Investigating associations of saproxylic beetles with forest structure through the analysis of species composition and feeding guilds
 KOZEL, Petr
The thesis contains studies focusing on various forest biotopes of Central Europe and saproxylic beetles as a model group for forest ecology research. In the review, current knowledge about the threats for forest biota, mainly saproxylic beetles are discussed in the context of species composition and trait-based approach. Various stages of succession in the patches of disturbed forests, their connectivity, the introduction non-native tree species, and the assessment of feeding guilds using stable isotopes are studied in the relation to saproxylic beetles in separate chapters.

Habitatové preference, stanovištní dynamika a management hmyzu vázaného na staré stromy
 PLÁTEK, Michal
The thesis presents studies on habitat preferences of beetles associated with senescent, open-grown trees and on dynamics and management of saproxylic habitats. It presents a brief insight into the current issues in the conservation of insects dependent on old trees. It presents the patterns of exploitation by a veteran tree specialist within old open-grown trees and the local patterns of tree exploitation by the same species at sites with different characteristics. Further, it presents a study of the effect of a prunning technique on formation of deadwood microhabitats, and also the importance of active interventions in closed-canopy forests for the communities in temperate lowland woodlands.
