Radio-telemetry was used to investigate the home range, movements and activity patterns of Africa... more Radio-telemetry was used to investigate the home range, movements and activity patterns of African Civet Civettictis civetta in Wondo Genet, Ethiopia, during November 2006–June 2007. Home-range size was calculated using the minimum convex polygon method (MCP). The home range of a sub-adult female was 0.82 km2 (100% MCP) and 0.8 km2 (95% MCP). The home range of an adult male was 0.74 km2 (100% MCP) and 0.71 km2 (95% MCP). For the two animals, average values of 2.8 km/day, 0.24 km2, 30%, 3,590 m of travel route/km2 and 326 m/h were recorded for daily movement distance, daily movement range, percentage of daily movement range in relation to total home range, intensity of movement and speed of Civets, respectively.

Civetry distribution and density, population density, diet analysis, seed dispersal and scent marking of civets were investigated. Civetries were distributed along pathways at various locations like forest, plantation, bushy area, grassland, farmland, open area, bare land, lake shore and home garden. Higher density of civetries were recorded in the farmland than in other areas (t = 5.6, df = 3, p < 0.05). A population density of 2.3−12.8 civets/km 2 was estimated. Civets feed fruits (36.9%), leaves and shoots (18.3%), roots and tubers (3.4%), invertebrates (19.1%), mammals (13.3%), birds (6.6%) and fish (2.8%) in the present study area. Fruits were the most preferred food item in all habitats. African civet is an effective seed dispersal agent. Over 70% of scent marked signposts were distributed around civetries in the farmland and natural forest areas, while about 35% of the scent marked sign-pots were distributed around civetries in the urban area. Most of the scent marked signposts were located at or close distance (< 2 m) to wildlife tracks. The amount of scent marks on signposts ranged between 0.0001−1.5110 g. The effect of season and habitat on population density and diet composition was insignificant in the present study area due to the habitat variability and modification. Fruit eating behavior of civets and widespread civetries distribution along various habitats have an important role in seed dispersal and implication for conservation of civets.
