This special issue of Cross-Cultural Research presents four papers each of which in their own way addresses the question of how Arctic populations tackle the high levels of unpredictability and risk associated with their environment. It takes as a starting point the evidence for and against aspects of disequilibrium between humans, animals, and their environment. The authors consider both contemporary and historical Indigenous Arctic populations and the dynamics of human–animal relations in the context of an ever-changing socioecology of the Arctic. Three overarching sources of disequilibrium are identified: (a) disruption in existing ecological networks due to climate and environmental upheaval, (b) effects of sociopolitical change (including migration and disease), and, finally, (c) changes to subsistence strategies. Based on contemporary field studies from across the Arctic, including the Ust'-Avam and Samoyed from the Taimyr Region in Russia, Sami in Finland, Yukagir and Chukchi from Siberia, and the historic Thule community from Greenland, the authors illustrate how, despite apparent disequilibria, there is nevertheless notable resilience evident in the coupling of human-environmental systems. Documenting past and present changes in local livelihoods, subsistence patterns, and sociocultural practices helps us understand the wider context in which these cultures persist. It also allows us to explore what factors are significant in supporting the long-term resilience of Indigenous communities, especially in the context of challenges, such as high levels of addiction, depression and suicide, facing contemporary arctic societies.

Institutions are influential in mediating the impact of adaptation initiatives at the local level, yet there are disconnects between the goals of multi-scale planning initiatives and community priorities. Research to address this challenge primarily focuses on reform to formal institutions in environmental governance. Meanwhile, knowledge of the specific role informal institutions play in governance processes remains limited. This study increases understanding of the interactions between informal institutions and adaptation using a case study of the Native Village of Wainwright on Alaska's North Slope. Qualitative contextual analysis was employed to identify patterns of informal institution and adaptation associations in historic and contemporary situations in Wainwright. The Adaptation Institutional Analysis Framework developed in this paper extends Elinor Ostrom's Institutional Analysis and Development Framework and is used as a tool to analyse and describe these dynamics. Four primary findings resulted from this analysis (1) identification of informal institutions that have a bearing on adaptation to environmental change and adaptive capacity in Wainwright, (2) insight into how the identified institutions relate to each other and to different aspects of local adaptation, (3) identification of changes in informal institutions that have occurred over time and the potential implications of these changes for local adaptive capacity, and (4) potential opportunities to leverage knowledge of informal institution and adaptation relationships in targeted formal initiatives. The outcomes of this study contribute to an improved understanding of the function and potential of informal institutions in adaptation processes, the benefits of which extend beyond the local context of Wainwright.

Recent research has focused on the impacts of environmental change to tourism. In particular, the perceived costs of climate change have been increasingly studied. However, the relationship between costs and benefits resulting from the changing environmental conditions for the industry has been less examined. This paper identifies the locally observed changes in the natural and socio-economic environments and aims to analyse the financial costs and benefits to tourism businesses in two tourism-dependent communities in northern Finland. The specific focus is on adaptation and adaptive management in a tourist destination scale. Adaption is understood as an investment creating not only implementation costs, but potentially also benefits for tourism operations. Research materials were collected among tourism and tourism-related businesses through 41 semi-structured thematic interviews. Results indicate that the evaluated benefits of environmental change seem to exceed those of costs. This conforms to the on-going discourse of climate change-tourism relations associated with the Arctic region where both awareness and vulnerability to change are considered relatively high but the level of responses, i.e. adaptation, low. These results can help to further identify the most vulnerable sectors in tourism and assist entrepreneurs preparing for environmental and climate change. However, the paper concludes that while global environmental change, with specific adaptive management strategies, may create local short-term direct benefits for the industry, a long-term sustainability of tourism in the Arctic calls for mitigation responses to climate change.

The paper aimed at estimating the significance of paleoenvironmental changes in the process of the prehistorical human dispersals over Northern Eurasia, and particularly his penetration to the High Latitudes. As follows from the recent investigations, the northeastern part of Europe appears to be settled earlier than it has been supposed until recently. The traces left by the early man in the European Arctic may be dated to 40 000 to 35 000 years BP (43096 to 40159 cal. BP). The Siberian North was colonized in the Late Pleistocene. The materials recovered from the Yanskaya site (71°N) provide evidence of human survival in the Arctic regions of Eastern Siberia at least ca. 28 to 27 ka BP (32780 ± 660 to 31170 ± 520 cal. BP). Valleys in the middle reaches of the Lena and Aldan rivers were populated after 24 000 yr BP (28165 cal. BP). We may identify two main directions in the High Latitude colonization between 40 000 to 12 000 yr BP [43096 to 13907 cal. BP], namely along the basins of the Kama and Pechora rivers in Eastern Europe and by way of the Lena and Yana basins in Northern Asia. West Siberia and the Northeastern Asia were actively populated at the Late Glacial time; the same period was marked by the first human penetration from the Eastern to Western hemisphere (from the Chukchi Peninsula to Alaska) by the 'Bering Land Bridge'. The northernmost regions of the East Siberia, such as Taymyr Peninsula and the New Siberian Islands (Zhokhov Island), were inhabited in the early and middle Holocene. [ABSTRACT FROM AUTHOR]

