Figure 1

Location of the Reserva Florestal Adolpho Ducke (RFAD) in relation to the city of Manaus, Amazonas, Brazil (in pink), and spatial distribution of our sampling in the 8 × 8 km trail grid. Squares located every km along the east-west trails represent the place where lines of 20 mist-nets and forest plots were located. Dashed lines of 1 km represent the location of the acoustic surveys. Squares in yellow represent plots located in the western basin; squares in red represent plots located in the eastern basin. Squares in grey represents plots located along the central plateau, and were not used in the basin analysis.
