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

  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…

• Is arctic greening consistent with the ecology of tundra? Lessons from an ecologically informed mass balance model

  Climate change has been implicated in the widespread ‘greening’ of the arctic in recent decades. However, differences in arctic greening patterns among satellite platforms and recent reports of decreased rate of greening or of browning have made attributing arctic greening trends to a warming climate challenging. Here, we compared MODIS greening trends to those predicted by the coupled carbon and nitrogen model (CCaN); a mass balance carbon and n…

• Water track distribution and effects on carbon dioxide flux in an eastern Siberian upland tundra landscape

  Open Access•Salvatore R Curasi, M M Loranty et al.•ARTICLE•Environmental Research Letters•2016

  Shrub expansion in tundra ecosystems may act as a positive feedback to climate warming, the strength of which depends on its spatial extent. Recent studies have shown that shrub expansion is more likely to occur in areas with high soil moisture and nutrient availability, conditions typically found in sub-surface water channels known as water tracks. Water tracks are 5–15 m wide channels of subsurface water drainage in permafrost landscapes and ar…
