In a first-of-its-kind warming experiment, researchers at Northern Arizona University found that microbes growth rate decreased over 15 years of warming. The research, published this week in Global Change Biology, showed that under warmer climate conditions, growth decreased among all types of microbes in the community, and suggested that a loss of soil carbon may be responsible… 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

A tale of two understories: how mosses and climate are shaping the fate of nitrogen in the boreal

Posted by Heather Tate on September 4, 2020

Victor Leshyk illustration for New PhytologistMosses and their microbial partners are important players in fertilizing the boreal forests that make up nearly a third of all Earth’s forests. But climate may be changing mosses’ role in how these forests access nutrients, according to a new study led by the Center for Ecosystem Science and Society (Ecoss) at Northern Arizona… Read more

As ice recedes in Antarctica, new microbial research frontier opens for NAU, Texas Tech team

Posted by Heather Tate on April 1, 2020

Purcell_MarrIcePiedmont-photo-credit-Kelly-McMillanWarming global temperatures are changing life on every continent on Earth, including Antarctica, where more microbes are moving in to territory previously covered by ice. How these microbes respond to warming offers us clues about what future Antarctica will look like and who will thrive there. Microbial ecologist and PhD candidate Alicia Purcell from the Center for… Read more

NAU scientists help chart a path to understand how Arctic vegetation is changing

Posted by Heather Tate on January 31, 2020

Scott Goetz
Professor Scott Goetz and assistant research professor Logan Berner (not pictured) are involved in an effort that brings together remote sensing scientists and field ecologists to provide a better understanding of how vegetation is changing across the Arctic

As Arctic tundra has warmed more than twice as fast as the rest of… Read more
