Popis: Aspects influencing the distribution patterns of mammals are particularly important for species living in human altered landscapes. The current study investigated the relationship between occurrence patterns of large spotted genets (Genetta tigrina) with various environmental variables believed to influence their detection and site occupancy in an urban environment. Presence/absence data was collected from 28 camera trap stations between June 2012 and October 2013 in Kloof/Hillcrest suburbs, Durban, South Africa. Average estimated occupancy of G. tigrina was 0.62 ± 0.14 with a detection probability 0.19 ± 0.03. The naive occupancy was 0.607. Model selection indicated that bush cover and placement of camera traps on wide paths negatively influenced G. tigrina occupancy. Both winter and fringe habitats influenced the site occupancy of G. tigrina positively. Furthermore, bush cover was negatively associated with detection probability of G. tigrina. The current camera surveys provided baseline data for long-term species observations within suburban Kloof/Hillcrest. The present study indicated the importance of a variety of factors on the distribution of G. tigrina, particularly in landscapes where natural habitats are threatened with changing land use and increasing human populations.
