Characteristics of dispersal in wolverines
We studied patterns of dispersal and sizes of home ranges of juvenile wolverines (Gulo gulo). Mean dispersal age was 13 months for both male (n = 11) and female (n = 9) wolverines. Females displayed more variation in dispersal age (726 months) than males (718 months). Of the animals used in the di...

We studied patterns of dispersal and sizes of home ranges of juvenile wolverines (Gulo gulo). Mean dispersal age was 13 months for both male (n = 11) and female (n = 9) wolverines.
