Snow is important for local to global climate and surface hydrology, but spatial and temporal heterogeneity in the extent of snow cover make accurate, fine-scale mapping and monitoring of snow an enormous challenge. We took 184,453 daily near-surface images acquired by 133 automated cameras and processed them using crowdsourcing and […]
Plant water potential Ψ is regulated by stomatal responses to atmospheric moisture demand D and soil water availability W, but the timescales of influence and interactions between these drivers of plant Ψ are poorly understood. Here, we quantify the effects of antecedent D and W on plant Ψ in the […]
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 […]
Scoring The goal of this challenge is to encourage people to participate in diversity-related events and to actively think about and discuss how to create a more inclusive work environment in Ecoss. There are plenty of ways for your team to earn points (see below for suggested activities). Remember to […]
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 […]
The flux of CO2 from the soil to the atmosphere (soil respiration, Rsoil) is a major component of the global carbon (C) cycle. Methods to measure and model Rsoil, or partition it into different components, often rely on the assumption that soil CO2 concentrations and fluxes are in steady state, implying that Rsoil is equal to […]
Land surface phenology (LSP) has been widely retrieved from time series of various satellite instruments in order to monitor climate change and ecosystem dynamics. However, any evaluation of the quality of LSP data sets is quite challenging because the in situ observations on a limited number of individual trees, shrubs, […]
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 […]

Land-use conversions and elevated temperature can impact on carbon dioxide (CO2) and nitrous oxide (N2O) emissions, both of which are important greenhouse gasses (GHGs). Afforestation activity has increased significantly over the last century with a significant focus in recent years directed at offsetting GHG emissions, as forests have a large […]
