Metoda stanovení struktur početních stavů populací spárkaté zvěře

The diploma thesis deals with the determination and expansion of numerical structures for Cloven-hoofed game ie. for roe deer (Capreolus capreolus), red deer (Cervus elaphus), fallow deer (Dama dama), sika deer (Cervus nippon), white-tailed deer (Odocoileus virginianus), mouflon (Ovis musimon), chamois (Rupicapra rupicapra) and wild boar (Sus scrofa). The social structures of female game numbers for different sex ratios have been developed and can be used in different types of breeding. Based on the model cases performed, it has been confirmed that, with a limited number of individuals in the population, the number of youngsters and the number of adults decreases in nature at the sex ratio in favor of females due to spontaneous game reduction. As a result, the average age of adults is reduced, and younger years are getting into reproduction. Another negative aspect of this unbalanced sex ratio is the increase in cloven-hoofed game and related damage and intraspecific stress. In addition, for some game reserves, if the sex ratio is increased for males, there are problems of a similar character, which are being overcome by greater losses in heat fights. This creates additional economic damage. Model cases have shown and confirmed that, with a limited number of game and around a balanced gender ratio of 1:1 to about 1.2:1 in favor for males and 1:1.2 in favor for females, there are no problems with population control because it is predictable. Once the gender ratio is wider, basic problems arise and that is poorly breeding. These wider gender ratios are on one side and the other unnatural in nature and therefore carry many problems.
