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"
Life forms: scarab beetles

Sampling methods: baited, pitfall traps

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
