This paper explores cultural narratives and oral histories related to two examples of traditional northern transport—long seal hunting journeys in the Baltic region and nomadic reindeer travel in northeastern Siberia. Ample material has been collected and reviewed regarding means of nonmotorised transport in the polar regions. However, scientific literature concerning the experiences and perspectives of the Indigenous and traditional community members who took part in these journeys remains scarce. This article explores the recorded narratives of two people involved in the journeys described. It assesses how these long-distance travels form significance, meaning, observations, and belonging to landscapes for these people. This analysis reveals that, rather than inhabiting northern ice and tundra scapes that are often described as barren and devoid of life, seal hunters and reindeer herders live in story-scapes rich in meaning. The sacred places, surrender to ice flow dynamics, and ways of living “inside” northern habitats that emerge from these testimonies offer a skeleton key for re-reading the misunderstood homelands of Arctic and tundra communities.

The Cape Bounty Arctic Watershed Observatory (CBAWO), Melville Island, Nunavut (74°55′N, 109°34′W) was established in 2003 to examine Arctic ecosystem processes that would be impacted by climate warming and permafrost degradation. This paper provides a synthesis of how remote sensing has contributed to biogeophysical modelling and monitoring at the CBAWO from 2003 to 2023. Given the location and isolated nature of the CBAWO in the Canadian High Arctic, remote sensing data and derivatives have been instrumental for studies examining ecosystem structure and function at local and landscape scales. In combination with field measurements, remote sensing data facilitated mapping and modelling of vegetation types, % vegetation cover and aboveground phytomass, soil moisture, carbon exchange rates, and permafrost degradation and disturbance. It has been demonstrated that even in an environment with limited vegetation cover and phytomass, spectral vegetation indices (e.g., the normalized difference vegetation index) are able to model various biogeophysical variables. These applications are feasible for research sites such as the CBAWO using high spatial resolution remote sensing data across the visible, infrared, and microwave regions of the electromagnetic spectrum. Furthermore, as the satellite record continues to expand, we will gain a greater understanding of the impacts arising from the expected continued warming at northern latitudes. Although the logistics for research in the Arctic remain challenging, today's technologies (e.g., high spatial resolution satellite remote sensing, automated in situ sensors and data loggers, and wireless communication systems) can support a host of scientific endeavours in the Arctic (and other remote sites) through modelling and monitoring of biogeophysical variables and Earth surface processes with limited but critical field campaigns. The research synthesized here for the CBAWO highlights the essential role of remote sensing of terrestrial ecosystems in the Canadian Arctic.

This Indigenous-led project aims to better understand historical and contemporary ways in which Alaska Native Peoples steward salmon and the values connected to salmon stewardship. Indigenous Peoples have stewarded Alaska lands and waters for thousands of years yet have been largely excluded from western science and management systems. In this project, we utilize a participatory approach that allows for the equitable valuing of ideas and knowledges to document the breadth and depth of Yup'ik and Athabascan knowledge and governance systems in southwestern Alaska. We reshape research methodologies by centering Indigenous frameworks and methodologies, including circle dialogues and multi-generational interviews led by Indigenous scholars and students in their home communities and regions. In this paper, we share the Yup'ik and Athabascan values, knowledge, management, and governance mechanisms that can improve the long-term sustainability and equity of Alaska salmon systems. This research elevates the voices of Alaska Native salmon stewards and experts from the Kuskokwim Bay and the Kuskokwim River. We elaborate on five key themes that emerged from this research, including traditional Indigenous ways of life, Indigenous stewardship, self-determination, food and livelihood sovereignty, and ecosystem changes, and identify a more equitable and sustainable path forward for salmon and people in Alaska.