Scientific evidence gathered over the past five years suggests that northern Canada and the Arctic have undergone, and are undergoing, formidable environmental changes linked to global climate change. Environmental change in the north is expected to persist and intensify over the course of the next century. When large-scale environmental changes take place, they inevitably affect people, especially when the cultures and livelihoods of those people depend on their relationship with the environment. Managing the local impacts of these changes is a matter of adaptation. This paper discusses some of the policy implications of adaptation--government interventions aiming to build communities' and regions' capacities to adapt to environmental changes. Three arguments for adaptive capacity building interventions in the north are discussed, and these arguments are augmented by a comparative review of government reactions to the collapse of the cod fishery in Atlantic Canada. Reactive and proactive policy approaches are discussed, and it is suggested from the comparison that proactive approaches to intervention are desirable for building adaptive capacity.

This paper develops a methodology for climate change adaptation planning in remote, resource-dependent communities. The methods are structured using a vulnerability framework, and community members, local stakeholders and researchers are engaged in an iterative planning process to identify, describe, prioritize and pilot adaptation actions. The methods include: (1) analysis of secondary sources of information, (2) community collaboration and partnership building, (3) adaptation planning workshops, (4) adaptation plan development, (5) key informant and community review and (6) pilot adaptation actions. Vulnerability to climate change is assessed in the context of other non-climatic factors-social, political, economic and environmental, already being experienced in communities and which influence how climate change is experienced and responded to. Key exposure-sensitivities and related adaptation options are identified in five sectors of a community: business and economy, culture and learning, health and well-being, subsistence harvesting, and transportation and infrastructure. This organization allows for focused discussions and the involvement of relevant stakeholders and experts from each sector. The methodology is applied in Paulatuk, an Inuit community located in the Inuvialuit Settlement Region (ISR), Northwest Territories (NWT), Canada, and key findings are highlighted. The methods developed have important lessons for adaptation planning in remote, resource-dependent communities generally and contributes to a small but growing scholarship on methodology in the human dimensions of climate change.

There is limited knowledge on institutional factors constraining and enabling climate change adaptation in Arctic regions, or the overall readiness of governing bodies and communities to develop, implement, and promote adaptation. This paper examines the preparedness of different levels of government to adapt in the Canadian Arctic territory of Nunavut, drawing upon semi-structured interviews with government personnel and organizations involved in adaptation. In the Government of Nunavut, there have been notable developments around adaptation planning and examples of adaptation champions, but readiness for adaptation is challenged by a number of factors including the existence of pressing socio-economic problems, and institutional and governmental barriers. Federally, there is evidence of high-level leadership on adaptation, the creation of adaptation programs, and allocation of funds for adaptation, although the focus has been mostly on researching adaptation options as opposed to supporting actual actions or policy change. The 2016 Pan-Canadian Framework on Clean Growth and Climate Change, and increasing emphasis on climate change federally and in the Government of Nunavut, offer opportunities for advancing adaptation, but concrete steps are needed to ensure readiness is enhanced.

The availability of clean drinking water impacts the quality of life of Arctic populations and is affected by climate change. We provide perceptions based on: (1) a study of the accessibility of the natural surface water to the nomadic and settled Indigenous inhabitants living in rural areas (in settlements and remote camps) in the Arctic zone of Western Siberia during climate change and industrial development; (2) an assessment of the impact of consuming different surface water resources on human health. We include primary data sources from medical examinations and surveys collected in the regions between the rivers of Ob, Nadym, Taz, and Yenisey in 2012, 2014–2019, and 2022 whereas the chemical analysis of the surface waters in the region was based on previous research. A total of 552 local residents from the Arctic zone of Western Siberia participated in the study. We discuss how the availability of high-quality drinking water is limited for them due to climatic and anthropogenic risks, despite the abundant water resources. The consumption of river water is associated with high health risks since it contains heavy metals (Pb, Cd, Mn, Fe), whereas the consumption of lake ice melt water likely affects health because of the low concentrations of beneficial ions.

