NAU ecosystem scientist’s study finds more frequent droughts may endanger ecosystem resiliency
In a new paper published in Nature, research assistant professor Christopher Schwalm of Northern Arizona University’s Center for Ecosystem Science and Society (Ecoss) shares the results of a study investigating the impact of more frequent droughts on ecosystem resiliency and how this phenomenon could endanger the land carbon sink.

NAU illustrator uses art to translate science
A brand new staff member at Northern Arizona University’s Center for Ecosystem Science and Society, Leshyk’s charge is to use the power of art to help interpret and communicate science produced by the center’s researchers as well as others at the university. It’s a unique opportunity to highlight fascinating science that Read more…
Accurate Passion: Metaphor and Meaning in Scientific Art
Tonight at 6:30 PM, please join us at The Green Room for “Accurate Passion: Metaphor and Meaning in Scientific Art” with Victor Leshyk and Dr. Bruce Hungate. In this image-heavy presentation which shares a multiyear portfolio of his artwork, Scientific Illustrator Victor Leshyk discusses the challenges and goals of modern science communication. Read more…
NASA armada targets thaw in Arctic soil
On a 10-meter-square plot of frozen soil in central Alaska, Ted Schuur is creating a window to the future. Schuur, an ecologist at Northern Arizona University (NAU) in Flagstaff, is intentionally warming this patch of permafrost to see how much of its carbon— now locked in frozen plant matter buried Read more…
Ecology & Genomics offer new approaches to combat antibiotic resistance
Antibiotic-resistant bacteria are widespread and are increasingly associated with human infections. Inappropriate antibiotic use – both in people and in animals raised for food – drives the evolution of multi-drug-resistant pathogens and threatens a post-antibiotic era – one in which minor infections can kill. The majority of antibiotics are actually sold for use in food Read more…

Fire expert Michelle Mack comments on Arctic ecosystems and fire activity
How healthy will Earth’s ecosystems be in 2027, 2067 and beyond? It’s an important question to ask, especially on World Environment Day, June 5. To find answers, scientists affiliated with the National Science Foundation’s (NSF) Long-Term Ecological Research (LTER) network came together this spring at an NSF LTER mini-symposium. “Arctic Read more…
Non-linear CO2 flux response to seven years of experimentally induced permafrost thaw
Permafrost, the “always-frozen” deep soil layers of the Arctic, naturally undergoes freeze-thaw cycles with the passage of the brief Arctic spring and summer, which thaws the uppermost layers and fosters a burst of tundra plant growth and pooling meltwater from thawed soil. For millennia, this cycle has re-frozen the Read more…