The roles of Indigenous youth in environmental research remain largely unexplored with little practical guidance for achieving meaningful engagement in environmental research. This paper aims to characterize the varying types of Inuit youth engagement in environmental research conducted in Inuit Nunangat. Findings were derived from a community-engaged participatory research approach in Mittimatalik (Pond Inlet, Nunavut). Our typology of Inuit youth engagement in environmental research suggests three types of engagements: “participate”, “conduct”, and “control”. Results highlight that Inuit youth who are interested in undertaking their own environmental research projects expect to enhance their knowledge of natural and life sciences more than those who may seek short-term supportive research roles. Strategies employed by researchers seeking to enhance youth research capacity may also vary based on youth wants and expectations. Our findings suggest that there is no one-size-fits all solution. None of the engagement types identified were necessarily and inherently considered better than the others by project contributors, unlike what has been proposed in other, hierarchical, typologies. Our proposed typology contributes to a better understanding of the varying roles that Inuit youth can play in environmental research, as well as inform potential frameworks for enhancing Inuit youth engagement and leadership in research.

The article presents the discussion on challenging the adverse impacts of climate change taking into consideration both mitigation and adaptation strategies. Topics include improving the livelihood of inhabitants in mountain regions by sustainably increasing ecosystem services; and focusing on the most efficient and cost-effective mitigation options and capitalizing on adaptation–mitigation synergies.

As climate change intensifies, Inuvialuit in Canada's Western Arctic are facing a rapidly changing environment and associated impacts on human health, safety, and food security. Learning to cope with these changes requires context-based and current information that can inform subsistence activities and environmental management, and no one is better positioned to acquire this information than Inuvialuit themselves. This paper presents findings from in-depth interviews conducted in 2012 with six knowledge holders and seasonal residents of Kendall Island (Ukiivik in Uummarmiutun), a traditional whaling camp situated along the Beaufort Sea coast bordering the Okeevik Tarium Niryutait Marine Protected Area. A transdisciplinary and Inuvialuit-led effort, this research documents observations of change at this culturally important site and explores how residents are adapting to changing conditions. Interview transcripts were analyzed using iterative rounds of qualitative coding in NVivo software. Findings reveal pervasive social and environmental change on Kendall Island and in adjacent harvesting areas and highlight how changing conditions are affecting residents’ lives. This study identifies benchmarks upon which to compare and evaluate subsequent changes at this site and documents Inuvialuit knowledge and perspectives that can inform local-scale environmental monitoring, management, and climate change adaptation planning.

Indigenous-driven and community-partnered research projects seeking to develop salient, legitimate, and credible knowledge bases for environmental decision-making require a multiple knowledge systems approach. When involving partners in addition to communities, diverging perspectives and priorities may arise, making the pathways to engaging in principled research while generating actionable knowledge unclear to disciplinarily-trained natural science researchers. Here, we share insights from the Eeyou Coastal Habitat Comprehensive Research Project (CHCRP), an interdisciplinary, Cree-driven community-academic partnership. This project brought together Cree community members, regional organizations, industry (Hydro-Québec), and academics from seven universities across Canada to address the unprecedented loss of seagrass Zostera marina (eelgrass), the concurrent decline in migratory Canada geese and its impact on fall goose harvest activities in Eeyou Istchee. After describing the history and context of the project, we discuss the challenges, complexities, and benefits of the collaborative approach balancing saliency, legitimacy and credibility of the knowledge produced. We suggest the paper may be of use to researchers and partners seeking to engage in principled and actionable research related to environmental change including impacts of past development.

A scenario-based approach was used to test air and ground response to warming with and without changes to inverted surface lapse rates in four Yukon valleys. Generally, climate warming coupled with weakening of temperature inversions resulted in the greatest increase in air temperature at low elevations. However, ground temperatures at high elevations showed the greatest response to warming and variability between scenarios due to increased connectivity between air and ground. Low elevations showed less of a response to warming and permafrost was largely preserved in these locations. Local models also predicted higher permafrost occurrence compared to a regional permafrost probability model, due to the inclusion of differential surface and thermal offsets. Results show that the spatial warming patterns in these mountains may not follow those predicted in other mountain environments following elevation dependent warming (EDW). As a result, the concept of EDW should be expanded to become more inclusive of a wider range of possible spatial warming distributions. The purpose of this paper is not to provide exact estimations of warming, but rather to provide hypothetical spatial warming patterns, based on logical predictions of changes to temperature inversion strength, which may not directly follow the distribution projected through EDW.

