DOIAbstract
The species number of rat, fruit bat, and insectivorous bat was signifi-cantly correlated with island size when five major islands of Irian, Borneo, Su-matra, Sulawesi and Java were included in the analysis, and the z area values were 0.22; 0.19 and, 0.26, respectively. When these islands were excluded, the correlation between species richness and island size was significant in fruit bats and insectivorous bats (R2=0.31, P<0.01) but not in rats. Z value declined to 0.07 in rats, 0.14 in fruit bats and 0.19 in insectivorous bats. Zoogeographic bounda-ries are shown. Wallace’s Line seems to be a zoogeographic boundary for all of three mammal groups; Bali and Lombok Islands belong to the cluster of Lesser Sunda in rats but not to the cluster...
