From December, 1972, to November, 1973, wood mice, <I>Apodemus argenteus</I>, were captured monthly by snap traps in the mountain zone (1000m above sea level) on Tobira Pass in Honshu. The total number of captured wood mice was 108. The hearts were removed and carefully separated to right ventricular wall and left ventricular wall (including interventricular septum) . Then they were dried and weighed. Measurements were analyzed in relation to seasonal temperature changes in the habitat. Seasonal changes in ventricular weights were observed in wood mice with significantly heavier total ventricular weights, left ventricular weights and right ventricular weights occurring during late autumn and winter than in summer. These changes are considered to be one aspect of metabolic acclimation to seasonal temperature changes, especially to decreasing temperature in late autumn and winter.
