Assessments of recent tundra change based on repeated vegetation surveys
, 2010 Results from experimental warming studies suggest tundra vegetation will respond rapidly and dramatically to climate warming, and indeed, NDVI data from remote sensing and repeat aerial photography suggest such changes may already be occurring.

The snow and the willows : the ecological responses of the alpine dwarf shrub "Salix herbacea" to climate change [PDF]
, 2014 Current changes in shrub abundance in alpine and arctic tundra ecosystems are primarily driven by warming, changes in snow cover time and shifts in biotic interactions.

Identifying multidisciplinary research gaps across Arctic terrestrial gradients
Environmental Research Letters, 2019 Global warming is driving environmental change in the Arctic. However, our current understanding of this change varies strongly among different environmental disciplines and is limited by the number and distribution of field sampling locations.

Determining Subarctic Peatland Vegetation Using an Unmanned Aerial System (UAS)
Remote Sensing, 2018 Rising global temperatures tied to increases in greenhouse gas emissions are impacting high latitude regions, leading to changes in vegetation composition and feedbacks to climate through increased methane (CH4) emissions.

InSAR Detection and Field Evidence for Thermokarst after a Tundra Wildfire, Using ALOS-PALSAR
Remote Sensing, 2016 Thermokarst is the process of ground subsidence caused by either the thawing of ice-rich permafrost or the melting of massive ground ice. The consequences of permafrost degradation associated with thermokarst for surface ecology, landscape evolution, and

Preliminary landscape mapping and analys of ecological features of the island of Vaigach
RUDN Journal of Ecology and Life Safety, 2013 Selected on the basis of decoding of space pictures and analysis of the published data of natural-territorial complexes provide a first idea of the uniqueness of the landscape of the island of Vaigach. Climate warming will cause first of all the activity

Effects of changing permafrost and snow conditions on tundra wildlife: critical places and times
Arctic Science, 2017 The change of water phase around 0 °C has considerable impacts on wildlife ecology because liquid and solid water strongly differ in their insulating capability, mechanical resistance, and light reflectance.
