In the thesis, we calculated the value of relative natality of brown bear populations (Ursus arctos L.) in Europe. We studied the effect of geographical latitude and local densities on relative natality, and we were also interested in differences between natality in areas where artificial feeding is allowed and where it is not. The same goes for the effect of harvesting. Furthermore, we sought connections between natality and reproductive parameters. We gathered information by examining literature from experts. Where it was possible, we summarized the value, otherwise we calculated it using data from a survey we sent to brown bear experts (LCIE). In our research, we did not find any connections between relative natality and our research variables. However, we did document that estimated values of relative natality are most likely between 20 % and 25 %. A result that stands out comes from the Apennine area, where we found the lowest estimated value of natality, which could be due to small numbers of individuals in the brown bear population (the Alee effect). The results may vary because we used different methods to estimate relative natality and the data that we used was not always comparable between countries. Furthermore, some values of natality could be unreliable (underestimated).
