This project investigates the effects of construction of a corridor through previously intact mature forest on carabid assemblages in that forest. In 1999, a corridor was constructed through previously minimally-disturbed mature forest in a hilly area of southeastern Ohio. The study site was in oak-hickory forest along a single ridgetop. Changes in carabid assemblages in and near the corridor were monitored for two years (2001 and 2002) as ecological succession proceeded. Shifts in the composition of these assemblages reveal patterns of insect succession in ridgetop oak-hickory forests. This research may also provide a method to evaluate changes occurring in terrestrial microhabitats in this forest type as succession proceeds. The results of this study may be used as a model of carabid succession in the terrestrial ecosystems of hilly areas in southeastern Ohio.
