First row: change of the landscape over time (black lines = highways, black area = residential or commercial area; size of
the landscape: 4 km × 4 km = 16 km2). Only the effective mesh size behaves in a suitable way (bottom diagram). APS and
n both exhibit a jump in their values (even though the process in the landscape is continuous); DTL and nUDA100 do not
respond to the increase in fragmentation. (meff = effective mesh size, n = number of patches, APS = average patch size,
nUDA100 = number of large undissected low-traffic areas > 100 km2, DTL = density of transportation lines).
