Saltmarsh plant responses to eutrophication
(John Wiley & Sons, 2016-10-20)
In saltmarsh plant communities, bottom-up pressure from nutrient enrichment is predicted to increase productivity, alter community structure, decrease biodiversity, and alter ecosystem functioning. Previous work supporting ...
Microbial associations with macrobiota in coastal ecosystems : patterns and implications for nitrogen cycling
(John Wiley & Sons, 2016-05-02)
In addition to their important effects on nitrogen (N) cycling via excretion and assimilation (by macrofauna and macroflora, respectively), many macrobiota also host or facilitate microbial taxa responsible for N ...
Correction to “Importance of carbon-nitrogen interactions and ozone on ecosystem hydrology during the 21st century”
(American Geophysical Union, 2009-08-22)
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 ...
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 ...
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 ...
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 ...
Chlorophyll fluorescence tracks seasonal variations of photosynthesis from leaf to canopy in a temperate forest
Accurate estimation of terrestrial gross primary productivity (GPP) remains a challenge despite its importance in the global carbon cycle. Chlorophyll fluorescence (ChlF) has been recently adopted to understand photosynthesis ...
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 ...
