned out that the activity decreased significantly during hunting.
The reduction of activity began basically with the sunrise and ended in the sunset. For most individuals the activity increased in the night hours. In both July and August it turned out that there is a significant difference in activity among both day and sunset as well as day and night, while the lowest amount of activity was in the daytime, and in the sunset it has increased significantly. The highest activity was basically at dusk.
From these results we can say that when comparing the two periods, the significant activity is mainly in the evening and night hours.
