Habitat: tropical/subtropical dry broadleaf forest

Substrate: ground surface

MAT: 22.0

MAP: 975.0

Habitat comments: "a 7700 ha private reserve of native vegetation... Trapping was conducted in the 'Cordilheiras', which are sinuous remains of paleo-levees several kilometers in length about 100 m wide, reaching 1-2 m above the surrounding bodies of water and seasonally inundated plains. These elevations are not subject to flooding and are covered by dense, semi-deciduous forest vegetation... The climate is sub-humid tropical, characterized by dry winters and rainy summers"
climate data are for "the lakes of Pantanal" and are from Furquim et al. (2008, Clays and Clay Minerals): MAP 850 to 1100 mm

Life forms: rodents,other small mammals

Sampling methods: line transect,baited,Sherman traps,Tomahawk traps

Sample size: 615 individuals

Years: 2003, 2004

Days: 49

Nets or traps: 440

Net or trap nights: 21560

Sampling comments: "Capture-mark-recapture sessions were undertaken for seven consecutive nights on four plots during 2003 and 2004. In plots 1 and 2, trapping sessions occurred every three months. In plots 3 and 4, traps were placed every three months in 2003 and every six months in 2004. Each plot consisted of four line transects, three inside the forest and one on the forest edge. In each plot, transects were randomly marked, respecting a distance of 200 m apart from each other. The distance between plots was 2 km. Each transect had 10 trapping stations 20 m apart. Two traps were placed at each station next to each other, one Tomahawk® (model 201, 40.6 x 12.7 x 12.7 cm) and one Sherman® (model XLK 7.6 x 9.5 x 30.5 cm). In the forest transects, one additional trap was placed in a tree at each station, a Tomahawk® trap for odd-numbered stations and a Sherman® trap for even-numbered stations. Traps were baited with a mixture of banana, peanut butter, oatmeal and bacon and checked daily every morning."
