Basis of coordinate: stated in text as range
Geography comments: "in the Devonian Scarp... 25◦20'–25◦29' S and 49◦39'–49◦42' W" and specifically in "Bugre District, São Luis do Purunã District, and Santa Rita Ranch" which are all "5–10km" apart

Climate and habitat
Habitat: tropical/subtropical savanna
Substrate: ground surface
Disturbance: agriculture, grazing, selective logging, invasive plants
WMT: 21.0
CMT: 14.0
MAP: 1600.0
Habitat comments: "subtropical, mesothermic, and constantly humid with mild summers. The mean annual temperature varies from 14◦C in the winter to 21◦C in the summer, and the mean annual rainfall averages 1600mm with no marked seasonal incidence"
habitat consists of "natural grasslands (Campos Gerais) and Araucaria Pine
Forest (Mixed Ombrophilous Forest)... Many locally important species of trees have been intensively logged and are currently rare... natural grasslands have been extensively converted to grazing fields and alternating crops, and are currently restricted to small fragments and undergoing alteration with the expansion of dispersing exotic Pinus species"
Life forms: rodents, other small mammals
Sampling methods: line transect, baited, Sherman traps
Sample size: 107
Years: 2006, 2007
Days: 48
Nets or traps: 100
Net or trap nights: 4800
Sampling comments: sampling was "from September 2006 through August 2007 (seven months concurrently with the collection of fecal samples). We used 100 Sherman live traps (50 traps with dimensions of 12cm x 14cm x 30cm and 50 traps with 8cm x 9cm x 18cm) per night. Each month, one locality was sampled during four nights of trapping, for a total of 400 trap-nights per month and 4800 trap-nights after 12 months of sampling. In each locality, we distributed the traps in two ways: (1) five parallel rows spaced every 10 meters, each row containing 10 traps spaced every five meters; and (2) one linear trail containing 50 traps spaced every ten meters. All traps were baited with banana and bacon"
