Thawing Permafrost Increases Old Soil And Autotrophic Respiration In Tundra: Partitioning Ecosystem Respiration Using δ13C And ∆14C
Hicks Pries, C. E., Schuur, E. A., Crummer, K. G.

Ecosystem respiration (Reco) is one of the largest terrestrial carbon (C) fluxes. The effect of climate change on Reco depends on the …

Quantification Of Upland Thermokarst Features With High Resolution Remote Sensing
Belshe, E. F., Schuur, E. A., Grosse, G.

Climate-induced changes to permafrost are altering high latitude landscapes in ways that could increase the vulnerability of the vast soil carbon pools of the region. Permafrost thaw is temporally dynamic and spatially heterogeneous because, in addition to the thickening of the active …

Moisture Drives Surface Decomposition In Thawing Tundra
Hicks Pries, C. E., Schuur, E. A., Vogel, J. G., Natali, S. M.

Permafrost thaw can affect decomposition rates by changing environmental conditions and litter quality. As permafrost thaws, soils warm and thermokarst (ground subsidence) features form, causing some areas to become wetter while other areas become drier. We used a common substrate to measure how permafrost thaw affects decomposition …

Holocene Carbon Stocks And Carbon Accumulation Rates Altered In Soils Undergoing Permafrost Thaw
Pries, C. E. H., Schuur, E. A., Crummer, K. G.

Permafrost soils are a significant global store of carbon (C) with the potential to become a large C source to the atmosphere. Climate change is causing permafrost to thaw, which can affect primary production and decomposition, therefore affecting ecosystem …

Seven-Year Trends Of CO2 Exchange In A Tundra Ecosystem Affected By Long-Term Permafrost Thaw
Trucco, C., Schuur, E. A., Natali, S. M., Belshe, E. F., Bracho, R., Vogel, J.

Arctic warming has led to permafrost degradation and ground subsidence, created as a result of ground ice melting. Frozen soil organic matter that thaws can increase carbon (C) emissions to the atmosphere, but this can be offset in part by increases in plant growth. The balance of plant and microbial processes, and how this balance …

Incorporating Spatial Heterogeneity Created By Permafrost Thaw Into A Landscape Carbon Estimate
Belshe, E. F., Schuur, E. A., Bolker, B. M., Bracho, R.

The future carbon balance of high-latitude ecosystems is dependent on the sensitivity of biological processes (photosynthesis and respiration) to the physical changes occurring with permafrost thaw. Predicting C exchange in these ecosystems is difficult because the thawing of permafrost is a heterogeneous process that creates a complex …

Soil CO2 Production In Upland Tundra Where Permafrost Is Thawing
Lee, H., Schuur, E. A. G., Vogel, J. G.

Permafrost soils store nearly half of global soil carbon (C), and therefore permafrost thawing could lead to large amounts of greenhouse gas emissions via decomposition of soil organic matter. When ice-rich permafrost thaws, it creates a localized surface subsidence called thermokarst terrain, which changes the soil microenvironment. …

The Effect Of Permafrost Thaw On Old Carbon Release And Net Carbon Exchange From Tundra
Schuur, E. A., Vogel, J. G., Crummer, K. G., Lee, H., Sickman, J. O., Osterkamp, T. E.

Permafrost soils in boreal and Arctic ecosystems store almost twice as much carbon1, 2 as is currently present in the atmosphere

Response Of CO2 Exchange In A Tussock Tundra Ecosystem To Permafrost Thaw And Thermokarst Development
Vogel, J., Schuur, E. A. G., Trucco, C., Lee, H.

Climate change in high latitudes can lead to permafrost thaw, which in ice-rich soils can result in ground subsidence, or thermokarst. In interior Alaska, we examined seasonal and annual ecosystem CO2exchange using static and automatic chamber measurements in three areas of a moist acidic tundra ecosystem undergoing varying …

Plant Species Composition And Productivity Following Permafrost Thaw And Thermokarst In Alaskan Tundra
Schuur, E. A., Crummer, K. G., Vogel, J. G., Mack, M. C.

Climate warming is expected to have a large impact on plant species composition and productivity in northern latitude ecosystems. Warming can affect vegetation communities directly through temperature effects on plant growth and indirectly through alteration of soil nutrient availability. In addition, warming can cause permafrost …
