  • Affirming Indigenous data sovereignty in collaborative wildlife conservation in the era of open data

    Open AccessErin Tattersall, Warren Cardinal‐McTeague et al.ARTICLEPeople and Nature2025

    In the current data‐driven landscape of wildlife conservation, data sovereignty (i.e. governance and security) is fundamental to determining how knowledge is created and applied to pressing biodiversity concerns. Western science increasingly champions open data, which uplifts data stewardship and sharing to make data more accessible. At the same time, Indigenous Peoples stress the importance of Indigenous data sovereignty (IDS) to assert Indigeno…

  • Snow persistence lowers and delays peak NDVI, the vegetation index that underpins Arctic greening analyses

    Open AccessCalum G Hoad, Isla H Myers‐Smith et al.ARTICLEEnvironmental Research Letters2025

    Satellite imagery is critical for understanding land-surface change in the rapidly warming Arctic. Since the 1980s, studies have found positive trends in the normalised difference vegetation index (NDVI) derived from satellite imagery over the Arctic—commonly referred to as ‘Arctic greening’ and assumed to represent increased vegetation productivity. However, greening analyses use satellite imagery with pixel sizes ranging from tens to hundreds o…

  • Basal ice but not summer temperature affects land surface greenness in parts of the landscape in high Arctic tundra

    Open AccessLia Lechler, Åshild Ønvik Pedersen et al.ARTICLEEnvironmental Research Letters2025

    Climate warming in the Arctic is very strong compared to other regions on Earth. Arctic winter climate and cryosphere conditions are changing towards more frequent mild spells. Precipitation is often falling as rain, followed by the formation of basal ice on frozen ground, particularly in Gulf Stream-influenced climates as in Svalbard. Such conditions encapsulate tundra plants in ice for several months, which is assumed to reduce land surface gre…

  • Borealization of tundra ecosystems with climate and land-use change

    Open AccessMariana Verdonen, Isabel C Barrio et al.ARTICLEEnvironmental Research Letters2025

    As the colder regions of the planet warm, species are moving northward and upward from the boreal forest to the tundra biome, a process that has been referred to as borealization. Here, we examine the diverse uses of the term borealization and propose the concept of ‘tundra borealization’ for terrestrial environments to specifically describe shifts and increases in abundance of boreal species into the tundra. We summarize the evidence to date for…

  • Post-drainage vegetation, microtopography and organic matter in Arctic drained lake basins

    Open AccessJuliane Wolter, Benjamin M Jones et al.ARTICLEEnvironmental Research Letters2024

    Wetlands in Arctic drained lake basins (DLBs) have a high potential for carbon storage in vegetation and peat as well as for elevated greenhouse gas emissions. However, the evolution of vegetation and organic matter is rarely studied in DLBs, making these abundant wetlands especially uncertain elements of the permafrost carbon budget. We surveyed multiple DLB generations in northern Alaska with the goal to assess vegetation, microtopography, and …

  • Range shifts in a foundation sedge potentially induce large Arctic ecosystem carbon losses and gains

    Open AccessSalvatore R Curasi, Ned Fetcher et al.ARTICLEEnvironmental Research Letters2022

    Foundation species have disproportionately large impacts on ecosystem structure and function. As a result, future changes to their distribution may be important determinants of ecosystem carbon (C) cycling in a warmer world. We assessed the role of a foundation tussock sedge ( Eriophorum vaginatum ) as a climatically vulnerable C stock using field data, a machine learning ecological niche model, and an ensemble of terrestrial biosphere models (TB…

  • Growth rings show limited evidence for ungulates’ potential to suppress shrubs across the Arctic

    Open AccessKatariina E M Vuorinen, Gunnar Austrheim et al.ARTICLEEnvironmental Research Letters2022

    Global warming has pronounced effects on tundra vegetation, and rising mean temperatures increase plant growth potential across the Arctic biome. Herbivores may counteract the warming impacts by reducing plant growth, but the strength of this effect may depend on prevailing regional climatic conditions. To study how ungulates interact with temperature to influence growth of tundra shrubs across the Arctic tundra biome, we assembled dendroecologic…

  • Mapping human pressures on biodiversity across the planet uncovers anthropogenic threat complexes

    Open AccessDiana E Bowler, Anne D Bjorkman et al.ARTICLEPeople and Nature2020

    Climate change and other anthropogenic drivers of biodiversity change are unequally distributed across the world. Overlap in the distributions of different drivers have important implications for biodiversity change attribution and the potential for interactive effects. However, the spatial relationships among different drivers and whether they differ between the terrestrial and marine realm has yet to be examined. We compiled global gridded data…

  • Shallow soils are warmer under trees and tall shrubs across Arctic and Boreal ecosystems

    Open AccessHeather Kropp, M M Loranty et al.ARTICLEEnvironmental Research Letters2020

