Tundra ecosystems observed to be CO2 sources due to differential amplification of the carbon cycle
Are tundra ecosystems currently a carbon source or sink? What is the future trajectory of
tundra carbon fluxes in response to climate change? These questions are of global …

Water scaling of ecosystem carbon cycle feedback to climate warming
It has been well established by field experiments that warming stimulates either net
ecosystem carbon uptake or release, leading to negative or positive carbon cycle–climate …

Four degrees and beyond: the potential for a global temperature increase of four degrees and its implications
The 1992 UN Framework Convention on Climate Change commits signatories to preventing
'dangerous anthropogenic interference with the climate system', leaving unspecified the …

Spatial and temporal variation in primary productivity (NDVI) of coastal Alaskan tundra: Decreased vegetation growth following earlier snowmelt
JA Gamon, KF Huemmrich, RS Stone… - Remote sensing of …, 2013 - Elsevier
In the Arctic, earlier snowmelt and longer growing seasons due to warming have been
hypothesized to increase vegetation productivity. Using the Normalized Difference …

Influence of iron redox cycling on organo-mineral associations in Arctic tundra soil
Arctic tundra stores large quantities of soil organic matter under varying redox conditions. As
the climate warms, these carbon reservoirs are susceptible to increased rates of …

[HTML][HTML] Strong legacies of emerging trends in winter precipitation on the carbon-climate feedback from Arctic tundra
Abstract Changes in winter precipitation accompanying emerging climate trends lead to a
major carbon-climate feedback from Arctic tundra. However, the mechanisms driving the …

Arctic greening associated with lengthening growing seasons in Northern Alaska
Many studies have reported that the Arctic is greening; however, we lack an understanding
of the detailed patterns and processes that are leading to this observed greening. The …

Ecosystems disturbance recovery: What it was or what it could have been?
The time it takes for an ecosystem to recover from a disturbance is a key to environmental
management. Conventionally, recovery is defined as a return to the pre‐disturbance state …

Increased wintertime CO2 loss as a result of sustained tundra warming
Permafrost soils currently store approximately 1672 Pg of carbon (C), but as high latitudes
warm, this temperature‐protected C reservoir will become vulnerable to higher rates of …

Increased high‐latitude photosynthetic carbon gain offset by respiration carbon loss during an anomalous warm winter to spring transition
Arctic and boreal ecosystems play an important role in the global carbon (C) budget, and
whether they act as a future net C sink or source depends on climate and environmental …
