Researcher Andrew Sanchez measuring the trunk of a tree

Research institutes in Arizona, Colorado and New Mexico signed a $16.47-million agreement with the U.S. Forest Service to map forest treatments and measure their effectiveness in reducing the risk of catastrophic wildfires.  

The money is directed from the Infrastructure Investment and Jobs Act passed by… Read more

Ecosystems have a long memory. That may not be a good thing.

What scientists have learned is that extreme climate events like drought and heat waves don’t just negatively impact plants, trees and other vegetation while they’re ongoing. The effects of climate extremes, especially droughts,… Read more

New NAU study measures long-term carbon loss from thawing permafrost in Alaska

Posted by Heather Tate on May 6, 2021

Ted Schuur workin in labNew long-term data from a permafrost monitoring site in Healy, Alaska, suggest it was a net carbon source to the atmosphere at least since 2004 and, under current climate conditions as the region grows warmer, will continue to be one, potentially losing up to a fifth of all carbon stored… Read more

NAU ecologist receives grant to study improvements in pollinator habitat, biodiversity in Arizona utility’s rights-of-way

Posted by Heather Tate on January 6, 2021

Clare Aslan working in pollinator field researchBees, butterflies and other insects are important plant pollinators in natural ecosystems and agricultural settings. However, pollinator populations have been decreasing in recent decades. Researchers say one factor contributing to the decline is the degradation and loss of their habitat. Northern Arizona University ecologist and conservation biologist Clare… Read more

When it comes to global plant production, new study suggests phosphorus matters everywhere

Posted by Heather Tate on March 30, 2020

Challenging long-held assumptions that phosphorus limits aboveground plant growth mainly in tropical regions, a new paper in Nature Communications by NAU authors suggests that this important nutrient actually helps govern plant production in temperate regions, too, and on every continent except Antarctica.


Analyzing data from phosphorus field experiments conducted worldwide between 1955-2017, authors Enqing… Read more
