Subsistence walrus hunting in Inuit Nunangat (Arctic Canada) and Kalaallit Nunaat (Greenland) from the 13th century CE to present
The long-term history of walrus hunting by Inuit can be characterised by the stark contrast between the innovation and venturous nature of the hunters, and the relative ecological conservatism of their prey. In this chapter, we examine several aspects of walrus subsistence hunting by Inuit from their earliest occupations in Arctic/Subarctic Canada and Greenland (beginning around the 13th century CE) to present. We focus our discussions on the intensive hunting practices of Amitturmiut of northern Foxe Basin, Nunavut, Inuit communities of the Avanersuaq region of North-West Greenland, as well as of their ancestors. We describe species-specific challenges, strategies and technologies for hunting, butchery, storage and consumption of walruses. We also provide a discussion of the position of the species within Inuit cosmology
Domestic cats (Felis catus) in Denmark have increased significantly in size since the Viking Age
The earliest finds of domestic cat in Denmark date back to the Roman Iron Age (c. 1–375 AD). Initially, cats occurred sparsely and only from the Viking Age (c. 850–1050 AD) did they become more frequent in numbers, though primarily in urban contexts and in connection with fur production. In medieval times, cats became beasts of pest control in rural settlements, manorial estates as well as in the expanding towns, where large and numerous refuse heaps attracted various rodents. To investigate size trends over time of the domestic cat (Felis catus) in Denmark, bone measurements and statistical analyses were performed on archaeological and modern material. Domestic cats were found to increase significantly in size over time since the Viking Age. Limb bones and mandibles exhibited the most significant change in increase (up to 16%), as compared to modern female cats, and tooth size the least (c. 5.5%). The most plausible explanations for such a size increase were improved living conditions caused by increased food availability and a possible shift in human usage of the cats, from a rat and mice captor to a well-fed and well-cared pet. Despite the observed increase in size, domestic cats have kept many osteological features indistinguishable from their wild progenitor
A ritual site with sacrificial wells from the Viking Age at Trelleborg, Denmark
The promontory facing Storebælt with the well-known circular Viking Age military fortress of Trelleborg erected by Harold Bluetooth in AD 980/981 seems to have been an important ceremonial space prior to the erection of the fortress and contemporary with a nearby high status settlement dated to the seventh to the eleventh century. This study presents new cross-disciplinary investigations focusing on three sacrificial well-like structures (47, 50 and 121) from the pre-Christian Viking Age at Trelleborg. Two of the sacrificial wells (47 and 121) included the only skeletal remains of four children hitherto recovered from Danish Viking Age wells. The strontium isotope results of the four children point to local provenance. However, the results of each well seem to pair up in a systematic way pointing to that the children might come from two different key surrounding areas at Trelleborg. Furthermore, the three wells contained animal remains of primarily domestic livestock partly representing consumption waste from either profane or ritual meals deriving from, for example, blót activities. Well 47 produced a young he-goat and well 121 a hindlimb of an above-average-size young horse, a large part of a young cow and a large dog. Altogether intentional offerings deposited while still enfleshed and interpreted to have served as propitiatory sacrifices to honour or appease the gods and to ensure fertility. This research provides new information that enlightens the formation processes underlying accumulation of cultural deposits in features such as ritual wells, in the period prior to Christianity

Holocene deglaciation drove rapid genetic diversification of Atlantic walrus
Rapid global warming is severely impacting Arctic ecosystems and is predicted to transform the abundance, distribution and genetic diversity of Arctic species, though these linkages are poorly understood. We address this gap in knowledge using palaeogenomics to examine how earlier periods of global warming influenced the genetic diversity of Atlantic walrus (Odobenus rosmarus rosmarus), a species closely associated with sea ice and shallow-water habitats. We analysed 82 ancient and historical Atlantic walrus mitochondrial genomes (mitogenomes), including now-extinct populations in Iceland and the Canadian Maritimes, to reconstruct the Atlantic walrus' response to Arctic deglaciation. Our results demonstrate that the phylogeography and genetic diversity of Atlantic walrus populations was initially shaped by the last glacial maximum (LGM), surviving in distinct glacial refugia, and subsequently expanding rapidly in multiple migration waves during the late Pleistocene and early Holocene. The timing of diversification and establishment of distinct populations corresponds closely with the chronology of the glacial retreat, pointing to a strong link between walrus phylogeography and sea ice. Our results indicate that accelerated ice loss in the modern Arctic may trigger further dispersal events, likely increasing the connectivity of northern stocks while isolating more southerly stocks putatively caught in small pockets of suitable habitat
Vittrup Man–The life-history of a genetic foreigner in Neolithic Denmark
The lethally maltreated body of Vittrup Man was deposited in a Danish bog, probably as part of a ritualised sacrifice. It happened between c. 3300 and 3100 cal years BC, i.e., during the period of the local farming-based Funnel Beaker Culture. In terms of skull morphological features, he differs from the majority of the contemporaneous farmers found in Denmark, and associates with hunter-gatherers, who inhabited Scandinavia during the previous millennia. His skeletal remains were selected for transdisciplinary analysis to reveal his life-history in terms of a population historical perspective. We report the combined results of an integrated set of genetic, isotopic, physical anthropological and archaeological analytical approaches. Strontium signature suggests a foreign birthplace that could be in Norway or Sweden. In addition, enamel oxygen isotope values indicate that as a child he lived in a colder climate, i.e., to the north of the regions inhabited by farmers. Genomic data in fact demonstrates that he is closely related to Mesolithic humans known from Norway and Sweden. Moreover, dietary stable isotope analyses on enamel and bone collagen demonstrate a fisher-hunter way of life in his childhood and a diet typical of farmers later on. Such a variable life-history is also reflected by proteomic analysis of hardened organic deposits on his teeth, indicating the consumption of forager food (seal, whale and marine fish) as well as farmer food (sheep/goat). From a dietary isotopic transect of one of his teeth it is shown that his transfer between societies of foragers and farmers took place near to the end of his teenage years
