Environment
Habitat: tropical/subtropical dry broadleaf forest
Altered habitat: fragment
Substrate: ground surface
MAT: 26.0
MAP: 1285.0
Habitat comments: "moist semievergreen forest... The majority of the canopy appeared to be deciduous"
the "study area in the forest was a 4-ha plot" that "is the most extensive portion of the forest" (so it is clearly a fragment)
MAT and MAP (range 103 to 154 cm) stated in text; "daily average range" is 11.5
