A critical need exists to develop ecologically sustainable forest management approaches that incorporate climate change adaptation to sustain carbon sequestration, fiber production, and other ecological goods and services provided by managed forests (Millar et al. 2007; Alexander and Perschel 2009).
In our simulation, elevated CO2 concentration made the dominant contribution to the projected sustained carbon sink, given the fact that NBP becomes a carbon source when the effect of CO2 is excluded (NBP from E noco2 in Table 4), which is consistent with the findings from French grassland sites [27].
Breakdown of starch provides a carbon source for the dark period and its rate is highly controlled to assure sustained carbon supply to metabolism during the night [30].
Since the stalk is associated with the ability to scavenge for nutrients [15], the initiation of stalk development upon sustained carbon starvation might prime the cell for quick resumption of cell cycle progression once nutrients become available.
The sustained carbon accumulation on the West Cascades land base contributes to the regional forest carbon sink.
We found that C. glabrata cells engulfed by mouse macrophages experience a mild oxidative stress and sustained carbon starvation.
Fulvic acid is believed to originate as a product of microbial metabolism, although it is not synthesized as a life-sustaining carbon or energy source.
In about 600 million years, the level of will fall below the level needed to sustain C3 carbon fixation photosynthesis used by trees.
This hypothesis was sustained by carbon balance measurements based on experimental measures of CO2 [ 28].
In view of climate change there is a general agreement to preserve and maintain carbon pools of unmanaged forests, as those sustain substantial carbon pools.
At the operating temperature of about 980 °C (1,800 °F), the oxygen reacts with coal to form carbon dioxide, thereby producing heat to sustain the endothermic steam-carbon and carbon dioxide-carbon reactions.
