Table 1 Description of the selected variables to predict extinction risk transitions in terrestrial mammals.

Pressure

High human footprint extent in the matrix

Proportion of unsuitable habitat overlapping with high human footprint values in 2000.

^49,51

High human footprint extent in patches of suitable habitat

Proportion of suitable habitat overlapping with high human footprint values in 2000.

^49,51

High human footprint change in the matrix

Difference in the proportion overlap between the area of unsuitable habitat and high human footprint values during 2000 and 2013.

^49,51

High human footprint change in patches of suitable habitat

Difference in the proportion overlap between the area of suitable habitat and high human footprint values during 2000 and 2013.

Environment

Degree of habitat fragmentation

Average of the Euclidean distance from the edge to the ‘core’ (i.e. the interior) of each patch of suitable habitat.

^49,82

Degree of patch isolation

Average of the Euclidean distance between patches of suitable habitat from the edge to the ‘core’ (i.e. the interior) of each area of unsuitable habitat.

Proportion of suitable habitat

Proportion of suitable habitat within the range of each species.
