抄録

To elucidate arboreal habitat use by Apodemus argenteus and A. speciosus, the foot print recording method was applied in the field. The footprints of Apodemus argenteus and A. speciosus obtained previously in the laboratory were clearly distinguishable by linear discriminant analysis. The footprint recording method showed that arboreal habitat use by A. argenteus became active from early summer to autumn, while that by A. speciosus was low throughout the year. By comparing the footprint recording with the live-trapping method, it was suggested that the frequency of arboreal activity of A. argenteus measured by footprint recording reflected the number of individuals captured in an arboreal habitat as well as the arboreal activity per individual.
