. 1. Carabid beetles were sampled by means of pitfall traps on several clearcut areas and in adjacent forests. 2. A hierarchical analysis of diversity revealed a significant increase in the within‐genus component of species diversity after forest cutting. 3. This trend in intrageneric diversity was obscured, with respect to total species diversity, by a nonsignificant reduction in diversity at the generic level. 4. The increase in the within‐genus component of species diversity following forest cutting was consistent with the hypothesis that disturbance of a cornmunity can disrupt processes of competitive exclusion.
