Management of forests for carbon uptake is an important tool in the effort to slow the increase in atmospheric CO2 and global warming. However, some current policies governing forest carbon credits actually promote avoidable CO2 release and punish actions that would increase long-term carbon storage. In fire-prone forests, management that […]
Longstanding land-management policies of complete wildfire suppression on wild lands were intended to prevent catastrophic wildfires through constant human monitoring and intervention. However, when combined with policies that prohibit logging or thinning in protected areas, total fire suppression can lead to giant conflagrations anyhow, as the buildup of fuel materials […]
In this article, author comments on the effect of climate change in the arctic region. It mentions that the temperatures of arctic region are rising fast, and permafrost is thawing. Further it mentions that the northern soils will release huge amounts of carbon into the atmosphere from permafrost soils.

Background Forests can sequester carbon dioxide, thereby reducing atmospheric concentrations and slowing global warming. In the U.S., forest carbon stocks have increased as a result of regrowth following land abandonment and in-growth due to fire suppression, and they currently sequester approximately 10% of annual US emissions. This ecosystem service is […]
Forests sequester carbon from the atmosphere, helping mitigate climate change. In fire-prone forests, burn events result in direct and indirect emissions of carbon. High fire-induced tree mortality can cause a transition from a carbon sink to source, but thinning and prescribed burning can reduce fire severity and carbon loss when […]
New findings published in the journal Nature by Ecoss researcher Andrew Richardson offer some of the first experiment-based evidence that a warmer world will significantly shift ecosystem-wide growing seasons, putting plants at higher risk during extreme temperature swings. Richardson and a team of collaborators conducted a unique experiment in boreal […]
Boreal wildfires are increasing in intensity, extent, and frequency, potentially intensifying carbon emissions and transitioning the region from a globally significant carbon sink to a source. The productive southern boreal forests of central Canada already experience relatively high frequencies of fire, and as such may serve as an analog of […]
PhD and MS positions in Ecosystem Ecology are available in the Center for Ecosystem Science and Society (Ecoss) at Northern Arizona University. Graduate student benefits include a stipend (teaching assistantship or research assistantship), tuition waiver, health insurance, and payment of non-tuition fees. The Ecoss mission is to conduct high-impact, innovative […]
Our aim is to use elevational gradients to quantify the relationship between temperature and ecosystem functioning. Ecosystem functions such as decomposition, nutrient cycling and carbon storage are linked with the amount of microbial biomass in the soil. Previous studies have shown variable relationships between elevation and soil microbial biomass (SMB). […]
