Geographic Distribution of Chagas Disease Vectors in Brazil Based on Ecological Niche Modeling

Table 1

Presence/absence matrix of triatomine species in Brazilian states. The rows represent the 62 triatomine species and columns the 27 Brazilian states. Presence records are represented by black cells in the matrix; white cells indicate that the species is probably absent in the state. The last row (labelled “Total”) indicates the total number of species recorded in each state, and the last columns indicate the total number of data points recorded and the biomes where each species occurs.
