The effect of management on biodiversity of forest ecosystems - epigeic beetles on selected habitats of Písecko
STLUKA, Petr
Communities of epigeic beetles were studied on three forest habitats with the different forms of management in South Bohemia area, Písek district, close from Zátaví village. Selected areas were located in territory of Zátavský forest. There were these habitats: clearing, young spruce forest stands (age 6 years) and spruce forest (age 50-70 years). The method of pitfall trapping was used for biological material capture. There were 1813 specimens and 63 species of epigeic beetles trapped and determined. The highest number of species and individuals was found in spruce young forest habitat (43 species, 786 specimens), than followed spruce mature forest habitat (26 species, 550 specimens) and glade habitat (35 species, 477 specimens). Most species of epigeic beetles from 63 aggregate number of species was classed like eurytops. There were also 15 adaptable species determinated and it was found 1 genus of relict from I. degree too. It was found that spruce forest, which seems like more mature in terms of succession than young forest or glade, had no highest number of species and individuals. Conversely the largest number of species and individuals was found in spruce young forest. Index of antropogenic influence proved relatively strong antropogenic effect all studied habitats in terms of epigeic beetles. Communities of beetles were least affected in spruce forest, than followed young spruce forest and glade. From this point of view, intensity of management had the most effect on glade´s communities of beetles. Mature spruce forest had the least antropogenic influence on communities of beetles.

Ecological consequences of habitat loss in landscape matrix and the effect on populations and communities of model species
HELLEBRANTOVÁ, Adéla
The effect of fragmentation on populations was studied using epigeic beetle collected by pitfall traps with ethylenglykol. Pitfall traps were placed at three sites and namely in: artifical spruce forest, bio-corridor and meadow in the vicinity of České Budějovice on agricultural landscape. The material was collected from May to September. Beetles were determined and classified into goups according to the level of tolerance to anthropogenic influence. The communities (species richness and its activity) were compared in cited biotopes (fragments) in the agricutlural landscape. The highest number of species and its activity was detected in the bio-corridor. The lowest number of species and its activity was found in the spruce forrest. Thel effect of size of biotope was not found. At a meadow and biocorridor previled beetle species named as eurytopic which are characteristic for deforested habitats strongly influenced by human activities. In the forest, the other half consisted of RII. Group, which are adaptable inhabiting habitat moderately affected by human activity.

Military areas as biocentres
DEDEK, Jaromír
Communities of epigeic beetles were studied in the army training areas Dobrá Voda and Boletice. Three biotopes (spruce forest, meadow, wetland) were monitored using pitfall traps with ethylenglykol from May to September 2012. Altogether 50 species were found in Boletice and 32 species in Dobrá voda. Species richness and abundance were higher in Boletice. The protected species Carabus scheidleri was indicated in Boletice. In the Dobrá Voda other great Carabus species were found (e.g. Carabus auronitens auronitens, Carabus granulatus granulatus, Carabus nemoralis nemoralis, Carabus sylvestris sylvestris, Carabus violaceus violaceus). The hiogh frequency (60 %) of eurytopic species was typical on both territories. It seems (after our results), that the initial successional stages support the higher biodiversity of epigeic beetles in both territories. It is the reason that we recommend the active management in non forested areas (cutting of ingrowing plants or the training activities of army in territory with army training, or pasturing, training of cars and motorcycles, etc. in abandoned training areas). The forested areas should be under natural succession.

Biodiversity of epigeic beetles on selected field crops - effects of management on the structure of communities
SVOBODA, Richard
Epigeických beetle communities were studied on four agroecosystems with different crops grown. All four agroecosystems were located in the vicinity of Czech Budejovice (South Bohemia). The first agroecosystem is conventionally grown corn. On the second one agroecosystem it was conventionally grown wheat. The third agroecosystem was barley and the fourth was permanent grassland. Individual agroekosystems differed not only in crops but also in agrotechnical operations during the capture. In all agroecosystems was for capture of the material used method of pitfall traps. Subsequently, those types have been studied. Then was studied degree of human impact on the biodiversity of species of different ecological groups found in these locations.Beetle activity was highest in the maize agroecosystem. There was found almost half of all captured individuals. In all agroecosystems was activity affected by management of agrotechnic operations and also by for that year specific weather. All sites were completely dominated by expansive species (E - types of deforested habitats strongly influenced by human activities)

Knowledge management in project management
Klempová, Hana ; Chocholatý, Drahomír (advisor) ; Řepa, Václav (referee)
The thesis is focused on knowledge management and discuss the possibilities of its usage in the area of project management. Knowledge management comes up with systematic work with knowledge. The aim of knowledge management is to create a company culture which motivates employees to share and apply their knowledge in an effective way. Knowledge is today a huge competitive advantage and it makes companies get interested in knowledge management ant its implementation. Communities and knowledge base are great tools of knowledge management and they both have a great potential of usage in different areas.

