Analýza chování prasete divokého na vnadištích
Pavelka, Martin
This bachelor thesis is dealing with the behaviour of wild boars on baiting places. The research was conducted on hunting areas in northern Moravia, district Bruntál. Not only in the chosen area, but in the whole Czech Republic is dealing with the problem of overpopulation of wild boars. The observation took place using trail cameras, which took photos of baiting places. On these places was scattered feed, which was weight before. Times of arrivals and the number of wild boars were found from trail camera photos. In the next step was calculated the average amount of feed, which can wild boar consume in one hour. From ascertained data was recommended maximum amount of feed, which will be enough for periodical arrivals of wild boar on baiting place and thus reduction of overpopulated wild boars.

Analýza poměru pohlaví a věkové struktury vybraných populací prasete divokého a zhodnocení vlivu loveckých aktivit
Svoboda, Tomáš
In three locations in the Czech Republic an analysis of sex ratio and age structure of selected populations of wild boar was conducted in order to assess age and sex structure of hunted game. The analysis was conducted in 2016-2018 during organised hunts without distinction of sex and age. Altogether, 665 wild boars were assessed, out of which 384 were females and 281 males. Sex was identified with each head, so was their age – according to teeth development, and their weight – using scales. According to the results, the sex ratio is deteriorating with growing age, leaving more females; examined locations show poor structure of game from the point of view of both age and sex. Although farrowing was at its highest in spring, it is happening all year round.

Výskyt plicní červivosti u prasete divokého v České republice
Poulíčková, Kateřina
A study of endoparasite Metastrogylus sp. causing lungworm in the wild boar (Sus scrofa) population was conducted between November 2016 and December 2017. Samples were collected from 13 selected localities in the Czech Republic. Using the partial helminthological autopsy of lung samples and coprological method by McMaster counting technique the prevalence and incidence of endoparasite Metastrongylus sp. were examined. 104 samples of lungs and excrements were tested by these methods. Detected prevalence of endoparasite Metastrongylus sp. was 94% of the examined lung samples. Comparison of infection incidence among selected localities, age classes, weight categories and sexes were also evaluated in this bachelor thesis.

Inventarizace škod prasetem divokým na kulturách lesních dřevin
Glogar, Jan
Recently, we have increasingly encountered damage to wild boar on planting. Whether the seedlings are plucked out or scraped off, or if the overground or root pack is damaged, these can be fatal for next growth. This work tries to find out what information is currently available about the issue, how frequent the problem is in the Czech Republic, which experiences of people who have met these damages and how to be successful in protection. Finally, the obtained data are evaluated and a set of recommendations is formulated to minimize this problem.

Analýza struktury a prognóza vývoje populace prasete divokého v ČR
Krátký, Matouš
The topic of this thesis is divided into two main parts. The first part deals with the population of the wild boar in the Czech Republic aiming to analyse its structure and predict its development. It was necessary to carry out various calculations according to Kolář (2014) methods to produce this work. The second part of the thesis deals with the issue of age estimation of hunted wild boar with a focus to Mitchell's methods and its practical use. For purposes of this work these methods were applied to statistically representative sample of wild boar's lower jaws, while using a new ways of visualisation of the dental cement layers.

Evaluation of mass game hunted in selected hunting grounds in the area of Konstantinovy lázně
POKORNÝ, Radek
Free-ranging population of sika deer, roe deer and wild board in micro-region "Konstantinolázeňsko" in Czech Republic, has been determining dressed body weight, whole body weight, weight of head, weight of limb and weight of internal organs (heart, lungs, liver, spleen and kidneys). The correlation between all weights was calculated. During the research was determined mean weight between whole body and dressed body. In this study the dressed mean weight of sika deer was 74,03 % of the whole mean weight. For wild board the mean dressed weight was about 78,56% of the whole weight and for roe deer mean it was about 76,66% of the whole weight. Obtain weight has been statistically analyzing of ages, sexuality, seasonal variation. For both sexuality of wild board was statically proven that body weight is increasing with age. For sika deer calfs was statically proven that body weight was higher if the calf was shoot after 15. 1. then cals was shoot before. For sika deer with out age difference was statically proven that sika males had higher body weight than sika females. Other types of statistics are listed in the document.

