Carbon isotopes in terrestrial ecosystem pools and CO2 fluxes.
Stable carbon isotopes are used extensively to examine physiological, ecological, and biogeochemical processes related to ecosystem, regional, and global carbon cycles and provide information at a variety of temporal and spatial scales. Much is known about the processes that regulate the carbon isotopic composition (delta(13)C) of leaf, plant, and ecosystem carbon pools and of photosynthetic an...
متن کاملBiases in regional carbon budgets from covariation of surface fluxes and weather in transport model inversions
Recent advances in atmospheric transport model inversions could significantly reduce uncertainties in land carbon uptake through the assimilation of CO2 concentration measurements at weekly and shorter timescales. The potential of these measurements for reducing biases in estimated land carbon sinks depends on the strength of covariation between surface fluxes and atmospheric transport at these...
متن کاملPersonal Carbon Budgets for Transport
Australia’s transport greenhouse gas (GHG) emissions are high and continue to grow, with current levels approximately one-third higher than in 1990 and increasing by around 1% annually. Efforts to curtail and reverse this growth have not been successful to date. In recent times, national policy development and debate has centred on market-based mechanisms to reduce GHG emissions, namely an emis...
متن کاملSoil warming, carbon-nitrogen interactions, and forest carbon budgets.
Soil warming has the potential to alter both soil and plant processes that affect carbon storage in forest ecosystems. We have quantified these effects in a large, long-term (7-y) soil-warming study in a deciduous forest in New England. Soil warming has resulted in carbon losses from the soil and stimulated carbon gains in the woody tissue of trees. The warming-enhanced decay of soil organic ma...
متن کاملCarbon Fluxes in the Rhizosphere
Terrestrial ecosystems are intimately connected to atmospheric CO2 levels through photosynthetic fixation of CO2, sequestration of C into biomass and soils, and the subsequent release of CO2 through respiration and decomposition of organic matter. Considering all the pools and fluxes of C within ecosystems, C-cycling belowground is increasingly being recognized as one of the most significant co...
