Results of research on crab-eating mongooses (Herpestes urva) in Taiwan, however, indicated that this species has a body size which lies between the social and solitary mongooses (adult weight ~ 2 kg). They live in forest, but are diurnal. They mainly feed on invertebrates, including crustacean and insects, but may occasionally feed on amphibian, reptile, and small mammals. Direct observation indicated that they are mostly solitary, but they may also form loose or temporal aggregation. Their social organization needs to be confirmed by further examination. Results of such studies are important not only for understanding the species itself, but also for examining the predictions made by Rood (1986) and Gorman (1979). The goals of this project is to spend three years to study the social organization of crab-eating mongooses at Fushan Experimental Forest by examining the spatial distribution and interaction of individuals and their relatedness, based on radio-tracking and genetic analysis. Results of this project will be compared with relevant studies on other mongooses and will be used to examine and revise the proposal made by Rood (1986) and Gorman (1979).獴科食蟹獴空間分布社會結構無線電追蹤HepestidaeHerpestes urvaspatial distributionsocial organizationradio-tracking福山試驗林食蟹蒙之社會結構
