Abstract

The roosting ecology of Murina ussuriensis were examined using dead-leaf Mallotus japonicus traps and radio transmitters in warm-temperate forests in the Kyushu district, Japan. Recapture rate at natal sites after the first year averaged 13% for yearling males, and 16% for yearling females. Adults roosted individually in the active season, expect for females during the breeding season from June to August. Adult males roosted in the lower and middle layers of forests from May to October, and frequently switched their day-roosts. Adult females formed maternity colonies in the middle layer of the forest, and frequently changed their maternity roosts. After nursing, adult females roosted individually in the lower layers. In the adult stage, 44% and 42% of recaptured male and female bats, respectively, remained at the capture location. In the case of movement, the average shifting distances were 116 m in males, and 209 m in females. Some of the young bats weaned in summer reached sexual maturity in autumn of the same year. The oldest age determined for M. ussuriensis was four years in males and 4.5 years in females.
