Biological nitrogen (N) fixation plays an important role in terrestrial N cycling and represents a key driver of terrestrial net primary productivity (NPP). Despite the importance of N fixation in terrestrial ecosystems, our knowledge regarding the controls on terrestrial N fixation remains poor. Here, we conducted a meta-analysis (based on […]
Rubber powdery mildew caused by the foliar fungi Oidium heveae is one of the main diseases affecting rubber plantations (Hevea brasiliensis) worldwide. It is particularly serious in sub-optimal growing areas, such as Xishuangbanna in SW China. To prevent and control this disease, fungicides causing serious environmental problems are widely used. […]
An increasing number of studies showed that coverage of existing protected areas is not enough to protect biodiversity. However, to what extent and how human population density influence the geographical pattern of protected areas are not clear. Based on 2644 terrestrial nature reserves (NRs) in mainland China in 2015, correlation […]
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, […]
Bruce Hungate, Ecoss Director, Regents’ Professor, and McAllister Chair in Community, Culture, and Environment is presenting in Science on Tap on ‘Climate Change and Culture on the Colorado Plateau‘. How will climate change affect our region? How can we respond? Explore the science of climate change, its relationship to society […]
Edward A. G. Schuur, a permafrost expert at Northern Arizona University, said the study was “an important and interesting calculation of where permafrost will be at some distant point in the future as we undergo climate warming.” “What’s really important is this is based on totally different assumptions,” Dr. Schuur […]
This story in the Washington Post (June 3, 2016) provides details on a major and surprising new report from the U.S. Geological Survey. The document raises questions about what will be the true carbon consequences of Alaska’s ongoing warming. Ted Schuur, permafrost researcher at Ecoss says about the new study “It’s important to remember […]
Hurricane disturbances have profound impacts on ecosystem structure and function, yet their effects on ecosystem CO2 exchange have not been reported. In September 2004, our research site on a fire-regenerated scrub-oak ecosystem in central Florida was struck by Hurricane Frances with sustained winds of 113 km h−1 and wind gusts as high […]
Disturbance affects most terrestrial ecosystems and has the potential to shape their responses to chronic environmental change. Scrub-oak vegetation regenerating from fire disturbance in subtropical Florida was exposed to experimentally elevated carbon dioxide (CO2) concentration (+350 μl l−1) using open-top chambers for 11 yr, punctuated by hurricane disturbance in year 8. Here, we […]
