Interactions among Soil Biota in Coniferous Ecosystems
Fogel, R., 1988. Interactions among soil biota in coniferous ecosystems. Agric. Ecosystems Environ., 24: 69-85. The dominance of ectomycorrhizae in most coniferous forest ecosystems profoundly alters the classical concept of the role of exudation and rhizodeposition of cell fragments in the formation of the rhizosphere. In the unaltered, non-ectomycorrhizal rhizosphere the soluble exudates and ...
متن کاملPlant-soil interactions in a changing world
Evidence is mounting to suggest that the transfer of carbon through roots of plants to the soil plays a primary role in regulating ecosystem responses to climate change and its mitigation. Future research is needed to improve understanding of the mechanisms involved in this phenomenon, its consequences for ecosystem carbon cycling, and the potential to exploit plant root traits and soil microbi...
متن کاملInteractions between soil structure and fungi
The spatial organisation of soils is crucially important in affecting belowground function, and the associated delivery of ecosystem services. Fungi constitute an important part of the soil biomass. As well as playing key roles in nutrient cycling and biotic interactions, they are also intimately involved in soil structural dynamics. Fungi mediate the formation of soil structure at a variety of...
متن کاملElement interactions limit soil carbon storage.
Rising levels of atmospheric CO2 are thought to increase C sinks in terrestrial ecosystems. The potential of these sinks to mitigate CO2 emissions, however, may be constrained by nutrients. By using metaanalysis, we found that elevated CO2 only causes accumulation of soil C when N is added at rates well above typical atmospheric N inputs. Similarly, elevated CO2 only enhances N2 fixation, the m...
متن کاملGlobal change effects on plant-soil interactions
As plants of different life-forms generate different soil communities, assessment of climate change impacts on soil communities and soil services must consider how these impacts are conditioned by the vegetation above. We investigated how soil communities under different plant species in the same ecosystem respond to global change. In a heathland FACE-experiment, we modelled projected global ch...
