Effect of management and soil conditions on the frequency of field vole (Microtus arvalis) and common mole (Tapla europaea) in grassland
 ŠPILAUER, Tomáš
This thesis examines the influence of grassland management and soil conditions on the occurrence of field voles (Microtus arvalis) and common moles (Talpa europaea) in grasslands. Literature review covers soil conditions, meadow management practices, and descriptions of the two species. The practical research involved ob-serving and counting molehills and field vole burrows on defined plots. All new molehills and burrows on the pasture and meadow were recorded. The study was conducted on two plots in two periods: Plot 1 (May 2023 - March 2024) and Plot 2 (February 1 - March 22, 2024). Differences in management methods and soil conditions affected the occurrence of the animals. Burrows were more prevalent in meadows, while molehills were more common in pastures. Waterlogged meadows had no burrows. Molehill occurrence was influenced by vegetation cover and soil disturbance. Most molehills and burrows were observed between November 2023 and the end of March 2024.

The thesis focuses on the possible causes of this damage. Furthermore, the thesis mentions rodent species and their distribution according to food consumption, followed by a description of economic and sanitary damage. The thesis also mentions preventive measures against rodents, monitoring, methods of damage control and their economic impact. The thesis concludes by mentioning possible gaps in knowledge of the impact of annual crops on damage levels and potential alternative options for rodent damage control.

Is the abundance of the field vole on immission clearings in the Ore Mts. influenced by climatic conditions?
 HRINDOVÁ, Veronika
The aim of the study was to find out the character of abundance fluctuations in a field vole population on immission clearings in the Krušné (Ore) Mountains during a 25 year series of trapping. Another aim was to find out the influence of climaticconditions on these cycles, concretely the influence of local climatic condition and the influence of North-Atlantic oscillation
