TL;DR: The 4 e rapport du Groupe intergouvernemental d'experts sur l'evolution du climat (Giec) as discussed by the authors proposes an evaluation remise a jour des elements scientifiques, techniques and socio-economiques permettant une meilleure comprehension du changement climatique, de ses impacts potentiels and des possibilites d'adaptation and de mitigation.
Abstract: Le 4 e rapport du Groupe intergouvernemental d'experts sur l'evolution du climat (Giec), recemment paru, propose une evaluation remise a jour des elements scientifiques, techniques et socio-economiques permettant une meilleure comprehension du changement climatique, de ses impacts potentiels et des possibilites d'adaptation et de mitigation. Il s'appuie sur des simulations numeriques des climats preindustriels des xx e et XXI e siecles, realisees de maniere concertee par les principaux groupes de recherche sur le climat de par le monde. Nous proposons ici une synthese du travail realise sur ces simulations par la communaute de recherche francaise dans le cadre du projet national Escrime, en montrant en particulier comment, selon ces etudes, la cryosphere, la circulation thermohaline et le climat des regions polaires pourraient evoluer au cours du XXI e siecle dans le cadre du rechauffement climatique.

TL;DR: The structure of assemblages of dung beetles as well as their species composition and diversity were compared between two sites on both sides of the Mediterranean Sea and it was demonstrated that autumn-winter was the most constraining season in FR.
Abstract: Quantification of the species richness and diversity is important when comparing sites; these variables are influenced by local and regional factors. The structure of assemblages of dung beetles as well as their species composition and diversity were compared between two sites on both sides of the Mediterranean Sea (France FR and Tunisia TN). From a total of 132 traps, 15,778 specimens were collected belonging to 86 species (46 in FR vs. 40 in TN). Species composition varied highly between FR and TN (only 10 species in common). The temporal occurrence of Aphodiidae and Scarabaeidae showed different patterns due to several factors: phenology of species, geographical distribution and local ecological requirements. When quantifying the beta diversity, the turnover of species was for almost cases higher within the same season than between seasons. Moreover, seasonal turnover was different at both sites. Evenness and rank-abundance analyses demonstrated that autumn-winter was the most constraining sea...
