. The Canadian field-naturalist. 1987 Klenner: Seasonal Movements and Home Range of the Black Bear 563. 5 km r:::i::i:l Forest Eastern Boundary DMPF I I Agricultural Land and Woodlots Figure 2. Home ranges of representative subadult (SAF) and adult (AF) female Black Bears in western Manitoba during 1980. The areas indicated represent 95 percent utilization ellipses. ranges were more stable and showed less change than subadult males from spring to fall (t = , df = 7, p = ) as well as between the summer and fall range (t = , df= 12, p = ). Home range overlap between male bears being monitored was extensive, ranging from 30 to 100 percent of the home range area. Since additional unmarked subadult and adult males were known to make at least periodic use of the main study area, overall home range overlap between males was probably higher than I documented. Home range overlap between males and females was also extensive. The home range of male M795 overlapped all females being monitored in the study area (compare Figures 2 and 3, noting differences in scale). Even male M793, whose restricted movements in 1980 resulted in a smaller than average home range, overlapped six adult and subadult females. Of the 12 adult and subadult females monitored in 1980, there were 22 combinations which showed greater than ten percent overlap of their MCP home range (Table 3). Regression analysis indicated a strong relationship between the proportion of the home range and the proportion of locations in the zone of overlap (r = , p= ). Annually, overlap between subadult-subadult (n = 8,1c = ), adult-adult (n = 8, x= ) and subadult-adult females (n - 28, x= ) did not differ significantly. All groups showed a significant decrease in overlap during fall when movements were restricted to localized areas. Extensive home range overlap by three adult females in one area was also recorded (Figure 4). It is important to note that these are conservative estima
