Sampling methods: quadrat, baited, cage traps, Sherman traps
Sample size: 124
Years: 1996 - 1997

Net or trap nights: 4185
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" with 20 "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 August 1996 and June 1997, there were 2359 trap nights on the ground, 1188 in the understorey, and 638 in the canopy, and bait was "peanut butter, corn meal, mashed banana, commercial cod liver oil and vanilla essence"
