Increased weathering of soil minerals induced by elevated CO2 concentration has been reported previously in temperate areas. However, this has not been well documented for the tropics and subtropics. We used model forest ecosystems in open-top chambers to study the effects of CO2 enrichment alone and together with nitrogen (N) addition on inorganic carbon (C) losses in the leachates. Three years of exposure to an atmospheric CO2 concentration of 700\u00a0ppm resulted in increased annual inorganic C export through leaching below the 70\u00a0cm soil profile. Compared to the control without any CO2 and N treatments, net biocarbonate C (HCO3                         \u2212-C) loss increased by 42%, 74%, and 81% in the high CO2 concentration treatment in 2006, 2007, and 2008, respectively. Increased inorganic C export following the exposure to the elevated CO2 was related to both increased inorganic C concentrations in the leaching water and the greater amount of leaching water. Net annual inorganic C (HCO3                         \u2212-C and carbonate C: CO3                         2\u2212-C) loss via the leaching water in the high CO2 concentration chambers reached 48.0, 49.5, and 114.0\u00a0kg\u00a0ha\u22121 y\u22121 in 2006, 2007, and 2008, respectively, compared with 33.8, 28.4, and 62.8\u00a0kg\u00a0ha\u22121\u00a0y\u22121 in the control chambers in the corresponding years. The N addition showed a negative effect on the mineral weathering. The decreased inorganic C concentration in the leaching water and the decreased leaching water amount induced by the high N treatment were the results of the adverse effect. Our results suggest that tropical forest soil systems may be able to compensate for a small part of the atmospheric CO2 increase through the accelerated processing of CO2 into HCO3                         \u2212-C during soil mineral weathering, which might be transported in part into ground water or oceans on geological timescales.", "keywords": ["Environmental sciences", "Biological sciences", "13.

It has been suggested that the C, N and P cycles could become uncoupled under rapid climate change because of the different degrees of control exerted on the supply of these elements by biological and geochemical processes. Climatic controls on biogeochemical cycles are particularly relevant in arid, semi-arid and dry sub-humid ecosystems (drylands) because their biological activity is mainly driven by water availability. The increase in aridity predicted for the twenty-first century in many drylands worldwide may therefore threaten the balance between these cycles, differentially affecting the availability of essential nutrients. Here we evaluate how aridity affects the balance between C, N and P in soils collected from 224 dryland sites from all continents except Antarctica. We find a negative effect of aridity on the concentration of soil organic C and total N, but a positive effect on the concentration of inorganic P. Aridity is negatively related to plant cover, which may favour the dominance of physical processes such as rock weathering, a major source of P to ecosystems, over biological processes that provide more C and N, such as litter decomposition. Our findings suggest that any predicted increase in aridity with climate change will probably reduce the concentrations of N and C in global drylands, but increase that of P. These changes would uncouple the C, N and P cycles in drylands and could negatively affect the provision of key services provided by these ecosystems.", "keywords": ["0301 basic medicine", "Nitrogen", "Biolog\u00eda", "Climate Change", "Carbon Cycle", "Soil", "03 medical and health sciences", "Ecological Impacts of Climate Change", "XXXXXX - Unknown", "Ecological impacts of climate change and ecological adaptation", "Biomass", "Desiccation", "Ecosystem", "Soil Chemistry (excl Carbon Sequestration Science)", "2.
