Coordinate: 1° 57' 36" S, 51° 36' 55" W
Basis of coordinate: stated in text
Geography comments: "the 2, 500 ha site of the Amazonia Biodiversity Research Program/PPBio-Amazônia, in Floresta Nacional de Caxiuanã... an area of 330, 000 ha in the Tocantins-Xingu interfluvium"
Climate and habitat
Habitat: tropical/subtropical moist broadleaf forest
Protection: national/state forest
Substrate: ground surface
Habitat comments: "About 85% of the area is terra firme rain forest... The remaining area is igapó (flooded forest). The forest is characterized by a 30-35 m-tall closed canopy, with emergents growing to 45 m... The climate is of the Am type in the classification of Köppen... divided into a rainy season, from December to May, and a dry season, from June to November"
Life forms: rodents, other small mammals, lizards, snakes, frogs
Sampling methods: line transect, drift fences, pitfall traps
Sample size: 399
Nets or traps: 12
Net or trap nights: 804
Sampling comments: "The 100 L buckets were 820 mm deep" and there were four buckets each in three line arrays; "Buckets belonging to the same pitfall array were connected by a 10 m- long and 80 cm-high plastic drift fence. Pitfall arrays were set 150 m from one another along a transect... Each pitfall array was sampled for a total of 15 consecutive days in January-February, 17 consecutive days in March-April, 18 consecutive days in June-July, and 17 consecutive days in November"
