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.

Biodiversity of staphylinid beetles (Coleoptera, Staphylinidae) in the Bohemian Forest - recent state, endangered species and their biotopes
Boháč, Jaroslav ; Matějíček, J.
More than 300 species of staphylinid beetles were found on 68 lokalities in the Bohemian Forest. 75 (23%) species of the all fauna belong to the Red list of the CR (5 critically endangered species, 27 endangered species and 43 vulnerable species). The most important biotopes for staphylinids in the Bohemian Forest are: petasites fringes of montane brooks, reedes and tall-sedge beds, foret springs, fens and transitional, mires, raised bogs, screes subalpine tall-forb vegetation, meadows and pastures, forest fringe vegetation, montane grey alder galleries, ravine dry pine, beech and spruce forests.