This paper presents the first repeat study of glacier foreland chronosequences conducted in the Canadian High Arctic. Vascular plant species at three forelands on Ellesmere Island, Nunavut first surveyed in 1995 were resurveyed 21 years later to (1) test the original hypothesis that succession on these forelands was directional, and (2) investigate the use of the chronosequence method in High Arctic succession studies. Forelands were surveyed using percent cover estimates or presence/absence counts. Indicator species analysis and rates of change were used to quantify shifts. Total plant cover and species richness increased on younger terrain. Rates of peak cover and first appearance advance varied greatly between species and forelands, but were generally faster for graminoid and forb species than shrub species. We observed a pattern of directional succession at all three forelands, supporting the original hypothesis. However, species-specific patterns and rates of change acted to create assemblages that differed between 1995 and 2016, different successional trajectories were observed between the three forelands, and the first occurrence of most species was further from the glacier margin in 2016 compared to 1995. These results demonstrate the importance of repeat studies over time and replication over space to confirm observations in chronosequence studies.

This paper documents the first comprehensive inventory of thermokarst and thaw-sensitive terrain indicators for a 2 million km2 region of northwestern Canada. This is accomplished through the Thermokarst Mapping Collective (TMC), a research collaborative to systematically inventory indicators of permafrost thaw sensitivity by mapping and aerial assessments across the Northwest Territories (NT), Canada. The increase in NT-based permafrost capacity has fostered science leadership and collaboration with government, academic, and community researchers to enable project implementation. Ongoing communications and outreach have informed study design and strengthened Indigenous and stakeholder relationships. Documentation of theme-based methods supported mapper training, and flexible data infrastructure facilitated progress by Canada-wide researchers throughout the COVID-19 pandemic. The TMC inventory of thermokarst and thaw-sensitive landforms agree well with fine-scale empirical mapping (69%–84% accuracy) and aerial inventory (74%–96% accuracy) datasets. National- and circumpolar-scale modelling of sensitive permafrost terrain contrasts significantly with TMC outputs, highlighting their limitations and the value of empirically based mapping approaches. We demonstrate that the multiparameter TMC outputs support a holistic understanding and refined depictions of permafrost terrain sensitivity, provide novel opportunities for regional syntheses, and inform future modelling approaches, which are urgently required to comprehend better what permafrost thaw means for Canada's North.

This study is a meta-analysis of recent global research articles on hydrogeochemical modelling of permafrost regions to determine trends and consensus on research gaps and future research directions. The hydrogeochemical response of permafrost to climate change remains challenging to estimate and forecast despite evidence of large-scale impacts on freshwater and ecological cycles. We investigate the feasibility, need, and potential for hydrogeochemical modelling of permafrost landscapes by reviewing recommendations from previous modelling, review, and primer papers, including discussing ways to advance this type of modelling science. Key permafrost hydrogeochemical processes are discussed, including heat transfer and associated freeze–thaw regimes, biogeochemical processes and rates, and surface and subsurface flow. Modelling considerations (i.e., model dimension, scale, heterogeneity, and permafrost zonation) and model parameters are subsequently examined. Finally, limitations and additional considerations for advancing permafrost hydrogeochemical modelling efforts are reviewed. The findings of this review are summarized in recommendations, tables, and two schematics incorporating key considerations for future hydrogeochemical modelling initiatives in permafrost environments.

Historical film and media collections in the North contain an essential, indelible message for the future — that cultural knowledge is perishable and impermanent. Throughout the world as bearers of traditional culture pass away, much of their knowledge is lost. Film and audio collections can play a critical role in preserving living knowledge, allowing us to observe, experience, and study singular, irreproducible moments of a culture’s past. As time passes, these unique recorded moments take on a vital function; they become new conduits of knowledge, a visual and aural stand-in for real experience. This paper discusses the role of museum film and audio collections in preserving cultural knowledge and the challenges of extending this resource to the classrooms of remote communities throughout the North. The paper also discusses the collaborative cultural filmmaking initiative of Sarah Elder and Leonard Kamerling, their work with partner Alaska Native communities over a period of two decades, and their setbacks and successes in producing “authentic” records of Alaska Native life in the 1970s and 1980s, records that are now part of the Alaska Documentary Collections at the University of Alaska Museum of the North.

