Climate and habitat
Habitat: tropical/subtropical dry broadleaf forest
Altered habitat: fragment
Substrate: ground surface
MAT: 26.6
MAP: 1052.0
Habitat comments: "at Rancho La Angostura... vegetation on grids was tropical deciduous forest (bordered by a small stream) in an overall landscape that was fragmented due to cultivated agriculture (mainly oranges and limes) and raising of livestock. However, the area containing the grids had native vegetation... adjacent to the Miguel de la Madrid Airport... The study area had been fragmented and used for agriculture in the past but was protected and relatively undisturbed for 30 years prior to our study. Much of the area studied had reverted to tropical moist forest intermixed with grass-dominated habitat"

Sampling comments: "This study was conducted at Rancho La Angostura, Colima (locality 14, Fig. 1) in 2006 and sites in the vicinity of the Miguel de la Madrid Airport (locality 17) in 2006 and 2007. Five trapping grids were established each year (10 total) during the annual dry season in January... Each grid consisted of 100 trapping stations (10 by 10 square grid), with stations 10 m apart. Two Sherman live traps (7.5 by 9.0 by 23.0 cm) baited with rolled oats were placed at each station, one on the ground and one elevated 1–2 m above ground on a thin plywood platform (12.5 by 34.5 cm) attached to a tree or shrub. Grids were sampled for 8 nights each; thus, overall sampling effort on the grids involved 16, 000 trap-nights"
