This dissertation addresses the ecology and systematics of ectomycorrhizal (EM) fungi in
recently discovered EM forests of Guyana. Ectomycorrhizal associations are poorly known in …

Ecologically important ectomycorrhizal (EM) associations are poorly known from equatorial
rain forests of South America. Recent field studies in the Pakaraima Mountains of western …

Ectomycorrhizal (ECM) plants and fungi can be diverse and abundant in certain tropical
ecosystems. For example, the primarily paleotropical ECM plant family Dipterocarpaceae is …

Ectomycorrhizal (ECM) fungi historically were considered poorly represented in Neotropical
forests but in the central Guiana Shield substantial areas are dominated by leguminous …

The ectomycorrhizal (EM) canopy tree Dicymbe corymbosa (Fabaceae subfam.
Caesalpinioideae) forms monodominant forests in the Pakaraima Mountains of western …

Mycorrhizal fungi, because of their obligate symbiotic interaction with plant roots, may either
promote or restrict plant diversity depending on broad or narrow plantfungus relationships …

The Neotropics have recently emerged as an important region for studies of tropical
ectomycorrhizal (ECM) fungi. Specific neotropical areas with high ECM host tree densities …

Ectomycorrhizal (ECM) fungi form highly diverse communities in temperate forests, but little
is known about their community ecology in tropical ecosystems.• Using anatomotyping and …