Open top chambers (OTCs) were adopted as the recommended warming mechanism by the International Tundra Experiment network in the early 1990s. Since then, OTCs have been deployed across the globe. Hundreds of papers have reported the impacts of OTCs on the abiotic environment and the biota. Here, we review the impacts of the OTC on the physical environment, with comments on the appropriateness of using OTCs to characterize the response of biota to warming. The purpose of this review is to guide readers to previously published work and to provide recommendations for continued use of OTCs to understand the implications of warming on low stature ecosystems. In short, the OTC is a useful tool to experimentally manipulate temperature; however, the characteristics and magnitude of warming varies greatly in different environments; therefore, it is important to document chamber performance to maximize the interpretation of biotic response. When coupled with long-term monitoring, warming experiments are a valuable means to understand the impacts of climate change on natural ecosystems.

The paper is aimed at assessing the associations between the road networks geography and dynamics of wildfire events in the East Siberian boreal forest. We examined the relationship between the function of roads, their use, and management and the wildfire ignition, propagation, and termination during the catastrophic fire season of 2016 in the Irkutsk Region of Russia. Document analysis and interviews were utilized to identify main forest users and road infrastructure functional types and examine wildfire management practices. We combined community observations and satellite remotely sensed data to assess relationships between the location, extent, and timing of wildfires and different types of roads as fire sources, barriers, and suppression access points. Our study confirms a strong spatial relationship between the wildfire ignition points and roads differentiated by their types with the highest probability of fire ignition near forestry roads and the lowest near subsistence roads. Roads also play an important role in wildfire suppression, working as both physical barriers and access points for firefighters. Our research illustrates the importance of local and Indigenous observations along the roads for monitoring and understanding wildfires, including “zombie fires”. It also has practical implications for fire management collectively developed by authorities and local communities.

Soils, next to vegetation, are one of the most popular indicators in environmental quality studies. The response of soil to air pollution is less complex than the response of vegetation. In soils, mainly in their upper layers, the deposition of compounds may occur almost undisturbed; therefore, results of chemical analyses are readily used in the assessment of changes caused by natural processes and anthropogenic activities. In a temperate climate zone, the outermost layer of forest soils is formed by an organic horizon (O), which comprises two basic subhorizons, of which the organic fermentative-humic subhorizon (Ofh) is recognized as the most noteworthy. The subhorizon Ofh encompasses partially and fully decomposed organic matter (humic and fulvic acids, humins), as well as Fe, Mn, and Al oxides and hydroxides, forming a characteristic tangled mat. The structure pattern of this subhorizon is responsible for the higher concentrations of elements and organic compounds, which are immobilized through sorption, complexation, or precipitation. Some previous studies have shown that the subhorizon Ofh has enhanced accumulative properties in comparison to the remaining subjacent soil horizons. Results derived from soil studies in the Holy Cross Mountains (south-central Poland) have also revealed that this subhorizon is mainly enriched in polycyclic aromatic compounds (polycyclic aromatic hydrocarbons) and some trace elements (Hg, Cd, Cu, Pb, and Zn). This could make the subhorizon Ofh a potential geoindicator of soil quality in relation to these compounds over the temperate climate zone. However, further study on this issue is needed to confirm its application in environmental monitoring. [ABSTRACT FROM AUTHOR]

The only available theoretical model explaining the natural development of lakes is a set of assumptions underlying the so-called lake aging concept (LAC). It incorrectly states that with time, lakes age and are inevitably and unidirectionally subject to eutrophication processes. In its most radical version, it misidentifies eutrophication, i.e., an increase in productivity resulting from enrichment in nutrients, with progressive disappearance of lakes over geological timescales due to the filling of the basin with sediment. To this day, LAC assumptions are referred to in various sources, including scientific articles, the Internet, official government documents, as well as teaching materials, all despite a critical approach to this concept presented in several publications, including limnology textbooks. This article, for the first time, presents the history of creation of LAC and an analysis of its main assumptions. A new alternative approach to explain lake ontogeny is also proposed, based on the current knowledge from several environmental sciences, including limnology, physical geography, and paleoecology.

