16. Biomass, community structure and phosphorus uptake of ectomycorrhizal fungi in response to phosphorus limitation and nitrogen deposition
Abstract : High levels of nitrogen (N) deposition might result in a transition from N to phosphorus (P) limitation in high latitude forests. Thiscould have fundamental consequences for forest production, nutrient acquisition and nutrient leaching. READ MORE

17. The use of molecular markers for identifying species diversity and functional variation of ectomycorrhizal fungi
Abstract : Ectomycorrhiza (EM) is a symbiosis between soil living fungi and the roots of woody plants. EM fungal communities are important in forest nutrient cycling, they are species rich and their structures vary between habitats and over time. READ MORE

18. Impact of root and mycorrhizal exudation on soil carbon fluxes : influence of elevated CO2 and metals
Abstract : The thesis concerns the behavior of root and ectomycorrhizal (ECM) exudates. In particular, the dynamics of soluble low molecular weight (LMW) organic compounds such as organic acids (LMWOAs), amino acids, monosaccharides, and dissolved organic carbon (DOC) have been studied. READ MORE

19. Ectomycorrhizal Fungal Mycelial Dynamics and its Role in Forest Soil Carbon Cycling
Abstract : Most boreal tree species rely on root-associated ectomycorrhizal fungi for nutrient acquisition, in exchange the trees allocate part of their photosynthetically fixed carbon (C) to these fungi. This has a feedback on soil C dynamics as mycorrhizal fungi are important in regulating soil C cycling and storage. READ MORE

20. External Mycelia of Mycorrhizal Fungi - responses to elevated N in forest ecosystems
Abstract : Most plants live in symbiosis with mycorrhizal fungi. Mycorrhizal roots constitute the interface between the plant and the soil, and almost every fine root of forest trees in nitrogen-limited boreal and temperate forests is colonised by ectomycorrhizal (EM) fungi. READ MORE
