Elektrický ohradník jako nástroj ochrany lesa před škodami divokým prasetem (Sus scrofa)
Hvižď, Filip
The study was dedicated to investigating the use of an electric fence as a possibility to regulate the spatial activity of wild boar and the related protection against damage caused by this species. The research was carried out in the Moravský Krumlov nature reserve, where an electric fence was built and its effectiveness in controlling the movement of wild boars was monitored. Cameras were installed to collect data. Out of the total number of 663 contacts of wild boars with cameras at the time when the electric fence was triggered 75 of them were recorded inside the fenced area, which is less than 12 %. After analysing the obtained records, the reaction of the wild boars to the fence was evaluated. During a more detailed analysis of the obtained data, it was found that the most common reaction of an affected adult boars is to run away from the fence (more than 60 % of cases), on the other hand, breaking through the fence was minimal. Furthermore, the variability of the reaction to the fence was determined in time, when the boars did not perceive the fence at first, but with the passage of time boars began to maintain a distance.

Effect of Trampling on the Vegetation of Dry Grasslands
Vacková, Nikol ; Horčičková, Eva (advisor) ; Husáková, Iveta (referee)
1 It has been proved that the effect of vegetation trampling (Anthropogenic and animal) significantly changed. The aim of this study was to gather available information of these changes and effects of secondary factors, particularly focusing on the dry-grasslands (Festuco-Brometea). Vegetation on trampling disturbed areas is already much lower, it has less vegetation cover and there is more bare soil. On the bare soils increases temperature and greater evaporation of water. Due to changes of climatic conditions of microhabitats the diversity of species is changing. Vegetation is not changed only on the trampling trails, but also in the surrounding area, up to a distance of 2 meters from the trail. Most vulnerable to trampling and most susceptible for changes in vegetation are moist habitats, the most resistant type of vegetation is thermophilic dry-grasslands. The behavior, abundance and intensity of browsing animals have also effect on vegetation changes. Animals during their browsing vegetation disperse seeds and plants spread beyond their natural occurance.

Perception of the human disturbance by ungulates in the wild and in the captivity
Šťastná, Tereza ; Komárková, Martina (advisor) ; Frýdlová, Petra (referee)
The relationship between ungulates and humans has been evolving ever since the first predator's interaction with the prey, leading to the current domestication. The behavior of ungulates differs based on the human disturbance. The goal of this thesis was to compare the reactivity to humans of selected species in nature vs. in captivity and determine its correlation, inter or intraspecific. The thesis indicates reactivity to humans of specific species of ungulates (donkeys, horses, reindeers and goats). Following reactions were chosen for comparison: vigilance, alert distance, flight and avoidance distance. There are several acting factors like previous experience with humans, habituation, group size or season. With group size, the vigilance decreased, which was proven with donkeys, reindeers and goats. The behavior differed based on the season by resources availability, offspring's presence in herd (higher vigilance) or rut (lower vigilance). In captivity, there were less human contact avoidance, while the experimenter was known. Based on researches, ungulates tend to avoid humans more in nature, than in captivity. Sources claim, that among chosen ungulates, the most vigilant in both nature and captivity are reindeers. Further researches could later consider the human perception according to the...

The role of trampling trails of wild ungulates in the vegetation of semi dry grasslands
Vacková, Nikol ; Horčičková, Eva (advisor) ; Mládek, Jan (referee)
Animals affect vegetation in many different ways. In this thesis we have focused on the impact of wild ungulates in the Czech Republic (wild boar, red deer, sika deer, roe deer). These animals affect vegetation with grazing, defoliation, defecation, browsing and other activities. We decided to study the effect of browsing. The animal trails are formed by browsing animals. These trails can be easily recognized due to long-term browsing. They are especially caused by trampling, which affects vegetation in many ways. The aim of this study is to determine how the vegetation of dry-grasslands (Festuco-Brometea) responds to long-term trampling caused by wild ungulates. We found that on trails, there is more bare soil, less litter and lower vegetation. In its close proximity, there is also a slightly greater diversity of plants than in control samples. Species like Plantago media which are growing straight on the trail, have adapted to trampling, while smaller shrubs (eg. Rubus, Crataegus), start to appear 2 meters from the trail. Using Ellenberg values, we found out that heliophile species, which grow on the trails and the species in control samples need more moisture and more nitrogen. Using the experiment with transplanted blocks, we learned how vegetation responds to the introduction/exclusion of...