Equilibrium modelling, also known as spin-up, is a technique for initializing a stable thermal regime in ground temperature models for permafrost regions. The results act as a baseline for subsequent transient analyses of ground temperature response to climate change or infrastructure. In practice, spin-up procedures are often loosely described or neglected, and the criteria by which a stable thermal regime is evaluated are rarely defined or presented explicitly. In this paper, model results show that no single criterion based on thresholds of inter-cycle temperature change can be used to identify a stable thermal regime in all spin-up scenarios. Results from simulations using a wide range of initialization temperatures and conditions show the number of spin-up cycles can range between 10 and 10 000, and a spin-up criterion as fine as 0.00001 °C/cycle is required to achieve a stable thermal regime suitable for deeper warm permafrost models. The implications of selected threshold criteria are examined in follow-up transient analyses and show that warm permafrost models can be highly sensitive to initial temperature profiles based on the criterion used. The results alert scientists and engineers to the importance of initialization on site-specific and regional permafrost models for transient ground temperature analyses.

The land is where Inuit knowledge transfer has taken place for generations. Land-based programs for learning and healing have been increasingly initiated across Inuit Nunangat in support of Inuit knowledge transfer that was disrupted by colonial settlement policies and imposed governance systems. We worked with Elders in Uqšuqtuuq (Gjoa Haven, Nunavut) to develop a project to understand the connections between caribou and community well-being. They emphasized that Elder–youth land camps are the most effective means for Elders to share their knowledge, for youth to learn, and for researchers to engage in respectful research. We used the Qaggiq Model for Inuktut knowledge renewal as a guiding framework, and we followed the direction of a land camp planning committee to plan, facilitate, and follow-up on three land camps (2011–2013). The Qaggiq Model also outlines the Qaggiq Dialogue as a way of engaging in relational accountability according to Inuit context and values. In this paper, we reflect on the complexities of upholding relational accountability in cross-cultural research — as part of entering into a Qaggiq Dialogue — with particular emphasis on local leadership, ethics and safety, experiential learning, and continuity. Our intention is to help others evaluate the opportunities and limitations of land camps for their own community context and research questions.Inuit tama’nganituqaq ilihaivalau’mata nunamii’lutik.

Efforts to date have not advanced Indigenous participation, capacity building and knowledge in Arctic environmental science in Canada because Arctic environmental science has yet to acknowledge, or truly practice decolonizing research. The expanding literature on decolonizing and Indigenous research provides guidance towards these alternative research approaches, but less has been written about how you do this in practice and the potential role for non-Indigenous research partners in supporting Inuit self-determination in research. This paper describes the decolonizing methodology of a non-Indigenous researcher partner and presents a co-developed approach, called the Sikumiut model, for Inuit and non-Indigenous researchers interested in supporting Inuit self-determination. In this model the roles of Inuit and non-Indigenous research partners were redefined, with Inuit governing the research and non-Indigenous research partners training and mentoring Inuit youth to conduct the research themselves. The Sikumiut model shows how having Inuit in decision-making positions ensured Inuit data ownership, accessibility, and control over how their Inuit Qaujimajatuqangit is documented, communicated, and respected for its own scientific merit. It examines the benefits and potential to build on the existing research capacity of Inuit youth and describes the guidance and lessons learned from a non-Indigenous researcher in supporting Inuit self-determination in research.

