Differences in the biogeochemistry of nitrogen (N) and phosphorus (P) lead to differential losses and inputs during and over time after fire such that fire may affect nutrient limitation of primary productivity. We conducted a nutrient addition experiment in scrubby flatwoods, a Florida scrub community type, to test the hypothesis […]
Ecoss professor Michelle Mack is featured in the journal Fire as a woman leader in fire science. The article recognizes international women leaders in fire research and development. Read the article here Michelle Mack is also featured in the AZ Daily Sun as an internationally recognized contributor to NAU’s recent […]
When it comes to how climate change is impacting ecosystems, there’s no shortage of data out there. But finding enough people who know both ecology and how to interpret that data can be a different story. Ecoss affiliated professor Kiona Ogle leads the multi million dollar grant from the National […]
Ecoss ecologist Ted Schuur, who’s received a $600,000 grant from the National Science Foundation (NSF) to establish a carbon observatory at Eight Mile Lake near Denali National Park in Alaska, calls the permafrost’s massive release of greenhouse gases into the Earth’s atmosphere a “wild card,” and potentially a tipping point, […]
Understanding drivers of straw decomposition is essential for adopting appropriate management practice to improve soil fertility and promote carbon (C) sequestration in agricultural systems. However, predicting straw decomposition and characteristics is difficult because of the interactions between many factors related to straw properties, soil properties, and climate, especially under future […]
Eight Ecoss students, faculty, and staff traveled to Detroit, MI in May 2018 to present their research at the Annual Meeting of the Society for Freshwater Science. Undergraduate researcher Zasha Welsh presented a poster, as did graduate students Courtney Roush, Meghan Schrik, Jack Torresdal, and Adam Siders. Ben Koch, Victor […]
Climate warming and drying is associated with increased wildfire disturbance and the emergence of megafires in North American boreal forests. Changes to the fire regime are expected to strongly increase combustion emissions of carbon (C) which could alter regional C balance and positively feedback to climate warming. In order to […]
The boreal forest is home to one-third of the Earth’s forest cover and stores 40 percent of the planet’s terrestrial carbon. North America’s boreal forest alone, which spans the northern portion of the continent from Alaska all the way to Newfoundland, covers an astounding 1.5 billion acres—more than 2.3 million […]
After the rapid-fire madness of 15 back-to-back two-minute presentations, the audience flocked to Victor Leshyk’s screen. The topic was science-art integration, and in two minutes Victor had explained his vision about the role for the didactic in the intersection of art and passion. In the discussion session he presented his […]
Forest phenology is a multi-scale phenomenon, arising from processes in leaves and trees, with effects on the ecology of plant communities and landscapes. Because phenology controls carbon and water cycles, which are commonly observed at the ecosystem scale (e.g. eddy flux measurements), it is important to characterize the relation between […]
