Sampling comments: a grid with "12 traplines with eight trap stations spaced 20 m apart (n = 96 trap stations). The lines were 10 m apart and the entire 8 x 12 grid covered about 1.5 ha. We capture the animals with Sherman trap model XLF15 (10.4 x 12 x 38 cm) and home-made wire-mesh cage traps (15 x 15 x 30 cm). In each trapping session we randomly selected 66 trap stations where traps were placed on the ground. After capturing an animal, a trap was moved to another station to avoid recaptures... Additionally we placed 41 traps in the understorey (mean height of 1.7 m, range from 1.5 to 2.0 m), and 25 traps in the canopy... Mean height of the canopy stations was 10 m (range 6 to 15 m)"; there were "60% Shermans and 40% wire-mesh cage traps" on the ground and at 1.7 m but only Shermans in the canopy; trapping was between September 1995 and August 1997, there were 9782 trap nights on the ground, 5445 in the understorey, and 2134 in the canopy, and bait was "peanut butter, corn meal, mashed banana, commercial cod liver oil and vanilla essence"
