Country: Brazil
State: Pernambuco

Coordinate: 8° 29' S, 37° 20' W
Basis of coordinate: stated in text
Geography comments: the park "covers 62, 294 ha"
altitude 600 to 1000 m
Climate and habitat
Habitat: tropical/subtropical dry broadleaf forest
Altered habitat: fragment
Protection: national/state park
Substrate: ground surface
Disturbance: grazing, selective logging
MAT: 23.0
MAP: 790.0
Habitat comments: "natural Caatinga vegetation" with "distinct tropical dry forest phytophysiognomies, from shrubby vegetation to forests"
"mean annual temperature of 23ºC and mean precipitation ranging from 480 to 1100 mm"
"The best-preserved area (24, 597 ha of continuous forest) is located in the western portion of the Park... However, different chronic anthropogenic disturbances (e.g. overgrazing and firewood extraction) has been reported as significant drivers of habitat degradation in the entire Park"
Life forms: carnivores, rodents, ungulates, other large mammals, other small mammals
Sampling methods: no design, automatic cameras
Sample size: 823
Years: 2017, 2018
Seasons: dry
Nets or traps: 18
Net or trap nights: 2340
Camera type: digital
Cameras paired: no
Sampling comments: "Distances between landscape centroids varied from 2 km to 18.5 km (mean: 8.5 km)" but this refers to all pairs of cameras, not adjacent ones, which appear to be mostly 2 km apart based on Fig. 1
"we installed a camera trap (Bushnell Nature-view) at the centroid of each landscape... We sampled the 18 landscapes simultaneously and continuously over 5 months between October 2017 and February 2018, which encompasses the dry season... To obtain independent records, we used a temporal criterion to exclude continuous records of the same species during one-hour interval after its first record... we included all terrestrial and scansorial species that could be identified through camera trap, excluding bats, small rodents and marsupials" but rodents and marsupials are listed anyway
