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 […]
Clouds and aerosols increase the fraction of global solar irradiance that is diffuse light. This phenomenon is known to increase the photosynthetic light use efficiency (LUE) of closed-canopy vegetation by redistributing photosynthetic photon flux density (400–700 nm) from saturated, sunlit leaves at the top of the canopy, to shaded leaves […]
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 […]
Albedo, the reflectance of sunlight from earth’s surface, is an important moderator of climate because it determines whether solar energy is locally absorbed or re-radiated to space. Ecoss-associated research characterized the albedo and other energy fluxes of various landscapes to demonstrate that human land-use decisions can alter surface energy fluxes […]
PhD and MS positions in Ecosystem Ecology are available in the Center for Ecosystem Science in Society (Ecoss) at Northern Arizona University. The Ecoss mission is to conduct high-impact, innovative research on ecosystems and how they respond to and shape environmental change, to train next-gen scientists, and to communicate discovery […]
For two species of oak, we determined whether increasing atmospheric CO2 concentration (Ca) would decrease leaf mitochondrial respiration (R) directly, or indirectly owing to their growth in elevated Ca, or both. In particular, we tested whether acclimatory decreases in leaf-Rubisco content in elevated Ca would decrease R associated with its […]
Forestry – including afforestation (the planting of trees on land where they have not recently existed), reforestation, avoided deforestation, and forest management – can lead to increased sequestration of atmospheric carbon dioxide and has therefore been proposed as a strategy to mitigate climate change. However, forestry also influences land-surface properties, […]

Sunrise over the subtropical oak woodland, elevated CO2 experiment at the Kennedy Space Center, Florida. The experiment used open-top chambers to increase CO2 concentrations, with paired chambers with no extra CO2 serving as controls. The experiment ran from 1996-2007. Photo credit: Bert Drake.
