Home range area and habitat use of the wild Japanese macaque (Macaca fuscata) were investigated between elevations of 600 m and 3000 m in the Northern Japan Alps, in areas where there is great variation in vegetation type. A total of 22 troops were located either visually or by radiotracking from December 1996 to February 2000. The average troop size was 48.4 individuals, the average ranging area (65% probability distribution calculated using the adaptive kernel method) was 3.7 km2 and the average elevation of each troop varied from 740 m to 1458 m. Two troop types were distinguished according to their habitat use: (i) ‘rural’ type groups frequently utilized cultivated land (n = 12); and (ii) ‘natural’ type groups never utilized cultivated land (n = 10). Natural groups inhabited higher elevation areas and showed a greater dependency on deciduous broad‐leaved forests during all seasons. In contrast, rural groups utilized the larch plantation more in spring, and the red pine forest in summer. Rural groups were observed on cultivated lands more often from summer to winter than in spring. The size of the rural groups was twice as large as that of the natural groups. Troop size and home range area showed significant correlation within each group type. The per capita home range area of rural groups was smaller than that of natural groups. These results suggest that per capita home range area is negatively correlated with habitat quality.

Abstract. Movements and seasonal home ranges of 6 GPS collared sika deer were investigated at the Oku-Chichibu Mountains, central Honshu, from April 2009 to March 2010. All deer migrated between discrete summer and winter home ranges. The linear migration distance ranged from 2.5 to 31.9 km. Mean elevation during the summer and the winter ranged from 980 to 1,782 m, and from 1,204 to 1,723 m, respectively. Two deer were upward migrants and 4 deer were downward migrants. Taking into consideration of the relatively small snow accumulation in the summer home range, the possibility of autumn migration to avoid deep snow is low. The percentage of steep slope in the winter home range was higher than that in the summer. Bamboo grass was not found in the summer home range, but was predominant in the winter home range. Road density decreased in the winter home range compared to the summer. Only 2 out of 6 deer stayed mainly in the wildlife protection area during the winter. Our results indicate that the autumn migration was affected by winter forage and human disturbance, thereby assured the survival of the deer during winter.

Three features of early life course of Americans and Europeans during the twen tieth century are of note: (1) the increased age-grading of transitions; (2) the closer spacing of different transitions, and (3) the more extensive overlap between economic and family transitions. Historical changes in the structure of individual life histories have been interpreted alternatively, as a consequence of industrialization and urbanization, or as the result of rising levels of the family and personal incomes available for consumption and investment in human capital skills. In this article we bring additional evidence to bear on this debate by comparing historical changes in the early life transitions of men and women in Japan and the United States. Trends in the transition to adulthood systematically relate to the structure of schools and labor markets in the two nations, drawing attention to the various life course implications of the institutional forms under which industrial societies may organize.

We conducted a global positioning system (GPS) tracking of a male sika deer (Cervus nippon) and his mother in the eastern foothills of the northern Japanese Alps, central Japan. Sika deer exhibited similar seasonal movement patterns; however, the male deer left his natal group at 11 months of age. At 15 months of age, the male deer settled in the neighboring mountain, which was 74 km away from his natal range. This is the first record of long-distance (>50 km) natal dispersal of the sika deer. Our findings might help to explain the expanding distribution of the sika deer.
