Site fidelity and area size of seasonal home ranges of male walruses in Svalbard, Norway. (a) Spatial consistency measured as the year-to-year overlap of 50% and 95% utilization distributions using the PRH index. The number of overlap values included in each boxplot is indicated above each box. The ALL value is based on the mean of individuals (with the number of individuals included on top). (b) Area of 50% utilization distributions for summer (red) and winter (blue). Two boxplots are given per ID if incomplete seasons could be excluded. Hence, in the first boxplot all seasons are included and in the second only complete seasons if min. one full season remained. Numbers of seasons in each animal’s data set are given above each box.
