Paysage et traits d'histoire de vie chez les coléoptères carabiques

Abstract : The landscape impact on community was studied about its specific composition and Life History Trait (LHT) distribution. However landscape characteristics also influence species evolution and may select for specific traits. Traits selected at the species scale and those selected at the community scale could be similar. During our study, we were interested by the link between landscape impact on community and on species. Various Life History traits were referenced for some species and individual morphological measures were collected for nine dimorphic species. An RLQ analysis has been done to show up the link between landscapes factors and LHT of the community. It appears that some traits are strongly linked to the landscape diversity. Existence of a morphological differentiation between individuals from different sites and the link between inter and intra-specific variation, specifically the individual length were studied. Preliminary analysis suggests that wing morphology seems more correlated to inner species parameters than the community characteristics.
