Sample size: 1051

Sampling comments: 10 baited pitfall traps "spaced 20 m apart along a linear transect" variously baited with human or howler monkey dung or with carrion; "Each study was carried out over a 24-h period with faeces and a 48-h period with carrion... We ran the trapping programme with 40% carrion (n = 150 trap days), 30% human faeces and 30% howler dung in February, April, May and October between 1995 and 2002" (i.e., 10 traps x 3 days x 4 months x 8 years), but each sample corresponds to a 4 hour sampling period out of a 24 hour day, so the total number of sampling days is 96/6
