Measurements of area use by badgers obtained using different methodologies. A shows measurements of area use by all seven badgers obtained via 95% Kernel Density Estimate when calculated using GPS data (‘GPS KDE’), and GPS-enabled Dead-Reckoned data (‘DR KDE’), and via 95% Minimum Convex Polygon when calculated using GPS data (‘GPS MCP’) and GPS-enhanced dead-reckoned data (‘DR MCP’) across all nights of collaring. The black horizontal line represents the median, with the upper and lower quartiles represented by the top and bottom of each bar, respectively. The whiskers (vertical black lines) extend to the smallest and largest values no more than 1.5 times the inter quartile range. Outlying values beyond the extent of the whiskers are denoted as individual points. B illustrates differences in area use for one individual badger as determined using 95% Minimum Convex Polygons calculated using (i) GPS data (represented by light grey shading) and (ii) GPS-enhanced dead-reckoned data (denoted as a black hatched area) which measured 0.153 and 0.168 km², respectively. C shows 95% Kernel Density Estimates for the same individual calculated using (i) GPS data (light grey shading) and (ii) GPS-enhanced dead-reckoned data (black hatched area) which measured 0.291 and 0.120 km², respectively