Between-year dynamics of carnivores and ungulates in the Czech landscape
Schnebergerová, Adriana ; Pyšek, Petr (advisor) ; Sedláček, František (referee)
It is important for the ecological management of wildlife populations in the Czech Republic to know the composition of species in individual habitats. This will allow predictions on the reactions of wildlife based on evolving changes that will occur sooner or later in these habitats due to human activity and natural change of our environment. Camera traps are a powerful tool of the 21st century with which we are able to observe wildlife without major interventions in their lives. With the right experimental design, camera traps allow us to find out details about wildlife life such as their distribution and habitat preferences, population structure, and their behavior. In this work, I used camera traps to determine the species composition of two groups; ungulates and carnivores in different habitats. This thesis analyzes the habitat preferences and hepls to find out to what extent the spatial patterns of occurrence on these two groups are in the monitored habitats over the course of a couple years. Data collection took place from June 2015 to May 2017 in the Central Bohemian Region northeast of Prague. Despite the fact that the area is densely populated and agriculturally exploited, I was able to capture four species of ungulates and nine species of carnivores on a total of 73 camera traps in this...

Carnivores and ungulates in Mid-European landscape
Podhůrská, Marie ; Horáček, Ivan (advisor) ; Hart, Vlastimil (referee)
Carnivores and ungulates in Mid-European landscape Abstract The paper provides a brief survey of abundance status and population trends for most species of large mammals distributed in the Czech Republic. Abundance dynamics during past decades is discussed based on hunter statistic records covering both yearly data on hunting bags and standardized accounts of spring abundance of game animals from gamekeeper's evidence. It is documented that most of the species including regularly hunted ungulates, most of mesocarnivores and currently expanding species (racoon dog, racoon) are undergoing fluent population density increase contrasting with decrease of abundance of smaller to medium sized forms (hare, rabbit, marten, polecat). The respective data suggest that recently the community structure of large mammals has undergone considerable rearrangements. The monitoring of such phenomena is worth of a serious zoological research. The paper discussed methodological issues for such studies with particular attention to techniques of monitoring with aid of automated camera traps. Relations of the recorded faunal changes and landscapes rearrangements during past decades are also discussed. The paper is supplementing with a brief summary of two-year camera trap study in Brdy Mts. Key words: carnivora and ungulates,...

Vliv kopytníků na zemědělskou a lesnickou produkci v kraji Vysočina
Dvořáková, Petra
This diploma thesis deals with the problems of damages caused by ungulates on forest and agricultural lands in two model areas in Vysocina region. The first part provides the theoretical background about damage by game, protection against damage and quantification of damages. In the second part the data on the damage of plots and numbers of game animals for the years 2015 and 2016 in hunting areas are processed. The data are processed in charts and tables and the impact of selected game species is then evaluated. The greatest damage on forest land in the area is cause by browsing by roe deer. On farmland, the greatest damage is caused by the population of wild boar on the permanent grassland. In the investigated area, the total damage caused by game is low. At the end of the thesis the results and suggested possible measures are summarised.

Trypanosomes of ungulates with emphasis on Europe
Brotánková, Anna ; Rádrová, Jana (advisor) ; Dvořák, Vít (referee)
Trypanosomes are veterinary and medically important parasites causing serious diseases and significant losses in livestock farming. Two subgenuses of trypanosomes were identified from ungulates in Europe. Trypanosoma evansi and T. equiperdum, flagellates of the subgenus Trypanozoon, could cause fatal infections to their hosts. Other Trypanosoma theileri, T. cervi, T. stefanskii, T. melophagium and T. theodori were discovered in European ungulates from the second subgenus Megatrypanum. These trypanosomes are common parasites in Europe, especially Trypanosoma theileri and T. cervi. On the other hand, T. evansi and T. equiperdum are occuring rather sporadically. Trypanosomes of the subgenus Megatrypanum are less significant because their lower medical and economical impact. They are generally apathogenic and so do not cause any clinical signs. Both morphological and phylogenetic informations of European trypanosomes are summarized in this work as well as details about their pathology, vectors and records of evidence in Europe.
