Country: Brazil
State: Bahia

Coordinate: 15° 9' 0" S, 39° 13' 30" W
Basis of coordinate: stated in text as range
Geography comments: "in a landscape encompassing part of the municipalities of Una and Arataca (~60 km2; between 39°5′–39°22′ W and 15°4′–15°14′ S)... The study sites were located in farms around and between two protected areas: the Una Biological Reserve in the east, and the Serra das Lontras National Park in the west"
Climate and habitat
Habitat: tropical/subtropical moist broadleaf forest
Substrate: ground surface
MAT: 24.0
MAP: 1800.0
Habitat comments: "largely covered by mature and late secondary forest (roughly 50% of the area—see Fig. S1). The original vegetation is Southern Bahian Wet Forest... The region lacks a distinct dry season, although a warmer and rainless period occasionally occurs between December and March... Thirty-eight percent of the agroforestry mosaic outside the reserves is covered by old-growth forests that suffered different levels of selective logging in the past, and 21, 20, and 10 percent are covered by cabruca, pasture and permanent monocultures, respectively"
Life forms: carnivores, primates, rodents, ungulates, other large mammals, other small mammals

Sampling comments: "We sampled 18 sites located in nine blocks, each composed of a cabruca site and an adjacent forest site, 200–450 m apart from each other... blocks were at least 2.5 km from each other (distances varied from 2.5 to 6.2 km)... Within each block cabruca and forest sites were located to guarantee at least 200 m between them (dis- tance varied from 200 to 450 m)" (cabrucas are "cacao plantations shaded by native trees") ; "Two camera-traps (analog Trapacamera—http://www.trapacamera.com) were placed in each site, one on the ground and one in the understory (3–4 m above ground level), 50–100 m apart from each other... Data collection occurred during four sampling sessions when all sites were sampled, representing two times of the year in two different years (July–October of 2007 and 2008, and January– April of 2008 and 2009)... During each of the four sampling sessions, three cabruca-forest pairs were sampled simultaneously for four consecutive weeks and checked weekly to exchange film and re-bait"
