Oak savanna is one of the most endangered ecosystems of North America, with less than 0.02% of its original area remaining. Here we test whether oak savanna supports a unique community of ectomycorrhizal fungi, a higher diversity of ectomycorrhizal fungi or a greater proportional abundance of ascomycete fungi compared with adjacent areas where the absence of fire has resulted in oak savanna con...

Ectomycorrhizal fungi are mutualistic symbionts of many forest trees and play a major role in nutrient uptake. They form diverse communities in boreal forest soils but functional differences within this group of fungi remain largely unknown. We study ectomycorrhzal fungi in mineral soil to determine how abiotic preferences influence their spatial distribution in stratified soil profiles. This i...

(Species richness of arbuscular mycorrhizal fungi in forests with Araucaria in Southern Brazil). This study aimed to characterize species richness of arbuscular mycorrhizal fungi (AMF) in three distinct forests with Araucaria angustifolia (native forest, reforestation with A. angustifolia and plantation with Pinus taeda) in the “Floresta Nacional de São Francisco de Paula”, State of Rio Grande ...

Fungi regulate key nutrient cycling processes in many forest ecosystems, but their diversity and distribution within and across ecosystems are poorly understood. Here, we examine the spatial distribution of fungi across a boreal and tropical ecosystem, focusing on ectomycorrhizal fungi. We analyzed fungal community composition across litter (organic horizons) and underlying soil horizons (0-20 ...

A list of 128 taxa (127 species) of lichens, 6 species of lichenicolous fungi and 2 non-lichenized fungi traditionally included in lichenological literature from the virgin forest Rajhenavski Rog and its surroundings in the southeastern part of Slovenia is presented. The lichen Gyalecta derivata, the lichenicolous fungus Homostegia piggotii, and the non-lichenized fungus Mycomicrothelia pachnea...

The mountain pine beetle (MPB), the most serious pest of lodgepole pine in mountainous western Canada, spread northeastward into lodgepole · jack pine hybrids in the boreal forest of Alberta in 2006. The MPB vectors three species of blue-stain fungi, which contribute to the success of the beetles. These fungi were isolated from MPB larvae and galleries in several lodgepole · jack pine stands in...

The species diversity and distribution of 3 ecological groups of fungi (viz., foliar endophytes, phellophytes, and leaf litter fungi of 6 tree hosts of a dry thorn forest and 6 tree hosts of an evergreen forest of southern India) were studied. As the methods of sampling and the isolation procedure were maintained constant, the results could be compared across hosts and fungal assemblages. The d...

Fungi associated with seeds of tropical trees pervasively affect seed survival and germination, and thus are an important, but understudied, component of forest ecology. Here, we examine the diversity and evolutionary origins of fungi isolated from seeds of an important pioneer tree (Cecropia insignis, Cecropiaceae) following burial in soil for five months in a tropical moist forest in Panama. ...

Leaf litter samples of 12 dicotyledonous tree species (belonging to eight families) growing in a dry tropical forest and in early stages of decomposition were studied for the presence of litter fungi. Equal-sized segments of the leaves incubated in moist chambers were observed every day for 30 d for the presence of fungi. Invariably, the fungal assemblage on the litter of each tree species was ...