The global human influence on the climate is growing at an alarming pace. This trend appears doomed to continue. Polar regions are feeling the effects first. This means that if the impacts of climate change serve to motivate effective policies, polar regions could be a good place to look for climate policy innovation. It is within this context that this article considers Arctic climate policy in Russia and Canada. The basic question posed is whether the unique and immediate threat climate change presents in the Arctic is reflected in progressive laws and policies with respect to four key areas: mitigation, adaptation, impacts and vulnerability, and development.

Abstract: Co-management institutional arrangements have an important role in creating conditions for social learning and adaptation in a rapidly changing Arctic environment, although how that works in practice has not been clearly articulated. This paper draws on three co-management cases from the Canadian Arctic to examine the role of knowledge co-production as an institutional trigger or mechanism to enable learning and adapting. Experience with knowledge co-production across the three cases is variable but outcomes illustrate how co-management actors are learning to learn through uncertainty and environmental change, or learning to be adaptive. Policy implications of this analysis are highlighted and include the importance of a long-term commitment to institution building, an enabling policy environment to sustain difficult social processes associated with knowledge co-production, and the value of diverse modes of communication, deliberation and social interaction.

How do arctic youth perceive the resilience of their communities? Many of today's high school students in Arctic Alaska will takeup leadership roles in their communities in the next decade. The social-environmental changes these communities face are disruptive andpose challenges to local governance now and into the future. Arctic Futures Makers (AFM) was a scenarios workshop of 22 Alaska Indigenoushigh school students convened over two days in February 2016 on the resilience of the Northwest Arctic Borough's communities in light ofclimate and development changes. The scope of the scenarios workshop focused on defining factors the students felt were key to the futureof healthy and sustainable communities. The intent was to understand how potential leaders perceived the futures of their communities andtheir own role in the changing dynamics of the Arctic. Three findings are significant to explain how these youth think about themselves andtheir region's future: (1) high school students' results are similar to those of adults in similar workshops but with important differencesrelated to what makes a community 'livable' (2) students were initially reticent to imagine multiple possible futures (3) students' perceptionsof their own communities' resilience changed after the workshop experience.

Background: Polar bears are uniquely adapted to an Arctic existence. Since their relatively recent divergence from their closest living relative, brown bears, less than 500,000 years ago, the species has evolved an array of novel traits suited to its Arctic lifestyle. Previous studies sought to uncover the genomic underpinnings of these unique characteristics, and disclosed the genes showing the strongest signal of positive selection in the polar bear lineage. Here, we survey a comprehensive dataset of 109 polar bear and 33 brown bear genomes to investigate the genomic variants within these top genes present in each species. Specifically, we investigate whether fixed homozygous variants in polar bears derived from selection on standing variation in the ancestral gene pool or on de novo mutation in the polar bear lineage. Results: We find that a large number of sites fixed in polar bears are biallelic in brown bears, suggesting selection on standing variation. Moreover, we uncover sites in which polar bears are fixed for a derived allele while brown bears are fixed for the ancestral allele, which we suggest may be a signal of de novo mutation in the polar bear lineage. Conclusions: Our findings suggest that, among other mechanisms, natural selection acting on changes in genes derived from a combination of variation already in the ancestral gene pool, and from de novo missense mutations in the polar bear lineage, may have enabled the rapid adaptation of polar bears to their new Arctic environment.

A fundamentally new integrated approach to the state activity on the adaptation to changing environmental conditions, namely, the territorial planning of land use is proposed by the example of the Arctic zone of the Russian Federation being the most vulnerable region to climate change. Adaptation measures for natural ecosystems are scientifically grounded for the Arctic region: the prevention of permafrost surface cover disturbances, the minimization of other types of anthropogenic impact and pollution, the maintenance and increase in surface albedo in winter. The examples of development of a dual indicator system are given: for monitoring the implementation of measures and adaptation efficiency (the quantitative markers of climate-caused damage). The analysis of all indicators in the adaptation efficiency monitoring system, as well as the projections of indicators for 5–10 years ahead help to make reasoned management decisions to correct the applied adaptation measures. The practical application of the results includes the use of the developed approaches in the sectoral and regional plans and at the second stage of the National Plan for Adaptation to Climate Change.

