The impact of ungulates on epigeic assemblages of centipedes (Chilopoda) in the Křivoklátsko Protected Landscape Area - preliminary results
Aurová, Klára
The Křivoklátsko Protected Landscape Area and Biosphere Reserve (Czech Republic) represents a unique region covered in a high portion by forest ecosystems. Densities of ungulates in the forests are unusually high. Their impact on ecosystem is important, especially due to the removal and consumption of herbage, trampling of soil and vegetation, and the return of excreta. The aim of field study was to elucidate the impact of ungulates on soil invertebrates represented by centipedes. In this paper the first data about possible impact of ungulates on epigeic assemblage of centipedes are presented. In total, 9 centipede species were recorded. The species .i.Lithobius mutabilis./i. was dominant during the whole observation in all monitored plots. At the beginning of the experiment in 1994, this centipede outweighed other species with 91 %. After 12 years in 2006 the amount of other species arose almost up to 1/4 outside and more than 1/3 inside the fenced plots.

Free living ungulates and field crops
Kamler, Jiří ; Dvořák, J. ; Heroldová, Marta ; Homolka, Miloslav
We evaluated the importance of field crops for the ungulate game species. The large herbivores exploit the field crops at the different intensity according to crop species, season, feeding strategy, human disturbance in the forest etc. The field crops are generally not too important as a food resource for wild ungulate species and in the environment with sufficiency of herb and shrub layer in the forest environment they prefer native diet components.

The natural seasonal changes in the food choice and digestive tract of wild ruminants
Kamler, Jiří ; Homolka, Miloslav
Herbivore populations all over Europe have been strongly influenced by human activities. A combination of harvest, changes in forest structure, supplementary feeding, predator extirpation and others factors have led in most cases to increases of their populations and a severe impact on the composition and structure of the forest vegetation. The food choice of free living ungulate species is strongly influenced by season and animal species and changes in diet composition and quality cause the changes in the digestive tract. Effective management of ungulate populations and forest ecosystems should be based not only on detailed information about the impact of deer browsing and the number of deer to harvest but also on the density of deer species, the food supply, the structure of diets consumed by individual species, attraction and quality of the individual components of food supply the total quality of food taken and seasonal changes in digestive tract.

Foraging strategy of ungulates on Pavlovske vrchy hills
Heroldová, Marta
Study on foraging strategy of three ungulate species (Capreolus capreolus, Capra aegagrus, Ovis musimon) elucidates the problem of mutual coexistence and competition. High impact on unique flora of Palava Hills leaded to decision to lower the number of ungulates and eliminate Capra aegagrus from this locality.
