小島に生息するノネコのグルーピングパターン GROUPING PATTERNS OF FERAL CATS (FELIS CATUS) LIVING ON A SMALL ISLAND IN JAPAN
IZAWA, Masako, DOI, Teruo & ONO, Yuiti (Dep. Biol., Fac. Sci., Kyushu Univ.). 1982. Grouping patterns of feral cats (Felis catus) living on a small island in Japan. Jap. J. Ecol., 32 : 373-382. Range utilization and social relationship of feral cats (Felis catus) were investigated by direct observation and radio-tracking. The range structure of the feral cat in this study also resembled the pathnetwork systems described by HEDIGER. The range of cat was composed of three characteristic components such as a feeding site, resting sites and paths. Each cat used only one feeding site and did not switch it seasonally. The cats utilizing the same feeding site organized "feeding group". Synchronization of feeding activity and overlapping ranges of the members of the same feeding group were observed. These features of feeding group show the amicable relationship among the members. It was considered to result in the adaptation to clumped distribution of abundant food resource.
