Ancient DNA evidence for genetic continuity in arctic dogs

The domestic dog fulfills many functions for their human companions, such as hauling, guarding, and protection. Consequently, humans have taken dogs to nearly every corner of the globe. Recent translocations of Western dogs stemming from the Victorian era dog fancy have erased some of the ancient genetic signatures of these earlier migrations. Here we used DNA of ancient and modern dogs from the North American Arctic of Alaska and Greenland to assess their genetic continuity in time and space. We successfully sequenced 23 archaeological (ca. AD 1250–1910) and recent (ca. AD 1930–1990) surface-collected Canis bone and tooth samples and compared them to 51 modern Inuit Sled Dogs and to published sequences of modern Alaskan Malamutes (and additional Inuit Sled Dogs) to test for evidence of lineage replacement or genetic continuity through time. Ancient samples from Alaska and Greenland and modern sequences from Greenland all contained a high frequency of haplotype A31, which was previously described only in modern North American Arctic dogs. Thus, A31 was a common thread tying the entire North American Arctic together prior to European colonization and, in the Eastern Arctic, indicates genetic continuity between past and present dogs as well. However, A31 is rare in modern Alaskan dogs, consistent with post-colonization replacement by Eurasian matrilines.     

Wild(er)ness: Reconfiguring the Geographies of Wildlife

Amidst millennial talk of the 'end of nature' ( McKibben 1989 ), this paper examines the precarious geographies of 'wildlife' in rather less apocalyptic terms. Animal (and plant) species designated wild are placed categorically outside the ambit of 'human society', confined to inhabiting the margins and interstices of the social world. Yet, we contend, such animals have long been routinely imagined and organized within multiple circuits of social power, which (re)configure them in important ways. These social orderings of animal life confound the moral geographies of wilderness, which presuppose an easy coincidence between the species and spaces of a pristine nature. In this paper, we employ the fluid spatial vocabulary of topology to map a more volatile and relational conception of the fabrics of wildlife. Our arguments are worked through glimpses of two historically very different social orderings of 'wild' animals – those associated with the military vernacular of the gladiatorial games of Imperial Rome, and the scientific vernacular of endangered species listing and conservation under CITES (the Convention on the International Trade in Endangered Species). These 'foldings' of wildlife in distant time/space aim to disrupt the linear historical narratives of 'civilization' and 'evolution', which consign wildlife to marginal spaces with a teleological destiny of erasure.     

Digital technologies,children and young people's relationships and self-care

Children's and young people's access to and use of digital technologies have received increasing attention in recent years. While influential UK media commentators have often focused on associated risks, researchers have taken a less exclusively problem-focused approach. Children and young people's use of, for example, social media and computer games to extend the spaces available to them in which to maintain relationships, to experiment with social identities, and to engage in an ‘economy of dignity’, however fragile, have all been highlighted. This paper builds on this work to further consider the role of such resources, accessed primarily through computers and mobile phones, as means of caring for oneself or ‘self-care’. It draws on a qualitative study which employed visual and audial methods to explore the sense of belonging (or not) of young people who have been ‘looked after’ by others than their biological parents, often in less affluent circumstances.
