Genetic Diversity and Relationships of Tlingit Moieties
The Tlingit from Southeast Alaska belong to the Northwest Coast cultural tradition, which is defined by regionally shared sociocultural practices. A distinctive feature of Tlingit social organization is the matrilineal exogamous marriage system among clans from two opposite moieties: the Raven/Crow and Eagle/Wolf. Clan and moiety membership are determined by matrilineal descent, and previous genetic studies of Northwest Coast populations have shown that there is a relationship between clan membership and genetic variation of matrilines and patrilines. To further understand this association, mitochondrial DNA (mtDNA) sequences from the Tlingit (n=154) are examined. By comparing mtDNA with moiety membership information, we explore the impact of marriage traditions among the Tlingit with their observable genetic variation. At the genetic level, the results support cultural persistence of Tlingit maternal moiety identity despite the negative impacts of European colonization. Our study additionally illustrates the relevance of data derived from Tlingit oral traditions to test hypotheses about population history on the Northwest Coast

Sustainable Biomass Energy and Indigenous Cultural Models of Well-being in an Alaska Forest Ecosystem
Oil-dependent indigenous communities in remote regions of Alaska and elsewhere are facing an unprecedented crisis. With the cost of fuel and transport skyrocketing, energy costs are crippling local economies, leading to increasing outmigration and concern for their very existence in the future. What can be done to address this energy crisis, and promote energy security, sustainability and resilience in rural forest communities? We examine the potential of developing a sustainable biomass-energy industry in Southeast Alaska, home to nearly 16,000 Alaska Natives in a dozen rural and two urban communities within the United States' largest national forest: The Tongass. Although the potential for biomass energy has long been touted, realization of the opportunity has been catalyzed only recently as part of a model of sustainable development being enacted by the region's largest Native corporation, Sealaska, and its subsidiary, Haa Aaní ("Our Land") L.L.C. In this paper we examine the unique nature of Alaska Native corporations and their potential as engines of sustainable development, particularly through Sealaska's emerging cultural model of sustainability in relation to social-ecological well-being. We assess the economic, ecological, and atmospheric emissions parameters of a wood-biomass energy industry at various scales according to the "triple bottom line" of sustainability. Finally, we address what additional policy and support measures may be necessary to nurture the successful transition to biomass energy at a sustainable scale to support rural indigenous communities, a more resilient, renewable energy system, and a lower carbon footprint
Association between gene methylation and experiences of historical trauma in Alaska Native peoples
Abstract Background Historical trauma experienced by Indigenous peoples of North America is correlated with health disparities and is hypothesized to be associated with DNA methylation. Massive group traumas such as genocide, loss of land and foodways, and forced conversion to Western lifeways may be embodied and affect individuals, families, communities, cultures, and health. This study approaches research with Alaska Native people using a community-engaged approach designed to create mutually-beneficial partnerships, including intentional relationship development, capacity building, and sample and data care. Methods A total of 117 Alaska Native individuals from two regions of Alaska joined the research study. Participants completed surveys on cultural identification, historical trauma (historical loss scale and historical loss associated symptoms scale), and general wellbeing. Participants provided a blood sample which was used to assess DNA methylation with the Illumina Infinium MethylationEPIC array. Results We report an association between historical loss associated symptoms and DNA methylation at five CpG sites, evidencing the embodiment of historical trauma. We further report an association between cultural identification and general wellbeing, complementing evidence from oral narratives and additional studies that multiple aspects of cultural connection may buffer the effects of and/or aid in the healing process from historical trauma. Conclusion A community-engaged approach emphasizes balanced partnerships between communities and researchers. Here, this approach helps better understand embodiment of historical trauma in Alaska Native peoples. This analysis reveals links between the historical trauma response and DNA methylation. Indigenous communities have been stigmatized for public health issues instead caused by systemic inequalities, social disparities, and discrimination, and we argue that the social determinants of health model in Alaska Native peoples must include the vast impact of historical trauma and ongoing colonial violence
