In the work entitled "Ecology and Ethology of the Roe deer (Capreolus capreolus) in the selected areas of the Dunaj Hunting Ground" we are presenting roe deer in Slovakia. Based on literature and knowledge, we have characterized deer in the area of the Danube Meadows in the areas of Dunaj Hunting Ground. First, we give a detailed description of deer, as an external characteristic, which includes body size, body weight, body structure, skeletons, rats and traces, skin and hair. Then, the inner system of roe deer is described, including the respiratory system, the circulatory system, the sensory organs, the digestive system, and the sexual and urinary system. Deer teeth are also described as teeth develop and in which month of life. Developments, deadlines, and when new ones grow up are described in antlers. The social life was characterized by the behavior of individuals, the territory in which they live, the creation of churches and the mating season. Also, the most well-known diseases of deer, infectious, parasitic, etc. have been described.The next part of the bachelor thesis was characterized by the territory of the Dunaj Hunting Ground. General information about hydrological conditions, climatic conditions, boundaries was described. We have also reported negative animal-threatening factors. The results represent the evaluation of the captured individual's trophies, as well as proposals for the hunting plan, NKS and JKS for the selected period 2013-2017 and proposals for measures to improve management.Objectives:1.Characteristics of roe deer and characteristics of the monitored area2.Evaluation of the individual's trophy, as well as proposals for the hunting plan, NKS and JKS for the selected 2013-2017 period and proposals for measures to improve management