Subsistence is the basis for food access for Inuvialuit in the western Canadian Arctic and has strong economic, dietary, and cultural importance. Inuvialuit harvest beluga whale (Delphinapterus leucas (Pallas, 1776)) from the eastern Beaufort beluga population during summer months within parameters established through co-management. Over the past thirty years there has been a dramatic decline in the number of beluga harvested by Inuvialuit from the community of Aklavik, Northwest Territories. This paper investigates the potential drivers of change, both social and ecological, affecting the beluga harvest. Data were collected using 32 semi-directed interviews and experiential learning. Results revealed that ecological changes, notably coastal erosion at preferred whaling camps and unpredictable and severe weather have made harvesting more difficult, expensive, and often impractical. These changes are being experienced together with social changes including the loss of elders and their knowledge, and changing values and motivations for harvesting beluga. We conclude that no one driver is responsible for the decline in the beluga harvest, but rather it is the result of multiple social-ecological changes operating across scales that affect the feasibility of the harvest and motivation to participate.

Inuit hunters and meteorologists alike pay close attention to weather and weather changes, with deep understandings. This paper describes a long-time research project based in Kangiqtugaapik (Clyde River), Nunavut, where a research team of Inuit and visiting scientists have combined information and knowledge from a community-based weather station network, on-going interviews and discussions, and extensive travel (both Arctic fieldwork and visits to southern universities) to co-produce knowledge related to human–weather relationships and weather information needs and uses in one Nunavut community. The project uses the concept of “HREVs”, human-relevant environmental variables — complex, synthesis variables that, used in conjunction with a host of social variables, assist in informing safe land travel and activities. This work, including linking Inuit knowledge and environmental modeling, can be expanded to not only understand human–weather relationships more broadly and in other locations but also provide insights into the process of building diverse research teams and knowledge co-production.

Researchers wishing to conduct studies in Nunavut are asked by potential funders and licensing agencies to incorporate Inuit Qaujimajatuqangit (IQ) and meaningfully engage Inuit communities, but they must usually interpret for themselves what this means and how to do it in practice. As a group of Inuit youth from four Nunavut communities, we have developed a concept we call ScIQ (pronounced sigh-cue) to describe how science and IQ can be combined for more meaningful engagement to benefit both Inuit communities and scientific researchers. ScIQ is based on the understanding that IQ is not only knowledge that Inuit have gained over many generations; it is more holistic and includes Inuit values, customs and principles for living our lives. Incorporating IQ into research then, should be as much about how research is conducted as it is about data collected from Inuit and local knowledge used to conduct the research. Over a five-day Ikaarvik Youth ScIQ Summit in Cambridge Bay, Nunavut, we developed 45 recommendations for specific things researchers can do before, during, and after their research that, from our perspective, are examples of truly incorporating IQ and result in more meaningful engagement of Inuit communities. This paper presents the Ikaarvik ScIQ recommendations.

This communication paper reflects on discussions from a workshop about Indigenous involvement in the peer review and editorial processes. Arctic-based research is undergoing a paradigm shift to include local Indigenous Peoples, their priorities, and knowledge throughout the research process. This special issue is an excellent example; it highlights research involving partnerships between Indigenous and non-Indigenous researchers to support knowledge co-production. Despite this shift, we find little space within the standard peer review and editorial processes for Indigenous Peoples, their perspectives, and knowledge. To discuss this issue, we organized a half-day workshop at the 2019 ArcticNet Annual Scientific Meeting with a diversity of Indigenous and non-Indigenous participants who are involved in Arctic research. The discussions revealed that answering questions about the involvement of Indigenous Peoples in the peer review and editorial processes largely begins by addressing the challenges of achieving equity in the research process generally. Our discussions demonstrated that further conversations are needed and that no single approach will work in all cases, but that there are several concrete actions that researchers, universities, funding organizations, and publishers can take to begin addressing this issue.

The article focuses on geothermal energy is considered one of the most promising sources of renewable and clean energy, it may not be as benign as widely believed. Topics include the environmental challenges for geothermal resource extraction and describe potential reclamation strategies for disturbed ecosystems, and the environmental impacts of geothermal power generation and direct use are minor and in most cases controllable.

