Geography comments: "The study was conducted in Reserva Natural Vale... 30 km north of the Doce River between the municipalities of Linhares and Jaguaré"
elevation 25 to 65 m
Habitat: tropical/subtropical dry broadleaf forest
Protection: nature reserve
Substrate: ground surface
MAT: 23.3
MAP: 1202.0
Habitat comments: "The climate is tropical hot and humid (Awi, following the Köppen system) with wet summers (October to March) and dry winters (April to September)... Most of the reserve is covered by dense lowland forest located on flat terrain (Tabuleiro Forest), classified as perennial seasonal forest"
Life forms: carnivores, rodents, ungulates, other large mammals, other small mammals
Sampling methods: no design, automatic cameras
Sample size: 423
Years: 2005, 2006
Nets or traps: 60
Net or trap nights: 3032
Camera type: analog
Cameras paired: yes
Trap spacing: 2.350
Sampling comments: "We used four different sampling designs over approximately 48 months: June 2005 to June 2006 (first year or year 1); June 2006 to August 2007 (second year or year 2); August 2007 to October 2008 (third year or year 3); and June 2009 to February 2010 (fourth year or year 4). Cam Trakker game cameras (Cam Trak South Inc., USA) were used in the first year; in the other years, we used Tigrinus cameras... Both brands of equipment have a passive infrared sensor and 35 mm cameras, which were loaded with 36-exposure / 200 or 400 ASA negative films... In the first year, all trapping stations contained a pair of cameras, and the units were installed facing each other. In the other years, we used only one camera trap per trapping station. No baits were used. In the first year, the reserve was divided into three areas (“north”, “south” and “west”), and sampling was conducted in each of these areas sequentially. In the remaining years, a fixed number of sampling points or trap stations were established throughout the whole area of the reserve (years 2 and 3) or in just the northern part of the reserve (year 4)... The cameras were installed on internal roads (in the first and fourth years), at 100-200 m from roads (internal edges; second year) and at 500 m from the nearest internal road (forest interior; third year)"
average spacing was respectively 2.35, 4.40, 5.14, and 2.31 km in the four years
