Pools of old carbon in the soil of boreal forests historically safe from combustion are being released by more frequent and larger wildfires, a team led by researchers at Northern Arizona University announced in Nature this week. As the climate of these forests in the Northwest Territories of Canada becomes warmer and drier and… Read more

NAU researchers join Department of Energy project to study the soil microbiome and its effect on carbon persistence
The Earth’s atmosphere, oceans and biosphere are huge reservoirs of carbon, and all play a critical role in global carbon cycling. Soil is one of the largest carbon pools on the planet, storing more carbon than the atmosphere and biosphere combined, yet scientists aren’t sure what regulates carbon persistence—the amount of carbon that remains in the soil.

Seeing the forest for the trees: NAU scientists analyze snowmelt using latest remote sensing technologies
Snowmelt is a vital source of soil moisture in northern Arizona, but in overly dense forests where tree canopies merge, up to 60 percent of the snow never reaches the ground.
A new grant from The Nature Conservancy is funding a two-year interdisciplinary project in which a team of NAU scientists will study the effects of… Read more
