Figure 1.
Distribution of remaining forest patches across the northern Atlantic Forest study region showing all surveyed forest patches.
Figure 2.
Size distribution of all forest patches surveyed (left, N = 196) or not surveyed (right, N = 613,997 patches >0.25 ha) within the entire study region (∼252,669 km2).
Numerical representation of different-sized patches are expressed in terms of proportions of the total.
Figure 3.
Species-area relationships (SARs) for (a) species richness, (b) a measure of total biomass, and (c) a measure of total species vulnerability for 18 mammal species surveyed at 196 forest patches of the Atlantic forest of northeastern Brazil.
Solid circles (and corresponding regression lines and 95% confidence intervals) indicate the five existing strictly protected forest areas in the entire study region, for which intercepts were clearly higher. All other data points (gray circles) represent unprotected forest sites.
Figure 4.
Levels of forest patch occupancy for 18 mammal species surveyed throughout the Atlantic Forest study region of northeastern Brazil.
Species are ordered top to bottom according to increasing level of patch occupancy. Dark-gray bars indicate the proportion of all 196 forest patches occupied by each species (see Table 1 for full Latin and English names), and solid circles indicate the aggregate forest area contained within all occupied patches.
