Identifying adaptive genetic variation is a challenging task, in particular in non-model species for which genomic information is still limited or absent. Here, we studied distribution patterns of amplified fragment length polymorphisms (AFLPs) in response to environmental variation, in 13 alpine plant species consistently sampled across the entire European Alps. Multiple linear regressions were performed between AFLP allele frequencies per site as dependent variables and two categories of independent variables, namely Moran's eigenvector map MEM variables (to account for spatial and unaccounted environmental variation, and historical demographic processes) and environmental variables. These associations allowed the identification of 153 loci of ecological relevance. Univariate regressions between allele frequency and each environmental factor further showed that loci of ecological relevance were mainly correlated with MEM variables. We found that precipitation and temperature were the best environmental predictors, whereas topographic factors were rarely involved in environmental associations. Climatic factors, subject to rapid variation as a result of the current global warming, are known to strongly influence the fate of alpine plants. Our study shows, for the first time for a large number of species, that the same environmental variables are drivers of plant adaptation at the scale of a whole biome, here the European Alps.

The origins of biblical historiography may be dated to the end of the VIIth c. and linked to those of the deuteronomic school itself. In order to justify Josiah's politics, his scribes elaborated a collection of texts (Deut, Josh, Kings, a vita Mosis in Gen-Nb) which were widely inspired by Assyrian ideology. During the Babylonian exile, this literature underwent a transformation: the new created « Deuteronomistic History, (Deut-2 Kings) converted propaganda into theodicee. The Deuteronomists were still at work in the Persian period as can be seen in numerous texts in Deut-2 Kings, as well as in the edition of the prophetic corpus. From now on, dtr ideology was centered on three points: the restauration by law, the end of prophecy and the need to separate Israel from the « others » (cf. EsdNeh). But the Persian period was also the, time of compromise. The Pentateuch was made by putting together dtr and priestly ideologies, « autochtonous » and « exodic » views about the origins of Israel.
