Controls over pathways of carbon efflux from soils along climate and black spruce productivity gradients in interior Alaska
Small changes in C cycling in boreal forests can change the sign of their C balance, so it is important to gain an understanding of the factors controlling small exports like water-soluble organic carbon (WSOC) fluxes from the soils in these systems. To examine this, we estimated WSOC fluxes based on measured concentrations along four replicate gradients in upland black spruce (Picea mariana [M...
متن کاملSoil carbon stabilization along climate and stand productivity gradients in black spruce forests of interior Alaska1
The amount of soil organic carbon (SOC) in stable, slow-turnover pools is likely to change in response to climate warming because processes mediating soil C balance (net primary production and decomposition) vary with environmental conditions. This is important to consider in boreal forests, which constitute one of the world’s largest stocks of SOC. We investigated changes in soil C stabilizati...
متن کاملNonlinear responses of white spruce growth to climate variability in interior Alaska
Ongoing warming at high latitudes is expected to lead to large changes in the structure and function of boreal forests. Our objective in this research is to determine the climatic controls over the growth of white spruce (Picea glauca (Moench) Voss) at the warmest driest margins of its range in interior Alaska. We then use those relationships to determine the climate variables most likely to li...