Patterns of Admixture and Population Structure in Native Populations of Northwest North America
The initial contact of European populations with indigenous populations of the Americas produced diverse admixture processes across North, Central, and South America. Recent studies have examined the genetic structure of indigenous populations of Latin America and the Caribbean and their admixed descendants, reporting on the genomic impact of the history of admixture with colonizing populations of European and African ancestry. However, relatively little genomic research has been conducted on admixture in indigenous North American populations. In this study, we analyze genomic data at 475,109 single-nucleotide polymorphisms sampled in indigenous peoples of the Pacific Northwest in British Columbia and Southeast Alaska, populations with a well-documented history of contact with European and Asian traders, fishermen, and contract laborers. We find that the indigenous populations of the Pacific Northwest have higher gene diversity than Latin American indigenous populations. Among the Pacific Northwest populations, interior groups provide more evidence for East Asian admixture, whereas coastal groups have higher levels of European admixture. In contrast with many Latin American indigenous populations, the variance of admixture is high in each of the Pacific Northwest indigenous populations, as expected for recent and ongoing admixture processes. The results reveal some similarities but notable differences between admixture patterns in the Pacific Northwest and those in Latin America, contributing to a more detailed understanding of the genomic consequences of European colonization events throughout the Americas
Ancient individuals from the North American Northwest Coast reveal 10,000 years of regional genetic continuity
Recent genomic studies of both ancient and modern indigenous people of the Americas have shed light on the demographic processes involved during the first peopling. The Pacific Northwest Coast proves an intriguing focus for these studies because of its association with coastal migration models and genetic ancestral patterns that are difficult to reconcile with modern DNA alone. Here, we report the low-coverage genome sequence of an ancient individual known as "Shuká Káa" ("Man Ahead of Us") recovered from the On Your Knees Cave (OYKC) in southeastern Alaska (archaeological site 49-PET-408). The human remains date to ∼10,300 calendar (cal) y B.P. We also analyze low-coverage genomes of three more recent individuals from the nearby coast of British Columbia dating from ∼6,075 to 1,750 cal y B.P. From the resulting time series of genetic data, we show that the Pacific Northwest Coast exhibits genetic continuity for at least the past 10,300 cal y B.P. We also infer that population structure existed in the late Pleistocene of North America with Shuká Káa on a different ancestral line compared with other North American individuals from the late Pleistocene or early Holocene (i.e., Anzick-1 and Kennewick Man). Despite regional shifts in mtDNA haplogroups, we conclude from individuals sampled through time that people of the northern Northwest Coast belong to an early genetic lineage that may stem from a late Pleistocene coastal migration into the Americas

ANTHROPOLOGY AND PUBLIC POLICY IN ALASKA: RECENT POLICY RELATED TO LEGAL SYSTEMS NATIVE SUBSISTENCE AND COMMERCIAL FISHERIES
The past and potential contributions of anthropology to public policy have been described andlor argued for by numerous writers in the past decade, but the primary application and concern have been at the national and international levels. The present paper continues this discussion, but focuses on state-level policy in Alaska. The work of three Alaskan anthropologists is presented; they have made significant contributions to policy in the areas of law, Native Alaskan subsistence rights and fisheries management. Their work is evaluated in the context of a five-step model for conducting policy analysis which begins with the assessment of policy-making environments and ends with an evaluation of policy alternatives. The primary policy concerns of the anthropologists discussed involved the traditional research focus of anthropology, Native Alaskans; however, the tools they employ and background they bring to their work, the specific kinds of policy issues and problems confronted, are not as traditional. One of the anthropologists discussed is atlingit Indian completing doctoral studies at Harvard University, another is a lawyer-anthropologist, and the third is highly trained in biological and economic theory as well as computer technology. It is argued that the "hyphenated" anthropologist, at least as exemplified in the cases discussed, is most readily equipped to make policy relevant contributions.
