Sampling comments: sampled seven times over five consecutive trapping nights: "lines were separated by 100 m... and within each line trapping points were separated by 20 m. In each capture point a live-trap (either Tomahawk... or Sherman...)... was set on the ground and an additional Sherman trap was set in tree branches or vines at breast height... Traps were baited with a mixture of banana, oat, peanut butter and bacon placed on a manioc slice"; there were 1014 trap nights in total
