Below-ground carbon flux and partitioning: global patterns and response to temperature
1. The fraction of gross primary production (GPP) that is total below-ground carbon flux (TBCF) and the fraction of TBCF that is below-ground net primary production (BNPP) represent globally significant C fluxes that are fundamental in regulating ecosystem C balance. However, global estimates of the partitioning of GPP to TBCF and of TBCF to BNPP, as well as the absolute size of these fluxes, r...
متن کاملModeling Carbon Allocation below Ground
Belowground carbon expenditure has been difficult to measure, and even more so to predict. Root growth is influenced by both direct effects on plant metabolism and indirect effects of soil drying and interactions with soil organisms. In Concord grape, crop load may compete with root growth when soil moisture is not limiting. Root lifespan also is difficult to predict but some success can be ach...
متن کاملWarming-related increases in soil CO2 e ux are explained by increased below-ground carbon flux
The universally observed exponential increase in soil-surface CO2 e ux (‘soil respiration’; FS) with increasing temperature has led to speculation that global warming will accelerate soilorganic-carbon (SOC) decomposition1, reduce SOC storage, and drive a positive feedback to future warming2. However, interpreting temperature–FS relationships, and so modelling terrestrial carbon balance in a wa...
متن کاملHow planting density and grazing intensity affect the above- and below-ground carbon pools in a dryland ecosystem?
Climate change is known as one of the most important environmental challenges. Sequestration of carbon in terrestrial ecosystems is a low-cost option that may be available in the near-term to mitigate increasing atmospheric CO2 concentrations, while providing additional benefits. In this study, we estimated the effects of planting density and grazing intensity on the potential of Atriplex canes...
