In model acronyms, "ne" denotes the negative-exponential model, "ar" denotes the availability radius model, "hr" denotes that a distance to home range center term,
hr, is included and "hab" denotes intercepts, j, for each habitat type are included, with subscripts: sec = secondary habitat, marg = marginal habitat, sand = sand mining revegetation, clear = cleared land, other = other vegetation. The intercept for primary habitat is fixed at zero.
