FIGURE 2. A) Most parsimonious area cladogram from the distribution analysis of 331 genera and 823 species of forestdependent birds from 45 localities in the Atlantic Forest and the Amazon. Values of the nodes represent the frequencies of bootstrap replicates (10,000 replicates). B) Representation of cladogram groups on the map; the localities enclosed in gray polygons correspond to group 1, and those enclosed by black polygons correspond to group 2.
