Habitat comments: "an 8,000 ha private ranch managed for artificially irrigated crop production (rice, maize, bean and soybean). About 70% of its area consists of pristine Cerrado sensu lato physiognomies, ranging from 'cerradäo' (dense savanna woodland), to open scrublands and grasslands" and sampling was "mainly within forested areas along the mid-Araguaia riverbanks"
climate data are for the middle Araguaia River basin and are from Sawakuchi et al. (2013, Open Journal of Forestry)

Life forms: rodents,other small mammals

Sampling methods: line transect,drift fences,pitfall traps,Sherman traps,Tomahawk traps

Sample size: 116 individuals

Years: 2007, 2008

Net or trap nights: 4424

Sampling comments: three sampling points, with each consisting of "a transect of sixteen 30 L pitfalls with drift fences; a transect with ten 60 L pitfalls with drift fences (except at FLV, where burying large pitfalls in waterlogged soil was unfeasible); a mixed transect with 22 Sherman traps (45 x 12.5 x 14.5 cm) and ten Tomahawk traps (45 x 21 x 21 cm) placed on the ground; and a mixed transect with four Sherman traps and four Tomahawk traps placed in the understory... Four additional transects with 22 Sherman and ten Tomahawk traps were established near irrigation channels and in the Cerrado sensu strictu matrix at FLV, which were sampled only during one seven-night period"
