Table 1 Environmental variables used to model the potential distribution of Lutzomya (N.) whitmani and American cutaneous leishmaniasis in Brazil. All variables were resampled from original resolution to 0.04° (~5 km), using the average value of all involved pixels, where the source pixels are covered by the target pixel
