Selected factors affecting species and genetic diversity of oribatid mites (Acari: Oribatida) in Central Europe
 GALICOVÁ, Petra
The first part of the thesis focused on the impact of natural disturbances and subsequent management practices (natural regeneration vs. clear cutting) on the oribatid mites in the montane Norway spruce forest in Šumava National Park (Czech Republic). Our results showed that changes caused by logging after a natural disturbance could be evident even more than 15 years later, at least in oribatid mite communities. The results of a phylogeographic study of two closely related species are presented in the second part. Except for revealing distinct phylogeographic patterns in the populations of these species across Europe, one new species was discovered, and its morphological and genetic description is provided.

Communities of oribatid mites (Acari: Oribatida) of naturally regenerating and salvage logged mountain spruce forests of Šumava Mts
 GALICOVÁ, Petra
The main aim of this study was to describe and compare communities of oribatid mites of selected areas in mountain spruce forests near Březník in the Šumava National Park, where different types of management were used after the spruce dieback caused by bark beetle gradation more than 15 years ago. Naturally regenerating and salvage logged areas were compared. Significant differences were found in the oribatid mite community composition between the areas with different types of used management. The oribatid mite community in naturally regenerating areas was in better shape and its abundance and species composition was similar to the community of a control area in a fully grown healthy spruce forest.

Effects of management and natural disturbance on oribatid mites in montane forest
 FARSKÁ, Jitka
The thesis studied effects of forest management and natural disturbance on oribatid mites in montane forests in South Bohemia (Czech Republic). We focused on the influence of (1) spruce monoculture establishment on the former beech forest, (2) management intensification in spruce forest and (3) forest dieback after bark-beetle outbreak. The impacts were pronounced especially like changes in species composition and distribution of functional traits.
