Bark beetles in forest ecosystems with disparate disturbance regimes
 Zemanová, Jana ; Horák, Jakub (advisor) ; Jiří, Jiří (referee)
This thesis evaluated the influence of the forest environment with various rate of disturbance. Studied sites were left to spontaneous succession. The method of trunk window traps was used. These traps were divided into pairs at monitored sites. Each pair comprised active (with yellow label attached) and passive trap. The influence on the bark beetles was evaluated by statistical analysis. In total, 346 individuals were captured and 12 species of bark beetles were identified. The influences of the environment (circumference of tree trunk, canopy openness, dead wood, altitude and type of trap) were significant for the number of individuals, the total body length, the width of shield and the length of elytron. Wing length was only affected by circumference of tree trunk, canopy openness and dead wood. Number of species was only influenced by altitude.