The article focuses on greenhouse gas emissions from peatlands under manipulated warming, nitrogen addition, and vegetation composition change. Topics include the carbon dioxide in the atmosphere has absorbed by the vegetation through photosynthesis, the decomposition is another essential factor in carbon accumulation, and the waterlogged peat and low temperature are two limiting factors for the decomposition.

This paper documents Inuvialuit traditional ecological knowledge of beluga, including ecology and behavior, hunting techniques, and food preparation under changing climatic conditions in Tuktoyaktuk, NT. Beluga whale (Delphinapterus leucas) is an important food source for Inuvialuit in the western Canadian Arctic, a region that is experiencing dramatic climate change. Data were collected using semi-directed interviews with 17 Inuvialuit beluga harvesters and participant observation. The research found that Inuvialuit beluga harvesters possess detailed rational knowledge of beluga, particularly regarding hunting techniques and food preparation, both which are guided by a moral code about how to behave with respect to beluga. In terms of beluga ecology and behavior, Inuvialuit knowledge is limited to anecdotal reasoning drawing on generalized observations of beluga and the accounts of others. Inuvialuit are experiencing the effects of climate change, but seem to be coping thus far in the context of beluga harvesting but ongoing change in the region may increase the risks associated with hunting and preparing beluga in the future.

This paper reports on interviews conducted during June and July 2015 to document ecological knowledge of beluga whales (Delphinapterus leucas) in Ulukhaktok, Northwest Territories. Beluga whales are not a traditionally available or important species for Ulukhaktomiut, but they have appeared in increasing numbers in the waters around the community, and hunters have actively pursued and taken them. We conducted interviews in English with 31 Inuit about their beluga knowledge. A Key Words in Context (KWIC) analysis of the word “know” in the narratives reveals different conceptions of what it means to know something about whales. “Know” variously references practical skill, concern and empathy for others, or the developing awareness of one’s place in the world. Each of these meanings is coded uniquely in Inuinnaqtun, providing insights about the important differences between researchers and Inuit in how “ecological knowledge” is understood and activated.

The article discusses a study that investigated the use of coal fly ash (CFA) as a new support for a reagent for organic synthesis. Highlights include thiol-bromide coupling for the synthesis of cyclophanes with equivalent aromatic units, examples of CFA-supported metal catalysts for use in organic synthesis, and removal of solvents under reduced pressure using a rotary evaporator.

By the establishment of the Greenland Botanical Survey in 1962 at the Botanical Museum, University of Copenhagen, an era of regular and systematic exploration of the vascular plant flora of Greenland was initiated and it ended in 1996, when funding ended. Preceding this period, the vascular plant flora was mainly known from the results of more sporadic botanical investigations mostly in low arctic West and East Greenland, but after the 1980s, investigations expanded to include the more inaccessible high arctic Northeast and North Greenland. Nowadays, vascular plant species have been collected from most regions of Greenland. So far, three regional phytogeographical studies of South, North, and West Greenland have been published, and at present, two papers dealing with the vascular plant flora of East Greenland are ready for publication. These studies will be the basis for a synopsis of the phytogeography of Greenland and a new edition of the Flora of Greenland. The published distribution maps from South, West, and North Greenland based on these collections have been digitized and used for modelling the regional vegetation and flora and its relation to past glaciations and current climate. The specimens from East Greenland have been entered into a database and will be available for future modelling projects.

If the current rate of climate change continues, the composition, distribution, and relative population sizes of species in the higher latitudes of the Northern Hemisphere are likely to change considerably. Understanding the magnitude of this change requires a well- documented baseline against which to compare. Although specimen-less observations can help augment such a baseline for the minority of organisms that can be confidently identified in the field or from photographs, the vast majority of species are small-bodied invertebrates, primarily arthropods, that can only be identified from preserved specimens and (or) their tissues. Museum staff archive specimens and make them and their data available for research. This paper describes a number of challenges to the goal of thorough documentation of high-latitude arthropod biodiversity and their potential solutions. Examples are provided from ongoing and recently completed research that demonstrates the value of museum specimens and the sharing of their data via global portals like GBIF.org.
