1. Fungal communities of West African ectomycorrhizal woodlands
Abstract : Ectomycorrhizal symbiosis is a widespread mutualist relationship between fungi and plants, often trees. It is most well-known in temperate and boreal forests, but also occurs in a variety of tropical ecosystems, including Sudanian savanna woodlands and gallery forests in West Africa. READ MORE

2. Basidiospore germination in ectomycorrhizal fungi : biochemical and ultrastructural studies with special reference to the taxon-specific germination induction in the genus Leccinum
Abstract : .... READ MORE

3. Effects of nitrogen deposition on the growth, metabolism and activity of ectomycorrhizal fungi
Abstract : Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. READ MORE

4. Ectomycorrhizal fungi: Their role in nitrogen retention and carbon sequestration in northern coniferous forests
Abstract : Almost all northern forest tree species live in symbioses with ectomycorrhizal fungi (EMF). The trees allocate up to half of the photoassimilated carbon (C) through the roots to EMF. In return EMF deliver nutrients from both inorganic and organic sources in the soil, as well as water. READ MORE

5. Interactions between ectomycorrhizal associations and bacteria
Abstract : Boreal forest podzol soils have vertically stratified horizons with different physico-chemical characteristics and high microbial diversity. Ectomycorrhizal fungi play key roles in accessing nutrients from both organic and mineral substrates. The role of associated bacteria in these processes is still poorly understood. READ MORE
