Movements and use of home range in the Iriomote cat (Prionailurus bengalensis iriomotensis)

摘要: Movement pattern of the Iriomote cat Prionailurus bengalensis iriomotensis was studied on Island, Japan by radio-tracking. The influence sex and reproductive status cats their daily movement distance (DMD), straight-line (SLD), range (DMR) other relative indices movements estimated. DMD longest in males (3.2 km) shortest females without kittens (1.9 km). Also, moved faster than either with or (0.34, 0.25 km/h, respectively). During mating season, DMRs were larger during rest year. SLD/DMD ratio similarly high both seasons (0.29 0.33), which indicates that routes expanded over large areas year-round, possibly to maintain a continuous control home range. In contrast, varied seasonally breeding females. It low (0.09) lactating period, when returned repeatedly den it became (0.32) out season. Breeding equally long DMDs seasons, whereas non-breeding ones shorter distances period. These differences may be related seasonal changes food abundance. Cats intensively, as indicated (812–1139 m) per km2 range, occasionally visited distant parts ranges short time (4–5 days). On hand, they showed relatively slow increase patrolled area, from 10% 36% ranges, first fifth day, respectively. no clear relation active defence ranges.
