Table 2: Spatially-explicit capture-recapture density estimates
for boreal caribou in Alberta, Canada. Density estimates (D) are per
1000 km², CV(D) is the coefficient of variation (SE of density
estimate/density estimate), g0 indicates the capture probability at the
home range centre, sigma is the spatial scale parameter in metres, home
range estimates are in km², and N is the abundance over the study
area.
