Project description
In the proposed research work mycorrhizal Scots pine trees will be exposed to increased temperature, N deposition and above- or below-ground herbivory stress in the field and chamber experiments. The main aim is to study how the mycorrhizal N uptake and subsequent assimilation and thereby C allocation to below-ground components are altered due to various abiotic and biotic environmental factors. In a separate chamber experiment also the effect of mycorrhiza identity and age on N and C cycles in mycorrhiza-tree-system under abiotic and biotic stress will be studied. At the moment there are severe gaps in the understanding of how mycorrhizal symbiosis, and especially N and C cycling in northern forests, are affected by climate warming, moderate N deposition and herbivory stress. The results can be used in data compilations for modelling of mycorrhiza-plant N and C fluxes in a changing world.
