Summary Local distributions of two species of Apodemus, A. argenteus and A. speciosus , were studied by the correct estimation of peak density of mice and the detailed description of the habitat. Multiple regression analysis is applied to these distributional data setting with four variables as altitude, forest type, relative cover of shrub layer and age of forest. The local densities of both species and the percentage abundance of A. argenteus can be completely predicted by use of the regression coefficients. The density of A. speciosus correlates with the altitude of habitats, and that of A. argenteus does with the age of forest. The mean relative cover of shrub layer influences the dominancy of A. argenteus when both species occur sympatrically.
