  1. Home ranges were estimated at both the 95 and 50 quantiles via autocorrelated KDE and conventional KDE. Note the larger range estimates and wider confidence intervals of the AKDE method, which accurately accounts for (i) autocorrelation between relocations; (ii) the number of range crossing events observed; and (iii) the error associated with each fix
