Резюме: Target species for this study are 11 wild mammal species and feral dogs. The analytical methods for camera trap data include: occupancy modelling, activity pattern and overlap analysis, time-spacing analysis. The analytical methods for telemetry data include: activity pattern analysis, movement and speed analysis. Based on these results, the following conclusions can be drawn: - The interspecies relationships have the strongest impact: for the roe deer – its competition with red deer; for the red fox – its competition with Martes spp. and the predator-prey relations with murids; - The presence of the roe deer can be considered as a satellite for the red deer. - The wild boar has a strong negative impact on the presence and occupancy of the red deer and roe deer. However, the presence of red deer impacts positively the occupancy of the wild boar. - The brown bear and wild boar are present in the same habitats, but their activity patterns are different. - Martes spp. present as generalist. Neither of the studied spatial parameters influences significantly their occupancy. - The occupancy of the red fox depends on: the presence of murids as its food base; the presence of the competitors Martes spp.; the presence of predators; - The presence of Martes spp. has a negative effect on the red squirrel; - The mechanism of avoidance of the murids towards the red fox is temporal avoidance.
