Habitat comments: "an ‘island’ of vegetation about 250 ha in size, surrounded by pastures. It consists of remnant rain forest and interdigitated 20–25-year old stands of coffee and cacao shaded by rain forest trees and of citrus and banana groves as well as patches of pineapple, avocado and papaya" (treated as not fragmentary because forest is presumably almost connected within the tract)
Life forms: scarab beetles
Sites: 16
Sampling methods: baited, pitfall traps
Sample size: 2140
Years: 1997 - 1999
Days: 16
Nets or traps: 50
Net or trap nights: 800
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
