Different estimators (x-axis) lead to very different home-ranges sizes (HRS; A). The individual sex is indicated by the symbol (triangles for male and circles for female). An advantage of autocorrelated Kernel Density Estimates (aKDE) is that they provide individual confidence intervals (small vertical lines in A and B). Population- level estimates were obtained by averaging individual estimates of natural log home-range area (B) and calculating t-based confidence intervals for the mean (B). Finally, we calculated the difference between male (m) and female (f) mean log home-range size (C). The horizontal dashed line at 0, indicates no difference between mean male and female home-range size. For panels B and C we calculated 95% t-based confidence intervals.
