Congratulations to Lissy Enright (MS, Biology) for winning 3rd place overall at the 3 Minute Research Presentation Southwest regionals this past weekend at the University of Nevada, Reno! Lissy advanced to the regionals by taking 3rd and Best Slide (in collaboration with Victor Leshyk) at the NAU 3MRP competition in March for her talk, The Redwood Test: How Much Are We Willing to Lose as the Climate Changes? Congratulations also to Julia Stuart (PhD, Biology) for being named a 2019-2020 NAU ARCS Foundation scholar! She and seven other NAU graduate student scientists received the award last week in Phoenix.
Andrew Richardson was named Regents' Professor at NAU, the highest rank a faculty member can achieve. Richardson studies forest science and ecophysiology and is a world-renowned expert in phenology, the study of seasonal rhythms of plants and animals in various ecosystems.

Ecoss graduate student Ali Martinez and a team of ecologists including her advisor Marks, Ecoss researchers Ben Koch and Zasha Welsh, Alex Flecker (Cornell University) and Steve Thomas (University of Nebraska) constructed a system of miniature streams whose temperatures Martinez can manipulate. The team studies how nutrients will move in the food chain of warming streams. The Arizona Daily Sun featured the experiment (nicknamed the Kraken) in a top story March 26, 2019.

Doctoral candidate Elaine Pegoraro designed an experiment to measure how microbes respond to fresh carbon addition at different depths in soil collected from a field site near Healy, Alaska. Essentially, she made glucose additions to the soil three times throughout the course of a year. The results were published this month in Soil Biology and Biochemistry. Pegoraro’s findings suggest that plants may contribute to some soil carbon loss by releasing glucose from their roots into soil. Read the full NAU article here
Former Ecoss Postdoctoral researcher Natasja van Gestel, now at Texas Tech University, and Bruce Hungate and Paul Dijkstra from ECOSS are using deglaciated area in Antarctica to investigate plants and microbial responses to warming. Two graduate students will be integral to the success of the study: Kelly McMillen (Texas Tech University) and Alicia Purcell (ECOSS, Northern Arizona University). Over 90% of the glaciers on the western Antarctic Peninsula have retreated with current, unprecedented warming rates – warming rates here are more than 4 times faster compared to the global average. Why study here? The land ecosystems are far less complex in Antarctica compared to land areas elsewhere, thereby making Antarctic soils more tractable to test scientific hypotheses about the links between carbon balance and those who influence it: the plants and microbes. The scientists are implementing a warming experiment by...
Ecoss's Yiqi Luo and Andrew Richardson and Ecoss affiliate Greg Caporaso (Pathogen and Microbiome Institute) have been named as ‘Highly Cited Researchers’ in 2018 by Clarivate Analytics. The list, drawn from the top 1% of scientific citations over the last decade, offers a benchmark of researchers’ influence within and across 21 scientific fields. Richardson was recognized for his publications in Environment and Ecology as well as in Agriculture, Luo in Environment and Ecology, and Caporaso in Microbiology.
What does the latest IPCC report mean for Ecoss? Center kicks off conversation on climate change, action
On November 1, Ecoss gathered at Root Public House in Flagstaff to discuss the recent report from the Intergovernmental Panel on Climate Change (IPCC) on warming and what it means for the research center’s work. The report, built on over 6000 scientific references, was a warning bell for scientists and policymakers when it was issued in October. Impacts from warming are highly non-linear, the authors found, and tipping points nearer than previously assumed. The report demonstrated that the previously accepted threshold of 2˚ will not prevent irreversible damage to societies and natural systems and indicated that the global community has 12 years in which to reduce emissions to keep warming under 1.5˚C. Nearly 30 faculty, students, staff, and postdocs joined in this first conversation, shared ideas about what climate leadership looked like, and brainstormed ways that Ecoss might respond to the report. The Center is now seeking ideas from all members...
Ecoss Assistant Research Professor Christina Schädel talks to KNAU and explains what the latest IPCC Special Report on 1.5° warming means for Arizona. Schädel was a contributing author to the report. Short excerpt from the interview: KNAU: What kind of changes are we seeing from climate change here in Arizona? Schädel: Imagine if we have any more days in Phoenix for example where temperatures go above 100 degrees F, and there will be even more when it goes above 115. So we have this already now sometimes in the summer, and it’s not pleasant, and if we have even more, you have skyrocketing air conditioning costs, for example. Another aspect is that the water supply in Arizona is going to change drastically and it’s going to become very unreliable….. Every place will see some form of climate change. It will...
