We collected 170 focal observations from 54 groups in all regions of Adak Island (Table 1). The mean length of time of focal observations was 8.11 minutes (s = 2.17). One or more aggressions were detected in 59 focal observations, and we observed a total of 84 aggressions.   

Our measure of close proximity, proportion of time a focal animal was within one body length of other caribou, was unaffected by any predictor we considered because confidence intervals included zero (Table 2). In contrast, probability of aggression was least for females in female groups, intermediate for males in male-only groups, and highest for males and females in mixed-sex groups (Table 3, Fig. 2). We did not detect an influence from group size on probability of aggression across the range of observed group sizes in our data. Probability of aggression was also highest during the early summer and increased as animals spent more time in close proximity to each other, but was not influenced by the length of the focal observation.

Intense aggression was greater for males than females. The frequency of intense aggression (i.e., involved physical contact) was 0.16 (95 percent CI: 0.078 – 0.25) for males and 0.04 (0.009 – 0.075) for females. Intense aggression was 4.0 times more likely for males than for females (95% CI:1.42 – 21.57).

To quantify gregariousness, group sizes were recorded for 19 male-only, 27 female, and 23 mixed-sex group types. Minimum, quartiles, and maximum group sizes, respectively, were: 1, 2, 6, 9, and 20 for male-only; 2, 6, 11, 16, and 57 for female; 3, 10, 17, 32, and 161 for mixed-sex group types. Group sizes were smallest for male-only, intermediate for female, and largest for mixed-sex groups (Table 4, Fig. 3). Also, group sizes were larger during early summer than in late summer for all group types.

솔직히 저는 잘 이해가 안갑니다만, 당사자인 아내한테 읽게 하니 좋아하는군요. 힌트가 되었나 봅니다. 감사합니다.