Effect of wild boar on dry grasslands
Horčičková, Eva ; Vojta, Jaroslav (advisor) ; Hejcmanová, Pavla (referee)
The study was focused on disturbances by wild boar (Sus scrofa) and their impact on vegetation of semi-dry grasslands (Festuco-Brometea) dominated by Brachypodium pinnatum. The research was conducted in military area Hradiště in hilly region of the Doupovské hory. Wild boar rooting activities is main source of disturbances regime in this abandoned, previously agricultural area. The vegetation of artificial small scale soil disturbances was compared to undisturbed control plots and vegetation of natural disturbances by wild boar. Experimental plots were established during the summer 2007. Consequently a vegetation survey of these plots was carried out and soil was mechanically disturbed. Succession on disturbances was annually monitored. The surrounding natural disturbances were also mapped three times a year as a potential source of diaspores and to assess their frequency and effect on the landscape level. The list of species in the 2m, 4m and 16m distance from the experimental plot was also made. Results: Disturbances by wild boar increased species diversity and spatial heterogeneity of semi-dry grasslands. There were some species found on experimental plot, which were present not in the surrounding matrix. Most of them belong to hemicryptophytes and species with long-term persistent diaspores. Presence of...

Trapping systems on wild boar - techniques and utilization
Hradilová, Adéla ; Ježek, Miloš (advisor) ; Mrkvičková Kořanová, Diana (referee)
This thesis addresses the first part of a literature review on the types of traps for wild boars and the possibility of running them. Also in this section is also included Czech legislation related to the topic of trapping wild boars.
The second part is more catching device is placed in a hunting Blazice - Sovadina, which is currently undergoing a wild boar. The cage will evaluate the success of the capture. Catching devices have been installed in various parts of the hunting grounds. Predominantly located in agricultural crops. Evaluation will be well used in baits.

Towards a better understanding of ungulate diets: a methodological approach
Holá, Michaela ; Červený, Jaroslav (advisor) ; Stádník, Luděk (referee)
Populations of European ungulates have grown substantially over recent decades, resulting in considerable environmental and socio-economic impacts. Availability and quality of natural and supplemental food sources are among the main factors driving their population dynamics. Detailed knowledge of feeding strategies of management-targeted species is therefore of primary importance for their successful management. Over time, methods to study the feeding strategies of animals have also evolved considerably but each has its advantages as well as limitations. This doctoral thesis uses a combination of traditional methods (i.e. stomach content analysis) and novel methods (i.e. stable isotope analysis, near infrared reflectance spectroscopy) to achieve a better understanding of feeding strategies of two important ungulate species (i.e. wild boar and red deer) in the Czech Republic, where their populations are on the rise and supplementary feeding is rampant. Next, this dissertation aims to introduce and to establish a basis for these novel methodological approaches for the study of free-ranging individuals. In this respect, it also addresses methodological issues related to their application in this field.
The diet composition of wild boar was investigated by examining stomach contents in order to identify their dependence on food resources of human origin (i.e. agricultural crops and supplemental foods). Foods of human origin were the dominant diet type and constituted the bulk of the diet of wild boar throughout the year. A necessary prerequisite for application of stable isotope analysis is the trophic discrimination factor (i.e. systematic difference between the isotopic composition of the consumer tissues and that of the diet), which was experimentally determined for stable carbon and nitrogen isotopes, the two most commonly used in ecology, in hair tissue of wild boar and red deer. Furthermore, possible sources of variation (such as sex, age, body weight, and lactation) on isotopic discrimination were investigated. The results of the experiments provide a starting point for the successful use of stable isotope analysis in field studies on wild boar and red deer. Finally, application of near infrared reflectance spectroscopy was proven to be useful in measuring faecal indices of food quality for red deer. The results of this thesis will contribute towards efficient management of wild boar and red deer in the Czech Republic.

Zhodnocení distribuce trusu prasete divokého v lesním prostředí jako podkladu k odhadu jeho početnosti
Drimaj, Jakub
In study area near the town of Jihlava, formed by two forest hunting grounds, was realized a survey of distribution of droppings of wild boar (Sus scrofa L.) in order to verify the validity and improvement of dung census methods to estimate wild boars density in the forest environment. Counting of droppings was performed after the fall of the snow cover (before the growth of vegetation), on uniformly spaced lines (in strip transects), set by using geoinformation system and GPS devices. Each faecal pellet group (FPG) was geographically focused (GPS coordinates) and comprehensive database of 3 442 FPG was analysed over the digitized map data of Lesy ČR, s. p. (LHP). The average FPG density in the forest environment was 143,4 FPG.ha-1 and wild boar abundance was estimated at 19 individuals.km-2.
