Long-term warming alters carbohydrate degradation potential in temperate forest soils
(American Society for Microbiology, 2016-09-02)
As Earth's climate warms, soil carbon pools and the microbial communities that process them may change, altering the way in which carbon is recycled in soil. In this study, we used a combination of metagenomics and bacterial ...
Correction to “Importance of carbon-nitrogen interactions and ozone on ecosystem hydrology during the 21st century”
(American Geophysical Union, 2009-08-22)
Soil hydraulic response to land-use change associated with the recent soybean expansion at the Amazon agricultural frontier
Clearing for large-scale soy production and the displacement of cattle-breeding by soybeans are major features of land-use change in the lowland Amazon that can alter hydrologic properties of soils and the runoff generation ...
N budgets and aquatic uptake in the Ipswich River basin, northeastern Massachusetts
(American Geophysical Union, 2004-11-05)
We calculated N budgets and conducted nutrient uptake experiments to evaluate the fate of N in the aquatic environment of the Ipswich River basin, northeastern Massachusetts. A mass balance indicates that the basin retains ...
Modeling coupled biogeochemical cycles
(Ecological Society of America, 2011-02)
Organisms require about 30 essential elements to sustain life. The cycles of these elements are coupled to one another through the specific physiological requirements of the organisms. Here, I contrast several approaches ...
Composition and carbon dynamics of forests in northeastern North America in a future, warmer world
(NRC Research Press, 2009-02-13)
Increasing temperatures, precipitation extremes, and other anthropogenic influences (pollutant deposition, increasing carbon dioxide) will influence future forest composition and productivity in the northeastern United ...
Emerging opportunities and challenges in phenology : a review
(John Wiley & Sons, 2016-08-18)
Plant phenology research has gained increasing attention because of the sensitivity of phenology to climate change and its consequences for ecosystem function. Recent technological development has made it possible to gather ...
Processing arctic eddy-flux data using a simple carbon-exchange model embedded in the ensemble Kalman filter
(Ecological Society of America, 2010-07)
Continuous time-series estimates of net ecosystem carbon exchange (NEE) are routinely made using eddy covariance techniques. Identifying and compensating for errors in the NEE time series can be automated using a signal ...
Burn severity influences postfire CO2 exchange in Arctic tundra
(Ecological Society of America, 2011-03)
Burned landscapes present several challenges to quantifying landscape carbon balance. Fire scars are composed of a mosaic of patches that differ in burn severity, which may influence postfire carbon budgets through damage ...
Eutrophication in Portuguese estuaries evidenced by δ15N of macrophytes
Terrestrial inputs of nitrogen in estuaries are increasing and altering salt marsh primary production, plant communities and associated biota. We used N isotope ratios and %N in Spartina maritima, Halimione portulacoides, ...
