Effects of Fire on Ectomycorrhizal Fungi in Fennoscandian Boreal Forests
Fire, the primary natural disturbance factor in Fennoscandian boreal forests, is considered to have exerted major selection pressure on most boreal forest organisms. However, recent studies show that few ectomycorrhizal (EM) fungi appear to have evolved post-fi re adaptations, no succession of EM fungi following fi re is apparent after low intensity fi res, and only two EM fungal taxa exclusive...
متن کاملStudy of ectomycorrhizal fungi with beech trees in highland beech forests (Farim, Mazandaran province)
In this study, the ectomycorhizal fungi from beech trees in highland beech forests of Farim (Mazandaran province) were identified based on extraction of DNA from roots and sequencing the ITS region of nuclear ribosomal DNA. For this purpose, in the altitude of 1500-2100 meters A.S.L, 30 plot and one plant per each plot were selected randomly and samples were taken from roots in depths of 10 cm ...
متن کاملCompost - N recovery : 15 N natural abundance quantitative approach Caio
The remarkable influence of organic inputs, such as manure and compost, on dN values of growing plants suggests the possible use of N natural abundance as a tracer of N. Thus, using N natural abundance might be possible to estimate compost-N recovery as an alternative method to the use of N-enriched materials. The objective of this study was to verify the feasibility of using dN value to esti...
متن کاملMechanism for Ectomycorrhizal Fungi in Neotropical Lowland Forests?
Mycorrhizas are symbiotic associations between plant roots and fungi. They are divided into different categories depending on morphological characteristics and the identity of the fungi and plants (Smith & Read, 2008). In tropical rainforests, most tree species are associated with arbuscular mycorrhizas (AM) (Alexander, 1989). Neotropical tree species belonging to confirmed ectomycorrhizal (EcM...
