GPS telemetry and activity measurement focused on even-toed ungulates (Artiodactyla)
Peterka, Tomáš ; Bartoš, Luděk (advisor) ; Komárková, Martina (referee)
GPS telemetry is a recently expanding method for research on most animal species. It provides automatical scanning of position and related data on large distances and often on large temporal scale. The research studies has changed dramatically during the development of this method. Experiments using this technology deal with scanning of incidence, management and species conservation, activity pattern of controlled animals, estimation of behavior in various scales and so on. Activity sensors which are often included to GPS collars serve for determination of behavior of monitored species. In this thesis there are summarized basics of VHF and GPS technology. In available articles of great terrestrial mammals like even-toed ungulates (Artiodactyla) and marginally also bears (Ursidae) we show possible application of GPS technology for activity measurement, methods, restrictions and results of experiments. At the end we introduce experimental approach for activity measurement of red deer (Cervus elaphus) and results of the pilot study.

Effect of hunting pressure on microhabitat preference of red deer in the Doupov Mts.
Křivan, Lukáš ; Ježek, Miloš (advisor) ; Stanislav, Stanislav (referee)
This master thesis is focused on GPS telemetry of red deer (Cercus elaphus) in the environment of the Doupov Mountains in the Military training Hradiště. In the first part of the thesis are solution of introduction to general issues preferences and the occurrence of red deer and other related ungulates. The second part of the thesis is focused on my own research.
The Positional data monitored hind Dorothy was collected in the period 1. 7. 30. 3. 2014. The aim was to determine, if the time hunting have to influence to microhabitat preferences on the hind of red deer and if the selection of posts are accidental or is influenced by the characteristics of the post. The Research conducted of data inventory from GPS using collar and of data, which arised laser air scanning the surface (technology LiDAR). For comparison and finding the preferences of the hind was created the network accidental comparative points. Field exploration and LiDAR technology consider the dependence of the average height of vegetation around of Dorothy positions the period of the year and the time of day. Data was evaluated ANOVA for the non-parametric data distribution (Kruskal-Wallisova) and the program Microsoft Excel. At each station has been carefully identified information about the location including visibility of the hunting-game device and height of stand.
The results indicate that the average height of the vegetation was at the stands searched by the hind of red deer during a sunrise and a day. The lowest was in night and at sunset. The hind of red deer prefer, in hunting time during the day, thick scrub and during the night more open spaces with larger views properties, where she actively looking for food. The most preferred visibility at the time of hunting and off time hunting was to the eastern direction. The most least preferred visibility was always to the western direction. Minimum presence of the hunting-game device is in the time of hunting during at the day and sunrise, maximum at night. This behavior was probably caused increased hunting activity.
The results of the thesis may be used in forestry management, for forest protection and by planning of hunting management of the red deer populations.

Habitat preferences of red deer and sika deer in the Doupov Mts.
Löwe, Radim ; Ježek, Miloš (advisor) ; Husinec, Václav (referee)
This master thesis is focused on GPS telemetry of red deer (Cervus elaphus) and sika deer (Cervus nippon) in the Doupov Mts., the Czech republic. Positional data from 14 red deer does and 2 sika deer does was collected during the study period of April 2013 to February 2016. The main aim was to determine habitat preferences of does with the use of the very precise vertical differentiation of vegetation created by air laser scanning of the surface (LiDAR technology). The study examines the dependence of the average maximum height of vegetation nearby positions of does on the time of year and time of day. For the evaluation was used two-way factorial analysis of variance. The highest average height of the vegetation nearby does was found during the day and the lowest during the night. Does of red deer and sika deer occurred in open habitats particularly at night, where they were actively seeking for food and more closed habitats with higher vegetation during the day, where they could hide themselves. Focusing on a period of the year, the height of vegetation in the summer period without hunting was significantly lower than in the summer period with hunting. This could be caused by starting hunting season but also it might be a response to reduced quality of available grass by aging. The two does of sika deer were treated individually. Significant differences were revealed between both does. However they both were occupying habitats with the lowest height of vegetation at night during the rut season.
The gained results can now be used to supplement information about ethology of red deer and sika deer. The comprehensive knowledge of ethology can be directly used in the management of these two species, particularly for hunting efficiency and subsequent reduction of their population numbers, particularly in the case of sika deer. However these results can be directly used in forest management in active protection of forest stands against damage by wild game.

Habitat preference of red deer and sika deer in the Doupov Mts.
Silovský, Václav ; Ježek, Miloš (advisor) ; Zdeněk, Zdeněk (referee)
The bachelor thesis is focused on habitat preferences of red deer (Cervus elaphus) and sika deer (Cervus nippon nippon). The objective of study was to determine, which types of landscape the red deer (Cervus elaphus) and sika deer (Cervus nippon nippon) prefer during the year. Study area is located in northwest Bohemia in Doupov mountains. Data were collected by GPS telemetry from 13 stags and 13 hinds of red deer, and 6 stags and 2 hinds of sika deer during the days between 19th September 2010 and 8th February 2015. From GPS telemetry we received a total of 176982 red deer pozitions and other 38932 sika deer pozitions. Analyzed home ranges have shown main preferences of male and female red deer to shrubbery and natural grasses. Males of sika had main preferences to shrubbery and mixed forest during the year. Sika females have preferred shrubbery and natural grasses. The bachelor thesis results provided very interesting information of red and sika deer ecology and could be used in future game management or when creating a new emerging legislation, especially in the area of minimum hunting grounds quantities.

Microhabitat preference of male red deer in the Doupov Mts.
Vlasák, Tomáš ; Ježek, Miloš (advisor) ; Kušta, Tomáš (referee)
My work engages problems of microhabitat preference of male red deer (Cervus elaphus). Location of research was occured in the Military Training Area Hradiště on the forest administration district Dolní Lomnice in the Doupovské Mts. Research was conducted using a GPS device. The first part of bachelor thesis is focused on literary analysis as a description, biology, ethology and damage by red deer on the forest stands. The second part of bachelor thesis is research itself. Home range size was calculated from winter and summer habitats. Monitored male red deer prefered visibility to the south. The lowest visibility was found to the west. During the day occurrence of hunting facilities is minimum in winter and summer periods. Greater occurrence of hunting facilities was only found in the night and morning time in the winter. Collected data were analyzed using graphs and tables, which are situated in the final part of this bachelor thesis.
