| Spacing Pattern and its Dynamics of the Iriomote Cat | |
| 2007 Conference Proceeding | |
The Iriomote cat, _Prionailurus bengalensis iriomotensis_, is a small felid endemic to Iriomote-jima Island (284 km2) in the Ryukyu Archipelago, Japan. The home range and spacing pattern of the population in this cat have been investigated by radio-tracking and photo-trap since 1983. We summarized all data on home ranges obtained from 1983 to 2006 and estimated the spacing pattern and its dynamics. Iriomote cats were basically intrasexually territorial. Home range size varied among areas and among seasons, being affected by habitat conditions and reproductive behaviour. Females had small fixed home ranges and normally stayed in the same area for several years. Although home ranges of males were usually larger than those of females and sometimes they expanded during mating season, they were affected by the distribution of females. Furthermore, two types of males were observed: residents and transients. Transient males moved long distances and some of them were able to establish home ranges in vacant areas. Despite of home range shifts between individuals, the spacing pattern in the Iriomote cat was generally stable little even when the individual cats alternated as long as the habitat conditions remained unchanged. |
