Rood (1986) and Gorman (1979) suggested that social systems of different mongoose species are related to the body sizes, habitats, activity patterns and food habits of these species. Social mongooses were smaller (adult weight of < 2 kg), living in open areas, diurnal, and primarily insectivorous; whereas solitary species were larger, living in forest, nocturnal, and mainly feed on small vertebrates. 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 system 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 system of crab-eating mongooses at Fushan Experimental Forest, including their social organization, social structure, mating system, based on mark-recapture, radio-tracking, behavioral observation, and genetic analysis. Results of this project will provide information on social system of an Asian mongoose species, which is important for comparison with relevant studies on other mongooses.&#29556科食蟹&#29556空間分布社會結構無線電追蹤Herpestes urvasocial organizationsocial structuremating systemradio-tracking
