Time and crops influences on carabids taxonomic and functional diversities whithin pesticide-free agroforestry cropping system

Influences temporelles et culturales d'un système de culture agroforestier sans pesticides sur la diversité taxonomique et fonctionnelles des carabes

Résumé

Within a pesticide-free agroforestry cropping system, carabids' communities are trapped once over years and, over weeks for one given year in order to test (1) the ageing of the cropping system, (2) the impacts of the presence of different crops and of their related agricultural practices. Main results shown that the carabids communities are different between years but no progressive diversity increase was observed. Conversely, annual climatic conditions showed significant effect on carabids abundance and limited the observation of any longitudinal trend. Then, significant differences between habitats, crops and cropping systems were observed. If diversity between closed and open-habitats was significantly different, no effect was observed between open-habitats despite the presence/absence of specific carabids species in each one. Altogether, results suggest that the SCA0PEST platform is still too young to demonstrate of the ecological connectivity enhancement potential of agroforestry, if exist.
