Tidal marsh plant responses to elevated CO2 , nitrogen fertilization, and sea level rise.
Elevated CO2 and nitrogen (N) addition directly affect plant productivity and the mechanisms that allow tidal marshes to maintain a constant elevation relative to sea level, but it remains unknown how these global change drivers modify marsh plant response to sea level rise. Here we manipulated factorial combinations of CO2 concentration (two levels), N availability (two levels) and relative se...
متن کاملThe contributions of land-use change, CO2 fertilization, and climate variability to the Eastern US carbon sink
Atmospheric measurements and land-based inventories imply that terrestrial ecosystems in the northern hemisphere are taking up significant amounts of anthropogenic carbon dioxide (CO2) emissions; however, there is considerable disagreement about the causes of this uptake, and its expected future trajectory. In this paper, we use the ecosystem demography (ED) model to quantify the contributions ...

متن کاملDecreased leaf-miner abundance in elevated CO2: reduced leaf quality and increased parasitoid attack.
Most studies on the effects of elevated CO2 have focused on the effects on plant growth and ecosystem processes. Fewer studies have examined the effects of elevated CO2 on herbivory, and of these, most have examined feeding rates in laboratory conditions. Our study takes advantage of an open-top CO2 fertilization study in a Florida scrub-oak community to examine the effects of elevated CO2 on h...
متن کاملGeothermal Projects in Turkey: Extreme Greenhouse Gas Emission Rates Comparable to or Exceeding Those from Coal-fired Plants
Geothermal power projects in Turkey are outliers for this technology because of their very high CO2 emissions rates (800-1600 g/kWhr) which are comparable to or significantly exceed those from coal-fired power generation (940-980 g/kW-hr). A “typical” 50 MW geothermal project in Turkey producing 1000 g/kW-hr CO2 emits 1,200 tonnes per day of CO2 to the atmosphere. CO2 is discharged to the atmos...
