Warming Reduces Carbon Losses from Grassland Exposed to Elevated Atmospheric Carbon Dioxide
The flux of carbon dioxide (CO2) between terrestrial ecosystems and the atmosphere may ameliorate or exacerbate climate change, depending on the relative responses of ecosystem photosynthesis and respiration to warming temperatures, rising atmospheric CO2, and altered precipitation. The combined effect of these global change factors is especially uncertain because of their potential for interac...
متن کاملFragmentations of protonated arginine, lysine and their methylated derivatives: concomitant losses of carbon monoxide or carbon dioxide and an amine.
The fragmentation pathways of protonated arginine, protonated N(alpha),N(alpha)-dimethylarginine, the N(alpha),N(alpha),N(alpha)-trimethylarginine ion, three protonated N(epsilon),N(epsilon)-dimethyllysines, and three permanent lysine ions in which the charge is fixed by trimethylation are reported. Ion assignment was facilitated by (15)N-labeling and deuterium substitution. The chemistries are...
متن کاملExperimental drought in a tropical rain forest increases soil carbon dioxide losses to the atmosphere.
Climate models predict precipitation changes for much of the humid tropics, yet few studies have investigated the potential consequences of drought on soil carbon (C) cycling in this important biome. In wet tropical forests, drought could stimulate soil respiration via overall reductions in soil anoxia, but previous research suggests that litter decomposition is positively correlated with high ...
متن کاملNutrient additions to a tropical rain forest drive substantial soil carbon dioxide losses to the atmosphere.
Terrestrial biosphere-atmosphere carbon dioxide (CO(2)) exchange is dominated by tropical forests, where photosynthetic carbon (C) uptake is thought to be phosphorus (P)-limited. In P-poor tropical forests, P may also limit organic matter decomposition and soil C losses. We conducted a field-fertilization experiment to show that P fertilization stimulates soil respiration in a lowland tropical ...
