Entre politique et thérapeutique : usages du rituel de la tente à sudation dans le cadre de la revitalisation culturelle amérindienne au Québec

Depuis la fin des années 1980, le phénomène de revitalisation culturelle amérindienne observé à l’échelle continentale s’est enraciné au Québec. Ce phénomène panindien, qui se définit entre autres par un mouvement de guérison dit communautaire – c’est- à-dire qui s’organise à l’intérieur-même des communautés (par opposition à ce qui vient de l’extérieur) – est caractérisé par la prise en charge des problèmes sociaux rencontrés par les populations amérindiennes. Par l’analyse du rite de la tente à sudation, une pratique emblématique de la spiritualité panindienne et du mouvement de guérison, ce mémoire explore la dualité des stratégies de relation d’aide qui y sont déployées. Pour ce faire, l’expérience en milieu carcéral et en communauté d’aînés et d’intervenants autochtones a été prise à témoin. L’enquête de terrain révèle ainsi qu’en parallèle avec la fonction de mobilisation sociale et politique associée à la revitalisation culturelle amérindienne, on assiste à une instrumentation du rituel à des fins psychothérapeutiques. Tout en s’inscrivant dans la structure cosmologique commune à plusieurs traditions orales algonquiennes, cet usage particulier de la symbolique du rituel met à jour une vision plus clinique, plus individualisée et plus dépolitisée de la guérison autochtone habituellement revendiqué dans le discours panindien.

Test of the enemy release hypothesis: the native magpie moth prefers a native fireweed (Senecio pinnatifolius) to its introduced congener (S.Madagascariensis)

Abstract The enemy release hypothesis predicts that native herbivores will either prefer or cause more damage to native than introduced plant species. We tested this using preference and performance experiments in the laboratory and surveys of leaf damage caused by the magpie moth Nyctemera amica on a co-occuring native and introduced species of fireweed (Senecio) in eastern Australia. In the laboratory, ovipositing females and feeding larvae preferred the native S. pinnatifolius over the introduced S. madagascariensis. Larvae performed equally well on foliage of S. pinnatifolius and S. madagascariensis: pupal weights did not differ between insects reared on the two species, but growth rates were significantly faster on S. pinnatifolius. In the field, foliage damage was significantly greater on native S. pinnatifolius than introduced S. madagascariensis. These results support the enemy release hypothesis, and suggest that the failure of native consumers to switch to introduced species contributes to their invasive success. Both plant species experienced reduced, rather than increased, levels of herbivory when growing in mixed populations, as opposed to pure stands in the field; thus, there was no evidence that apparent competition occurred.

The 2010 Native American and Indigenous Studies Association Conference

The 2010 Native American Indigenous Studies Conference was held at The Westin La Paloma Resort, Tucson, Arizona, USA from 20-22 May. The conference was scholarly and interdisciplinary and intended for Indigenous and non-Indigenous scholars who work in American Indian/ Native American/ First Nations/ Aboriginal/ Indigenous Studies. The 2010 gathering attracted 768 registrations from the USA, Canada, Hawaii, Mexico, New Zealand and Australia and other countries. This paper is a personal reflection and overview of the 2010 Conference.

Can hybridization cause local extinction : the case for demographic swamping of the Australian native, Senecio pinnatifolius, by the invasive, S. madagascariensis?

The outcome of interspecific hybridization between native and invasive species depends on the relative frequencies of parental taxa and viability of hybrid progeny. We investigated individual and population level consequences of hybridization between the Australian native, Senecio pinnatifolius, and the exotic S. madagascariensis, with AFLP markers and used this information to simulate the expected outcome of hybridization.A high frequency (range 8.3-75.6 %) of hybrids was detected in open pollinated seeds of both species, but mature hybrids were absent from sympatric populations indicating that sympatric populations represent tension zones. A hybridization advantage was observed for S. madagascariensis,where significantly more progeny than expected were sired based on proportional representation of the two species in sympatric populations. Simulations indicated S. pinnatifolius could be replaced in sympatric populations if hybridization was density dependent.For this native-exotic pair, prezygotic isolating barriers are weak, but low hybrid viability maintains a strong postzygotic barrier to introgression. Due to asymmetric hybridization, S. pinnatifolius appears under threat from demographic swamping, and local extinction is possible where it occurs in sympatry with S. madagascariensis.
