Impacts of Stoichiometry Traits on Carbon Accumulation using the E3SM Land Model

Plant stoichiometric flexibility controls the CO2 fertilization effect on ecosystem carbon accumulation.

Arctic Soil Governs Whether Climate Change Drives Losses or Gains in Soil Carbon

Multiple models needed to capture true uncertainty of soil carbon fate in a changing world.

Understanding Vertical and Horizontal Flow in Ice-Wedge Polygons

Novel bromide tracer experiments are used to develop a model of subsurface flow and transport within ice-wedge polygons.

Unfrozen Permafrost Presence in Shrub-Dominated Landscapes

Field observations and model simulations confirm the presence of unfrozen permafrost in shrub-dominated landscapes.

Tundra Plant Trait Database

Worldwide trait database addresses long-standing questions about trait-environment relationships and provides an unprecedented digital resource to inform Earth system models.