Bergmann's rule and Allen's rule played important roles in mid-twentieth century discussions of adaptation, variation, and geographical distribution. Although inherited from the nineteenth-century natural history tradition these rules gained significance during the consolidation of the modern synthesis as evolutionary theorists focused attention on populations as units of evolution. For systematists, the rules provided a compelling rationale for identifying geographical races or subspecies, a function that was also picked up by some physical anthropologists. More generally, the rules provided strong evidence for adaptation by natural selection. Supporters of the rules tacitly, or often explicitly, assumed that the clines described by the rules reflected adaptations for thermoregulation. This assumption was challenged by the physiologists Laurence Irving and Per Scholander based on their arctic research conducted after World War II. Their critique spurred a controversy played out in a series of articles in Evolution, in Ernst Mayr's Animal Species and Evolution, and in the writings of other prominent evolutionary biologists and physical anthropologists. Considering this episode highlights the complexity and ambiguity of important biological concepts such as adaptation, homeostasis, and self-regulation. It also demonstrates how different disciplinary orientations and styles of scientific research influenced evolutionary explanations, and the consequent difficulties of constructing a truly synthetic evolutionary biology in the decades immediately following World War II.

The Arctic region is experiencing transformation due to climate change, generating both threats and opportunities to local communities. In addition to warming, the signs of climate change are expected to materialise through an increase in the frequency and intensity of weather extremes. Climate-change adaptation (CCA) and disaster risk reduction (DRR) have so far operated fairly independently, but there is an emerging need to examine their synergies due to their similarities. Tourism in the Arctic is also increasingly being encouraged by the different levels of government and seen as an important tool for economic development. The special features of Arctic tourism include a high dependency on natural resources, making it vulnerable to the effects of climate change. This article introduces a methodological framework merging elements from DRR, CCA and tourism development with a focus on community-based data-acquiring technique. Its practicality is emphasised through the focus on current and past community responses to weather anomalies and consequent adaptation measures. It additionally explores the relationship between the environment, community and tourism and aims to understand the characteristics of a community. Two case-study communities in Finnish Lapland demonstrate its relevance and contribution to CCA and to wider sustainable Arctic tourism development. [ABSTRACT FROM PUBLISHER]

The dispersal abilities of terrestrial mammals are severely constrained by water crossings, resulting in islands generally supporting less diverse mammal faunas than similar continental areas. In ice-affected Arctic regions, seasonal or permanent ice cover provides a bridging mechanism for dispersal, allowing water gaps to be crossed more rapidly and with less energy cost than is entailed in swimming. Consequently, islands that might be out of reach if waters were open become much more readily colonised in the presence of ice. We reviewed the distribution of terrestrial mammals on selected islands throughout the Arctic and analyse historical data for several sites in the Canadian Arctic where mammal populations have undergone extirpation and re-colonisation. We use these data to assess the value of ice for the dispersal of Arctic terrestrial mammals. Given observed dispersal distances we estimate the likely impact of future ice reduction on island faunas. We predict that, as ice cover duration shortens, immigration will decline leading to increased extinctions of island populations and potentially, in the long-term, local genetic differentiation. The eventual disappearance of ice bridges, preventing the immigration of southern species, may leave certain arctic archipelagos as the last refuge for typical Arctic mammals. [ABSTRACT FROM AUTHOR]

Within three decades, the barnacle goose population wintering on the European mainland has dramatically increased in numbers and extended its breeding range. The expansion has occurred both within the Arctic as well as by the colonization of temperate areas. Studies of performance of individuals in expanding populations provide information on how well species can adapt to novel environments and global warming. We, therefore, studied the availability of high quality food as well as timing of reproduction, wing moult, fledgling production and postfledging survival of individually marked geese in three recently established populations: one Arctic (Barents Sea) and two temperate (Baltic, North Sea). In the Barents Sea population, timing of hatching was synchronized with the peak in food availability and there was strong stabilizing selection. Although birds in the Baltic and North Sea populations bred 6–7 weeks earlier than Arctic birds, timing of hatching was late in relation to the peak in food availability, and there was moderate to strong directional selection for early breeding. In the Baltic, absolute timing of egg laying advanced considerably over the 20-year study period, but advanced little relative to spring phenology, and directional selection on lay date increased over time. Wing moult of adults started only 2–4 weeks earlier in the temperate populations than in the Arctic. Synchronization between fledging of young and end of wing moult decreased in the temperate populations. Arctic-breeding geese may gradually accumulate body stores from the food they encounter during spring migration, which allows them to breed relatively early and their young to use the peak of the Arctic food resources. By contrast, temperate-breeding birds are not able to acquire adequate body stores from local resources early enough, that is before the quality of food for their young starts to decrease. When global temperatures continue to rise, Arctic-breeding barnacle geese might encounter similar problems. [ABSTRACT FROM AUTHOR]
