Environment
Habitat: tropical/subtropical dry broadleaf forest
Altered habitat: cropland
Substrate: ground surface
Habitat comments: "This area was about 2 km distant from Experimental Area 1, and consisted of a 6-ha fragment of semi- deciduous forest, and a 12-ha field in which conventional tillage was used to produce a summer crop of soybean and winter crop of corn." (P. 502)
Methods
Life forms: spiders,ants
Site length: 200
Sampling methods: line transect,pitfall traps
Sample size: 12685 individuals
Years: 2005, 2006, 2007
Days: 308
Nets or traps: 48

Sampling comments: "Insects were sampled with pitfall traps, each consisting of a plastic cup, 8 cm diam and 14 cm high. Two parallel 200-m transects separated 10 m apart were installed in each experimental area. Each transect spanned the habitat interface with 100 m in the forest fragment and 100 m in the field devoted to the production of soybean and corn... 48 traps spaced 10 m apart were set in each area with 24 in the forest fragment and 24 in the cultured area... samples were taken... from 9 Apr 2005 to 26 Apr 2007, totalling 44 sampling dates. The traps remained installed in the field for 1 wk"
