Ectomycorrhizal fungi in mineral soil
Ectomycorrhizal fungi are mutualistic symbionts of many forest trees and play a major role in nutrient uptake. They form diverse communities in boreal forest soils but functional differences within this group of fungi remain largely unknown. We study ectomycorrhzal fungi in mineral soil to determine how abiotic preferences influence their spatial distribution in stratified soil profiles. This i...
متن کاملCarbon cycling in soil
www.frontiersinecology.org © The Ecological Society of America S contain a huge and dynamic pool of carbon (C), that is a critical regulator of the global carbon budget. As the repository for more than three-fourths of the earth’s terrestrial C, soils store 4.5 times the amount of C contained in vegetation (Lal 2004). Small changes in the processes governing soil C cycling have the potential to...
متن کاملDecomposition by ectomycorrhizal fungi alters soil carbon storage in a simulation model
Carbon cycle models often lack explicit belowground organism activity, yet belowground organisms regulate carbon storage and release in soil. Ectomycorrhizal fungi are important players in the carbon cycle because they are a conduit into soil for carbon assimilated by the plant. It is hypothesized that ectomycorrhizal fungi can also be active decomposers when plant carbon allocation to fungi is...
متن کاملDecadally cycling soil carbon is more sensitive to warming than faster-cycling soil carbon.
The response of soil organic carbon (SOC) pools to globally rising surface temperature crucially determines the feedback between climate change and the global carbon cycle. However, there is a lack of studies investigating the temperature sensitivity of decomposition for decadally cycling SOC which is the main component of total soil carbon stock and the most relevant to global change. We tackl...
متن کاملMicrobial control over carbon cycling in soil
A major thrust of terrestrial microbial ecology is focused on understanding when and how the composition of the microbial community affects the functioning of biogeochemical processes at the ecosystem scale (meters-to-kilometers and days-to-years). While research has demonstrated these linkages for physiologically and phylogenetically "narrow" processes such as trace gas emissions and nitrifica...
