Low regional diversity of late cave bears mitochondrial DNA at the time of Chauvet Aurignacian paintings

The Chauvet-Pont d'Arc and Deux-Ouvertures caves, located along the Ardèche River (France), contain abundant remains of the extinct cave bear (Ursus spelaeus). Because they also display a variety of Palaeolithic anthropogenic evidences, such as the earliest charcoal drawings recorded to date (Chauvet-Pont d'Arc), and delicate engravings (Deux-Ouvertures), they offer the opportunity of studying the interaction between animals and human beings during a key period for Pleistocene species extinctions. We characterized cave bear specimens from these two sites by radiocarbon dating, stable isotopes, and mitochondrial DNA analysis. In Chauvet-Pont d'Arc, we obtained radiocarbon ages that ranged between 29,000 and 37,300 years before present (BP). The Deux-Ouvertures cave bear specimens clustered to the bottom of this time frame, returning radiocarbon ages of 27,440–30,220 years BP. Cave bear nitrogen isotope values were all compatible with a vegetarian diet. Mitochondrial DNA analysis, carried out on a highly variable domain of the control region, evidenced only two cave bear haplotypes, including a new haplotype, and a common one which largely predominated. We detected both haplotypes in Chauvet-Pont d'Arc, but only recorded the predominant one in the Deux-Ouvertures Cave. Our data put forward the surprising observation that cave bears inhabited Ardèche over a short period of time, from about 37,000 to 27,400 years BP. They were notably present during the first (Aurignacian) phase of human intrusions in Chauvet-Pont d'Arc, 30,000–32,000 years BP. This points to the possible competition for cave sites, presumably on a seasonal scale considering the cave bear habit for hibernation. During this time period, the small number of haplotypes is at variance with the extensive genetic diversity reported elsewhere for much more ancient specimens.     

Sheepology: The Postcolonial Politics of Raceless Racism in Switzerland

Discussing racism and its colonial genealogy remains difficult in contemporary Switzerland. This article addresses the politics of racism's name-ability at the crossroads of studies of ‘postcolonial Switzerland’ and ‘raceless racism’ in continental Europe. The former highlight Switzerland's self-conception as outside colonialism. The latter emphasize the complexities of Euro-racism, in particular its production through the absence of explicit racial references. Drawing on postcolonial discourse-analytic methodology, I explore the famous case of the ‘sheep poster’ that supported the far right-wing Swiss People's Party campaign in 2007 and triggered an important controversy around legitimate public images of ‘Swissness’ and ‘difference’. The first section analyses the (untold) history of colonial racialised discourses that are conveyed by the poster. The second and third sections comprise a discourse analysis of the public claims that were expressed by various actors against or in defence of the poster. I show that the controversy consisted of a struggle between three antagonistic articulations of ‘Swissness’ and ‘difference’, namely between an antiracist discourse, and anti-exclusionary discourse, and defensive interventions. As the two latter discourses became hegemonic at the expense of the anti-racist critique, this struggle reasserted and renewed a regime of raceless racism, revealing both specificities and commonalities between the Swiss case and the broader context of postcolonial Europe.     

Un classement multicritère des villes du québec pour favoriser la prise en compte de leurs différences

When it comes to making planning and development decisions, the concepts of small, medium-sized, or large cities are sometimes used to adapt public policies and instruments, or even to highlight challenges that are specific to certain categories of city. In this article, we take a look at the various dimensions that can be used to characterize cities, so as to empirically test a multi-criteria approach and build a typology of Quebec cities. Using an ascending hierarchical classification, we derive 11 classes of cities, whose conceptualization and graphic representation enable us to highlight their role and, in part, to localize their polarized area. This article complements and adds to works undertaken by other researchers over the last 20 years. Although it does not aim to propose specific changes to public policies and instruments, this article may serve to inform public decision makers in the development of such policies and instruments, and to enrich academic debates on the nature of small and medium-sized towns in particular.
