Sampling comments: "dung beetles were sampled in 16 locations... At each location... we set up 50 baited pitfall traps... Dung beetles were sampled [for a single day each] in February–March, May–June, and September–October in the 3-year period for 288 24-h periods" (apparently meaning 288 across three categories of sites including this one); however, the authors also say that samples were "based on 50 baited pitfall traps at 16 locations in each habitat for one 24-h period", so the latter math is used
