Abstract:: Symbiotic associations are established between non-leguminous (actinorrhizal) nitrogen-fixing flowering plants and two categories of microorganisms: mycorrhizal fungi and a filamentous actinomycete. The actinomydete induces nodule formation and produces nitrogenase, the enzyme responsible for the reduction of atmospheric nitrogen to a form available to higher plants. The mycorrhizal fungus is found...

Creator:: Blanchard, Joseph H.
Abstract:: Ectomycorrhizal (ECM) fungi of the genera Piloderma and Ramaria form dense hyphal mats in the organic and upper mineral soil layers, respectively, in coniferous forest floors of the Pacific Northwest. Previous studies have determined that fungal mats change the chemical, physical, and biological properties of the soil within. Little information...

Creator:: Danielson, Rachel E.
Abstract:: Forest harvest persists as one of the most globally important industries, and crucially provides raw wood products for both building and fuel materials. Mechanistically complex abiotic and biotic processes curb ecosystem recovery following timber harvest and it is of great importance to understand the effects of this practice on biogeochemical...

Creator:: Cappellazzi, Jed E.
Abstract:: Ectomycorrhizal fungi (EmF) form symbioses with trees. These symbioses profoundly influence forest ecology. Certain EmF form specialized profusions of hyphae, known as ectomycorrhizal fungal mats (mats) which are visible to the naked eye, alter forest soil biogeochemistry, substantially contribute to soil microbial biomass/respiration and support unique microbial communities. Piloderma and...
