Home range activity of the Brown Bear (Ursus arctos) in ZOO
Vojáčková, Jana ; Řezníček, Jan (advisor) ; Andreska, Jan (referee)
This dissertation deals with monitoring of European brown bears behavior (Ursus arctos arctos), namely of males Pišta, Miky and Honzík and of female Eliška in zoological garden in Plzen in spring 2012. Behaviour of all European brown bears is for better clarity presented in the form of tables and graphs. The dissertation includes overview of all kinds of ursine (size, environment, food and reproduction). Key words: bear, hibernation, bears activity

Interakce mezi početností a distribucí srnčí zvěře a skotem na pastvě
Horák, Vojtěch
The purpose of investigation was to determine the relationship between the abundance and the spacial activity of roe deer (Capreolus capreolus L.) and cattle grazing in the area of interest in southern Bohemia, consisting of three mixed hunting grounds. The selected suitable locations where cattle grazing took place were compared with sites where cattle grazing did not take place. The abundance and the distribution of roe deer in these locations was determined by counting the faecal pellet groups in total of 160 disposable strip transects (FSC - with no cleaning) and by direct observation during 80 countings. The results revealed a lower abundance of roe deer and a change of its space activities in areas with grazing cattle compared to sites with no grazing meadows.

Spatial activity of birds and methods of its continuous monitoring
Havelka, Jan ; Sedláček, Ondřej (advisor) ; Kauzál, Ondřej (referee)
The aim of this work was to collect current knowledge of avian spatial aktivity focusing to its internal structure, using modern telemetry devices which allows continuous monitoring of small animal species. In the light of these new methods, avian home ranges seem to be more dynamic structures, changing during diurnal and nocturnal acitvities, breeding cycle, age, sex and social statut of a bird. Thanks to detailed radiotelemetry we can observe even secretive animal behaviour and its characteristics in three dimensions. Continual monitoring allows us to study migration in a detailed way, its influence to other parts of their annual cycle and to asses migration connectivity. In future these new information should be used for targeted conservation of endangered species.

Scaling of spatial activity in bats
Křemenová, Jana ; Lučan, Radek (advisor) ; Storch, David (referee)
2 ABSTRACT The degree of spatial activity, especially the home-range size, is one of the basic biolog- ical characteristics of animals and whether it has enough resources is crucial for the survival and reproduction of the individual. Therefore, it is not surprising that many studies trying to make clear the effect of various ecological and morphological variables and explain the varia- bility of space activities. Bats are a group of mammals, for which until recently, existed only few information about their spatial activity. However, due to the miniaturization of technology and the use of radiotelemetry amount of information rapidly increasing. The aim of this study was to assemble the most complete information about the home- range size and foraging distance of bats and analyze the effect of variables that can influence the spatial activity. From published papers I collected data on 106 species representing 8 fami- lies. The influence of 6 variables (weight, wing loading, aspect ratio, food specialization, colony size, primary productivity of environment) on home-range size and average foraging distance of bat was analysed by phylogenetic regression (PGLS). The best predictor of the home-range size is the primary productivity of the environment, food specialization and body size. The best explanation of...

Effect of supplementary feeding on the spatial activity of red deer
Kilhofová, Blanka ; Bejček, Vladimír (advisor) ; Otakar, Otakar (referee)
Military Training Area Hradiste occupies the entire central part of Doupov Mts. Restrictions on public access and unified huntsmen management of the large area
gave rise to a unique habitat of red deer. There is a series of studies conducted on game populations, including research of spacial activity of red deer using GPS telemetry. Telemetry data were used to evaluate the effect of the feeding device on the spatial activity of red deer. This impact was affected in the observational period by the mild winter, yet the effect on the spatial activity is apparent. Males are much more active during feeding period than females and their relation to feeding equipment is also higher than in females.

Spatial activity of wild boar in the Doupov Mts.
Šácha, Zdeněk ; Ježek, Miloš (advisor) ; Otakar, Otakar (referee)
The aim of the bachelor thesis is to evaluate the spatial activity of wild boar (Sus scrofa L.) in the Doupov Mountains. The Doupov Mountains are unique landscape for research of free living wild animal adaptation on environmental changes and reaction on human pressure. There are military area, where the entrance for public is restricted. The area cover more than 35 000 ha and there are uniform system of forest, agriculture and hunting management. Therefore we can study easily the impact of hunting there.
Data were collected by GPS telemetry from 3 females and 1 males of wild boar. We used GPS telemetry for tracking wild boar during the December 2013 and December 2014. We analyzed the tracks of wild boar during the season, the size of home ranges, and the activity during 24 hour period. The results shown on significant nocturnal behavior by wild boar male during whole year, and by wild boar females during autumn, winter and beginning of spring. But the activity is changing after the birth of juvenile, when the females are active during the daytime. The bachelor thesis results provided very interesting information from wild boar ecology, but the study should be continue due to short time of GPS observation.

Vliv pastvy skotu na výskyt a prostorovou aktivitu srnčí zvěře
Horák, Vojtěch
The topic of this thesis deals with the influence of grazing cattle on the incidence and spatial activity of roe deer game. For the purposes of this work were selected territory in southern Bohemia in the three associations the hunting grounds. The field investigation was conducted by the method of direct counting of the advantageous positions in the pasture and correlation surfaces from the beginning of the grazing and at regular intervals during it until its end. The result of the work is the assessment of the various factors operating on the roe deer in these locations and a proposal of measures that could mitigate the effects of the negative impact of grazing cattle on the hunting management of roe deer to the game.

Study of spatial activity of small mammals inhabit isolated forest draws in agricultural landscape with a focus on the use of surrounding food sources.
HAVLOVÁ, Jitka
Habitat fragmentation during 50s of 20th century caused decrease in food resource availibility for many small mammalian forest species. Despite all of the changes, those species managed to adapt to it - one of the adaptation mechanics has been migrating into agricultural areas. The main aim of this study was to describe the spatial activity of Apodemus sylvaticus and Myodes glaerolus inside two forst patches and compare it. My next aim was evaluate the significance of agricultural areas nearby the researched forest patches. One part of this was even the comparison of different marking techniques used for rodents in field. Data describing movement activity of researched species were collected using capture-mark-recapture (CMR) As expected the data differ - Greater mobility was found in A. sylvaticus, the M. glaerolus preffered to stay inside patches with larger vegetation cover. The raids into surrounding patches differed even in those two researched forest sites. In site "Samota" A. sylvaticus showed greater movement distance, however in "Hejtman" it were M. glaerolus expressing greater movement ability. Theirs movement were directed inside clover field. Both species of Samota site ventured into patches with dense plant cover, perhaps to minimise the risk of predation. The best method of marking proved to be the clipping the rodents ears with tags. As the next more efficient I would choose the ear-clipping.
