Methods
Life forms: rodents,other small mammals
Site length: 300
Site width: 200
Sampling methods: quadrat,baited,cage traps,Sherman traps,Tomahawk traps
Sample size: 157 individuals
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
