Diversity hotspots in manor gardens
PANGRÁC, Čeněk
This thesis study differences between insect diversity of manor gardens and economic forest, as well as the importance of manor gardens within the local biodiversity of insects. Data were collected at six localities (Vlašim, Konopiště, Vrchotovy Janovice, Hluboká nad Vltavou, Český Krumlov and Třeboň). Carabids were collected in spring, summer and autumn terms during 2019. The specimens were collected via pitfall traps. There was inspected no statistically significantdifference in the diversity valuesbetweengardensand forests. The individual data showed a close relation between insect and plant diversity, as well as indicative species for garden and forest areas. The importance of manor gardens was identified primarily in a landscape which is intensively used for agriculture or with a lower proportion of natural habitats.

Druhové spektrum střevlíkovitých (Carabidae) v porostech polních plodin
Hurajová, Erika
In the stands of winter oilseed rape, winter wheat and corn on parcels in Miroslav I investigated species representation of ground beetles (Carabidae). I carried out using collections of ground traps at ten-day intervals. To each crop I ranked 5 ground traps. I founded ground traps 18. 5. 2016 and kept to the land to harvest crops (oilseed rape 3. 7. 2016, wheat 27. 7. 2016 and corn 15. 10. 2016. I caught a total of 371 individuals from the ground beetles of 29 species. I caught in the oilseed rape 72 individuals from 13 species, in wheat 128 individuals from 16 species, in corn 171 individuals from 18 species. I classiffied species in to bioindicatory groups: 44,83 % E, 51,72 % A, 3,44 % R. I used ecology characteristics: presence, absence, dominance, Simpsons index, constance, species diverzity, equitability and faunistic similarity.

Porovnání fauny slíďákovitých pavouků pastvin skotu a ovcí v okolí Nasavrk
Blažek, Jiří
The main target of my diploma thesis was the comparison of wolfspider fauna on cattle and sheep grazing pastures. For this reason I laid pitfall traps at these pastures during three months of 2017. I collected pitffall traps every month. Totally I got 90 samples. 3418 spiders were caught in total, from this 1164 individuals belonged to wolfspiders. I determinated all adults wolfspiders and sorted them into 6 species. Ammount of spiders and wolspiders of course varied during the time of study. The most abundant month was May (2532 spiders, 876 of wolfspiders), the number of caught spiders was decreasing rapidly in following months. The most numerous wolfspider spieces was Pardosa palustris (77 % of all wolfspiders). No red list or rare species of wolfspider was caught. Results of study prove that abundance or species diversity of wolfspiders isn´t influenced by species of grazing animal. But intensity of grazing has influence on species diversity and abundance of wolfspiders and spiders generally. Both indicators are decreasing with increas of grazing intensity.

Activity of Invertebrates in Winter and the Verification of the Selected Invertebrates Capturing Methods During the Winter Season
Babůrek, Jan ; Říhová, Dagmar (advisor) ; Hanel, Lubomír (referee)
This diploma thesis is focused on invertebrates' survival and activity during winter; and on methods of their capture. The first part of the theoretical section describes principles of cold hardiness, strategies of winter survival and activity in snow environment. Furthermore, different methods of invertebrates capturing are presented. The practical part of the thesis is focused on the verification of selected invertebrates capturing methods during winter. The results summarize the differences in the diversity and quantity of animals caught; and provide an overview and characteristics of selected captured taxa. Suggestions for a snow fauna excursion and a practical exercise focused on capturing invertebrates during winter are proposed based on the results of the study. KEYWORDS cold hardiness, winter survival, winter activity, snow fauna, invertebrate animals, catching methods, pitfall traps

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.

Využití ramopových pastí (ramp traps) pro průzkum biodiverzity - review
Skopalová, Barbora
The aim of this thessis is to review the method of collecting invertebrates using ramp traps with a focus on epigeon, ie invertebrates living and moving onthe earth's surface. Compare the advantages and disadvantages of this method with ground traps and suggest why using those traps or not. Both methods have their advantages and disadvantages, but the benefits greatly outweigh the ramp traps. In the case of ramp traps the material is always clean and free of impurities fallen plant material. It is hinted significantly less vertebrates and more needed invertebrates (ground beetles, spiders). They are difficult to prepare, but the actual use in the field is easier. They do not require distortion field diging as the method of ground traps. Based on the findings can be clearly recommended transition from ground traps to the ramp trap.

Nosatcovití lesních ekosystémů Beskyd
Hrabovský, Karel
Author: Karel Hrabovský Title: Weevils forest ecosystems of the Beskydy The aim of this thesis was to determine the significance of the family Curculionidae as a bioindicator and evaluate the possibility of its use in the classification system of forest typology. in the years 2007-2010 in the area of Moravskoslezské-Beskydy (massif of Smrk, Kněhyně and the valley of the Čeladenky creek in Podolánky) the fauna of the family Curculionidae in 38 stands of Norway spruce (Picea abies (L.) Karst.) and beech (Fagus sylvatica L .) was observed using pitfall traps. A correlation between the occurence of certain species of the family Curculionidae and the altitudinal vegetation zones (LVS) and edaphic category (EK). The sets of forest types (SLT) seem to be units too specific, we did not yet succed to prove a correlation with the family Curculionidae in these.

Drobní obratlovci v lesních ekosystémech Krušných hor a Děčínské vrchoviny
Těšík, Jindřich
The research was focused on the evaluation of trapping of common shrew, a small shrew, bank vole yellow--necked mouse, rat shrub, wetland voles with analysis of population and seasonal dynamics. Structures of capture common shrew, small shrew and bank vole were described more detailed. Animals were compared on base of nature conditions of localities. Conducted trapping of small terrestrial mammals took place in eastern part of Krusnohori (2003--2004) and Decin Highlands (1987--2013). 1831 small terrestrial mammals of 9 species (insectivores 4, rodents 5) were caught in the eastern part of Krusnohori and 2924 individuals belong to 11 species (6 insectivores, rodents 5) were caught in the Decin Highlands.
