Résumé :
|
In a temperate, deciduous even-aged forest context we tested two main hypotheses related to the short-term and mid-term response of carabid communities to regeneration felling: 1. The 'perturbation hypothesis': species abundances change in opposite directions between species shortly after felling (maximum 20 years). 2. The 'succession hypothesis': species abundances peak, or bottom out, at different silvicultural stages depending on the species (up to 100 years). Our results confirmed the two hypotheses. Moreover, the species that were significantly affected negatively in the short term by the regeneration felling (especially Carabus nemoralis and C. violaceus) increased in abundance along the first 100 years of the silvicultural cycle, suggesting that the regeneration felling did not have a detrimental effect on carabid communities on a 100-year time scale.
