▪ Abstract The Arctic is a key part of the global climate system because the net positive
energy input to the tropics must ultimately be resolved through substantial energy losses in …

Whether the fraction of total forest biomass distributed in roots, stems, or leaves varies
systematically across geographic gradients remains unknown despite its importance for …

Soils in equilibrium with a natural forest ecosystem have high carbon (C) density. The ratio
of soil: vegetation C density increases with latitude. Land use change, particularly …

The scientific community, forest managers, environmental organizations, carbon-offset
trading systems and policy-makers require tools to account for forest carbon stocks and …

Fire is a common disturbance in the North American boreal forest that influences ecosystem
structure and function. The temporal and spatial dynamics of fire are likely to be altered as …

We have developed a dynamic land model (LM3V) able to simulate ecosystem dynamics
and exchanges of water, energy, and CO2 between land and atmosphere. LM3V is …

In nature, forest vegetation and soil have evolved as coupled ecosystems over a long period
of time by natural succession in a place. Some abandoned croplands have also been …

In terrestrial high‐latitude regions, observations indicate recent changes in snow cover,
permafrost, and soil freeze–thaw transitions due to climate change. These modifications may …

Growing season CH4 fluxes were monitored over a two year period following the start of
ecosystem‐scale manipulations of water table position and surface soil temperatures in a …

Studies indicate that, historically, terrestrial ecosystems of the northern high‐latitude region
may have been responsible for up to 60% of the global net land‐based sink for atmospheric …