    Soils are warming as air temperatures rise across the Arctic and Boreal region concurrent with the expansion of tall-statured shrubs and trees in the tundra. Changes in vegetation structure and function are expected to alter soil thermal regimes, thereby modifying climate feedbacks related to permafrost thaw and carbon cycling. However, current understanding of vegetation impacts on soil temperature is limited to local or regional scales and lack…

  • Drone data reveal heterogeneity in tundra greenness and phenology not captured by satellites

    Open AccessJakob J Assmann, Isla H Myers‐Smith et al.ARTICLEEnvironmental Research Letters2020

    Data across scales are required to monitor ecosystem responses to rapid warming in the Arctic and to interpret tundra greening trends.Here, we tested the correspondence among satellite-and drone-derived seasonal change in tundra greenness to identify optimal spatial scales for vegetation monitoring on Qikiqtaruk-Herschel Island in the Yukon Territory, Canada.We combined time-series of the Normalised Difference Vegetation Index (NDVI) from multisp…

  • Aboveground biomass corresponds strongly with drone-derived canopy height but weakly with greenness (NDVI) in a shrub tundra landscape

    Open AccessAndrew M Cunliffe, Jakob J Assmann et al.ARTICLEEnvironmental Research Letters2020

    Arctic landscapes are changing rapidly in response to warming, but future predictions are hindered by difficulties in scaling ecological relationships from plots to biomes. Unmanned aerial systems (hereafter ‘drones’) are increasingly used to observe Arctic ecosystems over broader extents than can be measured using ground-based approaches and are facilitating the interpretation of coarse-grained remotely sensed data. However, more information is …

  • Status and trends in Arctic vegetation

    Open AccessAnne D Bjorkman, Mariana García Criado et al.ARTICLEAMBIO2020Citada por: 5Referencias: 102

    Changes in Arctic vegetation can have important implications for trophic interactions and ecosystem functioning leading to climate feedbacks. Plot-based vegetation surveys provide detailed insight into vegetation changes at sites around the Arctic and improve our ability to predict the impacts of environmental change on tundra ecosystems. Here, we review studies of changes in plant community composition and phenology from both long-term monitorin…

  • Contrasting shrub species respond to early summer temperatures leading to correspondence of shrub growth patterns

    Open AccessStef Weijers, Roland Pape et al.ARTICLEEnvironmental Research Letters2018

    The Arctic-alpine biome is warming rapidly, resulting in a gradual replacement of low statured species by taller woody species in many tundra ecosystems. In northwest North America, the remotely sensed normalized difference vegetation index (NDVI), suggests an increase in productivity of the Arctic and alpine tundra and a decrease in productivity of boreal forests. However, the responses of contrasting shrub species growing at the same sites to c…

  • A warmer and greener cold world

    Open AccessStef Weijers, Isla H Myers-Smith et al.ARTICLEErdkunde2018

    The Arctic and alpine biome is rapidly warming, which might be causing an encroachment of relatively tall woody shrub vegetation into tundra ecosystems, which will probably result in an overall positive feedback to climate warming. This encroachment is, however, believed to remain limited to the relatively warm parts of the biome, where taller shrubs may displace shorter species. Still, climate sensitivity of shrub growth strongly differs between…

  • Shrub growth and expansion in the Arctic tundra

    Open AccessAndrew Martin, Elizabeth S Jeffers et al.ARTICLEEnvironmental Research Letters2017

    Woody shrubs have increased in biomass and expanded into new areas throughout the Pan-Arctic tundra biome in recent decades, which has been linked to a biome-wide observed increase in productivity. Experimental, observational, and socio-ecological research suggests that air temperature—and to a lesser degree precipitation—trends have been the predominant drivers of this change. However, a progressive decoupling of these drivers from Arctic vegeta…

  • Recent dynamics of arctic and sub-arctic vegetation

    Open AccessHoward E Epstein, Isla H Myers‐Smith et al.ARTICLEEnvironmental Research Letters2013

    We present a focus issue of Environmental Research Letters on the 'Recent dynamics of arctic and sub-arctic vegetation'. The focus issue includes three perspective articles (Verbyla 2011 Environ. Res. Lett. 6 041003, Williams et al 2011 Environ. Res. Lett. 6 041004, Loranty and Goetz 2012 Environ. Res. Lett. 7 011005) and 22 research articles. The focus issue arose as a result of heightened interest in the response of high-latitude vegetation to …

  • Shrub expansion in tundra ecosystems

    Open AccessIsla H Myers‐Smith, Bruce C Forbes et al.ARTICLEEnvironmental Research Letters2011

    Recent research using repeat photography, long-term ecological monitoring and dendrochronology has documented shrub expansion in arctic, high-latitude and alpine tundra ecosystems. Here, we (1) synthesize these findings, (2) present a conceptual framework that identifies mechanisms and constraints on shrub increase, (3) explore causes, feedbacks and implications of the increased shrub cover in tundra ecosystems, and (4) address potential lines of…
