The rate of development and body size of carrion beetles (Coleoptera: Silphidae).
Štrait, František ; Jakubec, Pavel (advisor) ; Qubaiová, Jarin (referee)
The goal of this review is to introduce the Silphidae family to the reader and summarize the ecological and geographical aspects of this family, their morphological features, and their dietary requirements.
Additionally, I analyze the evolution of insects when exposed to abiotic factors and their adaptation to them. I also described the issue of forensic entomology depending on the evolution of insects, the complete developmental stages of insects including the time of feeding, and the competitive fight for carrion.
I also described the application of insects in forensic entomology and the identification of insect larvae.

Chorošovité houby jako centra druhové diverzity hmyzu
Schreiber, Michal
The goal of the thesis is to find out as many as possible information from the available literature about fungivorous insect (primarily Coleoptera) associated to Polyporaceae. The literature review summarizes chiefly information about regions, in which this issue was studied, also the main methodologies of study of entomofaunas on Polyporaceae were described, which were used by many authors in different areas and also the problem of fragmentation of forests is outlined. In the conclusion of thesis the shortages of previous researches were defined. In the appendix the list of species was made, including families, which were found out from available literature and host fungi species on which every species was described.

Active management effect on floricolous insect diversity in oakwoods of Thayatal National Park.
PERLÍK, Michal
Two experimental clearings (isolated by dense forest from all sides and connected to medow from one side) and four control plots (medow, dense forest, sparse forest, forest edge ) were established on six localities in Thayatal National Park. Pan traps were used to collect floricolous insects. Diversity of floricolous beetles (coleoptera) have been assessed using multivariate analysis. Effect of active management for diversity conservation is discussed.

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.

Effect of grazing in submoutain regions on biodiversity of invertebrates - epigeic beetles.
RUTTA, Petr
Diplomová práce se zabývá biodiverzitou epigeických brouků na pastvinách nacházejících se v podhorských oblastech Šumavy. Srovnává jak se mění biodiverzita společenstev již zmíněných brouků v oblastech s různou intenzitou pastevního zatížení. Odchyt byl prováděn na dvou odchytových místech pomocí zemních pastí. V práci je zjištováno srovnání biodiverzity společenstev epigeických brouků v oblastech s různým zatížení pastvou, porovnání s dosavadními výsledky, antropogenní ovlivnění stanovišť a ordinace druhů na pozemku.
