Habitat: tropical/subtropical dry broadleaf forest

Altered habitat: fragment

Substrate: ground surface

Habitat comments: "a forest fragment adjacent to an agricultural crop (soybean, Glycine max L. and corn, Zea mays L.)... The plot was 88.6 ha and was subjected to no-tillage farm practices with soybean-corn rotation for 10 years prior to our study. There is a 48 ha- fragment of seasonal semideciduous forest adjacent to the plot"

Life forms: ground beetles, rove beetles

Sampling methods: line transect, pitfall traps

Sample size: 1003 individuals

Years: 2004 - 2007

Days: 308

Nets or traps: 48

Net or trap nights: 14784

Basal area status: not applicable

Sampling comments: "two parallel transects of pitfall traps were installed. Transects were 10 m apart from one another. Each transect was 200 m in length, with 100 m in the crop and 100 m in the forest fragment. Four traps were 1 m apart from one another in the edge between the crop and the forest fragment and the other traps were each 10 m apart from one another. There were 48 traps in total... Sampling was done twice a month during the growing season and once a month in the off-season... for a total of 44 sampling dates... The traps were kept in the field for one week" per date
