Figure 4

Map of 31 faunistic sampling sites with the geographical subsets based on the dendogram results. Main groups are delimited with full lines (I to V and 20, 22 and 29) and inner groups with dashed lines (a to c). These groups were clustered with significant SIMPROF values (see Figure 3). Biomes are defined in a grey scale and for Brazilian states are indicated with abbreviations (see Additional file 1).
