Abstrakt: The article discusses a research which tested niche segregation in the habitat between abundant carnivores using presence-only data. Results show that the presence of genets and stone martens were both detectable by tracks and signs but genets were more detectable by live trapping. It was observed that genets had broader niche and used more habitat variables than stone martens. A large overlap between the two species was also observed. Logistic regression analyses revealed that meadows, altitude and structure 3 at the home range scale were the important variables differentiating the niches of the two species. The presence areas of genet and stone marten at the local landscape scale was differentiated mainly by the proportion of structure 3, rocky outcrops and relief.
