Patterns shown include species richness (A), number of endemic species at the Amazon basin (B) and Western Amazon sub-basin scales (C), and non-native species (D). The total number of species are indicated in the white labels, while the basin color represents the number of species per km2 (A, B) and the percentage of species with regards to the total of the Western Amazon sub-basin (C, D). Western Amazon sub-basins from north to south: Caquetá-Japurá, Putumayo-Içá, Napo, Marañón, Ucayali, Javari, Juruá, Purus, and Madeira (also see Fig. 1).