Influence different management on primary production and biodiversity epigeic and hemiedafic beetles in observed drainage area in Šumava.
KISSOVÁ, Lucie
Communities of epigeic beetles were studied on two water catchments with the different management in the submontaneous area of Bohemian Forest (South Bohemia, Czechia). The Mlýnský stream catchment was characteristic by high representation of unforested habitats (pastures and mowed meadows), Horský stream by higher proportion of forested habitats and non equal management (plots without management). The biomass characteristics (above ground and dry) were measured on studied plots. The method of pitfall trapping was used for beetle sampling. Beetle species were divided into two groups after its preferences to shaded: species occurring in unshaded habitats and species occurring in shaded habitats. The degree of human impact was studied by finding of frequency of species of different ecological groups. The above ground biomass was about 2 time higher in Mlýnský stream than in the Horský stream. The dry biomass was practically the same. 57 species was found in the Mlýnský stream and 33 in the Horský stream. The activity of beetles was about five times higher in Mlýnský stream than in the Horský stream. Ubiquitous species prevail in Mlýnský stream and adaptive species in the Horský stream. Stenotopic species were found in the Mlýnský stream only. These results indicate less human impact in Horský stream than in the Mlýnský stream. Beetles prefering unsheded habitats slightly prevail in Mlýnský stream in comparison with Horský stream. Beetle species characteristical for shaded habitats occur in Horský stream in comparison with Mlýnský stream. The geographical exposition affected the beetle structure mainly in the less forested plot of Mlýnský stream. The structure of communites situated to the south differs from communities situated to the north in Mlýnský stream. The effect of exposition is not documented in Horský stream with the greater proportion of forested size.

Different management effects of on microclimate and biodiversity of epigeic and hemiedafic beetles in a monitoring watersheds (area) in Šumava.
CHOCOVÁ, Hana
SUMMARY Communities of epigeic beetles were studied on two water catchments with the different management in the submontaneous area of Bohemian Forest (South Bohemia, Czechia). The Mlýnský stream catchment was characteristic by high representation of unforested habitats (pastures and mowed meadows), Horský stream by higher proportion of forested habitats and non equal management (plots without management, mowed meadows). The microclimatic characteristics (average temperature, average humidity, average wind speed, average radiation) were measured. The method of pitfall trapping was used for beetle sampling. Beetles species were divided into two groups after its preferences to humidity: hygrophilous species and mesophilous species. The degree of human impact was studied by finding of frequency of species of different ecological groups. 57 species was found in the Mlýnský stream and 33 in the Horský stream. The activity of beetles was about five times higher in Mlýnský stream (511 individuals captured) than in the Horský stream (114 indivuduals found). Ubiquitous species prevail in Mlýnský stream and adaptive species in the Horský stream. Stenotopic species were found in the Mlýnský stream only. These results indicate less human impact in Horský stream than in the Mlýnský stream. Frequency of beetle species with the different requirement on the humidity in communites on studied plots indicates the dominance of mesophilous species in Mlýnský stream in comparison with Horský stream. Frequency of hygrophilous species was about three times higher in Horský stream than in Mlýnský stream. The intensity of management affected the beetle structure mainly on the less forested plot of Mlýnský stream. The structure of communites on plots with more intensive management differs from communities on plots with low management. Hygrophilous species prevail on plots with low management of the Mlýnský stream. The effect of management intensity is not documented in Horský stream with the greater proportion of trees.

Společenstva žížal ve středoevropských bukových lesích
Pižl, Václav
The aim of the study was to summarize data about earthworms inhabiting beech forests in the Czech Republic and to compare faunas of different beech forest types. Forty-five beech forests located across the country were sampled for earthworms during 1994-2004. In total, 30 species and subspecies of earthworms were identified, among which .i.Dendrobaena octaedra, D. vejdovskyi, D. illyrica, Dendrodrillus rubidus, Lumbricus rubellus, Octolasion lacteum./i. were most frequently recorded. Moder soils of acidophilous forests contained only 3.2-48 animals per square meter out of 1-6 epigeic species, however, mull soils of neutrophilous herb-rich forests possessed rich earthworm communities (8-14 species, 65-211 ind.m.sup.-2./sup.) composed of the representatives of both epigeic, endogeic and anecic earthworms. Soil pH was suggested as the main factor determining the inter-site differences in earthworm density.
