Geography comments: "the 2,500 ha site of the Amazonia Biodiversity Research Program/PPBio-Amazônia, in Floresta Nacional de Caxiuanä... an area of 330,000 ha in the Tocantins-Xingu interfluvium"

Environment
Habitat: tropical/subtropical moist broadleaf forest

Protection: national/state forest

Substrate: ground surface

MAT: 26.7

MAP: 1960.0

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"

Methods
Life forms: rodents,other small mammals,lizards,snakes,frogs

Sampling methods: line transect,drift fences,pitfall traps

Sample size: 399 individuals

Years: 2007

Days: 67

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"
