An 18S V4 rRNA metabarcoding dataset of protist diversity in the Atlantic inflow to the Arctic Ocean, through the year and down to 1000 m depth
Arctic marine protist communities have been understudied due to challenging sampling conditions, in particular during winter and in deep waters. The aim of this study was to improve our knowledge on Arctic protist diversity through the year, in both the epipelagic (< 200 m depth) and mesopelagic zon...
Young People, Wellbeing and Sustainable Arctic Communities
Youth are usually not (yet) decision makers in politics or in business corporations, but the sustainability of Arctic settlements depends on whether or not youth envision such places as offering opportunities for a good future. This is the first multidisciplinary volume presenting original research...
PAN-EURASIAN EXPERIMENT (PEEX) PROGRAM: To OVERVIEW OF THE FIRST 5 YEARS IN OPERATION AND FUTURE Prospects
The Pan-Eurasian Experiment (PEEX) program was initiated as a bottom-up approach by the researchers coming fromFinlandandRussiain October 2012. The PEEX China kick off meeting was held in November 2013. During its five years in operation, the program has established a governance structure and delive...
Development of Education for Indigenous Minorities in Alaska
The history of development and modern forms of functioning of education for indigenous minorities in Alaska reveal trends which appeared in other areas of the Arctic. The systematic activity of education, along with the influence of other state institutions (military, offices), and also the often de...

Partnering for Northern Digital Literacy
Communities in the western Arctic can now connect to high-speed digital infrastructure – a situation that provides both opportunities and challenges for residents of the Northwest Territories (NWT). The completion of the long-anticipated Mackenzie Valley Fibre Link (MVFL) in June 2017 and forthcomin...
The Importance of Indigenous Peoples in Climate Change and Energy Governance
Specialization: Risk and Community Resilience Degree: Master of Science Abstract: Indigenous peoples in northern Canada are already experiencing significant climate change impacts. Young Indigenous people will inherit serious climate effects that threaten their physical and mental health, as well as...
Structure and biogeography of the communities of pico- and nanoeurocaryotes pelagic around the Svalbard archipelago
The Arctic is warming rapidly and there is an urgent need to anticipate the effect this will have on the microbial eukaryotes at the base of the food chain. Arctic Ocean phytoplankton include pico- and nano-eukaryotes (0.45-10 μm cell size), many of these are unique ecotypes found only in the Arctic...
Diversity and dynamics of protist communities in the Canadian High Arctic
The Arctic region is a blend of stark windswept landscapes interwoven with a wide diversity of freshwater ecosystems. Presently confronted by temperature increases well above global average, causing changes in landscape and aquatic properties, the Arctic is a strategic area to study the impact of cl...
The under-ice dynamics of High Arctic lakes : the importance of physicochemical interactions with phytoplankton and bacterial communities in Stuckberry Valley, Ellesmere Island
Even the world’s most northern ecosystems have been affected by climate warming and High Arctic lakes are no exception. Ellesmere Island is at the northernmost limit of Canada, and regime shifts have already been documented in its lakes towards taxa associated with longer growing seasons. It has bee...
Using blood and feathers to investigate large-scale Hg contamination in Arctic seabirds: A review
International audience Mercury (Hg), because of its deleterious effects on wildlife and its high concentrations in polar regions, has been widely studied in the Arctic. This provided important information regarding food web contamination, spatial and temporal trends of Hg in ecosystems or risk asses...
POLAR ISLAM IN POST-SOVIET RUSSIA: THE BIRTH OF A PHENOMENON IN THE CONTEXT OF A “NEW” ETHNO-SOCIAL MOBILITY
Aim. To describe and identify the specifics of one of the most understudied aspects of Russian Arctic research: Muslim development in the regions of the rapidly changing Russian North. Methodology. The work analyzes migration flows, examines the process of formation of Muslim communities in the nort...
Assessment of marine invertebrate biodiversity in Arctic commercial ports through environmental DNA
Arctic biodiversity has long been underestimated and is now facing rapid transformations due to ongoing climate change and other impacts including shipping activities. These changes are placing marine coastal invertebrate communities at greater risk, especially in sensitive areas such as commercial...
Signing for Learning Engagement in Remote Communities: Narratives from North of Sixty/Concevoir to foster active participation in learning in remote communities: stories from The North of the 60th parallel
There are multiple challenges to designing learning experiences for schools in remote communities, including technology and infrastructure limitations, high teacher and administrator turnover, and conflicting interests between local culture and school curricula. In this paper, we offer a brief histo...
Coordination of International Organizations of the North-Arctic Regions: to the Program of the Presidency of the Russian Federation in the Arctic Council
Mechanisms for coordinating the activities of international interstate and macro-regional organizations of the North-Arctic regions, the implementation of which may be directly related to the program of the Russian Federation’s Presidency of the International Arctic Council in 2021-2023, are propose...
Beyond bulk δ15N: Combining a suite of stable isotopic measures improves the resolution of the food webs mediating contaminant signals across space, time and communities
Top predators are used as indicators of contaminant trends across space and time. However, signals are integrated over complex food webs, and variation in diet may confound such signals. Trophic position, assessed by bulk δ15N, is widely used to infer the variation in diet relevant to contamination,...
Capturing a Complexity of Nutritional, Environmental, and Economic Impacts on Selected Health Parameters in the Russian High North
The rapid pace of economic exploration of the Arctic against the backdrop of progressing environmental change put a high priority on improving understanding of health impacts in the northern communities. Deficiencies in the capability to capture the complexity of health-influencing parameters along...
Bacterial production and structure of microbial food network in the Mackenzie River and the Coastal Arctic Ocean
Globally significant quantities of organic carbon are stored in northern permafrost soils, but little is known about how this carbon is processed by microbial communities once it enters rivers and is transported to the coastal Arctic Ocean. As part of the Arctic River-Delta Experiment (ARDEX), we me...
The periglacial origin and its influence on thermokarstic ecosystems in Nunavik: analysis of silicious algae communities
The rapid warming increases the degradation and melting of permafrost in subarctic and arctic regions of northern Canada and accelerates the formation of thermokarst ponds. The structure and dynamics of freshwater ecosystems remain little known and little studied. In the context of ADAPT (Arctic Dev...
CRIMINAL LAW AND CRIMINALISTICS PROBLEMS OF LAW ENFORCEMENT AGENCIES ACTIVITY IN ARCTIC REGION

The physical and chemical limnology of Yukon’s largest lake, Lhù’ààn Mân’ (Kluane Lake), prior to the 2016 ‘A’ą̈y Chù’ diversion
Despite increasing evidence that large northern lakes are rapidly changing due to climate change, descriptive baseline studies of their physicochemical properties are largely lacking, limiting our ability to detect or predict change. This study represents a comprehensive scientific assessment of the...
Mitigation strategies to reverse the rising trend of plastics in Polar Regions
Plastic marine pollution in the Arctic today illustrates the global distribution of plastic waste of all sizes traveling by wind and waves, entering food chains, and presenting challenges to management and mitigation.
