Trophic ecology of the greater mouse-eared bat (Myotis myotis)
Bendová, Barbora ; Andreas, Michal (advisor) ; Bartonička, Tomáš (referee)
In 2012 it was observed foraging ecology of the three males of greater mouse-eared bat (Myotis myotis), inhabiting individual roosts in the interior of road bridge near Bernartice, and the nearest nursery colony of the same species in the village Senožaty (district Pelhřimov). In the period April to September in Senožaty were made 14 collections at intervals of approximately 14 days and in the bridge near Bernartice at similar intervals were made 8 collections from each male in the period from May to September. From each collection were subsequently been analyzed 20 samples (pellets) by the traditional method of preparation of faeces. Overall it was from all the bats analyzed 760 samples, of which 280 from the nursery colony and 480 from males. Based on the analysis was found diet composition of individual bats and of the colony, where the overall character of the trophic niche of the greater mouse-eared bat, seasonal dynamics in it's diet composition, sex differences and individual differences between males were observed. From a point of view of it's hunting strategy the greater mouse-eared bat showed itself as a ground gleaner, in whose diet were dominated larger Coleoptera, of which the predominant component were large, flightless, mostly forest Carabidae, adding medium and smaller species of...

Evaluation of the natural value and ecosystem services of natural biotops in the intensively managed agricultural landscape
HAVEL, Jaroslav
My thesis is focused on valuation methods intensively used agricultural landscapes according to the importance of near-natural habitats in terms of their natural values and ecosystem services. This is done at four sites using pitfall traps, where there was a catch beetles (Carabidae). To evaluate the data I used indicators such as the Shannon index serenity. Procedures for calculating the ecological value of the area and the ecosystem services provided I processed according to the proposed method Seják et al., (2010). Rating I performed by BVM (,, habitat valuation methods "). Replacement cost method I used for the calculation of ecosystem services.

Vliv pěstování energetických rostlin na biodiverzitu
DVOŘÁK, Jan
The thesis is focused on the cultivation of energy crop in the Czech Republic and their potential use as renewable energy sources. It describes energy plants grown for the production of liquid fuel, biogas or direct combustion. Furthermore, there is an emphasis on environmental aspects of cultivating these plants. Especially erosion risks of the land on which energy crops are grown, is also evaluated. There is described the species diversity in crops focusing on weeds and ground beetles as bioindicators environment. Part of this work is elaboration a questionnaire with subjects that deal with the cultivation of energy plants. In the questionnaire, there is observed total area and the percentage of types of energy and other cultivated plants. The subjects were also asked about new kinds of energy crops, and whether they planned their growing in the near future.

Biodiversity of model agroecosystems on the ecological farm in the vicinity of České Budějovice (Lišov)
POJSL, Miroslav
Epigeic beetle communities were studied on three agroecosystems with different crops grown. All three agroecosystems were located in the vicinity of Ceske Budejovice (Lišov). The first eco-agroecosystem was alfalfa field. On the second one was meadow. The third eco-agroecosystem was permanent grassland. The agroekosystems differd not only in crops but also in agrotechnical operations during the capture. For all agroecosystems was for capture of the organisms used method of pitfall traps. Subsequently, those organisms have been studied. Then was studied the measure of human impact on the biodiversity of species of different ecological groups found in these locations.

Ground beetles (Coleoptera: Carabidae) as bioindicator of natural and anthropogenic habitats
SPITZER, Lukáš
The ground beetles are one of the most worthwhile model groups of organisms for the indication of quality of environment due to their advantages such as simple identification, well known ecology of most species and described distribution. In this thesis I present the suitability of assemblages of ground beetles to evaluate the conservation value in two types of environment: (1) open forest in medium and lower altitudes, (2) post-mining biotopes as quarries and black coal dumps. I also discuss possible limitation of ground beetles as valid bioindicators and I recommend multi-taxonomical approach in ecological studies.

Cultivation of the fast growing plants for energetic purposes and its effect on biodiversity
REKTORYS, Jan
A research regarding the today´s energy sources has been conducted. Different kinds of fast growing herbs and timber were evaluated, considering their advantages and disadvantages, respectively, in terms of their habitat and the volume of biomass. The indicators of anthropogenic influence over particular cultures were defined with the help of invertebrate animals. Epigeic beetles were indicated as perspective indicators of human impact. As a result of the study, it appears that the biggest volume of biomass can be found in a willow clone S ? 705 (15 tons of dry matter ha/year in the first rotation period) and speaking of herbs, that is in invasive Giant Knotweed (60 tons of dry matter ha/year). The least demanding, in terms of growing, are Spear Saltbush and goosefoot.

Communities of epigeic beetles (Coleoptera) in the different types of green belts in fields
ŠEBÍK, Jakub
SUMMARY The assemblages of epigeic beetles were studied in various types of agroecosystems in the submontaneous area of Novohradske hory (South Bohemia, Czech republic). The research took place in years 2009 and 2011. There were sown various types of crops, in the target places, on which were established either biobelts (research 2009) or permanent green belts with trees and shrubs (research 2011) in past. The aim of the study was to assess, whether or how these landscape structures influence epigeic beetles. The datas were gathered by sampling ground beetles with ground traps. The collected material was put then through identification and this was the base for assessing the parameters of landscape structures influence on epigeic beetles. These parameters were: the species diversity, the abundance and the ammount of relict species. It was collected 3099 beetles and it was managed to identify 54 species at all. The interest groups of invertebrates were ground beetles/carabids (Carabidae) and rove beetles (Staphylinidae). The results differed for both groups. The rove beetles were generally more abundant, than ground beetles and most of them were found in crops in the year 2009. The lowest numbers were caught in crops 2011. There was a quite remarkable contrast between these two results. The species diversity of rove beetles was too lower, than the ground beetles? one. The results of biodiversity seemed to be strange so as the abundance was. The diversity was the highest in the crops 2009 and the slowest in the crops 2011. Nearly the same diversity was found in biobelts, which are really different type of habitat. The carabids? abundance was not so oscillating like by the rove beetles. They were the most abundant in biobelts and the less in permanent belts. The abundance in crops in both years was nearly the same. The species diversity was highest in permanent belts and the lowest in crops in the year of 2009. The results about antropic influence on epigeic beetles assemblages, based on ecological characteristics of beetles, were eventually raised. It was established, that all the populations are strongly affected by human. The results say, that habitats like biobelt and permanent belt seem to have a positive impact on epigeic beetles assemblages, namely on relict or rare beetles survival. The results have very disparate and sometimes contradictory nature, thus cannot be sumarized.
