Spatiotemporal patterns of tundra fires: late-Quaternary charcoal records from Alaska [PDF]
Biogeosciences, 2015 Anthropogenic climate change has altered many ecosystem processes in the Arctic tundra and may have resulted in unprecedented fire activity. Evaluating the significance of recent fires requires knowledge from the paleofire record because observational ...

Frequent fires in ancient shrub tundra: implications of paleorecords for arctic environmental change. [PDF]
PLoS ONE, 2008 Understanding feedbacks between terrestrial and atmospheric systems is vital for predicting the consequences of global change, particularly in the rapidly changing Arctic.

Increases in graminoids after three decades of change in the High Arctic
Polar Research, 2023 Climate change portends serious implications for Arctic vegetation. Understanding these effects is likely to be enhanced with long-term observations from permanent plots. I evaluated three decades of change in tundra vegetation from 80 permanent plots on

Implications of spatial distributions of snow mass and melt rate for snow-cover depletion: observations in a subarctic mountain catchment [PDF]
, 2004 Spatial statistics of snow water equivalent (SWE) and melt rate were measured using spatially distributed, sequential ground surveys of depth and density in forested, shrub and alpine tundra environments over several seasons within a 185 km(2) mountain ...

Estimation of subsurface porosities and thermal conductivities of polygonal tundra by coupled inversion of electrical resistivity, temperature, and moisture content data [PDF]
, 2020 Studies indicate greenhouse gas emissions following permafrost thaw will amplify current rates of atmospheric warming, a process referred to as the permafrost carbon feedback.

Woody plant encroachment intensifies under climate change across tundra and savanna biomes
Global Ecology and Biogeography, 2020 Biomes worldwide are shifting under global change. Biomes whose extents are limited by temperature or precipitation, such as the tundra and savanna, may be particularly strongly affected by climate change.
