Potential distribution of Callistomys pictus.
(A) Potential distribution area (yellow) and core area (red) of the painted tree-rat (Callistomys pictus), as predicted by the Ecological Niche Model. These areas are defined by the "minimum training presence" and "10th percentile training presence" thresholds, respectively. (B) Map showing the gradient of climate suitability for the painted tree-rat (Callistomys pictus). The gradient from red to white represents the shift from higher to lower climate suitability for the species. The acronyms represent the names of the Brazilian states: BA—Bahia, MG—Minas Gerais.

Forested habitat and protected areas in potential distribution area.
Map of the remaining forested habitat within the potential distribution area (yellow) and core area (red) of the painted tree-rat (Callistomys pictus). The map highlights (A) selected municipalities, and (B, C, and D) all strictly protected areas (outlined in blue) within these regions. The identification numbers for the protected areas are: 1 –Wenceslau Guimarães State Ecological Station, 2—Serra do Conduru State Park, 3—Ponta da Tulha State Park, 4—Boa Esperança Municipal Natural Park, 5—Una Biological Reserve, 6—Serra das Lontras National Park, 7—Pau Brasil National Park, 8—Monte Pascoal National Park, and 9—Descobrimento National Park. The acronyms represent the names of the Brazilian states: BA—Bahia, MG—Minas Gerais.
