Methods
Life forms: scarab beetles
Sites: 2
Sampling methods: baited, pitfall traps
Sample size: 258 individuals
Years: 1994, 1995
Days: 40
Nets or traps: 4
Net or trap nights: 160
Basal area status: not applicable
Sampling comments: sites SB6 and SB9
"Each 2 weeks [over nine month], two [dung-baited] traps were placed separately at each sampling location, 4 m from each other, and were removed after 48 h... The total number of traps analyzed was 296" over nine sites (not just these two)
this apparently means that two traps were laid out in each of two locations for two days every two weeks over an approximate 39 week period, which comes to approximately 160 trap days
