Altered habitat: fragment
Protection: unprotected
Substrate: ground surface
MAT: 24.1
WMT: 25.6
CMT: 21.9
MAP: 2600.0
Habitat comments: "Twenty-one forest fragments ranging from two to 14, 480 ha... All were surrounded by pasture and with few emergent trees due to intense selective logging in the past"
based on Michalski et al. (2007, Biotropica), the median fragment size is 26 ha
MAP 2500 to 2700 mm according to the text; MAT, CMT, and WMT are based on Vourlitis et al. (2004, Ecological Applications) and applies to a site about 50 km NNE of Sinop
Life forms: rodents, other small mammals
Sites: 21
Sampling methods: line transect, baited, Sherman traps
Sample size: 271
Years: 2009
Days: 210
Net or trap nights: 6300
Sampling comments: each fragment was "sampled for 10 consecutive days" with anywhere from one to three "ground-level grids" each of which consisted of "three parallel transects, each transect was 100 meters long and separated by 50m from the next. A trapping point was established every 20 meters along each transect, totalling five trapping points on each of the three transects" with one peanut butter- and banana-baited Sherman trap per point
