Climate and habitat
Habitat: tropical/subtropical dry broadleaf forest
Altered habitat: secondary forest
Substrate: ground surface
WMT: 29.0
CMT: 12.0
MAP: 1119.0
Habitat comments: primary "Atlantic forest" on the other side of a rain shadow and "with a distinct dry season... the vegetation possesses a greater percentage of tree species showing partial deciduity during the dry season"

Methods
Life forms: rodents, other small mammals
Site length: 300.000
Site width: 200.000
Sampling methods: quadrat, baited, cage traps, Sherman traps, Tomahawk traps
Sample size: 157
Years: 1985 - 1986
Days: 85
Nets or traps: 112
Net or trap nights: 9520
Sampling comments: "three 300 meters long parallel lines were cut" and "separated by 100 meters" yielding a trapping area of 6 ha; there were "16 trapping stations located 20 meters apart" on each line (total 48) and each trap station had one Tomahawk trap "on the ground" and "every other station" had one "above ground on branches or vines" plus a Sherman trap "with alternation of ground and tree traps", plus there were "the two outermost transect lines had, at every other station, a large... wire home-crafted live trap"; thus, there was "a total of 112 permanent based traps"
trap sessions were five nights long and there was one session per month for 17 months for a reported total of 9520 trap nights
